Alex Palou won Portland by 4.1167 seconds for his sixth victory of 2026 and a 110-point championship lead with five races left. The full catch-up: Lundgaard's last-to-first miracle at Road America, Arrow McLaren's first 1-2 at Mid-Ohio, Palou conquering the ovals at Nashville, McLaren's blockbuster 2027 signing of Scott Dixon and Felix Rosenqvist, and the five-race sprint to the title.
