Can Federal Derivatives Authority Override a State Court Ban on Kalshi Prediction Market Trades?

Key Takeaways

• Federal Preemption Asserted: The CFTC stayed Kalshi’s emergency rule change and invoked emergency powers to force the platform to honor trades that a Michigan court ordered voided, cancelled, and refunded.
• June 29 Court Order: Michigan’s 30th District Court banned Kalshi from offering, listing, matching, executing, clearing, or settling sports event contracts, later extended with a geofencing requirement by August 12.
• 90-Day Stay: The CFTC imposed a 90-day stay on the rule change, including a 30-day comment period, citing risks to market certainty and a potential cascading effect on the entire marketplace.
• Volume Context: Kalshi Trading represented less than 6% of making volume for sports contracts in November 2025, when sports volume reached about $310 million, with overall volume growing five times since then.

What happens when a state court deems certain prediction market trades illegal gambling and orders them unwound, only for the federal regulator to step in and demand they stand? The CFTC’s swift intervention in the Michigan Kalshi dispute marks a direct assertion of federal authority over event contracts.

According to reporting by InGame, on June 29 a Michigan court banned Kalshi’s sports event contracts within the state. That ban was later extended, requiring geofencing rather than reliance on users’ addresses, by the end of the day August 12. The order prohibited Kalshi from offering, listing, matching, executing, clearing, or settling any contracts classed as sports betting to anyone in Michigan.

After the initial order, Kalshi sought clarification on existing trades. In a July 6, 2026 correspondence, the court specified that trades between Michigan residents and Kalshi Trading, the platform’s in-house market making arm, must be voided, cancelled, and refunded. Kalshi then submitted an emergency rule filing to the CFTC on Sunday outlining forced liquidation of those specific positions.

CFTC Rejects Michigan’s Unwinding Mandate

The CFTC rejected Kalshi’s proposed emergency rule change and instead stayed it for 90 days. This includes a 30-day comment period after which a final decision will be made. By that point many of the trades in question would likely have settled naturally.

As reported by Bloomberg Law News, the CFTC invoked emergency powers to halt any trade cancellations and ordered Kalshi to honor the contracts. The agency argued that allowing the unwinding would violate core principles under the Commodity Exchange Act requiring a uniform national market in derivatives transactions.

“Market participants must have impartial access to CFTC-regulated markets and registered entities must adopt transparent access criteria that are applied in a non-discriminatory manner,” the agency stated in its release. It further emphasized its role in ensuring continued public confidence in derivatives markets by guaranteeing market resilience and predictability.

CFTC Chair Michael S. Selig accused Michigan of “bullying” Kalshi into unwinding trades. “A state cannot force a DCM to violate its obligations, and federal law does not permit a DCM to discriminate against a state’s residents,” Selig said. “Canceling trades that have already been executed is an unprecedented step that risks a cascading effect on the entire marketplace and undermines the certainty in contracting that is a necessary component of a functioning market.”

Market Confidence and Systemic Risk Concerns

The CFTC order warned that permitting forced liquidations could erode faith across the marketplace. If traders believe positions executed today might be unwound weeks or even a year later, public confidence would shatter.

“If the Commission were to allow the Emergency Rule to take effect immediately, it would risk shattering public confidence by giving traders cause to worry that the trades they execute today may be unwound a week — or a year — later,” the order stated, citing an 1864 Supreme Court case on the rule of law not allowing a contract fairly made to be annulled.

It added that some market participants may have made budgeting and risk management decisions based on expected outcomes. Related or corollary contracts could face significant price volatility, risking a more systemic market issue affecting multiple exchanges. “In general, forced liquidation of trades will cause distortions that could give rise to a marketplace that does not directly represent the forces of supply and demand.”

This perspective aligns with commentary from market observers. As @a_kane47 posted on X: “CFTC is correct here. Can’t just cancel trades made in the past. Each trade has two sides, so either the clearinghouse is stuck with the risk (not how clearinghouses are designed to operate), or the counterparties to the affected trades also have their trade busted? Two terrible…”

Similarly, @dan_bernstein_ noted: “The CFTC does invoke impartial access in today’s order not to cancel trades that have already been executed in Michigan.”

State-Federal Clashes and Parallels to Tribal Sovereignty

This confrontation highlights longstanding tensions between state gaming laws and federal oversight of event contracts. Michigan’s classification of these products as sports betting directly challenges the CFTC’s framework treating them as derivatives.

The episode carries echoes of broader questions around tribal sovereignty in prediction markets that SCCG Management has tracked. Just as tribes assert foundational rights against state overreach in gaming, the CFTC here draws a line on uniform national standards that cannot yield to fragmented state directives.

Kalshi now sits at the center of conflicting mandates. A Kalshi spokesperson told InGame: “We are currently reviewing the CFTC’s order and evaluating our next steps.” The platform risks Michigan court sanctions if it honors the trades or CFTC action if it cancels them.

Critics have raised questions about Kalshi Trading’s role as in-house market maker. An older post from co-founder Luana Lopes Lara on X defended against related claims: “I try to avoid engaging with stupid lies on X, but this is a pure smear campaign. This account, and others, are being paid by our competitor to amplify a baseless lawsuit. The allegations are false and reveal a fundamental (and maybe intentional) misunderstanding of how these…”

What Combined Coverage Underemphasizes

Reporting from InGame, Bloomberg Law News, The Crypto Times, sigma.world, and the CFTC’s own press release captures the immediate legal standoff and rhetoric around bullying and market certainty. Yet the synthesis reveals less emphasis on longer-term competitive dynamics for prediction platforms navigating patchwork state restrictions.

From an operator and investor lens, this federal push may accelerate platform decisions on geographic exposure and product design. It also spotlights the unresolved classification debate: when does an event contract cross into prohibited sports betting? Coverage has not deeply probed how sustained clashes could slow the very convergence of prediction markets with sports and media that has fueled recent growth.

@TheProspect highlighted one dimension on X: “Sports betting and other gambling products masquerading as “event contracts” have exploded since Trump regained office, entirely thanks to the administration’s control of a radically transformed CFTC.”

The CFTC’s action may deter similar state-level challenges, but it does not resolve underlying regulatory ambiguity.

The Preemption Inflection Point

This dispute represents more than a jurisdictional spat. It signals a structural shift where federal derivatives authority seeks to preempt state gaming classifications that threaten market predictability. For client-partners evaluating prediction market opportunities, the message is clear: federal backstops can provide breathing room, yet they do not eliminate compliance risk across multiple regimes.

Operators and investors should track how this 90-day review period unfolds and whether it sets precedent for other states. The outcome will likely influence the pace of prediction market expansion versus traditional gambling verticals. Clearer federal boundaries, paired with pragmatic state engagement, remain essential to preserving the innovation and liquidity that define this emerging sector.
