Use one sportsbook for the Super Bowl market and the best available outcome is being on the right number for half the board. That is the ceiling, not the average. Most books land well short of it.
Five books quote this market across all 32 teams. Run the comparison team by team and the same pattern holds whichever book a reader favours: none of them covers more than half the field, and the gap between the best price and this book's price is not small when it appears.
The coverage numbers
| Book | Teams where it has the best price | Teams where it does not | Average shortfall when behind |
|---|---|---|---|
| BetMGM | 16 | 16 | 24.5% |
| FanDuel | 13 | 19 | 23.1% |
| DraftKings | 12 | 20 | 35.8% |
| Caesars | 9 | 23 | 37.3% |
| bet365 | 8 | 24 | 24.1% |
Four of the five cover fewer than half the board. When a book is off the best number the shortfall averages roughly a quarter of the payout, which is not a rounding error. The tail is worse than the average: the single worst miss runs from 99.2% at FanDuel to 232.6% at Caesars, depending on the team.
A book counts as having the best price whenever it matches the longest number available, so a shared best price counts for every book holding it. These figures are not inflated by any tie-breaking.
The best-covering book on this board still leaves a reader short on half the teams. No book solves this by being the one you use.
What this does and does not mean
This is not a case for opening accounts at all five books.
- Ties are common. On close to half this board more than one book sits level at the best number, so a reader is frequently already on the best price without moving anything. When books tie, and what our own sorting hides covers how often, and why our own counts understate it.
- No book covers more than half the board. Because the coverage is scattered rather than concentrated, a reader cannot decide in advance which book will hold the best number on a given team.
- The averages skew high. Much of the shortfall above comes from the longshot end, where prices scatter far more than they do near the top. Nobody sharpens a number nobody bets explains why. A reader working the top of the board will see smaller gaps than these figures suggest.
Put together, the conclusion is narrower than "shop everywhere" and more useful: a reader often does not need to switch, and cannot know in advance when that is true.
None of this is a case against any book. bet365 covering 8 of 32 is a fact about this board on this date, not a verdict on the book. The same holds up and down the table.
The instruction
Check the number before entering, every time, whatever the default book is. It takes under a minute, and given that coverage moves team by team, that minute is the difference between the number in the table above and the number actually received.
The Forecaster reads every quoted board at once, which is what makes the check quick enough to do every time.
Prices are the boards as of 15 August 2026 across the five books quoting the Super Bowl market. A book is counted as having the best price when it matches the longest available number, so shared best prices count for every book holding them.
