The seven states where you can play online casino games pulled in nearly $900 million—specifically, $898.1 million in gross revenue. That’s a 33.1% jump from the $674.9 million they made in May 2024. Although May was huge, April 2025 wasn’t far behind, as it sat on $868.6 million itself.
And May’s victory wasn’t just one or two big states carrying the team, either. Every single one of them saw their revenue shoot up by at least 26.6%, reaching 113% compared to May of last year. Of course, the usual suspects like Pennsylvania, Michigan, and New Jersey still dominated, bringing in the big bucks of $787.3 million of that total.
In that order came Connecticut, West Virginia, Rhode Island, and Delaware.
Pennsylvania and Michigan take the front seat at iGaming
When it comes to online casino action, Pennsylvania is clearly playing in a league of its own. They brought in $289 million in gross revenue. That’s a 34.9% increase compared to what they got this time last year.
Most of that money, $177.2 million, poured in from online slots. Internet table games added $52.9 million to the pot, while online poker chipped in $2.8 million.
While May was an incredible month, it actually ended up being the state’s second-best ever, just barely missing the $291.6 million record they set in March.
But what’s even a bigger deal is that Pennsylvania remains the only state that has already blasted past the $1 billion mark in online casino revenue so far in 2025.
Coming right behind the Keystone State is Michigan online casinos with $251.5 million in revenue. This stood out to be a 26.6% jump from what they brought in during May of last year.
And BetMGM actually sprinted back to the top spot among all the online casino operators in the state. They brought in $63.3 million, making a great comeback after being in second place just the month before.
But it wasn’t a runaway victory. FanDuel was right on their heels, with $61.9 million.
FanDuel leads the pack in New Jersey
In May, the Garden State’s online slots and tables pulled in $246.8 million. And that’s a 28.5% leap from what they managed in May of last year.
What’s interesting is this is the next best thing after the all-time high they made in March this year with $243.9 million. So, twice in just a few months, they’ve shown they’re only ascending.
Now, who’s actually making it happen? A collection of all the seven operators, but FanDuel Casino is obviously bringing home more of that bag. The operator came in with $54.4 million. DraftKings wasn’t far behind with $48.1 million.
Then you’ve got BetMGM with $32.5 million, and Borgata holding its own at $20.8 million.
Small states, big wins
While the big three often grab the headlines, the other states are putting up some numbers too.
Take Connecticut online casinos, for example. They actually hit a new monthly high in May, with $61.3 million. That’s a 32% jump from last year, and FanDuel even topped $30 million there for the first time.
Over in Delaware, BetRivers pulled in $10.4 million in May, a new record for them. Their year-to-date money has more than doubled compared to last year.
West Virginia nearly doubled its revenue from last year, bringing in $34.3 million in May—a 103.7% increase.
And finally, Rhode Island generated $4.8 million in May, with their total money wagered increasing by over 110% compared to May 2024. Players just went for it, betting about $129.1 million. Out of that, online slots were the main earner, bringing together $3.7 million. And online table games weren’t far behind, generating $1.1 million, up 73.7% year-over-year.
What are tax numbers?
So how much cash did the states actually pocket from all that online casino action in May 2025?
Well, out of $898.1 million in gross revenue, they were able to tax that and pull in $175.1 million for their state budgets.
Now, for comparison, that’s an impressive increase from what they saw in May 2024. Back then, these states collectively took in about $131.6 million in taxes from online casinos. So, we’re talking about an increase of roughly $43.5 million in just one year.
It really shows how much more money is flowing into state coffers as online gaming grows. Just keep in mind, these figures don’t even include any extra local taxes or money that might have gone directly to tribal gaming operations.
