CFTC Blocks Kalshi Trade Cancellations

The Signal

The CFTC ordered Kalshi not to cancel and refund trades for Michigan residents, directly blocking the platform from complying with a Michigan state court order, according to CoinDesk, Reuters via Yahoo Finance, and Law.com. The agency stayed Kalshi’s emergency rule application to unwind the trades, saying the state order would force a CFTC-registered designated contract market to violate federal commodities law.

CFTC Chair Mike Selig framed the order as a defense of federal exclusivity over registered event-contract exchanges. “The Commission will not allow states or state courts to bully registered entities into violating the Commodity Exchange Act and CFTC regulations,” he said.

Michigan is the first state to try to reach directly into completed Kalshi transaction activity, according to the CFTC. Prior state fights have focused on blocking access, enforcement threats, or whether sports-linked contracts constitute illegal gambling; this one tests whether a state court can force a federally regulated DCM to reverse trades already executed on its books.

Kalshi said it is reviewing the order and considering next steps. The intervention gives the company regulatory cover in the short term, but it also raises the stakes of the broader federal-versus-state fight around sports event contracts.

The Mechanism

• Kalshi gets a federal shield against forced trade unwinds. The CFTC’s order protects market finality on a registered exchange, which is core infrastructure for any venue trying to attract active traders, market makers, and institutional-style flow.

• The CFTC is treating state-ordered cancellations as a market-structure problem, not just a jurisdictional dispute. If courts can force retroactive trade breaks by resident location, DCM order books become fragmented after execution, with settlement risk varying by state.

• Michigan’s order targets Kalshi’s sports-linked markets, but the CFTC response applies to the exchange’s federal status. The agency’s position is that a state cannot require a registered contract market to breach its Commodity Exchange Act obligations, even if the state views the underlying contract category as gambling.

• The action strengthens Kalshi’s U.S.-regulated positioning against offshore competitors. Polymarket is pushing distribution through crypto apps outside the U.S.; Kalshi is using CFTC registration as both a compliance moat and a litigation weapon inside the U.S.

• The dispute shifts attention from contract approval to post-trade integrity. Prediction markets have spent years fighting over what can be listed. This order asks who controls the ledger after trades clear.

• Investors are underwriting the regulated-exchange thesis while the litigation expands. ERShares’ XOVR disclosed a $30 million Kalshi investment this week, making the state-federal fight part of the company’s valuation story rather than a side issue.

The Landscape

Market Position: Kalshi remains the dominant onshore, CFTC-regulated prediction market venue, claiming more than 90% of U.S. prediction-market activity and $178 billion in annualized trading volume, up from $52 billion six months earlier. The company is simultaneously expanding trader infrastructure through Kalshi Pro, adding perpetual-futures-style workflows, and attracting private-market exposure through XOVR’s $30 million allocation. Polymarket is taking the opposite route: its new Blockchain.com integration puts offshore/global event markets inside a crypto brokerage app with tens of millions of users, while its U.S. affiliate pursues separate regulated registrations.

Regulatory Environment: The CFTC is now openly contesting state attempts to regulate prediction-market access and trade handling for federally registered venues. Michigan’s order follows pressure from nearly two dozen states and Native American tribes seeking to block event-contract companies from offering sports-related markets under state gaming laws. The agency’s latest move narrows the question for courts: whether CFTC registration preempts state gambling enforcement when a DCM lists and processes event contracts that states consider sports wagering.

Key Data

• 1 CFTC order blocking Kalshi from canceling and refunding Michigan resident trades tied to the state court dispute.

• Nearly two dozen states and Native American tribes are seeking to restrict or penalize event-contract businesses over sports-related markets, according to Reuters.

• $178 billion in Kalshi annualized trading volume, up from $52 billion six months earlier, per the company’s recent disclosures.

• More than 90% of U.S. prediction-market activity is claimed by Kalshi, according to its latest public positioning.

• $30 million was invested in Kalshi by ERShares’ XOVR ETF as part of its latest rebalance, one of the fund’s largest private-company holdings.

What’s Next

Kalshi’s next filing or response to the CFTC order will show whether the company leans fully into federal protection or seeks a narrower path around the Michigan court mandate. The larger catalyst is the next court ruling on whether state gaming regulators can restrict sports-linked event contracts offered by a CFTC-registered DCM. A win for the CFTC would harden Kalshi’s onshore moat; a win for Michigan would introduce state-by-state post-trade risk into the regulated prediction-market model.
