2026 Indianapolis 500

2025 2027 | 2025 | 2027 | | 2025 | 2027 | |

The 2026 Indianapolis 500 (branded as the 110th Running of the Indianapolis 500 presented by Gainbridge for sponsorship reasons) was an IndyCar Series race that took place on May 24, 2026, at the Indianapolis Motor Speedway in Speedway, Indiana. The race was the seventh of the NTT IndyCar Series season. The month of May activities formally began with the Sonsio Grand Prix on the combined road course on May 9. The race was televised on Fox. This was the first "500" since the Fox Corporation acquired a one-third stake in INDYCAR and Indianapolis Motor Speedway parent company Penske Entertainment in August 2025.

Practice began on May 12, and Time Trials were scheduled for May 16–17. The first day of qualifying, however, was rained out. Carb Day, the traditional final day of practice took place on May 22. The annual Pit Stop Challenge, however, was halted and cancelled due to rain. A full-field open test was held April 28–29, which included rookie orientation. Álex Palou was the defending winner, and three-time defending IndyCar Series champion. Palou qualified for the pole position, his second career Indy pole.

For the third year in a row, a driver attempted to complete "Double Duty," as Katherine Legge attempted to compete in both the Indianapolis 500 and Coca-Cola 600 on the same day. After a crash attempting to avoid a spinning Ryan Hunter-Reay on Lap 18, Legge reached Charlotte and raced the Coca-Cola 600, finishing the latter 12 laps behind the winner and in 31st place, last among cars still in the race.

The Carb Day practice event on Friday, May 22 honored the late NASCAR driver Kyle Busch, who died from complications with pneumonia on Thursday, May 21. Dale Coyne Racing also decided to honor Kyle Busch by decorating Romain Grosjean's No. 18 car with the same number font Busch used throughout his NASCAR career. Busch was also remembered at the Coca-Cola 600 later that night.

Felix Rosenqvist of Meyer Shank Racing dominated late and beat Team Penske's David Malukas to the finish line by the closest margin of victory in race history (0.0233 seconds) to win his first Indianapolis 500.

Many more records were broken as well. The race featured a record-breaking 70 lead changes, the most in race history. The previous record was 68, set in 2013. The previous closest finish came in 1992 when Al Unser Jr. beat Scott Goodyear by 0.043 seconds. Álex Palou and Scott Dixon traded the lead a record-breaking 26 times. The previous record of lead changes between the same two drivers was 18, between James Hinchcliffe and Ryan Hunter-Reay, set in 2016. Santino Ferrucci also completed the full 500-mile distance for a record-breaking eighth consecutive year. 2026 marked the fifth time in Indy 500 history that the lap leader on the final lap (David Malukas) failed to win. Felix Rosenqvist became the first 34-year-old to win an Indy 500 since Helio Castroneves did so in 2009.

Turn one at the Indianapolis Motor Speedway (pictured in 2018).

The Indianapolis 500, commonly called the Indy 500, is held at the Indianapolis Motor Speedway, a 2.5-mile (4.02 km) paved oval. First held in 1911, it is currently a points-paying race of the NTT IndyCar Series. The event is contested by "Indy cars", a formula of professional-level, single-seat, open cockpit, open-wheel, purpose-built race cars. The race is the most prestigious event of the IndyCar calendar, and one of the oldest and most important automobile races in the world. The race traditionally has a field of 33 cars.

According to Speedway president Doug Boles, track maintenance crews have been investigating bumps in Turn 2 since 2019. During track evaluations prior to the 2025 race, the Turn 2 bump in question was considerably higher than in the past. The pavement was pressed in an attempt to reduce the severity. In July 2025, during the Brickyard 400, the severity of the bumps in Turn 2 were reported by drivers and crew chiefs during the track walk and all sessions.

On September 23, 2025, construction crews excavated the section of track in question. It was determined that bricks originally installed in 1909 (that had been paved over by asphalt in 1937) had expanded and split due to moisture, which raised the pavement. The damaged bricks were removed and a new base was applied. The section of the track was repaved, followed by diamond grinding to blend the new section with the adjacent asphalt. The track was allowed to cure for four weeks before the late October Speedway tests for Firestone.

• A new entity, titled IndyCar Officiating, Inc. has been created, tasked with governing over the IndyCar Series and Indy NXT. It includes a three-person Independent Officiating Board (IOB) consisting of: Ray Evernham, Raj Nair (Ford), and Ronan Morgan (FIA). Scot Elkins will serve as Managing Director of Officiating. The move separates race control and technical inspection from Penske Entertainment, which owns INDYCAR and the Indianapolis Motor Speedway, in an effort to eliminate perceived conflicts of interest. In 2025, Team Penske was penalized for technical infractions during Indy 500 qualifying, resulting in two cars being moved to the back of the grid, monetary fines, and points deductions. The controversy led to the dismissal of team president Tim Cindric, and widespread calls for officiating reform. In January 2026, Team Penske revealed that Cindric had returned to the team as a strategist.
• Tire ramp flaps will be mandatory on all cars. The flaps are designed to deploy in a spin and/or during rearward movement in order to reduce the likelihood of lift, preventing the car from becoming airborne. The flaps are similar in concept to the roof flaps introduced in NASCAR in 1994.
• Each entry is permitted 31 sets of tires for the entirety of the event, plus 5 additional sets for use during the Open Test. This is down from 32 sets and 8 sets, respectively in 2025. During the Rookie Orientation Program/Refresher Tests session, drivers taking rookie tests receive three additional sets, and drivers taking refresher tests receive two additional sets, for use during that session only.
• A modified qualifying format was announced on May 11, due to a lack of entries to necessitate the Last Chance Qualifying session that had been featured in previous years. During Saturday qualifying, those qualifying positions 1–15 will advance to Sunday qualifying sessions, while positions 16–33 will be locked in to their positions. During Sunday qualifying, the drivers qualified positions 10–15 on Saturday will participate in a "Final 15" session, in which the fastest three cars will advance to the Top 12 session later in the day, while positions 13–15 will be locked in to their spots. The remaining session will proceed as in previous years; the fastest six cars in the Top 12 session will move on to the Fast Six, while positions 7–12 are locked. The Fast Six session will then determine starting positions 1–6.
• During the final 60 minutes of practice each day, drivers will be permitted to practice entering the pit area off of turn four. This simulates the method of entering the pits used on race day. At all other times, drivers must still enter the pits at the warm-up lane in turn three – with exceptions only for emergency service. Previously, pitting off of turn four (during practice) was only allowed during Post-Qualifying Practice (Monday) and on Carb Day.

Online financial services company Gainbridge signed an initial four-year deal for presenting sponsorship of the Indianapolis 500 from 2019 to 2022. A multi-year extension was signed in 2022. On November 6, 2025, Gainbridge signed another multi-year contract extension. Terms of the deal were undisclosed.

The 2026 Indianapolis 500 was the seventh race of the 2026 NTT IndyCar Series season. Four different drivers won the first six races of the season. Álex Palou won the season opener at St. Petersburg. Josef Newgarden won at Phoenix, and Kyle Kirkwood won at Arlington. Palou won for the second and third time this season at Alabama and Long Beach. The Sonsio Grand Prix on the Indianapolis Motor Speedway road course was won by Christian Lundgaard. It was the final race before the "500". Palou holds a 27-point margin over Kirkwood in the championship points standings going into the Indianapolis 500 - the fourth year in a row Palou has led the points standings going into the "500".

Four-time IndyCar Series champion Álex Palou (pictured in 2024) is the defending Indy 500 winner.

Four-time Indy 500 winner Hélio Castroneves (pictured in 2022) has the most previous starts in the field with 25.

All entries utilized a spec Dallara DW12 chassis with the UAK-18 universal aero kit and the 2020-adopted aeroscreen. Honda (HRC US) and Chevrolet (Ilmor) are the engine providers. Firestone is the exclusive tire supplier. This will be the second year of hybrid energy recovery system powertrains at Indianapolis.

The official entry list was released on May 11, with 33 confirmed entries. The list included 25 full-time IndyCar Series entries, and eight one-off or "Indy-only" entries.

Andretti Global was planning to run a fourth car, in an "Indy-only" entry, with the #98. Colton Herta, who is competing full-time in Formula 2 in 2026, was the likely driver. The original Formula 2 calendar had no races scheduled for May, which would have allowed Herta to compete at Indy. However, due to the Iran war, which resulted in the cancellation of two races in Bahrain and Saudi Arabia, the Formula 2 schedule was revised with the addition of races in Miami and Canada, the latter of which was scheduled for the same day as the 500. Herta was therefore no longer available due to the scheduling conflict, and Andretti Global thus elected to not run the car.

PREMA Racing had two Chevrolet engine leases for the 2026 IndyCar Series season, but is currently undergoing an ownership shake-up which has left the team in limbo regarding competing in any of the 2026 events. On April 10, it was announced PREMA would not enter at Indianapolis. As a result, their two engines were released to other teams.

This will be the first time since 2022 that no bumping will take place. Devlin DeFrancesco, who raced full-time for RLL in 2025, and Stefan Wilson, who last competed in 2023, were two drivers who aggressively pursued rides before the last entry was filled by Legge.

• R  Indianapolis 500 rookie

• 1 Marcus Armstrong's No. 66 entry will feature Acura badging in place of normal Honda branding. The entry will still use the same engine as all other Honda entries.

Mick Schumacher is one of four rookies entered. His father Michael Schumacher won the U.S. Grand Prix at Indy five times.

Rookie rules for the Indianapolis 500 include the mandate that a driver pass a supervised high-speed oval test before he/she is allowed to participate in the official Rookie Orientation Program (ROP) at the Indianapolis Motor Speedway. Approved venues for the initial high-speed oval track test include Texas Motor Speedway, Homestead–Miami Speedway, and a few other select venues.

The Rookie Orientation Program at Indianapolis consists of three phases. For phase 1, each driver is required to complete ten laps between 205–210 mph (330–338 km/h), while demonstrating satisfactory car control, proper racing line, and safe interaction with other cars on the circuit. The laps do not have to be consecutive. Phase 2 is fifteen laps between 210–215 mph (338–346 km/h), and phase 3 is fifteen laps over 215 mph (346 km/h). Veteran drivers that have not competed in an IndyCar oval race since the previous year's Indy 500 are required to take a refresher test. The refresher test consists of phase 2 and phase 3 of the aforementioned rookie test.

On October 20–21, 2025, the Speedway organized private testing. Álex Palou (Ganassi) and Pato O'Ward (Arrow McLaren) participated in tire tests for Firestone, including evaluating the newly repaved section of track to remove bumps in turn 2. A new tire compound was developed in order to address weight balance issues stemming from the hybrid system first used at the Speedway in 2025. Alexander Rossi (ECR) and Takuma Sato (RLLR) tested brake and damper components for speedway-specific braking systems (used at Indianapolis and Nashville).

The series hosted a high-speed oval rookie evaluation test at Nashville Superspeedway on November 6, 2025. Two drivers participated: Dennis Hauger (Coyne) and Caio Collet (Foyt). No incidents were reported. Both drivers completed their evaluations and were approved to take the Rookie Orientation Program at the April Open Test at Indianapolis.

Rahal Letterman Lanigan Racing conducted a private oval evaluation test for rookie driver Mick Schumacher at Homestead–Miami Speedway on February 4, 2026. Schumacher, guided by driver coach Ryan Briscoe, took his first laps on an oval, completing 97 laps without incident. He posted a top lap of 194 mph.

Conor Daly (pictured in 2023) was fastest on Day 1 of the Open Test.

The first day of open testing was scheduled for April 28. After a five-minute period for install laps, the track was first made available for veterans from 10:05 a.m. to 12 p.m. Rookie Orientation and Refresher Tests took place from 12 p.m. to 2 p.m. The track was then open to all cars from 2 p.m. to 6 p.m. During the final hour, "hot pits" were in effect, allowing drivers to practice entering/exiting the pits, and crews were allowed to practice pit stops.

• Weather: 64 °F (18 °C); Mostly cloudy early, fair late
• Summary: The first veteran session began as scheduled at 10:05 a.m. A total of 24 drivers turned laps during the session, with Josef Newgarden running fastest at 223.415 mph (359.552 km/h). One minor incident occurred during the session, when Romain Grosjean collided with a bird, bringing out a caution for debris, and causing some clean up of his car to be needed.

The Rookie Orientation and Refresher Test session began immediately following the veteran's test, with nine drivers scheduled to participate. Jack Harvey, Ed Carpenter, Ryan Hunter-Reay, and Hélio Castroneves completed their veteran refresher tests, while Caio Collet, Jacob Abel, and Mick Schumacher completed all three phases of their rookie tests. Dennis Hauger completed phases 1 and 2 of his rookie test, and was given permission to complete the final phase during the full-field session later in the afternoon. Katherine Legge, the final driver required to complete a refresher test, experienced clutch problems and was unable to complete any laps at speed. As a result, she was not permitted to participate in the full-field session.

The full-field test session began at 2:00 p.m., with the track open until 6:00 p.m. Conor Daly set the fastest speed of the day, running a lap at 225.394 mph (362.736 km/h) late in the day. His teammate Jack Harvey ran the fastest "no-tow" lap — a lap without the assistance of aerodynamic drafting — at 220.318 mph (354.567 km/h). Only one incident was reported. At 5:34 p.m., Christian Rasmussen came to a stop on track at the exit of turn 2 with a loose right-rear wheel. The car was undamaged, but needed to be towed off of the race track.

Caio Collet (pictured in 2020) was fastest on Day 2 of the Open Test.

The morning session was originally scheduled for 10 a.m. to 12 p.m. and the afternoon session was scheduled for 1 p.m. to 5 p.m. An additional special session from 12 p.m. to 1 p.m. was announced the previous evening for Katherine Legge to complete her refresher test. However, overnight rain delayed the start of testing by one hour and fifteen minutes. The scheduled was revised, shifting the early session to 11:15 a.m. to 1:15 p.m. Legge's ROP session was moved to 1:15 p.m., and the afternoon session was changed to 2:15 p.m. to 5 p.m. After some observed weepers in the new pavement section at the exit of turn two on Tuesday, some minor patching was done overnight. In the final hour, "hot pits" were once again in effect, with drivers this time permitted to enter the pit lane off of turn four, to simulate the race day configuration.

• Weather: 63 °F (17 °C); cloudy to mostly cloudy
• Summary: Day two of testing began at 11:15 a.m. after track drying from overnight rain was completed. Rookie driver Caio Collet was fastest during the morning session, running a lap at 226.381 mph (364.325 km/h). This lap would be the fastest of the day, as it was not matched during the afternoon session. Jack Harvey turned the fastest "no-tow" lap for the second day in a row during the morning session, running a lap at 221.112 mph (355.845 km/h).

From 1:15 p.m. to 2:15 p.m., the track was made available for Katherine Legge to complete her veteran refresher test. Legge successfully completed the refresher test, and was cleared to take part in further testing.

From 2:15 p.m. until 5:00 p.m. the track was open to all drivers. Josef Newgarden was fastest in the afternoon session, turning a lap at 225.617 mph (363.095 km/h). One significant incident occurred at 3:27 p.m. Jack Harvey suffered a major engine failure in turn four. The car billowed large amounts of smoke and briefly caught fire before Harvey brought the car to a stop in the pit lane. Earlier, at 2:58 p.m., a brief yellow came out after a fox ran across the track in turn one, and was narrowly missed by Takuma Sato.

Kyle Kirkwood had the fastest "non-tow" lap on opening day.

• Weather: 77 °F (25 °C), Fair
• Summary: The opening day of practice began at 12:00 p.m., with the track open until 6:00 p.m. Despite having handling issues early in the day, Álex Palou turned the fastest lap late in the session with a speed at 225.937 mph (363.610 km/h). Kyle Kirkwood turned the fastest "no-tow" lap with a speed of 222.062 mph (357.374 km/h). Palou came into the pits suddenly at 4:13 p.m. complaining of a problem in the right-rear. The car was wheeled back to the garage area where the crew partially tore it down to determine what was wrong. After short consultation, the car was wheeled back out, and Palou set his aforementioned fast lap. One notable mechanical failure occurred for Ed Carpenter, whose engine failed during his installation lap early in the session. The engine was changed, and Carpenter participated in running in the later part of practice.

There were no major incidents during the session. However, there were two yellows for track inspection due to cut tires. Hélio Castroneves and Graham Rahal both suffered punctures, but both were able to return to the pits without incident. After an engine issue, Scott McLaughlin's team was preparing to install a new engine in time for Wednesday's practice session.

• Weather: 66 °F (19 °C), Mostly cloudy
• Summary: The track was once again open from 12:00 p.m. to 6:00 p.m. for Wednesday practice. The day saw significantly cooler temperatures and windier conditions than opening practice. Conor Daly ran the fastest lap of the day at 228.080 mph (367.059 km/h). Pato O'Ward turned the fastest "no-tow" lap at 221.409 mph (356.323 km/h). There were no major incidents reported. Two engine changes were reported on during the day. Scott McLaughlin's team changed the engine on his car overnight between Tuesday and Wednesday, while at the end of the day Alexander Rossi's team were reported to have started changing the engine on his car. These, combined with Ed Carpenter's engine failure the previous day, marked three Chevrolet engines needing changed in the first two days of practice.

Pato O'Ward turned the fastest lap on Thursday.

• Weather: 65 °F (18 °C), Fair
• Summary: Thursday practice ran from 12:00 p.m. to 6:00 p.m. With qualifying approaching, several teams began attempting qualifying simulations, despite cars not yet being permitted to have qualifying boost levels. Pato O'Ward turned the fastest lap of the day, running at 227.308 mph (365.817 km/h). The fastest "no-tow" lap came from Takuma Sato, who ran a lap at 223.828 mph (360.216 km/h) without aerodynamic drafting. There were no major incidents reported. There was a total of 1,469 laps logged by the 33 cars, the lowest day-total thus far for the week. With good weather on all three days, and no track time lost to rain, some teams elected to run fewer laps on Thursday in order to save their tire allotment for Friday and for qualifying.

• Weather: 68 °F (20 °C), Morning rain, then cloudy in the afternoon turning to fair in late afternoon
• Summary: Practice was originally scheduled for 12 p.m. to 6 p.m. However, morning rain delayed the start until 2:00 p.m. Due to the delay, the session was extended by one hour to 7:00 p.m. For Fast Friday practice, teams were permitted to increase turbocharger boost pressures to qualifying levels – 1,500 mbar (44.3 inHg). With the increased boost levels, teams focused on simulated qualification running. Felix Rosenqvist ran the fastest lap of the day, with a lap at 233.372 mph (375.576 km/h). Rosenqvist also had the fastest four-lap run – a simulation of a four-lap qualifying run – with an average speed of 232.828 mph (374.700 km/h). Scott McLaughlin turned the fastest "no-tow" lap of the session at 232.674 mph (374.453 km/h), which was also the third fastest lap overall of the day. There were no major incidents reported. Another Chevrolet engine failure was reported, as Santino Ferrucci experienced a failure with 55 minutes left in the session.

After the session, the random draw to determine qualifying order was held in the Pagoda area. Scott Dixon drew the first spot in line.

• Weather: 69 °F (21 °C), Scattered thunderstorms

• Summary: Persistent rain throughout the day prevented any track running on the scheduled first day of qualification. All qualifications were shifted to Sunday, and the scheduled "Fast 15" session was discarded in the revised condensed schedule.

• Weather: 83 °F (28 °C), Fair

• Summary: With the first day of qualification rained out, a revised schedule was announced for Sunday, with the scheduled "Top 15" session discarded. During the first session, which began at 12 p.m., all entries were given one guaranteed attempt. The cars qualifying in positions 1–12 in the first session advanced to the Top 12 session later in the day, while those in positions 13–33 were locked in to their positions. At 4 p.m., the Top 12 session will be held, where the top six qualifiers will advance to the final Fast Six qualifying, while positions 7–12 will be locked in to their positions. At 6:00 p.m., the Top Six session will start, which will determine the top six starting positions.

A one-hour practice session was held before qualifying, beginning at 9:30 a.m. Only 14 entries turned laps during the session. One minor incident occurred when Takuma Sato drifted high in turn 3 and brushed the outside wall. The incident brought out a caution period, but Sato's car was not significantly damaged. Christian Rasmussen was the fastest in the session, turning a lap at 232.255 mph (373.778 km/h).

Full field qualifying began at noon. Felix Rosenqvist was the fastest in the session, running a four-lap average at 232.599 miles per hour (374.332 km/h). Rosenqvist was the only qualifier whose run was above 232 mph (373 km/h). Caio Collet was the fastest rookie qualifier at 231.419 mph (372.433 km/h), good enough for seventh fastest in the session. Collet was the only rookie to advance to the Top 12 session. Also advancing to the Top 12 session were David Malukas, Conor Daly, Scott McLaughlin, Rinus VeeKay, Alexander Rossi, Scott Dixon, Pato O'Ward, Santino Ferrucci, Álex Palou, and Kyffin Simpson.

• 1 The times set by Caio Collet and Jack Harvey were later disallowed due to technical infringements on both cars.

• Summary: The Top 12 session began just before 4:30 p.m. Drivers qualified in reverse order of how they had qualified in the previous full field session. Felix Rosenqvist was fastest in the Top 12 session at 232.065 mph (373.472 km/h). Álex Palou greatly improved from his first run, and was second fastest in the Top 12 session. David Malukas, Santino Ferrucci, Pato O'Ward, and Alexander Rossi concluded the top six, with all advancing to the final Fast Six session.

• 1 The time set by Caio Collet was later disallowed due to a technical infringement on his car.

• Summary: The Fast Six session began at 6:00 p.m. Drivers qualified in reverse order of their results from the Top 12 session. Álex Palou qualified on pole position with a four-lap average of 232.248 mph (373.767 km/h). It was Palou's second pole qualification at the Indianapolis 500. Alexander Rossi qualified second, securing his first front-row start since 2017, while David Malukas earned his first front row start with the third fastest time. Despite being fastest in both of the first two session, Felix Rosenqvist was unable to find the speed to challenge for pole, and was only fourth fastest.

Hours after qualifying ended, Indycar announced that the cars of Caio Collet and Jack Harvey had failed technical inspection due to using unapproved hardware for the Dallara-supplied energy management system. Both entries had their qualifying times disallowed, and were moved to the rear of the starting grid.

• Weather: 81 °F (27 °C); Mostly cloudy turning to thunderstorms late
• Summary: A two-hour session was scheduled from 1 p.m. to 3 p.m. At 1:29 p.m., the first major incident of the month occurred. Alexander Rossi lost control and spun in turn two, and made heavy contact with the outside wall. Pato O'Ward spun in avoidance, but collided with Rossi's car. Behind them, Romain Grosjean lost control of his car while trying to slow for the incident, and also impacted the wall. All three drivers climbed from their cars under their own power, but Rossi was held for extended evaluation at the infield care center and was later transported to IU Methodist Hospital for further evaluation. Rossi was released later that night with finger and ankle injuries. He was not immediately cleared to drive again, but still intended to drive on Carb Day and race day. After cleanup, the session was resumed, but ultimately ended at 2:06 p.m. due to thunderstorms. Josef Newgarden was fastest in the session, running a lap at 226.198 mph (364.030 km/h).

• Weather: 67 °F (19 °C) Cloudy, light rain
• Summary: The two-hour final practice session was scheduled for 11 a.m. to 1 p.m. All 33 cars participated, including Alexander Rossi, who was cleared to drive after his crash on Monday. The field completed 2,169 laps without incident. Josef Newgarden, turned the fastest lap, while Scott Dixon completed the most laps (96). Despite rain in the forecast, the entire two-hour session was run to completion. Only one yellow occurred, when Marcus Ericsson was slow on the course with a loose rear wheel. Ericsson's car was wheeled back to the garage area, but he was able to return to the track later in the session.

The second annual Wienie 500 was held as part of Carb Day festivities. Six Oscar Mayer Wienermobiles, each representing a different regional dog took part in a two-lap, 5-mile race from a standing start. For the 2026 event, Sonoran Dog was replaced by Corn Dog. Andy Richter served as the "Commander in Beef" and gave the command to start engines.

The #01 Chicago Dog took the lead at the start and led into turn one. As the field exited turn two and started down the backstretch, Chicago Dog threw a hard block on the #05 Seattle Dog, forcing it to the inside apron. The #03 Slaw Dog took the lead going into turn three, and led the first lap. Down the backstretch on lap 2, Chili Dog, Chicago Dog, and New York Dog went three-wide. The #02 New York Dog emerged as the leader. Down the frontstretch, Chili Dog attempted a slingshot pass on the outside, but came up short. New York Dog held on to win by about .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);clip-path:polygon(0px 0px,0px 0px,0px 0px);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}3⁄4 length.

The 47th annual Pit Stop Challenge was scheduled for Friday May 22, after the completion of Carb Day practice. For 2026, the event once again picked up sponsorship from Oscar Mayer and was officially the "Oscar Mayer $150,000 Pit Stop Challenge" for sponsorship reasons. After four of the first-round matchups were completed, a light rain began to fall. The competition was halted to wait out the shower, but the rain began to fall harder, and the event was cancelled; it was the first Pit Stop Challenge to be cancelled due to rain since 2008.

At the start of the race, Alexander Rossi moved in to the lead ahead of pole sitter Álex Palou. The two then exchanged the lead between themselves for the opening several laps. At lap 18, the first caution of the race came when Ryan Hunter-Reay spun in turn two and made contact with the wall. Katherine Legge also spun to try to avoid Hunter-Reay and impacted the inside wall on the backstraight. During the yellow, most of the field made their first pit stops. Palou emerged first of those that pitted, while Rossi suffered a slow pitstop and dropped farther down in the running order. Rinus VeeKay, Romain Grosjean, and Caio Collet did not pit, and moved to the lead of the race. Racing resumed at lap 26, with Grosjean moving to the lead of the race. Behind them, Ed Carpenter lost control of his car in turn one after being three-wide with Takuma Sato, resulting in him impacting the outside wall and bring out the race's second caution period.

Racing resumed at lap 31, with Collet briefly taking the lead before those that had not stopped at the first caution needed to pit. Palou moved back in to the lead, and began to cycle with Conor Daly. At the next round of stops, Felix Rosenqvist moved in to second place, while Palou held the lead. A few laps later, Scott Dixon passed Rosenqvist for second, and Palou and Dixon began to exchange the lead between each other, working as teammates to try to hold the lead. At lap 92, the third caution of the race came as Will Power suffered a mechanical failure and spun on the pit lane exit lane on the fluid left by the car. Power did not make contact with any walls, but was out of the race. At the same time as the caution came, Alexander Rossi came to a stop on pit lane with the car briefly catching fire. Rossi was also out of the race. The entire field made pit stops during the caution period, with Dixon emerging in the lead ahead of Palou and Josef Newgarden, while David Malukas was fourth. The caution period was extended due to small amounts of rain at the north end of the track. At lap 105, the race was briefly stopped to allow the rain to pass.

Once the rain passed, the race resumed under yellow. The green flag was shown again at lap 110, with Palou and Malukas jumping ahead of Dixon at the restart. Conor Daly moved up to third position, while Palou and Malukas exchanged the lead ahead. At lap 116, the caution came out again for a brief rain shower, but no race stoppage was needed. Racing resumed at lap 124, but almost immediately the caution was needed again, as Josef Newgarden spun in turn four and heavily impacted the outside wall. During this caution, several drivers elected to pit, most notably Felix Rosenqvist, Pato O'Ward, and Marcus Armstrong, which put them on an alternate strategy to the other leaders.

Racing resumed at lap 132, with the leaders going four-wide in to turn one passing Malukas. Conor Daly emerged as the leader, with Scott McLaughlin and Palou behind. Both McLaughlin and Palou passed Daly later and began to exchange the lead, but at lap 147 Malukas moved his way back in to the lead. Soon after, all leaders pitted, which moved Rosenqvist and O'Ward on the alternate strategy to the lead. O'Ward and Rosenqvist pitted with 36 and 34 laps to go respectively, handing the lead back to the battling Malukas and Palou, but eliminating their final pit stops while Malukas and Palou would still need to pit. Beginning at lap 175, the leading cars of the primary strategy pitted, giving the lead initially to O'Ward, but on lap 185 Rosenqvist moved in to the lead and began pulling away, while Malukas and Palou remained over 16 seconds behind after their final stops.

On lap 192, the six caution of the race came as Caio Collet collided with the outside wall in turn two. IndyCar officials chose to stop the race to allow Collet's car to be removed and attempt to ensure a green-flag finish. After cleaning Collet's car, the race resumed under caution. On lap 196, the green flag came out again, with Marcus Armstrong, who had been running third on the same strategy as Rosenqvist, moving in to the lead, while David Malukas moved in the second ahead of Rosenqvist. Behind them, Mick Schumacher drifted wide in turn one and brushed the outside wall, bringing out the race's seventh and final caution. Schumacher's car was not severely damaged and he continued driving, allowing IndyCar to clear the track quickly and have a one-lap shootout to finish. The green and white came out on lap 200, with Malukas jumping to the lead, while Rosenqvist ran around the outside of Armstrong. Rosenqvist and Armstrong remained side-by-side through the whole lap until turn four, when Rosenqvist moved ahead. Despite having been side-by-side, Rosenqvist was still able to generate a run on Malukas, and in a photo-finish Rosenqvist pushed ahead to take victory. The final margin of victory was 0.0233 seconds, setting a new record for closest finish in Indianapolis 500, surpassing the old mark of 0.043 seconds that had been set in 1992. The race also saw 70 lead changes, setting a new record for most lead-changes in a single running of the race.
