America’s commercial casino gaming revenue topped $40b in 2017, with five-sixths of US casino states reporting year-on-year revenue gains.

On Wednesday, the American Gaming Association (AGA) released its annual State of the States report, which showed non-tribal casino gaming revenue hitting $40.3b in 2017, up 3.4% from 2016. State governments’ share of this bounty improved 3.1% to $9.2b.

The number of casinos surveyed fell from 515 in 2016 to 460 last year due to “a rigorous effort to accurately and consistently identify individual gaming properties.” Nevada was responsible for the bulk of the decline under this new metric, with its casino count falling from 273 to 215.

Of the 24 states with commercial casinos, 20 reported year-on-year gaming revenue gains. Twelve states set new revenue records, with the largest increase (34.6%) coming in Maryland, thanks to the late-2016 opening of MGM Resorts’ new National Harbor venue.
