Bonus bets pay profit only — the stake does not come back. That single rule changes the math on every parlay you build with site credit, and a lot of bettors find out the hard way.

What does "profit only" actually mean on a parlay?

Here's the scenario. You get a $100 bonus bet, slap it on a two-leg parlay priced at +100, and it wins. Your account goes up $100 — not $200. The $100 stake was bonus credit; it evaporates the moment the ticket settles. With real cash, that same winning bet would return $200 total ($100 profit plus your $100 back).

The gap matters more as the parlay odds grow. A $100 bonus bet on a long-shot three-legger at +600 nets $600 in profit, same as cash. But a cash bettor walking away with $700 total is in a meaningfully different spot. Keep that difference in mind when you're deciding which ticket deserves real money versus credit.

Do bonus bets need to be played through before you withdraw?

Per standard sportsbook terms, bonus bets must be played through once before winnings can be withdrawn. That's a relatively low bar — one winning parlay clears it — but the clock is tight. Many bonus bet tokens expire within 24 hours of being credited to your account, so don't let them sit.

Should you use a bonus bet on a short parlay or a long one?

Short answer: lean toward a longer-odds ticket. Because you're not getting the stake back regardless, the bonus bet's effective value is entirely in the profit. Parking $100 in bonus credit on a -110 single or a short parlay that pays +130 caps your upside. Stretching to a +400 or +600 parlay — assuming your legs are reasonably researched — extracts more from the free equity. Our guide on how many legs to put in a parlay covers the trade-off between upside and the compounding house edge in more detail.

That said, chasing big odds with bonus bets just to juice the payout is how you waste them. Pick two or three legs you'd actually back with cash, price the parlay, and then decide if the credit fits. Don't reverse-engineer the legs from a target payout.

How bonus bets interact with parlay promos

Two common promotions interact directly with bonus bets — and both have exclusions worth knowing.

Parlay odds boosts typically exclude bets placed with bonus funds. So if you're sitting on a bonus bet and a juicy boost is running, you usually can't combine them. Read the fine print; the parlay odds boost explainer breaks down what those exclusions look like in practice.

Parlay insurance works similarly — bets placed with bonus credit are generally ineligible for the stake-back if one leg misses. The parlay insurance promo guide has the full breakdown of eligibility rules, including the -200 or better requirement per leg.

Bottom line: save your bonus bets for clean, cash-style tickets. Stack them with a boost or insurance promo and you'll likely hit an exclusion clause.

Where to find the best bonus bet opportunities right now

Licensed US sportsbooks — DraftKings, FanDuel, BetMGM, bet365, Caesars, and PointsBet among them — all run bonus bet offers at various points, especially around major sports calendars. Availability varies by state; online and mobile wagering is legal in 30 states as of mid-2025, so confirm your state is covered before signing up. Our best parlay promos page tracks current offers at licensed books. You can also check the parlay house edge math page to understand why even a great promo doesn't fully offset the book's built-in margin on multi-leg tickets.

One more thing: parlay winnings — including those from a bonus-bet-funded ticket — are taxable income. The IRS doesn't care whether your stake was real money or site credit. If you clear $600 or more in net winnings, expect a W-2G form from the sportsbook. Plan accordingly.
