Since June 3, 2026: 5 games from 21 books. Last game added June 13, 2026.

This NBA sample is still small: 5 finished games so far. It grows with every game we scan as the season goes.

What's in It

  1. Moneyline, spread and total for every NBA game we scanned.
  2. Each book's earliest price and closing price at every line.
  3. The line movement between them, in probability points.
  4. Pinnacle as the sharp reference, never counted as the best price.
  5. Player props at four checkpoints, where books post them.
  6. A free sample week, recent and full history by subscription.

Questions

Where can I download NBA historical odds as a CSV?

Right here. A sample week, September 15 to 21, 2026, downloads free with no key. Recent data and the full NBA history back to June 3, 2026 are a subscription. Every file also comes as JSON or Parquet with the same rows and columns.

Does this include NBA opening and closing lines?

Closing lines, yes: each book's last price before the game started. For the open, you get the earliest price we captured at that line, which is not always the market's first posted line, and the file labels it that way.

How far back does the NBA data go?

To June 3, 2026. Our coverage starts on June 4, 2026 across every sport, so this is not a multi-season archive. It grows with every NBA game we scan.
