Fight Week: what the market did before Saturday

The Jul 25–26 slate — UFC Abu Dhabi and the Spence–Tszyu weekend. Below is how each fight’s no-vig fair probability has moved, day by day, with timestamps. These are market facts — what the prices did — not picks, and not a prediction of who wins.

Tracking since Jul 20 · daily snapshots (≈08:00 UTC), not tick data · latest sweep Jul 22, 08:00 UTC. “Fair” = the book’s margin removed; a truer implied chance, not a forecast.

Methodology

  • Source. A daily archive of combat-sport prices (UFC + boxing), swept once each morning (≈08:00 UTC) since Jul 20. Daily snapshots, not tick data — a price could move and settle between two sweeps and we would only see the endpoints.
  • Fair probability. Each book’s two-sided price has its margin removed (no-vig), then averaged across books in probability space — never by averaging the American prices. A movement figure needs a complete two-sided price at both captures; single-sided markets show the price only.
  • Movement. The change in that fair probability between a side’s first and latest capture, in percentage points. A bout with one capture bucket makes no movement claim.
  • What this is not. Not a pick, not a prediction, and no read on why a price moved. Prices move for many reasons; this page reports only that they did, and when.
