RaceModel
Read full descriptionHide full description
RaceModel is the race prediction engine that shows its receipts. Before every race our machine-learning model publishes the full predicted finishing order, podium probabilities and DNF risk for Formula 1, NASCAR Cup and IndyCar. Every prediction is locked before lights-out and scored against the official result. Nothing is edited in hindsight: every hit and every miss stays on the record. WHY RACEMODEL IS DIFFERENT - Verified accuracy: a public race-by-race ledger of model performance, 100+ races scored out-of-sample. We show you when we were wrong. - Three racing series in one app: Formula 1, NASCAR Cup and IndyCar. - Built for analysts, not just fans: you get the numbers behind every pick, calibrated probabilities, per-driver confidence and post-race breakdowns. WHAT YOU GET - Full-grid predicted finishing order with confidence per driver - Podium, points and DNF probabilities, calibrated: 70% means 70% - Post-race model retrospective: predicted vs actual, position by position, which drivers beat the model and why - Race strategy analytics: predicted vs actual pit strategy per team, circuit context, tyre stress and recommended strategies - Market analytics: compare the model's probabilities with public prediction-market prices and see where they disagree. Informational only: RaceModel places no wagers and is not a betting operator. - Championship standings, race calendar, per-session weather, circuit data - Model accuracy history across every retrain: the full audit trail ALSO ON THE WEB The same model powers racemodel.io: deeper dashboards, Model Studio for building your own prediction configurations, shareable charts and embeddable widgets. One account works everywhere; web subscribers simply sign in. Free to use, no account needed. The full predicted grid opens after each race; racemodel.io subscribers see it before lights-out. RaceModel is an independent product. It is not affiliated with, endorsed by or associated with Formula 1, NASCAR, IndyCar or any racing team.
