BUILDING THE NEXT GREAT
SPORTS BETTING MODEL
In public, loss by loss. An open football model from PolarBearQuant covering the pros and college — every line published before kickoff, every result graded against the closing line. No guru picks, no deleted losers. The market is still ahead. Watching the model chase it is the point.
How This Site Works
This model does not beat the closing line yet, and the site says so on every page. What it offers instead is a standard: transparent, rigorous, open.
Transparent
Every prediction is timestamped before kickoff and graded against the closing line afterward — losses included. Nothing gets deleted, nothing gets cherry-picked.
Rigorous
Walk-forward backtests with no lookahead. Tuning seasons never touch evaluation seasons, so the numbers you see are the numbers the model actually earned.
Open
The methodology is public, down to the version history. Rejected model versions are documented alongside the one that shipped, so you can see what didn't work and why.

See the Board, Judge for Yourself
Every game, every model line, every assumed starter — published before kickoff and graded against the close after. If a model seller won't show you that, ask why.
