What the market did before September 13, 2026

Boxing and UFC18 bouts. Below is how each fight’s no-vig fair probability moved between its first and latest capture, with timestamps. These are market facts — what the prices did — not picks, not predictions, and no read on who won.

66 snapshots across 56 days (Jul 20 – Sep 13), 1–5 per day. Snapshots, not tick data — a price could move and settle between two captures and only the endpoints would be seen. Latest capture Sep 13, 00:00 UTC. “Fair” = the book’s margin removed; a truer implied chance, not a forecast.

Methodology

  • Source. An archive of combat-sport prices (UFC + boxing) captured from multiple books over time. 66 snapshots across 56 days (Jul 20 – Sep 13), 1–5 per day. Snapshots, not tick data — a price could move and settle between two captures and only the endpoints would be seen.
  • 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 makes no movement claim.
  • What this is not. Not a pick, not a prediction, no read on why a price moved, and no result — this page does not say who won. Prices move for many reasons; it reports only that they did, and when.
