Michigan Regulator Boosts Oversight After NBA Betting Scandal
The Michigan Gaming Control Board (MGCB) is reaffirming its commitment to protecting sports betting integrity following federal indictments that implicated current and former NBA players and coaches. Federal authorities linked the scandal to organized crime and alleged the misuse of confidential player information and the manipulation of proposition wagers (prop bets).

Four Pillars of Michigan’s Integrity Framework
The MGCB highlighted its established regulatory structure, built on mandatory safeguards designed to enforce accountability and consumer protection for legal sports betting.
1. Mandatory Integrity Monitoring
All licensed sports betting operators in Michigan must participate in an integrity monitoring program. The central goal of this program is to identify and report unusual or suspicious betting patterns that suggest insider activity or manipulation.
2. Review and Approval of Wager Types
The MGCB reserves the right to review and approve all events and types of wagers offered by operators. The MGCB prohibits certain wager types that are considered objectionable or easily manipulated. For instance, bets focused on officiating decisions are already banned under state standards due to their high vulnerability to manipulation.
3. Prohibition on Insider Betting
Michigan law explicitly makes manipulating the outcome of a sporting event or using nonpublic information to wager a criminal offense. Operators are required to maintain strict controls to prevent wagering by individuals associated with an event. This includes players, coaches, officials, or anyone with access to confidential information.
4. Internal Control Requirements
Operators must maintain comprehensive internal controls as a mandatory safeguard. These systems are specifically designed to detect and prevent instances of fraud and misconduct within the licensed betting environment.
Prop Bets Under Heightened Scrutiny
The recent federal investigation has led the MGCB to focus closely on the risks associated with player proposition wagers. These bets, which focus on individual performance statistics instead of the game’s final result, were reportedly exploited in the NBA scandal.
Executive Director Williams noted that “certain types of prop bets present a higher risk of manipulation.” This risk is significantly elevated when a wager is tied to insider knowledge or player behavior. The MGCB is now assessing whether current safeguards are strong enough or if additional restrictions on prop bets will be necessary to secure the market.
Williams called the federal case “a wake-up call for the entire industry.” The MGCB plans to use findings from the ongoing investigation to shape future regulatory actions and strengthen the state’s sports betting framework.
