Affiliate disclosure: OddsShopper may earn a commission when you sign up at a sportsbook through our links. That never changes which offers we list — a promo only appears here after we confirm its terms are current and its link works.
This page refreshes weekly (week of July 19, 2026, 2026-W29), and every offer below is checked before it appears: if an operator's terms or sign-up link can't be verified, it is left off — you will never find a dead offer here. The list covers traditional sportsbooks plus regulated betting exchanges and prediction markets. Live right now: Caesars Sportsbook, Fanatics Sportsbook, Novig, ProphetX, Polymarket, Onyx Odds.

A sign-up bonus is only half the edge — the other half is taking the best price every time you bet. OddsShopper compares 20+ sportsbooks and exchanges on every line, then flags the +EV plays for you, so the bankroll a promo hands you goes further. Try OS Pro free for 7 days, and code PROMOEV20 takes 20% off your first payment: Start your free trial.
Every book on this list clears two checks the moment this page rebuilds: the offer terms are the current ones straight from the operator or our own partner page (never an old headline), and the sign-up link is confirmed to still carry our tracking through to the book. Anything that fails either check is dropped, not guessed at. For the framework behind judging any promo by its real value — not its font size — read our guide to the best sportsbook promos, and price your first bet across every book on the free OddsShopper odds screen.
You must be of legal betting age (21+ in most states, 18+ in some) and physically located where the book is legal; individual operators set their own minimums, and sweepstakes social sportsbooks differ from real-money books. Offers can change — the sign-up flow is the final word for your state. Gambling problem? Call 1-800-GAMBLER.
