The NTT IndyCar Series raced on the permanent road course at the Thermal Club in Thermal, California in 2024 and 2025.
In 2024, a non-championship exhibition event called the $1 Million Challenge was held. It was designed to be a "made-for-TV" all-star event and was won by Alex Palou.
For the 2025 season, the race became a full championship points race and was called the Thermal Club IndyCar Grand Prix.
