CFTC Blocks Michigan Court Directive on Kalshi Trades Citing Uniform Market Rules and Systemic Risk

Key Takeaways

• CFTC Emergency Action: The agency stayed Kalshi’s proposed emergency rule for 90 days including a 30-day comment period and ordered the platform to honor trades a Michigan court required voided.
• Court Timeline: Michigan ban on Kalshi sports event contracts issued June 29 initially for 14 days later extended with geofencing deadline Aug. 12 and July 6 clarification that trades with Kalshi Trading must be voided cancelled and refunded.
• Volume Data: Kalshi Trading represented less than 6% of sports making volume in November 2025 suggesting $310 million sports volume that month before overall volume grew by about five times.
• Core Regulatory Stance: Canceling executed trades risks shattering public confidence cascading effects on related contracts and distortions away from supply and demand forces.

Kalshi sports volume has scaled sharply. The platform’s own November 2025 data showed its in-house market maker at less than 6% of making volume with implied sports volume near $310 million before fivefold growth. That expansion now collides with a Michigan court order and a firm CFTC pushback.

According to reporting by InGame, the CFTC rejected Kalshi’s emergency rule change. The agency invoked emergency authority to force fulfillment of the trades. Kalshi now sits between conflicting directives.

Michigan Court Order Targets Kalshi Sports Contracts

On June 29, a Michigan court banned Kalshi from offering listing matching executing clearing or settling any contracts classed as sports betting to anyone in the state. The initial 14-day prohibition was extended. The court required geofencing rather than address verification by end of day Aug. 12.

After the order Kalshi requested clarification on existing positions. In a July 6, 2026 correspondence to the parties, the court clarified that trades between Michigan residents and Kalshi Trading, Kalshi’s in-house market making arm, must be “voided, cancelled and refunded.”

Kalshi Trading has drawn criticism for potentially undermining the exchange’s neutral stance. The emergency filing described its share as a minute percentage of sports trading volume. Critics question whether an in-house maker aligns with impartial market design.

Kalshi Submits Emergency Rule to Force Liquidations

Kalshi filed a proposed emergency rule with the CFTC. The rule would require the exchange to force-liquidate open positions of users the court identified for voiding. It would pay out the shortfall between the liquidation value of any open positions and the original stake.

The filing warned that a broader liquidation order affecting all sports positions of a Michigan-based user would demand more extreme steps and severely impact members nationwide. If it focuses on less liquid markets, its volume may not necessarily increase as overall volume on the exchange does.

In late November 2025, Kalshi co-founder Luana Lopes Lara wrote that Kalshi Trading was less than 6% of the making volume for sports contracts during that month.

CFTC Rejects Rule Stay and Accuses Michigan of Bullying

The CFTC declined to accept the emergency rule. It stayed the change for 90 days which includes a 30-day comment period before a final decision. By then many trades may have settled naturally.

“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,” said Chairman Michael S. Selig. “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. The Commission will not allow states or state courts to bully registered entities into violating the Commodity Exchange Act and CFTC regulations.” The order stressed uniform national markets impartial access and continued public confidence in derivatives execution and clearing.

Unwinding Trades Threatens Market Certainty and Liquidity

The CFTC order warned that immediate approval of the rule would risk shattering public confidence. Traders might worry their positions could be unwound a week or a year later. The release cited an 1864 Supreme Court case noting the rule of law does not allow a contract fairly made to be annulled.

Participants may have based budgeting and risk management decisions on expected outcomes. Related or corollary contracts could face significant price volatility. The order flagged potential systemic issues affecting multiple exchanges.

It concluded that forced liquidation causes distortions and produces a marketplace that does not directly represent supply and demand. One X voice captured the tension. @TheProspect posted 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.

Other voices including @tphillips and @a_kane47 highlighted concerns over busted trades affecting counterparties or leaving clearinghouses exposed.

What the Coverage Underemphasizes

Reporting from InGame Betting News sigma.world and Bloomberg Law News details the legal standoff and quotes effectively. The combined coverage underemphasizes the operational load on platforms. When federal and state rules collide after trades execute operators face simultaneous compliance risks that no geofence fully resolves.

From the supplier side these conflicts surface exactly where liquidity is thinnest. Prediction platforms scaling sports-like contracts must now build compliance assumptions around potential retroactive state orders even after CFTC approval. That raises costs and chills participation in thinner markets.

Tribal operators and sports tech partners watching event contract growth see a signal here. Federal defense of national uniformity may limit state-level bans but it does not eliminate the uncertainty that hits risk models and promo budgets first.

The Operational Calculus Ahead

Kalshi told InGame it is reviewing the CFTC order and evaluating next steps. The immediate path likely involves navigating the 90-day stay while preparing arguments for the comment period.

Data on the table shows these markets are no longer experimental. Fivefold volume growth since November 2025 with Michigan-level exposure now triggering federal intervention means operators must treat regulatory overlap as a core risk variable. Certainty in executed trades is not optional for liquidity.

Platforms that integrate direct feeds robust rule engines and scenario planning for state-federal friction will hold an edge. The CFTC has drawn its line. The test will be whether that line holds as more states test similar boundaries before World Cup 2026 volumes arrive.
