Funding a sportsbook account with a credit card can cost an extra 50% before the game even starts, and the charge rarely shows up where bettors expect it.
- Most card issuers log a sportsbook deposit as a cash advance, so interest starts the instant the money moves and there is no grace period
- A late-March 2026 Federal Reserve Bank of New York report tied sports betting to rising delinquencies and falling credit scores, with men under 40 hit hardest
- A $20 bet funded by card can carry a $10 fee, the kind of math that helped push DraftKings, FanDuel and others to stop taking cards at all
- Sen. Elizabeth Warren has made the fees a federal matter, leaning first on 11 sportsbooks and then on the card companies themselves
Most people who bet with a credit card assume they are making a purchase. Their bank sees it differently. The moment money moves from a Visa or Mastercard into a betting account, the typical issuer files it as a cash advance, a bucket built for pulling cash from an ATM, and one that carries some of the harshest terms in consumer credit.
That one classification is why a credit card is the most expensive way to fund a bet. It is also quietly reshaping the whole business, as the biggest books and a growing list of states move to shut the option off.
How the Cash Advance Trap Springs
Boston – A regular credit card purchase comes with a grace period. Pay the statement in full and you owe no interest. A cash advance works nothing like that. In a sample of agreements from seven of the largest issuers, every one listed online gambling as a cash advance. That means a separate fee, usually the greater of $10 or three to five percent, interest that begins accruing immediately, a steeper rate than the standard purchase APR, and none of the rewards a normal swipe would earn. Because there is no grace period, that interest compounds from the first day even for someone who pays the statement in full, the opposite of how an ordinary card balance behaves.
The size of it surprises people. A bettor who loads $20 onto a card can pay a $10 fee on that single transaction, and Sen. Elizabeth Warren has argued most Americans are “not prepared to lose an extra 50%” in fees on top of the wager itself. Part of the problem is that almost nobody sees it coming. The federal consumer watchdog found that sportsbooks bury the warning, when they give one at all, and one cardholder told regulators there was nothing at checkout to suggest the deposit would be treated “any differently” from an ordinary purchase.
The scale is not small. The bureau calculated that major issuers charged about $717 million in cash advance fees on $3.6 billion in volume in a single recent year, roughly a dollar in fees for every $19 advanced.
The Damage Shows Up in the Credit Data
The cost is not only the fee. It is what borrowing to bet does over time. A 2024 study from researchers at UCLA and USC found that credit scores slipped in states with legal online betting, driven by rising bankruptcies, debt collections, debt consolidation loans and auto loan delinquencies. The newest work is starker. A Federal Reserve Bank of New York staff report released in late March 2026 linked legalization to higher delinquencies, more bankruptcies and lower average credit scores, with the sharpest harm landing on men under 40, the same group sportsbooks chase hardest in their advertising. The researchers even traced the strain across state lines, finding that delinquencies climbed in neighboring counties where betting had not yet arrived.
A credit card is the accelerant in that story. It lets a losing session continue past the point where a debit card or bank balance would have stopped it, and the cash advance terms make the hole deeper and faster than ordinary spending ever could.
Washington Started Asking Questions
The fees have moved from personal finance columns to the Senate. In February 2026 Warren wrote to 11 sportsbook operators about the cash advance “junk fees,” and FanDuel announced its own credit card ban less than a week later. She then widened the net. On April 30 she pressed the major credit card companies for data, arguing the issuers themselves are partly responsible for the high fees through their partnerships with betting platforms, and set a May 15, 2026 deadline to respond.
That scrutiny, stacked on the research, is the backdrop for an industry-wide retreat from plastic.
What It Means If You Still Want to Use a Card
The dominoes were already falling. DraftKings stopped taking credit cards in August 2025 after a $450,000 fine in Massachusetts, and FanDuel ended card deposits nationwide on March 2, 2026, with the two together making up more than 70% of the US online market. BetMGM and Caesars followed within weeks, and a string of states has banned the practice outright.
So the regulated US market is mostly closed to credit cards now. Where the option survives, at offshore books or in states that have not acted, the cash advance trap is exactly the same, only without the consumer protections a licensed operator carries. The cheap fix is boring: a debit card, a bank transfer or a service like PayPal moves the same money without the cash advance fee or the instant interest. If a card is the only route, one call to the issuer to ask how it codes gambling transactions can save more than any promo will return. For a recreational bettor, the gap between deposit methods can quietly dwarf whatever edge a sign-up offer pretends to hand back.

None of this is an argument that anyone cannot bet. It is a warning that the deposit method can cost more than the bet. Anyone who feels betting is becoming a financial problem can reach the National Problem Gambling Helpline any time at 1-800-GAMBLER.
