What Are Profit Boosts — and How Do You Use Them?

Profit Boosts (also called “Odds Boosts” or “Profit Boost Tokens”) are promotions that increase your potential winnings on a selected bet by a stated percentage — without requiring a larger stake. They’re one of the most common ongoing promos at every major sportsbook.

Here’s the simple breakdown:

A 100% Profit Boost doubles the profit portion of a winning bet. If your $25 bet would normally win $30, it now wins $60. Your stake is returned as normal.
A 50% Profit Boost increases the profit by 50%. $30 normal profit becomes $45.
An Odds Boost pre-applies an enhanced line. You’ll see it listed as “+300 boosted to +400” in the promotions tab. You just click and bet at the new odds.
Max bet limits always apply. Every profit boost token has a max bet (usually $10–$25). Never assume you can stake unlimited amounts at the boosted rate.

How to use them wisely:

Apply boosts to positive-odds bets (+100 or higher). The boost multiplies a larger profit number, giving you more in absolute dollars.
Avoid applying boosts to heavy favorites (-200, -300). The profit is already small — boosting a small number doesn’t add much value.
Use boosts on bets you would place anyway, not bets you’re taking solely because of the boost.
Check expiry. Most tokens expire within 24–72 hours of issuance. Don’t let them go to waste.

Caesars runs some of the most creative ongoing promos in the market, particularly around NBA and major sporting events. Active offers:

FanPoints Loyalty Program — Every wager earns FanPoints redeemable across the entire Fanatics ecosystem — jerseys, shoes, gear, and sportsbook credits. For sports fans who shop at Fanatics regularly, this is real money back on purchases you’d make anyway.
Reload Bonuses — Fanatics periodically offers deposit match promos for existing users. Keep an eye on your email and the “Promos” tab for reload offers, which typically appear around major sports events.

How to Never Miss a Good Promo

Sportsbook promos are time-sensitive and easy to miss. Here’s how to stay on top of them:

Check the “Promos” tab every time you open the app. All five major books have a dedicated promotions page. Make it a habit to check before placing any bet — there’s often a boost or free bet you can stack on top of your planned wager.
Enable email notifications. Sportsbooks send promo alerts to registered email addresses. DraftKings and FanDuel in particular send daily “Today’s Boosts” emails that serve as a useful promo digest.
Enable push notifications on the app. Most sportsbook apps will push alerts for limited-time boosts (especially around game time). These flash promotions often expire within hours.
Bookmark this page. We update it monthly with the current best offers at each book. Come back at the start of each month — April through summer will bring MLB-specific promos and potentially new welcome offers if the books refresh their deals.
Don’t over-optimize. The goal is to find value, not to spend hours chasing marginal promotions. If a promo aligns with a bet you were already going to place, use it. If you’re only betting because of a promo, that’s the promo working against you.
