Which Sportsbook Was Closest?
The idea here is simple enough: store what the big sportsbooks were showing shortly before kickoff, then hold those numbers up against what actually happened once the game ended. Each line is taken from a window running 65 to 55 minutes out, and the reading closest to 60 minutes before kickoff becomes the record for that game. Once a record is written it stays as written, so a book that had no usable number in the window keeps a stored missing outcome rather than a number filled in later. None of this is a pick or a recommendation.

America/Chicago. This is the last time we queried the odds provider, which is a separate thing from a stored capture and does not confirm a successful refresh.

How this works
Each line is captured inside a window running from 65 to 55 minutes before kickoff, and the observation closest to 60 minutes before kickoff becomes the record for that game. Once that window closes, the stored number is final.
Later line movement does not change the stored snapshot, and a missing observation is never reconstructed after the fact. If a book had no usable number inside the window, it stays marked Missing.
The counts on this page are not interchangeable. A scheduled game is a game on the stored schedule. Provider event coverage is the subset of those games the odds provider listed at all. Available markets are the spread and total offerings inside a listed event. A game and book slot is one sportsbook for one game, and a game, book, and market slot splits that again by spread and total. An individual selection record is a single priced side, such as one team on the spread or the Over on a total. A game can be scheduled, have no provider coverage, and therefore produce no market and no selection records at all.
The error figures above measure absolute distance from the final margin or the final combined total. Lower means the number was measurably closer to what happened, not that any book is a better predictor going forward. Nothing on this page is a pick, a rating of future performance, or a recommendation to wager.

One time baseline
Launch day baseline batch
This is a one-time launch day baseline batch, captured once at a single moment on August 29, 2026. It is not a T-60 capture and it is not part of the standardized season comparison. Each row shows the exact time the number was observed and how many minutes before kickoff that was. These values are frozen and are never refreshed.
