Overview
- A third-place result at Portland behind Will Power and Christian Lundgaard was enough for Alex Palou to clinch his fourth championship and third straight Astor Cup.
- Pato O’Ward’s bid for the title ended on lap 22 when a malfunction in his DI box wiring forced him to pit ten laps down and drop out of contention.
- Will Power led 78 of 110 laps to claim his first victory of the season at Portland International Raceway and deliver Team Penske’s only win of 2025.
- Power faces free-agent status after his contract with Team Penske expires on August 31.
- Palou’s eight wins this season, including his first Indianapolis 500 triumph, are the most by a series champion since 2007 and tie him with Andretti, Bourdais, and Franchitti for third on the all-time title list.
