On September 22, Michigan Senator Veronica Klinefelt proposed Senate Bill 511 which would allow for social wagering contests throughout the state, although any transactions completed at land-based sportsbooks and other gambling establishments would be prohibited according to the bill.
SB 511 would amend the Michigan Penal Code to authorize social wagering contests such as betting pools and sports squares as well as legalize wagering transactions which are "incidental to a bona fide social relationship."
According to the legislation, "no other money or thing of value" can be included in the contests besides the initial individual wager amounts. SB 511 would also allow for social wagering pools or contests with a maximum of 100 participants and individual wagers of up to $25 if approved by the state, having been referred to the Committee on Regulatory Affairs for further consideration.
Throughout September 2025, iGaming and sports betting operators reported $51.6m in state taxes and payments made to the MGCB, while Tribal operators submitted an additional $6.1m to its respective governing bodies.
At the time of writing, 15 commercial and Tribal operators have been authorized by the MGCB to offer iGaming and/or mobile sports betting to residents.
MGCB Executive Director Henry Williams issued an official memorandum to all operators currently licensed to conduct business in the state on October 3 of becoming involved with prediction markets operations and the trading of sporting event contracts
