Money Prize IMSA 2025, how much has Porsche earned?

The 2025 IMSA WeatherTech SportsCar Championship concluded this weekend with the Road Atlanta race. Crowning the Porsche Penske 963 as the overall winner in the GTP LMDh category.
A well-deserved victory for Stuttgart’s manufacturer, who has been a dominant force throughout the season.
This triumph carries not only sporting significance but also enormous commercial and strategic value and prize money. Porsche aims to strengthen its presence in the American market, particularly in terms of sales.

Demonstrating itself as the strongest among manufacturers, Porsche provided substantial visibility for the numerous sponsors supporting the team this season. In particular TAG Heuer, Michelin, Ansys (Official Technology Partner), and Multimatic.

Prize Money Structure: Balanced but limited

The prize money for each race is divided into three main categories:

• Special events, such as the legendary Rolex 24;
• High-profile races, including Sebring, Watkins Glen, Indianapolis, and Road Atlanta;
• And standard calendar events.

In the Rolex 24, for example, the winner in each class earns $25,000, a figure that drops to $10,000 for other major races and remains at similar levels for the more “regular” rounds.
Prizes are awarded up to fifth place, with a total of $50,000 per class for the most prestigious events. $25,000 is the prize money for smaller ones.

IMSA Teams End-of-Year Funds and possible Earnings

Teams registered as “premium entries”, official factory-supported teams such as Porsche, BMW, Lamborghini, and Cadillac, also benefit from the end-of-year prize fund.
In the GTP and GTD PRO classes, the top five teams in the final standings share a $137,000 prize pool, with the championship-winning team receiving an additional $35,000.

A rough calculation suggests that Porsche Penske, winner of the GTP title, may have earned around $130,000 from race prizes and end-of-season bonuses, considering victories in key events like the Rolex 24 and other high-profile rounds.
While a notable sum, it barely covers the operational costs of an entire season, making it more symbolic than substantial.

The IMSA prize system does, however, reward both prestigious race victories and consistent performance across the season. This allows the most competitive teams to recoup at least part of their investments.
With strong spectator turnout in 2025, the championship appears to be in good health, suggesting that next year’s prize pools could be even more attractive.

It remains to be seen if Porsche can achieve the nearly impossible feat also winning the WEC title, where Ferrari 499P cars are unlikely to relinquish their place in a championship that has eluded Maranello since 1972.

Porsche Eyes the Future: Exiting WEC, Focusing on IMSA and Formula E

Starting in 2026, Porsche plans to exit the WEC, concentrating its efforts exclusively on the IMSA Championship.
The move is largely driven by cost optimization, as the prize money offered by endurance competitions does not come close to covering operational and development expenses.

The goal is clear: dominate a single championship, already won this year and fully familiar to Team Porsche Penske.
An additional boost to the brand’s image in 2026 comes from the entry of Manthey Racing. With the two iconic “Grello” cars, which have already achieved legendary wins in Europe, including the 24 Hours of Nürburgring.

This strategic focus positions Stuttgart to prioritize IMSA and Formula E in the coming years, leading its transition toward electric mobility, confident that this represents the inevitable—and winning—future of transportation.
