The Backstory

Michigan’s test of federal prediction-market power

Michigan’s confrontation with Kalshi has become a leading test of where federally regulated event contracts end and state-regulated sports betting begins. The immediate dispute turns on pending trades by Michigan residents after an Ingham County judge temporarily blocked Kalshi from offering sports event contracts in the state. The Commodity Futures Trading Commission then ordered Kalshi to honor those trades, saying federal derivatives law requires registered exchanges to operate as a single national market with impartial access.

That position directly challenges the theory advanced by Michigan Attorney General Dana Nessel and state gaming officials: If a product lets residents stake money on sports outcomes, it should be treated like sports betting and comply with state licensing, tax and consumer-protection rules. Kalshi says its contracts are federally regulated financial products. Michigan says they are functionally wagers. The result is a jurisdictional fight with consequences beyond one platform or one state.

The stakes have risen because prediction markets are no longer niche political or economic forecasting tools. Kalshi’s sports-related activity has expanded rapidly, putting it in closer competition with licensed sportsbooks while operating under a different regulatory structure. That growth has sharpened questions for states that spent years building tightly controlled online betting markets after the fall of the federal sports-wagering ban.

Sports contracts moved the fight into gambling territory

Kalshi’s rise accelerated during college basketball’s marquee tournament, when the company reported a surge in activity that underscored how much consumer demand exists for event-based sports trading. During March Madness, Kalshi recorded more than US$800 million in trading during the first weekend alone, nearly double the amount traded across the entire tournament a year earlier, according to a prior report on Kalshi’s March Madness trading record.

Those figures mattered because they made the policy dispute harder to frame as an abstract derivatives question. Basketball-related contracts accounted for a large share of Kalshi’s trading at a time when traditional sportsbooks expected billions in tournament handle. To state regulators, that overlap reinforced the argument that sports event contracts can compete with licensed wagering products while avoiding state taxes, responsible-gaming obligations and market-entry reviews.

The NCAA also pushed the issue into the public arena. Its leadership has warned that college sports markets could create integrity risks and expose student-athletes to pressure or harassment. Those concerns fit squarely within the type of policy rationale states have used to justify strict sportsbook oversight. Kalshi and its supporters counter that prediction markets are overseen by a federal commodities regulator and operate through standardized contracts rather than conventional bookmaker odds.

That distinction is central to the Michigan clash. A sportsbook generally offers bets under a state license and pays state taxes. A federally registered derivatives exchange operates under the Commodity Exchange Act. If sports event contracts are treated as swaps or derivatives subject to CFTC supervision, states may have limited ability to block them. If they are treated as gambling, operators may need state-by-state approval.

A state already aggressive against unlicensed gambling

Michigan’s position is also shaped by a broader enforcement campaign against unauthorized gambling operators. The Michigan Gaming Control Board has repeatedly warned that offshore and unlicensed sites expose residents to unfair terms, withheld winnings, weak data safeguards and little recourse when disputes arise. That posture helps explain why the state has been unwilling to treat sports event contracts as merely a financial-market innovation.

In one recent action, the regulator issued cease-and-desist orders to 11 illegal online gambling operators accused of targeting Michigan residents. The board said the sites accepted wagers without authorization and used payment methods including credit cards, digital wallets and cryptocurrencies. The enforcement notice emphasized consumer risk as much as statutory compliance, a theme that has carried through Michigan’s response to prediction markets.

The agency also targeted Panama-based SportsBetting.ag and BetOnline after finding the platforms offered unauthorized wagering on sports, casino games, horse racing, esports and other events. In its orders against SportsBetting.ag and BetOnline, the regulator cited violations of Michigan’s internet gaming, casino and penal laws and warned that noncompliance could trigger further action with the attorney general’s office.

Kalshi is not an offshore casino, and its legal defense rests on a different foundation. But Michigan’s enforcement history shows why officials are sensitive to any product that accepts money from residents on event outcomes outside the state’s licensed gaming framework. The state has built a regulated market that depends on licensing standards, tax collection, geolocation, age checks and responsible-gaming rules. Allowing a parallel sports prediction market could weaken that structure if consumers view the products as substitutes.

TwinSpires showed Michigan’s willingness to confront licensed firms

Michigan’s campaign has not been limited to offshore or anonymous operators. The state also moved against TwinSpires, an affiliate of Churchill Downs Technology Initiatives Company, after the company continued advance deposit wagering for Michigan residents despite a regulator directive to stop. The case showed that Michigan is prepared to act even against established gambling businesses when officials believe state law has been breached.

The Michigan Gaming Control Board said state law required advance deposit wagering and simulcast wagering to be tied to a licensed racetrack hosting live racing. Because no Michigan racetrack held the necessary license, the board directed providers to halt service. Most complied, but TwinSpires did not, prompting a summary suspension detailed in the report on Michigan’s order for TwinSpires to shut down wagering activity.

That episode is relevant because it illustrates the regulator’s view that market access depends on state-law conditions, not simply a company’s national profile or compliance elsewhere. Kalshi’s argument is different because it invokes federal preemption. Still, Michigan’s regulatory pattern is consistent: If residents can place money at risk on outcomes through a product the state views as gambling, officials expect the operator to have clear state authorization.

The Kalshi matter raises a harder question than TwinSpires because the CFTC has inserted itself on the other side. Michigan can order a gambling company to stop, but a federally registered exchange can argue that state-by-state restrictions undermine the national market Congress created for derivatives trading. The CFTC’s order to honor Michigan trades makes that conflict explicit.

Kalshi’s scale raises the cost of ambiguity

The dispute is unfolding as Kalshi becomes a much larger financial and technology business. The company recently reported a US$1 billion Series F funding round led by Coatue, lifting its valuation to US$22 billion. It also said trading volume had risen 800% over six months and that it accounted for 90% of U.S. prediction market activity, according to a report on Kalshi’s US$22 billion valuation and volume surge.

That scale changes the regulatory calculus. A small market can operate in gray areas with limited systemic impact. A fast-growing platform backed by major investors and seeking institutional users can force regulators, courts and lawmakers to settle boundaries. Kalshi has said it wants to expand into hedge funds, asset managers, proprietary trading firms and insurance companies, suggesting its ambitions go well beyond consumer sports activity.

For the CFTC, preserving a uniform national market is a core principle. Fragmenting access by state residence could make event-contract exchanges harder to operate and create compliance conflicts across jurisdictions. For Michigan, however, uniform access can look like a federal end run around state gambling laws. If one exchange can offer sports markets nationwide under commodities law, licensed sportsbooks may argue they face an uneven playing field.

The outcome will influence more than Kalshi’s Michigan business. Other prediction markets, including Polymarket, have faced legal resistance in the state, and courts are beginning to sort out whether sports-event contracts fall within federal commodities oversight or state gambling authority. Until that boundary is settled, each enforcement move risks becoming part of a larger precedent.

Why the next rulings matter

The Michigan fight now sits at the intersection of consumer protection, federal preemption, sports integrity and market innovation. A ruling favoring Michigan could strengthen state authority to block sports prediction markets unless operators obtain gambling licenses. That would preserve the state-by-state model that governs online sportsbooks and casinos, but it could also limit federally regulated exchanges from offering uniform products nationwide.

A ruling favoring Kalshi and the CFTC could accelerate the growth of sports event contracts and pressure states to rethink how they regulate wagering-like products outside traditional gaming statutes. It could also invite more platforms to design contracts around sports, politics and other real-world outcomes while relying on federal registration rather than state gambling approval.

For consumers, the immediate issue is access to trades. For regulators, it is control over the architecture of legal betting and event speculation. Michigan’s response signals that states are unlikely to concede that ground without a fight, especially as prediction markets grow large enough to affect tax revenue, sportsbook competition and public confidence in regulated gambling.
