The 2026 IMSA SportsCar Championship (known for sponsorship reasons as the 2026 IMSA WeatherTech SportsCar Championship) is a motor racing championship, which will be the 56th racing season sanctioned by the International Motor Sports Association and traces its lineage back to the 1971 IMSA GT Championship. It will also be the thirteenth season of the IMSA SportsCar Championship since the merger between the American Le Mans Series and the Rolex Sports Car Series in 2014, and the eleventh under the sponsorship of WeatherTech.
The provisional schedule was released on March 13, 2025, and features 11 rounds. [1] [2] The calendar remains the same as the previous season, but the Battle on the Bricks will revert to a 2 hour, 40 minute race as it was in 2023 while the IMSA Sportscar Weekend event at Road America will be the first in IMSA sports car racing history at the track to run a 6 hour endurance race.
