Michigan Court Blocks Kalshi Sports Contracts: What the CFTC Clash Means for Compliance
A Michigan circuit court has issued a temporary restraining order barring prediction market platform Kalshi from offering sports event contracts to state residents, making Michigan the second US state to impose a court-ordered ban of this kind. The ruling sharpens a jurisdictional conflict between state gambling regulators and the federal Commodity Futures Trading Commission (CFTC) that compliance and legal teams at firms servicing event-contract platforms cannot afford to ignore.
What the Michigan Court Ordered
Terms of the restraining order
Ingham County Circuit Court Judge Rosemarie Aquilina issued the temporary restraining order after Michigan's attorney general accused Kalshi of violating the state's gambling laws. The order runs for 14 days, expiring on 13 July, and requires Kalshi to enforce geolocation controls that prevent Michigan residents from accessing sports betting contracts on the platform.
The financial stakes are significant: the court set a penalty of $120,000 for each day the platform fails to meet the geolocation requirements. Judge Aquilina wrote that Michigan residents faced irreparable harm from being, in her words, exploited by a sports betting operation presented as an investment opportunity.
How Michigan fits the broader pattern
Michigan is the second state to obtain a court order against Kalshi's sports contracts; an earlier temporary ban was secured in March. On 17 June, multiple prediction market platforms, including Kalshi and Polymarket, were targeted by state authorities accusing them of running unlicensed sports betting operations. More than a dozen states have now initiated legal proceedings against prediction market operators.
The CFTC Jurisdictional Argument
Federal pre-emption as a defence
The CFTC has entered the debate, arguing that federally regulated event contracts fall under its exclusive authority. This federal pre-emption argument is central to how Kalshi and similar platforms have sought to defend their operations: if the CFTC has sole jurisdiction over event contracts, state gambling statutes would not apply.
The tension is not new, but the volume and speed of state-level enforcement actions in 2025 and 2026 have forced the question into courts across the country simultaneously. The outcome of these cases will likely determine whether prediction markets can operate nationally under a single federal framework or must obtain state-by-state gambling licences.
Why the CFTC angle matters for compliance teams
For accounting firms, auditors, and CFOs whose clients operate on or interact with event-contract platforms, the jurisdictional uncertainty creates a layered risk picture. A platform that is CFTC-registered but faces state-level injunctions occupies a legally ambiguous space. Revenue recognition, customer liability provisions, and AML programme design all need to account for the possibility that a platform's operating model could be disrupted by further state orders at short notice.
Firms conducting due diligence on prediction market clients should be stress-testing whether those clients maintain adequate geolocation controls and whether their compliance programmes are calibrated for both federal event-contract rules and state gambling statutes. Reviewing OFAC SDN cryptocurrency address screening obligations alongside state-level licensing status is a practical starting point for any AML gap analysis in this sector.
Market Context: Why Enforcement Is Accelerating Now
Record trading volumes tied to the FIFA World Cup
Enforcement pressure has intensified at the same moment that prediction market volumes have reached historic highs. Daily taker volume across prediction markets hit $713 million on 20 June, driven largely by sports contracts tied to the 2026 FIFA World Cup, which began on 11 June. Monthly sports betting volume on the two largest prediction market platforms rose sharply, with one platform recording a 40% increase to $9.5 billion and another a 175% rise to $5.3 billion.
Analysts had projected that the World Cup would generate more than $3 billion in incremental sports betting handle and between $5 billion and $10 billion in additional prediction market volume. The single contract on the tournament winner has alone generated over $3.5 billion in trading volume on one major platform.
New user onboarding and its compliance implications
A separate study of approximately 857,000 users found that around 60% of World Cup bettors on prediction markets were interacting with a blockchain for the first time during their entry. That figure carries real compliance weight: a large cohort of first-time on-chain users transacting at high volumes, through platforms whose regulatory status is contested, is precisely the environment in which KYC gaps and AML control failures tend to emerge.
Firms advising prediction market operators or their investors should be asking whether onboarding controls were scaled in line with this volume surge, and whether enhanced due diligence was applied to high-value first-time users. The principles that underpin robust blockchain analytics data quality standards for compliance teams are directly relevant to monitoring this type of rapid user growth.
Practical Implications for Firms
Licensing risk and financial statement disclosures
Any firm with audit or advisory responsibility for a prediction market platform operating sports contracts in the US faces an immediate question about going-concern and contingent liability disclosures. With daily fines of $120,000 already on the table in Michigan alone, and more than a dozen other states in active litigation, the aggregate exposure is material. Auditors should be satisfied that clients have quantified and disclosed the range of potential penalties across all affected jurisdictions.
Revenue recognition under uncertainty
Platforms that continue to generate revenue from sports contracts while subject to state injunctions may face questions about whether that revenue is recognisable under standard accounting frameworks if there is a realistic prospect of disgorgement or regulatory clawback. The legal uncertainty around CFTC pre-emption makes this harder to resolve cleanly, and firms should document their basis for any revenue recognition judgements carefully.
AML programme design for event-contract platforms
If state courts ultimately determine that prediction market sports contracts constitute gambling rather than commodity trading, the AML obligations that apply to those platforms could shift significantly. Gambling operators in the US are subject to Bank Secrecy Act obligations including currency transaction reports and suspicious activity reports. Platforms currently operating under a CFTC framework may not have built their AML programmes to meet those requirements. Compliance teams advising these platforms should begin mapping the gap now rather than waiting for final court rulings.
FAQs
What exactly did the Michigan court order require Kalshi to do?
The temporary restraining order, issued by Ingham County Circuit Court Judge Rosemarie Aquilina, requires Kalshi to enforce geolocation controls that prevent Michigan residents from placing bets on sports event contracts. The order carries a daily fine of $120,000 for non-compliance and is in effect for 14 days from the date of issue, expiring on 13 July.
Why is the CFTC involved, and what is the federal pre-emption argument?
The CFTC regulates event contracts at the federal level and has argued that its authority over these instruments is exclusive, meaning state gambling laws should not apply to CFTC-regulated platforms. Kalshi and similar platforms have used this argument to contest state enforcement actions. Courts have not yet definitively resolved which framework prevails.
How many states have taken action against prediction market operators?
Based on the available information, more than a dozen states have initiated legal proceedings against prediction market operators. Michigan is the second state to secure a court-ordered ban specifically against Kalshi's sports contracts, following an earlier order in March.
What AML and KYC risks should compliance teams focus on given the volume surge?
The combination of record trading volumes and a large proportion of first-time blockchain users onboarded during the World Cup period creates elevated exposure to KYC gaps and suspicious transaction patterns. Compliance teams should verify that onboarding controls scaled appropriately, that enhanced due diligence was applied where warranted, and that transaction monitoring rules are calibrated for the volume levels seen during the tournament period.
How should auditors treat the potential state-level fines in financial statements?
Where a platform is subject to active injunctions or is at real risk of further state orders, auditors should assess whether the aggregate potential penalties across all affected states represent a material contingent liability requiring disclosure. The $120,000 daily rate in Michigan alone illustrates how quickly exposure can accumulate, and management should be able to demonstrate a documented assessment of the range of outcomes.
