Note: The Penske Entertainment editorial staff is looking back at the five biggest moments of 2025 in INDY NXT by Firestone in this year-end series, with one installment appearing on the site per day in countdown fashion from Dec. 27-31.

The 2025 INDY NXT by Firestone season continued the development series’ upward trajectory, showcasing expanding fields, increased competition and unprecedented national exposure.

With an average of 19.4 starters per race, INDY NXT delivered one of its deepest and most diverse grids in over a decade, extending the growth trend that began after the 2022 season and the series rebrand in 2023.

For the second consecutive year, 27 drivers made at least one start, two more than in 2023 and 10 more than in 2022, signaling renewed interest from both established programs and emerging contenders. This modern era of INDY NXT has produced the largest fields since 2009. Among the 2025 highlights was the return of Chip Ganassi Racing to the series for the first time since 2007, adding another heavyweight organization to an already competitive paddock.

That momentum continues into 2026. Ed Carpenter Racing and AJ Foyt Racing both rejoin the series through technical partnerships, with ECR aligning with Cape Motorsports and Foyt partnering with HMD Motorsports. Juncos Hollinger Racing also returns as a standalone entrant, while new team Cusick Morgan Motorsports will make its INDY NXT debut as a two-car effort in collaboration with HMD. The influx of teams and driver development programs reinforces INDY NXT’s position as the strongest pipeline into the NTT INDYCAR SERIES.

Competitive depth defined the 2025 campaign on track. Five different drivers representing three teams reached Victory Lane, while nine drivers from four organizations earned podium finishes. Qualifying was just as tight, with four different pole winners. The oval schedule produced some of the most dramatic racing of the season, as three of the four events featured a final lead change within the last 20 laps.

Off the track, 2025 marked a breakthrough season for INDY NXT’s visibility. For the first time, the entire schedule aired live on national television. Thirteen races were broadcast on FOX Sports’ FS1 and one on FS2, with every practice and qualifying session also receiving live coverage across the FOX Sports platforms. This comprehensive television package resulted in exponential audience growth, with average viewership more than five times higher than in 2024.

With deeper fields, expanding team participation, thrilling racing and its largest-ever broadcast audience, the 2025 season cemented INDY NXT by Firestone as a premier proving ground for future NTT INDYCAR SERIES stars setting the stage for even more momentum in 2026.
