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. ^[1] On January 14, 2025, Fox announced its broadcast team for the 2025 season. Will Buxton was named the lead commentator 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. ^[2]

On September 23, 2024, IndyCar announced its first ever charter system, which will begin in 2025 and 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 are 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 would remain open, and no teams would have a guaranteed entry in the 33-car starting field. ^{[N 1] [5]}

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 to compete against the two Prema cars for the two 'open' spots in the field. ^[6]

On February 11, Doug Boles was named as the new president of IndyCar, replacing Jay Frye. Boles will also continue to hold his role as president of Indianapolis Motor Speedway. ^[7]

Confirmed entries

The following teams, entries, and drivers are contracted to compete in the 2025 NTT IndyCar Series season. All teams will use a spec Dallara DW12 chassis with 2018 universal aero kit and Firestone tires.
