For the fifth time in the last six months, US online casino revenue surpassed $1 billion in May. Sports Betting Dime reported that the seven iGaming states produced $1.03 billion in revenue.
The same report said May’s revenue rose 14.7% year over year, and it was up 2.4% from April. Sports Betting Dime also said six of the seven legal online casino states posted year-over-year gains of at least 10%.
Sports Betting Dime said Connecticut was the only exception, with a 4.3% year-over-year increase in May. The outlet also reported that clearing the $1 billion mark first happened in December, and that February was the lone month in the six-month period that did not reach it.
According to Sports Betting Dime, year-over-year revenue growth in May was under $132 million, which it described as the second consecutive month that growth was under that level. The outlet said US iGaming revenue for 2026 through five months was $5.04 billion.
By market, Sports Betting Dime reported that Michigan stayed above 20% year-over-year growth throughout 2026. It said Pennsylvania and New Jersey hovered around 10% to 15% year-over-year growth in recent months.
Sports Betting Dime attributed Michigan’s performance to the addition of Hard Rock Casino and bet365 Casino in the state over the last six months. It added that Hard Rock and bet365 were backed by bonus codes and that the operators outperformed their predecessors, helping Michigan close the gap on Pennsylvania.
Looking ahead, Sports Betting Dime said the US was on pace to surpass $12 billion in revenue for 2026.
