Entries for the 2026 IMSA WeatherTech SportsCar Championship have opened following the Motul SportsCar Grand Prix at Road America.
Teams wishing to contest the full season, the Michelin Endurance Cup, or in individual events may do so from now until Tuesday, 7 October, or until the list of entries fills up. The deadline to confirm driver combinations and events will be on Tuesday, 2 December.
And the list of prospective entries is expected to fill quickly during a period in which many IMSA events are running at or near capacity grid size. Major events, including the Rolex 24 At Daytona, have had to implement reserve lists in recent years, with more prospective entries than garage spaces available.
“The enthusiasm surrounding the IMSA WeatherTech SportsCar Championship continues to grow, and we’re once again expecting more entry applications than we can accommodate,” said IMSA President John Doonan. “It’s a testament to the strength of our platform and the commitment of our teams, manufacturers, and partners. As we open entries for 2026, we remain focused on delivering a competitive and compelling championship for all stakeholders and especially IMSA race fans.”
