Iowa casinos heading for record revenues. Sports betting handle tops $1 billion Rod Boshart, Gazette Des Moines Bureau · June 11, 2021 at 2:27 pm Iowa casinos are on track to have their most-profitable year ever, with officials crediting “pent-up” post-pandemic demand among Iowans eager to spend money at entertainment venues as a key factor in the fiscal 2021 revenue surge. Also, while sports betting slowed somewhat in May, the month’s wagering handle still came in at nearly $114.9 million. It was enough to push year-to-date gambling action in Iowa above $1.1 billion, with another month until the books close June 30, according to numbers issued Thursday by the state Racing and Gaming Commission. Overall, Iowa’s 19 state-licensed casinos posted adjusted gross revenue of nearly $1.434 billion through May — an 11-month figure that topped last year’s figures by about 36%. Casinos were shuttered for 11 weeks early in the pandemic during fiscal year 2020.
