Every priced outcome of every game is one selection. "Market said" is the bookmakers' average implied probability with the margin removed; "Happened" is how often that outcome came in. On the diagonal the market was right on average; above it, that kind of result happened more often than the prices said. Bands with fewer than 30 selections are left out.
Home, away
| Outcome | Market said | Happened | Diff |
|---|---|---|---|
| Home win | 52.2% | 63.1% | +10.9 pts |
| Away win | 47.8% | 36.9% | -10.9 pts |
The market's average closing chance for each outcome over all 1,741 games against the share of games it won. "Home" is the first-named side.
Bookmaker accuracy
lower is better| Bookmaker | Games | Brier score | vs market average | Payout |
|---|---|---|---|---|

Each bookmaker's own closing prices, margin removed, scored against the results of the games it priced; "vs market average" compares it with the bookmakers' average on the same games, so a negative figure means its prices were the closer. Bookmakers with fewer than 50 priced games are left out. Differences of a few thousandths are noise; a much higher score usually means the bookmaker's last price was captured well before the start, so it is the price in our archive being scored, not the trader.
