Michigan regulators are intensifying their campaign against prediction market operator Kalshi, expanding the battle beyond the courtroom and into the responsible gambling sector after securing a temporary restraining order against the company’s sports event contracts.
The Michigan Gaming Control Board (MGCB) confirmed this week that it is withdrawing from the National Council on Problem Gambling (NCPG) due to the organization’s partnership and investment relationship with Kalshi, arguing that the move undermines state-level gambling enforcement and consumer protection efforts.
The decision comes just days after the Ingham County Circuit Court granted a temporary restraining order against KalshiEX, immediately prohibiting the platform from offering sports-related event contracts to Michigan residents. The order, signed by Judge Rosemarie Aquilina, also threatens fines of up to $120,000 per day for noncompliance.
While the restraining order itself marked a significant development in the ongoing legal fight surrounding prediction markets, Michigan regulators are now placing equal emphasis on what they view as the broader public health implications tied to the rapid expansion of sports event contracts.
MGCB Executive Director Henry Williams sharply criticized the NCPG’s relationship with Kalshi, accusing the prediction market platform of operating what he described as an illegal gambling business while presenting sports betting as a form of investing.
In a letter addressed to NCPG Executive Director Heather Maurer, Williams argued that Kalshi’s framing of sports event contracts as financial instruments conflicts with responsible gambling principles.
“I am deeply concerned that Kalshi’s attempts to distinguish sporting event contracts from other forms of sports betting by claiming that its offerings are akin to ‘investment’ or ‘insurance’ products directly undermine a foundational message of responsible gaming: that gambling in any form is for entertainment purposes only,” Williams wrote.
Michigan regulators have repeatedly emphasized that licensed sportsbooks operating in the state must comply with strict consumer protection requirements, including age verification, self-exclusion programs, deposit limits, and responsible gambling safeguards. According to the MGCB, Kalshi operates outside those requirements while still offering products that resemble traditional sports betting markets.
The regulator also expressed concern that partnerships between gambling harm prevention organizations and prediction market companies could create confusion among consumers regarding regulatory oversight and player protections.
“NCPG’s partnership with Kalshi also creates substantial confusion by suggesting to the public that Kalshi is subject to the same consumer protections, licensing requirements, and regulatory oversight as licensed sports betting operators,” Williams stated.
The clash reflects the increasingly tense national debate surrounding sports event contracts and prediction markets, which continue to expand under federal oversight from the Commodity Futures Trading Commission (CFTC). Companies such as Kalshi maintain that their platforms operate as peer-to-peer financial exchanges rather than gambling businesses, a position many state regulators continue to reject.
Michigan’s legal challenge arrives as Kalshi experiences explosive growth. The platform reportedly processed more than $17 billion in trading volume within the World Cup’s opening weeks, highlighting the popularity surrounding prediction-based sports markets.
The MGCB said its enforcement actions are designed to protect consumers, particularly younger audiences and individuals vulnerable to gambling-related harm, while also preserving tax revenue that supports education, addiction treatment, public safety programs, and other state initiatives.
