When books tie, and what our own sorting hides

Miami to win the AFC is priced at +15000 at all six books that quote that market. Not close. Not off by a tick. Identical, every one.

Our board still credits exactly one of them with "the best price" on that line, because the board has to pick something. That credit is alphabetical accident dressed as analysis.

It is not a one-off. Across the futures board a large share of what we call the best price is shared by more than one book, and something has to break the tie. What breaks it is not sharpness or aggression in pricing. It is the order the books sit in our table.

How the tie breaks, and how often

Our internal book order is fixed: bet365, BetMGM, DraftKings, Caesars, FanDuel, BetRivers. When two or more books quote the identical number, the sort credits whichever appears first. Leftmost wins, silently, every time.

So a book that sorts early wins ties it did nothing to earn, and a book that sorts late can never win one, however sharp its number.

Every one of those shared prices still resolves to a single credited book.

What that does to each book's record

Set each book's credited wins against the prices it actually held alone:

• bet365 sorts first: credited 15 times, alone 3. Around 80% of its record is the tie-break.
• BetMGM sorts second: credited 51, alone 25. About half.
• Caesars sorts fourth: credited 22, alone 17. Roughly a quarter.
• DraftKings sorts third: credited 40, alone 35. About an eighth.
• FanDuel sorts fifth: credited 26, alone 26. None.
• BetRivers sorts sixth: credited 6, alone 6. None.

FanDuel and BetRivers have never won a tie in any market. They cannot. They sort last.

That is not a knock on either book. It says nothing about their pricing, their limits or their traders. It is entirely a property of where their name falls in a list.

Re-rank by prices held alone and the order moves. On the Super Bowl market bet365 looks second-strongest by credited count; corrected, it is last, with one. On playoffs BetMGM looks second; corrected it is last with three, and FanDuel wins outright with twelve. On division FanDuel looks third; corrected it is first, with seven, none of them off a tie.

The credited count is not meaningless. It is measuring two things at once, genuine pricing edge and sort order, and it does not say which one produced any given number.

What to do with it

The instinct this should not produce is "go find the one true best book." That is what the uncorrected board encourages, and on a meaningful share of the board it is simply wrong.

1. Note how often the market ties. Super Bowl and conference run high, division and playoffs lower, win totals rarely.
2. Where a price is shared, treat every book at that number as equally correct, not just the credited one.
3. If an account is already open at one of the tied books, use it. Opening a new one to capture a price that is not actually better is effort spent for nothing.
4. Save that effort for prices genuinely alone at the top. The Forecaster is where to find them.

What survives the correction

The best price still rotates by market. No single book sits on top everywhere, tie-break or not, and that rotation is real: it is why checking more than one board is worth the minute it takes, as Where the Super Bowl board is widest and Every board sums past one hundred both show from different angles.

What does not survive is the stronger claim that a reader needs an account everywhere to get the best number. Part of that was our sort order talking.

A number wrong in a known direction is more useful than one wrong in an unknown direction. Naming this does not fix the sort. It means the shape of the error is no longer hidden, which is the standard we hold the books to, and it seemed right to hold our own counts to it as well.
