US Sportsbook Bonuses & Welcome Offers 2026: Best Promos & Bonus Bets

Welcome bonuses have become the main way US sportsbooks compete for new players. Some offer “Bet & Get” deals, others insure your first wager, and a few reward you with bonus bets even if your first selection loses. The list below prepared by agamble.com pulls verified betting offers and explains how each one works in practical, real-world terms — including how to claim them, wagering rules, and how to use the promo in the smartest way possible.

Online sportsbooks treat bonus bets differently from cash. Bonus bets don’t return the stake, so a $50 bonus bet on +200 only pays $100 profit, not $150. That’s why many players use these offers on plus-money selections or parlay legs with higher upside.

Below is a clear table of all available US sportsbook bonuses for 2026.

US Sportsbook Bonuses (2026)

How to Claim The Best US Sportsbook Welcome Offers (Step-by-Step)

The signup flow is nearly identical across all US sportsbooks. Here’s a real-world process that applies to Bet365, FanDuel, Caesars, BetMGM, and most others:

1. Register with accurate personal details
   Sportsbook apps verify your identity via SSN and geolocation. Mismatches delay payouts and bonuses.
2. Enter your promo code at signup. Bet365 uses USB365.
3. Make a qualifying deposit
   Minimum deposits usually range from $5–$10.
   Avoid PayPal or prepaid cards if the sportsbook excludes them — some bonuses require debit cards or ACH.
4. Place the qualifying wager
   • Bet365 requires $5
   • Bally Bet requires $50
   • BetRivers allows any wager but refunds losses up to your limit
5. Receive bonus bets automatically
   Some bonuses settle instantly (Bet365), while others trigger only after the first bet wins (FanDuel, DraftKings).

How to Use Bonus Bets the Smart Way

Bonus bets do not return your stake. Because of that, the value is highest on:

✔ Plus-money odds

A $50 bonus bet at +300 returns $150 profit; at –150 it returns only $33.

✔ Straight wagers or two-leg parlays

Avoid large parlays. Bonus bets are not meant for 10-leg lottery tickets unless that’s your preferred style.

✔ Markets with transparent probabilities

NFL spreads, NBA totals, and UFC moneylines give you consistent returns.

✔ Hedge opportunities

Some bettors place the bonus bet on the opposite side of an existing wager to guarantee partial value.

Bet365 — Bet $5, Get $150

If you place a $5 wager on the Detroit Lions +3 and they lose, you still get $150 in bonus bets.
That’s why this welcome offer is considered one of the most “new-player friendly” in the US market.

Fanatics Sportsbook — Up to $2,000 FanCash

FanCash works like store credit:

• 1 FanCash = $1 toward bonus bets
• You can redeem FanCash for new wagers at any time

This gives players flexible value rather than forced wagers.

BetRivers Second Chance Bet ($100–$500)

If you bet $200 on the Lakers ML and lose, BetRivers refunds all $200 in bonus bets.
The promotional bet credits can be split into smaller wagers, which many sports betting players in the USA prefer.

Caesars Sportsbook — $1,000 First Bet on Caesars

If your $1,000 wager loses, the online sportsbook returns the full stake as bonus bets, usually divided into 5–10 smaller credits.

What is the difference between a bonus bet and a deposit match?

Bonus bets must be wagered; they don’t return the stake.
Deposit matches (usually in casinos) must meet wagering requirements.

Do US sportsbooks require promo codes?

Some do (Bet365: USB365) while others auto-apply the welcome offer. Missing a promo code may prevent you from receiving the full bonus.

Can bonus bets be withdrawn?

No. Only the profit from bonus bets is withdrawable.
