About The Odds Gap
The Odds Gap is a free line-shopping tool for US sports bettors. Throughout the day, it scans every major sportsbook, plus prediction markets like Kalshi and Novig, for the same bets and shows you who is offering the best price. If two books are paying different odds on the same team, you see it instantly.
That's the whole pitch. There is no model picking winners and no "lock of the day." The site tells you where to bet, once you've decided who to back.
Why it exists
The single most reliable edge in retail sports betting is line shopping. Two bettors who pick the same winners but bet at different books will, over a long enough sample, finish thousands of dollars apart on the same picks. The gap between the best price and the worst price on a popular game can be 10 to 30 cents of juice on the moneyline, or a half-point on the spread.
Almost no one shops their lines. The books know this, and that's why they don't match each other. Every cent of price difference is money that the average bettor leaves on the table.
The Odds Gap exists to fix that. Instead of opening seven sportsbook tabs to find out which one is paying +112 instead of +106 on the team you've already decided to back, you open one.
Who runs it
The Odds Gap is a one-person operation, built by a sports bettor first and a builder second. The Odds Gap is not affiliated with any sportsbook, syndicate, or tout service. The Odds Gap LLC is not a registered investment advisor and nothing on this site is investment, financial, or gambling advice.
The site runs on a small self-funded server. Data comes from a paid odds feed and from public APIs. There is no venture capital behind it and no sponsor steering you toward one book over another.
Some links on the site are affiliate links, and they are labeled as such. The odds comparison is never weighted in favor of a partner. Wherever the best price actually is, that's what The Odds Gap shows you.
What's free
Everything on the site today is free. There is no paywall and no "unlock the +EV plays" gimmick. The free board is an hourly snapshot of every tracked book, shown to anyone who visits, and the Live Beta board, which rescans every minute, is free with an email signup.
A paid tier may come later. If it does, it would be built around faster data for bettors who want to catch line moves sooner, and the math behind every metric would stay identical across tiers.

Responsible gambling
Sports betting is gambling. Most people who do it lose money over the long run, even with good line shopping. If you are betting more than you can afford to lose, betting to chase losses, or hiding your betting from people you live with, please stop and call 1-800-GAMBLER. There is no shame in it.
This site exists to give a slightly better deal to people who have already decided to bet. It is not an endorsement of betting.
