The 2025 NTT IndyCar Series was the 114th official championship season of American open-wheel racing and the 30th season under IndyCar Series sanction. Its showcase event was the 109th running of the Indianapolis 500, which was won by Chip Ganassi Racing driver Álex Palou for the first time. Palou also entered the season as the back-to-back defending champion and earned a three-peat. He became the first driver to win the Indianapolis 500 and season driver's title in the same year since Dario Franchitti in 2010.
Background and series news After IndyCar's television contract with NBC Sports lapsed in 2024, the series signed a new agreement with Fox Sports that saw all races being covered on the Fox broadcast network. On January 14, 2025, Fox announced its broadcast team for the 2025 season. Will Buxton was named the lead commentator, who previously covered Formula One, while Townsend Bell and James Hinchcliffe, who previously served as analysts for NBC and are also former IndyCar drivers, retained their roles in the new lineup.
On September 12, 2024, IndyCar announced that the Firestone Tire and Rubber Company had signed an extension to remain as the series' sole tire supplier.
On September 23, 2024, IndyCar announced its first ever charter system, which began in 2025 and will extend until 2031. 25 charters were awarded among all teams that competed full-time in the 2024 season, with a maximum of 3 for each team. Chartered entries were qualified to compete for the 22 Leaders Circle contracts. At every race on the calendar outside of the Indianapolis 500, starting fields were limited to 27 cars, and chartered entries were guaranteed a starting position. Qualification for the Indianapolis 500 remained open, and no teams had a guaranteed entry in the 33-car starting field.
As a new entrant in the series, PREMA Racing was excluded from receiving charters. If a race event outside of the Indianapolis 500 were to feature additional cars, those would have had to compete against the two PREMA cars for the two 'open' spots in the field.
On February 11, Doug Boles was named as the new president of IndyCar, replacing Jay Frye. Boles also continued to hold his role as president of Indianapolis Motor Speedway.
Numerous technical violations found during qualifying and the race for the Indianapolis 500, particularly involving the cars of Team Penske, led to the start of an overhaul of IndyCar's officiating system. The series announced after the race that they would create an independent officiating board for race stewarding and technical inspections, in part due to increasing concerns with Roger Penske owning both the IndyCar series and a competing team in the series. The new officiating board was targeted to be ready for the 2026 season. Further, the series announced their intent to begin using a scanning system during inspections to assist with finding possible rules infractions on cars. The new scanning process was rolled out at Portland, where four cars were impounded after the race and scanned to check for technical compliance.
On July 31, 2025, Fox Sports parent company Fox Corporation announced that it had acquired a one-third stake in IndyCar parent company Penske Entertainment. As part of the acquisition, Fox Sports' TV contract was extended to 2030.
Confirmed entries The following teams, entries, and drivers were contracted to compete in the 2025 NTT IndyCar Series season. All teams used a spec Dallara DW12 chassis with 2018 universal aero kit and Firestone tires.
