Iowa’s commercial casinos generated $152.1 million in revenue in May, a 1.8% year-over-year increase, according to figures reported from the Iowa Racing and Gaming Commission.
The May result shows continued stability for the Midwestern casino market, with slot machines accounting for the bulk of statewide revenue. CDC Gaming reported that slot revenue reached $138.4 million, up 2% from the prior year, while table games revenue slipped 0.6% to $13.8 million.
The figures cover Iowa’s 19 licensed casinos and show a mixed but broadly positive month across the state. Eleven properties posted year-over-year gains, including Prairie Meadows, the state’s largest revenue generator. Prairie Meadows recorded $22 million in May revenue, up 2% from the same month a year earlier.
Several other Iowa casinos produced double-digit revenue totals during the month. Horseshoe Casino Council Bluffs generated $14.4 million, Ameristar II reported $14 million, and Riverside Casino reached $10.7 million. Those figures underline the continued concentration of gaming revenue among the state’s larger properties, even as smaller venues also contributed to the market’s overall increase.
The strongest year-over-year growth came from Bally’s Marquette, which opened as a land-based casino in March. CDC Gaming reported that the property posted a 77.7% increase to $3.2 million, reflecting the impact of its move into a new format. Grand Falls Casino and Isle of Capri Bettendorf also recorded notable increases, rising 16.1% and 15.4%, respectively.
Not every property moved higher. Rhythm City Casino saw the largest year-over-year decline, falling 8.3% to $9.3 million. Great River Casino was down 6.8%, while Horseshoe Casino Council Bluffs declined 6.5% despite remaining one of the state’s higher-revenue properties by total amount.
For the US casino sector, Iowa’s May figures offer a useful snapshot of regional gaming demand outside the largest destination markets. The state’s performance also shows how property-level changes, such as Bally’s Marquette’s land-based opening, can affect year-over-year comparisons in mature casino jurisdictions.
The results come as US casino operators and regulators continue to track regional gaming trends, slot performance and table game softness across individual states.

State revenue reports are closely watched because they can show whether consumer demand is broadening or concentrating at a small number of venues. In Iowa, the May figures suggest the slot floor remained the principal driver of growth, while table games were slightly weaker compared with the prior-year period.
The month also highlights how individual property changes can move local comparisons. Bally’s Marquette’s transition to a land-based casino created a much larger percentage gain than the statewide average, while several established casinos saw modest declines despite the market-wide increase.
