Our method
  • We simulate the final margin 40,000 times from our team ratings (margin-aware Elo, fitted on nflverse 2015–2025) and the injury report.
  • The win chance is the share of those simulations each team wins.
  • When the market has a price (Polymarket), it gets 85% of the say and our ratings the rest: over the last ten seasons that mix picked 66.8% of games right, more than either alone.
  • Model nfl-v1.2.0, updated Oct 9.
