CME Group filed a federal lawsuit on June 18, 2026, challenging the CFTC's approval of Kalshi's bitcoin perpetual futures contract, arguing the product should be regulated as a swap rather than a futures contract under the Commodity Exchange Act and Dodd-Frank.
The complaint, Case 1:26-cv-02157, was filed in the U.S. District Court for the District of Columbia. It targets both the CFTC's May 29 order approving KalshiEX's BTCPERP contract and an accompanying policy statement on perpetual contracts published in the Federal Register on June 3.
The approved BTCPERP product is cash-settled, references the CF Benchmarks Bitcoin Real Time Index, trades around the clock seven days a week, and uses periodic funding payments to track spot bitcoin. Each contract unit represents 1/10,000 of one bitcoin.
Bitcoin changed hands near $62,344 at press time, down roughly 2.96% over 24 hours, setting a risk-off backdrop for the legal battle.

CEO Terrence Duffy previewed the legal theory before the filing was submitted.
"When there's two parties exchanging payments to each other, that's deemed a swap."

The distinction matters because swaps and futures carry different regulatory, capital, and tax requirements. CME alleges the CFTC repeated Kalshi's own reasoning almost verbatim in its approval order, according to the complaint, and unlawfully departed from the agency's prior position that perpetuals are swaps.
The complaint also warns the approval opened the door for similar digital-commodity perpetuals to be self-certified by other futures exchanges. That concern is already materializing: Kalshi self-certified a SOLPERP futures contract on June 2, days after the BTCPERP approval, as the broader push into tokenized and structured crypto products accelerates.
The CFTC approved the BTCPERP contract under Commodity Exchange Act section 5c(c)(4) and Regulation 40.3. Its June 3 Federal Register policy statement narrowed the scope, stating that perpetuals on asset classes not covered by the bitcoin order should receive case-by-case review.
That scope-limiting language is central to the dispute. CME argues Congress and Dodd-Frank already drew the line: if two parties exchange periodic payments, the product is a swap regardless of what the exchange calls it. The CFTC sees it differently.
Kalshi spokesperson Elisabeth Diana called the lawsuit competitive posturing rather than a genuine legal challenge, stating, "This isn't about the law, it's about the fear of competition." A CFTC spokesperson separately described the suit as "lawfare" and "frivolous."
The case could shape how state and federal regulators classify an expanding range of crypto-linked leverage products. If the court sides with CME, perpetual contracts would face swap-dealer registration, margin rules, and reporting obligations that futures exchanges can avoid.
Roughly $29.57 billion in 24-hour BTC volume shows the lawsuit landed during an active trading session, not a thin weekend window.

Source: CoinGeckoAccording to CME's complaint as summarized by Courthouse News, the CFTC order has already enabled more than $1 billion in trades in newly listed crypto perpetuals. If the court grants an injunction, Kalshi may need to suspend or restructure the product.
The case extends beyond these two firms. Any DCM that planned to self-certify perpetual contracts under the CFTC's new policy statement faces uncertainty until the litigation resolves. For retail traders who gained access to regulated bitcoin leverage through Kalshi's platform, the outcome will determine whether that access survives or reverts to offshore venues.
The broader crypto industry is watching closely. With the Crypto Fear & Greed Index at 14, signaling extreme fear, the legal cloud over U.S. perpetual futures adds another layer of caution to a market already under pressure.
