2025 Grand Prix of Portland betting picks & race predictions

The NTT IndyCar Series heads north to Oregon for the Grand Prix of Portland on August 8-10, the penultimate road course of the 2025 calendar and a vital stop in the final push to the championship.

Portland International Raceway — a tight, 12-turn, 1.964-mile natural road course — has been the stage for high drama over the years, including Will Power’s wire-to-wire dominance in 2024 and a record-setting three-wide finish back in 1997.

With just three events left, the title race feels more like a coronation. Alex Palou is a short-priced favorite at -131.58 odds with the top online betting sites to win this weekend and clinch his fourth IndyCar title in five years. His recent road course form has been nearly flawless, and a win in Portland would mathematically shut the door on the rest of the field.

Behind him, Scott McLaughlin has quietly built momentum with four straight top-10s at Portland and a win here in 2022. He’s still chasing his first victory of the year and remains one of Team Penske’s most reliable road course performers.

Will Power, last year’s Portland winner, returns with a point to prove — both to fans and possibly to his team — as speculation grows about his 2026 plans.

Santino Ferrucci and Christian Rasmussen are value plays worth watching. Ferrucci started on pole at Portland in 2024 and has two podiums this season, while Rasmussen has quietly climbed the oval charts and could surprise if he qualifies well.

Expect tire strategy and first-lap chaos in the Festival Curves to shape Sunday’s result. And if we get a late safety car — as is often the case here — the door may crack open for someone to steal the show.

IndyCar Portland GP betting predictions

Alex Palou to win

Palou has owned 2025. Portland suits his smooth, efficient driving style, and he’ll have eyes only for the checkered flag and the championship trophy. With the title in reach, expect a composed yet commanding drive from the Spaniard and take the -131.58 available with BetOnline.

Will Power top-three finish

Power was dominant here in 2024, leading over 100 laps. His 2025 form has been inconsistent, but this circuit plays to his strengths: technical precision and track position. If Team Penske deliver a clean strategy, Power has every chance to repeat last year’s magic.

Santino Ferrucci top-six finish

Ferrucci’s chaotic-yet-effective style makes him a dark horse at high-risk venues like Portland. With a strong qualifying run, he could be in the mix — and his previous pole here proves he knows how to deliver at this track. He thrives in unpredictable races, and Portland’s first-lap chaos could play right into his hands.
