- US online casino revenue surpassed $1 billion in May, a feat accomplished in five of the last six months.
- Online casino revenue continues to rise in the seven states with legal markets.
US online casino revenue reached $1.03 billion in May, extending a streak that has now seen the legal online casino market top $1 billion in five of the last six months.
The total from the seven legal online casino states was up 14.7% year over year and 2.4% from April.
Pennsylvania online casinos led the country in May with $321.1 million in online casino revenue. Michigan followed at $305.8 million, and New Jersey online casinos posted $276.3 million.
Together, those three states continued to account for the vast majority of online casino revenue. Michigan online casinos stood out again on growth, with revenue up 21.6% year over year in May. Through the first five months of 2026, Michigan reached $1.50 billion, up 22.1% from $1.23 billion over the same stretch in 2025.
Michigan’s recent momentum has come in part from the addition of Hard Rock Casino and bet365 Casino over the last six months.
Smaller states also posted strong gains
The growth story was not limited to the largest markets.
Six of the seven legal online casino states posted year-over-year revenue growth of at least 10% in May. Connecticut was the only state below that mark, though it still grew 4.3%. Elsewhere, West Virginia online casino revenue rose 32.1%, Delaware climbed 44.9%, and Rhode Island increased 36.3%.
In raw revenue terms, May totals were:
- Connecticut: $63.9 million
- West Virginia: $39.5 million
- Delaware: $15.1 million
- Rhode Island: $6.6 million
One important detail in the data: Some states report adjusted gross revenue, but the table reflects gross gaming revenue before promotional spend is removed. That means state-to-state comparisons can be useful but not always perfectly apples to apples.
On a growth spurt
Through May, US online casino revenue totaled $5.04 billion, putting the market on pace to surpass $12 billion in 2026.
The takeaway is that regulated online casino markets are continuing to grow in the US, with the biggest states still leading and smaller states gaining ground.
The next question is whether June will make it six billion-dollar months in seven. It will also be worth watching whether Michigan can keep outpacing the other major markets and whether the recent slowdown in growth rates continues. As always, any discussion around gambling expansion should be followed with a focus on responsible gambling play.
