Free bets are the most scrutinized offer in sports betting, yet bettors misunderstand which free bet value is real and which is marketing fiction. This guide ranks sportsbooks by actual free bet value, explains the difference between "free bet stake returned" vs. "profit only" promotions, calculates true conversion rates, and identifies which operators offer the highest expected value on free betting.
Sportsbook | Welcome Free Bet | Free Bet Type | Minimum Odds | True Value |
DraftKings | $150 (1st bet) | Stake Returned | -110 | $140-150 |
FanDuel | $150 (1st bet) | Stake Returned | -110 | $140-150 |
BetMGM | $200 (new users) | Profit Only | -110 | $95-105 |
Caesars | $300 (new users) | Profit Only | -110 | $140-160 |
Bet365 | £100 (first bet) | Stake Returned (if lose) | 1.50+ (3/10) | £45-80 |
Free Bet Types: Stake Returned vs. Profit Only
Stake Returned Free Bets (Best): You get both stake and profit if you win. $100 free bet at -110 pays $190.91 if won, $0 if lost. True value approximately $100-150.
Profit Only Free Bets (Standard): You only receive profit; the stake disappears. $200 free bet at -110 pays $181.82 profit only if won, $0 if lost. True value approximately $90-110.
Restricted Odds Free Bets (Worst): Only usable on specific odds (usually -200 or higher). Rarely offered by top sportsbooks today.
Common Restrictions
Minimum Odds Requirements: Some books require -110 or better (1.91+). Bet365 requires 1.50+, eliminating heavy favorites. Bet Type Restrictions: Some free bets can't be used on live betting, parlays, or props. DraftKings allows most bet types; FanDuel restricts some. Expiration Dates: Most free bets expire 7-30 days. Sport Restrictions: Rare, but some books exclude esports or select sports.

Strategies to Maximize Free Bet Value
Use Stake Returned Bets on Lower Odds: A $150 stake-returned free bet at -200 odds has higher expected value than at -110. Bet Immediately After Sign-Up: Use free bets within 24 hours when possible. Fresh sign-ups have better line access. Avoid Parlays Unless Forced: Single bets maximize value. $150 on 1 game at -110 has $95-100 expected value versus $60-70 on 3-game parlay. Stack Free Bets with Deposits: DraftKings offers $150 free + 100% match up to $500. Total real value approximately $350-400.
