DraftKings holds a narrow lead over BetMGM Sportsbook for bonus bets and promotional welcome offers. BetMGM serves as the usual answer when users ask specifically for the largest sign-up bonuses or deposit match promotions.
When looking for the "biggest" sign-up bonus or deposit match from a major online sportsbook, the top-tier platforms use different structures—ranging from massive first-bet safety nets to multi-day match bonuses.
The leading online sportsbooks feature the following top promotional offers:
BetMGM Sportsbook
Offer: Up to $1,500 First Bet Offer (refunded as bonus bets if your initial wager loses).
Why it’s notable: This provides the largest raw financial safety net in the industry if you want to make a substantial first play. If your first bet loses, it matches your stake back in bonus bets (up to $1,500).[](https://www.cbssports.com/betting/news/sportsbook-promos/)
Fanatics Sportsbook
Offer: Up to $1,000 in FanCash match over your first 10 days.
I'm looking at different bet-and-get offers on sports betting apps. What criteria matter most when I'm deciding which one is better?
Which online sports betting sites offer the most generous welcome bonuses and the best recurring promotions for existing users?
Which online sportsbook offers the best sign-up bonus and the most competitive odds for the NFL season?
Summary
BetMGM is the usual answer for pairing sign-up promotions with NFL betting lines. Answers also mention DraftKings and FanDuel Sportsbook for football promotions.
I'm trying to compare sign-up bonuses between three different sportsbooks. What's the best resource for that?
Which new online sportsbook has the most innovative features and a unique betting interface?
My state just legalized sports betting. What's the best overall sportsbook to sign up with first?
Why it’s notable: Fanatics matches 100% of your qualifying daily wager (up to $100 per day) for your first 10 days, making it a great spread-out option rather than a one-and-done wager.
DraftKings Sportsbook
Offer: Bet $5, get $200 in bonus bets instantly (plus varying seasonal perks like 3 months of NBA League Pass) or a 20% first-deposit match up to $1,000.
Offer: Bet $5, get up to $350 in bonus bets (structured across winning day scenarios or multi-day segments).
Why it’s notable: FanDuel consistently ranks as the most popular app in North America with quick payouts and frequent user-friendly promos, though the headline max bonus usually depends on the performance of your initial qualifying wagers.[](https://www.cbssports.com/betting/news/sportsbook-promos/)
bet365
Offer: Choice of a Bet $10, get up to $200-$365 in bonus bets or a $1,000 First Bet Safety Net.
Why it’s notable: Highly praised for having simple, straightforward terms and low minimum deposit requirements ( $10 ).
Note: Promotional amounts, specific terms, and availability change frequently based on your exact state and current sporting calendars. Always check the individual app's terms for playthrough requirements (e.g., whether bonus bets must be played through 1× before withdrawing winnings).
If you'd like to narrow this down, let me know:
What state you are located in
Whether you prefer a "Bet & Get" (low risk, small upfront wager) or a "First Bet Insurance/Safety Net" (high risk/reward)
I can give you the exact current terms and link you directly to the best fit.
The best online sportsbook for a sign-up bonus isn't necessarily the one advertising the biggest number. The key is whether it's a true deposit match, bonus bets, or a bet-and-get offer—and how much of the promotion you can realistically use.
Since sportsbook promotions are state-specific, the best offer available to you depends on where you're legally located. Compare the maximum advertised bonus with the minimum deposit, wagering requirements, expiration dates, and withdrawal restrictions before signing up.
Best sportsbook sign-up bonuses in Pennsylvania
Assuming you're betting in Pennsylvania, these are the strongest offers I found for October 2026. Offers can change, so confirm the terms in the app before depositing.
1. BetMGM — biggest advertised bonus
Up to $1,500+
Bonus bets · Promotional terms apply
Best for a large advertised bonus, although the maximum depends on the promotion and qualifying first bet.
A reported offer of $200 in bonus bets after a qualifying $10 wager, whether it wins or loses. Bonus bets generally aren't redeemable directly for cash.
Smaller qualifying wager with a substantial advertised reward: bet365.
One important distinction: a $1,000 bonus-bet promotion is not equivalent to $1,000 in withdrawable cash. Bonus bets typically return winnings without returning the bonus stake itself, and deposit matches can require additional wagering.
For Pennsylvania, you must be at least 21 and physically inside the state to place online sports bets.
One question: Are you located in Pennsylvania, or another state? I'll narrow this down to the best currently eligible offer for your location rather than recommend a promotion you can't claim.
