Signup Bonus Bets Explained
A signup bonus bet (or welcome bonus bet) is a promotional free bet given to new customers when they register at a sportsbook. Some require a qualifying deposit or first bet, while rare offers give a small free bet just for creating an account.
Unlike deposit matches, bonus bets typically return only the profit (not the stake) if they win. So a $100 bonus bet at +150 returns $150 profit, not $250 total.
How to Maximize Signup Bonus Bets
Strategic tips for getting the most from signup bonus bets:
- Use them on underdogs — Since you only keep the profit (not the stake), longer odds maximize your return. A $100 bonus bet on a +300 underdog returns $300 if it wins.
- Don't waste on heavy favorites — A $100 bonus bet on a -300 favorite only returns $33 profit.
- Look for +EV spots — Use Knockout Odds to find the best odds across books, then place your bonus bet where you have the most edge.
- Check expiration — Most bonus bets expire in 7-14 days. Don't let them go to waste.
Bonus Bets vs Cash Bets
Key differences between bonus bets and cash:
| | Cash Bet | Bonus Bet |
|---|---|---|
| Stake returned on win | Yes | No |
| Can be withdrawn | Yes | After wagering |
| Optimal strategy | Bet normally | Bet on plus-money (underdogs) |
| Typical value | Face value | ~70% of face value |
Frequently Asked Questions
Do I get the stake back on a bonus bet?
No. With most sportsbook bonus bets, you only receive the profit from a winning bet, not the original stake. A $100 bonus bet at +200 returns $200 profit (not $300).
Can I split a bonus bet into smaller bets?
It depends on the sportsbook. Some allow you to split (e.g., five $20 bets from a $100 bonus), while others require you to use the full amount on a single bet. Check the terms.
