Best sportsbook bonuses, ranked by real value

Sportsbooks advertise huge numbers — but the headline isn't what you get. We rank every major sign‑up offer by what it's actually worth after the fine print: bonus bets aren't cash, and "first bet back" offers only pay if you lose.

Case in point: BetMGM's headline $1,500 offer is really worth about $36.

How we value an offer

Frequently asked questions

Why isn't the biggest bonus the best?

Because the headline number isn't what you get. A "first bet up to $1,500 back" only pays if you bet big and lose, and even then it's bonus bets, not cash — so its real value to a normal bettor is a small fraction of the billboard figure. A guaranteed "$5 gets $365 in bonus bets" is worth far more.

What is a bonus bet actually worth?

About 70 cents on the dollar. When a bonus bet wins you keep the winnings but not the stake, so a $100 bonus bet is worth roughly $70 in real terms — never face value.
