Where to Download Historical NFL Betting Odds

You can download historical NFL odds from The Odds Gap's data page as CSV, JSON or Parquet. The history starts June 4, 2026, covers US sportsbooks and prediction markets, and a sample week, September 15 to 21, 2026, is free with no signup.

1. Every book's price at every scan, or each book's first and last price per game.
2. One row per game and side in the Game Summary file, with the open, close and result.
3. One game_id on every file, so they join with no name matching.
