IMSA WeatherTech is an endurance sportscar championship running GTP hybrid prototypes, GT3 cars in professional and amateur classes, and LMP2 prototypes. The field is established professional calibre, anchored by drivers such as Alex Palou, Pascal Wehrlein and Scott McLaughlin; the professional classes GTP and GTDPRO field predominantly Platinum and Gold-graded drivers, while the amateur-focused GTD class is predominantly Silver and Bronze. The series draws drivers up from single-seater feeder categories and serves as a destination for established professionals seeking sustained endurance racing rather than a stepping stone onward. Its multi-class structure separates professionals and amateurs into distinct categories, allowing competitive racing at both levels within the same championship. Drivers who move on typically step down to smaller-grid amateur or regional endurance series rather than graduating to higher categories.
