How we measure it
A book's cut on a market is how far its prices add up past 100%. Each price implies a win chance (1 divided by the decimal odds); on a fair market the chances of every side add up to exactly 100%. At -110 on both sides they add up to 104.76%, so the book keeps 4.76% of what's bet on that market, on average, whichever side wins. The lower the cut, the more of every dollar comes back.
Converge reads every listed book's prices on every game it covers, all day. For each book we take its main line on each game's moneyline, spread and total: the moneyline as it's offered, and for spreads and totals the pair of sides priced closest to even, since alternate lines carry a bigger cut and only some books post them. Each book's game and market counts once a day, at the first price we see that day. A book's overall figure weights each sport's market by how many games all books were measured on in it, so every book is scored on the same mix. A book we measured on fewer sports or markets than the rest is compared with the other books on the ones it has, and that difference is carried over to the full mix; the tables say which ones.
Player props and futures aren't included. The numbers are averages over many games: a single game at any book can be priced better or worse. Check any market's cut yourself.
