Reading the forecasts
RaceIQ IMSA forecasts the IMSA WeatherTech SportsCar Championship — a win and podium probability for every car, in every class, plus each class’s title fight. It is part of MotorsportVerse, a family of prediction sites built on one shared engine.
Multi-class, always
Endurance racing runs several classes on track at the same time — GTD PRO and GTD this season — and each is its own championship. Every standings table, forecast, and round page is filtered by class using the coloured selector at the top; the colours are the classes’ own.
The unit is a car
An entry is a single car — identified by its number, team and manufacturer, shared by a lineup of drivers. Points, wins and podiums accrue to the car. Each car has its own page with its season results and round-by-round predicted-vs-actual finishes.
What the numbers mean
A win probability is the model’s estimate of a car winning its class; a podium probability, of finishing in the class top three. The predicted classification is the single most likely finishing order — the probabilities describe the spread around it. Projected points show a P10–P90 range for the rest of the season.
Honest scoring
After every round each class forecast is graded against the real result and published on the accuracy page — mean position error, podium hits and exact finishes, with nothing left out. Endurance fields are large, so landing a car within a few places of its prediction is a strong result. Probabilities are calibrated on 9 real rounds of results so far, per class.
Not affiliated, not advice
RaceIQ IMSA is an independent MotorsportVerse project. It is not affiliated with IMSA, IMSA WeatherTech, or any team, and its forecasts are model estimates — not betting advice.
