MS HB4074

Creates the Mississippi Mobile Sports Wagering Act, legalizing online sports betting and race book wagering through licensed platforms operating on behalf of existing casinos.

Requires platforms to obtain a manufacturer's and distributor's license from the Mississippi Gaming Commission, with each licensed casino allowed to contract with up to two sports pool platforms and two race book platforms.

Imposes a 22% tax on gross revenue from online sports wagering and race books, with proceeds going to the Mobile Sports Wagering Tax Fund; the first $6 million annually through June 2030 supports a Retail Sports Wagering Protection Fund for non-platform casinos.

Restricts wagering to persons aged 21 and older located in Mississippi, with mandatory geofencing, age verification, and a $250 monthly wagering limit for patrons ages 18-25 unless they demonstrate income above the state median.

Requires platforms to implement responsible gaming programs using AI or algorithmic monitoring to detect at-risk behavior, including mandatory cooling-off periods and intervention protocols for problem gamblers.
