CME sues CFTC over Kalshi’s Bitcoin perpetual contract

CME Group filed a lawsuit against the Commodity Futures Trading Commission after the agency approved KalshiEX’s BTCPERP Bitcoin perpetual contract. Kalshi submitted the contract under CFTC Regulation 40.3 on May 28 and the agency approved it on May 29.

The BTCPERP references spot Bitcoin, has no expiry date and functions as a perpetual futures instrument. Perpetual contracts use continuous funding or margining mechanisms to keep prices aligned with the underlying asset. They may allow high leverage and include automatic liquidation when positions move sharply.

CME’s complaint, filed in mid‑June, argues the BTCPERP should be regulated as a swap under the Dodd‑Frank Act rather than as a futures contract. The complaint contends that swap classification would trigger different disclosure, registration and clearing requirements. CME’s chief executive publicly announced the company would challenge the CFTC approval in court.

Kalshi has reported more than $5 billion of perp volume since the product launched. Between May 17 and June 10, perpetual contracts tied to a pre‑IPO company generated about $3.2 billion in volume across eight exchanges, with one platform accounting for roughly $2.1 billion of that total.

After the CFTC approval, shares of several incumbent derivatives exchanges moved lower. The approval has prompted industry groups and state officials to submit comments to the CFTC’s prediction‑market docket and related rulemaking processes.

The Futures Industry Association and its Principal Traders Group asked the CFTC to clarify definitions for perpetual derivatives and to open a formal rulemaking, citing trading and clearing risks. A bipartisan coalition of 41 state attorneys general urged that sports‑related event contracts remain subject to state gaming laws. Several state gaming boards and gaming industry organizations also filed comments questioning federal preemption of state authority for some event markets.

The CFTC proposed new rules for event contracts on June 10 and set a public comment period through July 27. On June 12 the agency filed suit against the state of New Mexico to block state gaming enforcement actions targeting CFTC‑registered contract markets.

Other trading venues have combined onshore crypto perpetuals with outcome or event markets. Some platforms that built volume on perpetual futures have added outcome markets tied to economic releases and policy decisions, allowing users to trade derivative and event contracts in a single account.

The legal challenge and the CFTC’s pending rule proposals raise questions about whether perpetual contracts that reference spot assets should be classified as futures or swaps, how federal registration interacts with state gaming laws when platforms offer event markets, and what clearing and market‑integrity standards venues must meet. Court rulings and final agency rules are pending.
