Exchange Sign-Up Offers, with the Best Value at Each
Each card below is one exchange's current sign-up offer, the code that unlocks it, and up to 3 lines on the board right now where that exchange is paying the best price. The lines are measured, not chosen: they refresh every five minutes from the same scan the Line Shop reads.
Disclosure: BetMGM, ProphetX, Kalshi, Novig and Polymarket US are affiliate partners of The Odds Gap. The measurements on this page are computed from scanned prices and are never weighted toward a partner. Where a partner ranks is where the prices put it. Privacy & Disclosure.

Best-value lines compare the exchange against every regulated sportsbook and exchange on the board at the same line; offshore books are left out. Gap is the difference in implied probability between the exchange's price and the next-best book, the same number the Line Shop shows. Always verify the price at the exchange before you trade. How the site computes every number is on the Methodology page.
