Host Nation Edge
🇺🇸 USA · Group D
vs Paraguay, Australia, Türkiye · SoFi, MetLife, AT&T. Model boosts λ ×1.15 for home crowd.
🇲🇽 Mexico · Group A
vs S.Africa, S.Korea, Czech Rep. · Opens at Estadio Azteca June 11. Massive home support.
🇨🇦 Canada · Group B
vs Bosnia, Qatar, Switzerland · Games in Toronto + Vancouver. 2nd ever WC appearance.
Model
Dixon-Coles Monte Carlo — 10,000 full tournament simulations. Each of the 104 matches is simulated using ELO-derived expected goals with bivariate Poisson + low-score (tau) correction.
Host advantage baked into expected goals (×1.15 scoring multiplier for USA/Mexico/Canada home games).
Knockout resolution: 90 min → extra time (⅓ scoring rate) → penalties (slight ELO edge).
Edge calculation: model win% minus de-vigged market probability (raw implied normalized to 100%).

Key Injury Watch
DUKE — CALEB FOSTER
Guard injury — status uncertain. Model reduces Duke win prob by 3% if out
MICHIGAN — L.J. CASON
Guard injury looms large — Wolverines depth tested in tournament
GONZAGA — BRADEN HUFF
Out first two rounds — Zags offense significantly diminished without him
Model Methodology
Features: KenPom efficiency, seed, SOS, recent form, injury adjustments, bracket path difficulty. Edge = model win prob vs sportsbook implied prob. PLAY threshold: edge > 3% + Kelly > 0.3%. Tournament in progress — model updates after each round.

How It Works
1 · DATA INGEST
OpenF1 API (live telemetry, pit stops, positions at 3.7Hz), FastF1 Python library (lap times, tyre data, 2018–2026), Ergast API (historical results back to 2020), Betfair Exchange (live odds and implied probabilities), OpenWeather (race-day forecasts).
2 · FEATURE ENGINEERING
Rolling 5-race form, qualifying pace delta from pole, circuit-specific career stats, constructor reliability scores, tyre strategy history, safety car probability, and regulation-year weighting adjustments for 2026.
3 · MODEL
LightGBM classifier trained on 2020–2025 data. Separate models for win, podium, top-6 and top-10. Calibrated with Platt scaling for accurate probabilities. Retrained every Thursday after qualifying data is in.
4 · EDGE CALCULATION + SIGNAL
Model probability minus vig-adjusted bookmaker implied probability. PLAY signal when edge exceeds 5% and Kelly fraction is positive. FADE when book is materially overpriced. All signals published with explicit edge % and expected value.
