The CFTC approved KalshiEX’s BTCPERP contract on May 29, a day after Kalshi filed it under Regulation 40.3.
The contract references point to Bitcoin, have no expiration date and the perpetrators generally allow leverage as high as 50 to 1, with automatic liquidation that can wipe out positions during sharp moves.
CME CEO Terry Duffy announced that the company would sue the CFTC, arguing that the regulator had misclassified the product. As The Wall Street Journal reported, CME’s complaint alleges that Kalshi’s perpetrators should have been classified as swaps, which would have subjected them to stricter Dodd-Frank rules.
Kalshi has already logged more than $5 billion in perp volume since launch, with shares of CME, Cboe and ICE falling post-approval as investors read the CFTC’s decision as a long-term competitive threat to the established exchanges.
This market response shows why CME’s objection rests as much on competitive logic as on consumer protection. Kalshi started as a platform where users can exchange event contracts, such as the chances of Fed rate cuts or who will win the election.
Adding regulated Bitcoin offenders draws Kalshi into the same retail derivatives screen that CME has spent decades building. The lawsuit is CME’s attempt to use the courts to slow that expansion before it becomes structural.
Wider recoil
The Futures Industry Association (FIA) and its Principal Traders Group told the CFTC that perpetual derivatives raise questions about trading and clearing risks, and urged the agency to establish clearer definitions and a formal regulatory process before approving more such products.
A bipartisan coalition of 41 attorneys general told the CFTC that contracts for sports-related events should remain under the authority of the state, arguing that platforms like Kalshi and Polymarket operate as unregulated sportsbooks.
The CFTC’s commentary on the prediction market includes the American Gaming Association, state gambling boards in Arizona, Illinois, Maryland and Michigan, the Indian Gaming Association, Major League Baseball and the NBA.
| Actor | Goal | Core objection | Bigger problem |
|---|---|---|---|
| CME | Kalshi BTCPERP | Should be treated as a swap, not a futures contract | Protecting the perimeter of the futures market |
| FIA / FIA PTG | Perpetual Derivatives | New trading and clearing risk | A clearer CFTC process is needed |
| 41 attorneys general | Contracts for sporting events | The state gaming authority must apply | Federal vs. State Control |
| Game groups/tribes | Prediction markets | Event contracts are similar to sports betting | Perimeter of gambling legislation |
| MLB/NBA | Sports contracts | Concerns about integrity and betting | Commercialization of sports risks |
| CFTC | State enforcement actions | The federal DCM authority must give priority to states | Who regulates event markets |
The CFTC proposed new event contract rules on June 10, with comment expected on July 27, and on June 12 the CFTC sued New Mexico to block state gambling enforcement against CFTC-registered contract markets, citing similar conflicts in Arizona, Connecticut, Illinois, New York, Minnesota, Rhode Island and Wisconsin.
The argument for CME’s derivatives classification, the attorneys general’s defense of the state gaming authority, the FIA’s litigation objections, and the sportsbook framing of the gaming industry all stem from different institutional interests while seeking the same expansion.
Platforms bundle tradable markets into categories that incumbents and regulators have kept separate for decades.
Convergence is already underway
Kalshi and Coinbase landed regulated crypto perpetrators, marking the first time such products were available to US investors through domestic regulated exchanges.
Polymarket’s website is advertising directly to offenders, with early access invitations now available.
Hyperliquid, which built its user base on perpetual crypto futures, has moved through HIP-4 to add outcome markets for off-chain events including US inflation data and Federal Reserve decisions, allowing users to trade prediction contracts alongside crypto derivatives in a single account.
Each platform independently followed the same underlying product logic, as perpetrators generate continuous leverage-driven volume, event contracts generate media-driven attention spikes, and a platform that hosts both captures both revenue streams.
Between May 17 and June 10, SpaceX’s pre-IPO perpetrators generated approximately $3.2 billion in volume and $390 million in open interest across eight exchanges, with Binance accounting for $2.1 billion.
These are synthetic instruments with no direct claim on underlying shares, but demand for tradable exposure to private company valuations produced $3.2 billion in volume in less than a month.
The list of assets that cannot become an underlying perpetrator is getting shorter.
Two possible outcomes
If the CFTC’s regulations hold, with courts rejecting the CME’s argument for exchange classification, federal preemption includes state gaming enforcement, and platforms continue to add cross-asset markets, the all-exchange model will accelerate.
Bitcoin is becoming the gateway collateral and risk asset for a wider range of retail derivatives products. The $5 billion early volume reported by Kalshi’s WSJ would, if continued at that pace, rise to nearly $90 billion annually for onshore perpetrators alone.
Prediction markets add derivatives depth, derivatives platforms bring event market engagement, and the line between a futures exchange, a sportsbook, and a crypto trading app collapses into a UX distinction.
| Scenario | What’s happening | Market implication |
|---|---|---|
| CFTC perimeter applies | Courts reject CME’s argument; federal preemption limits state gambling enforcement; platforms continue to add cross-asset markets | Scale of onshore Kalshi-style perpetrators; The early volume of $5 billion, if sustained, could reach nearly $90 billion annually |
| Incumbents are slowing their expansion | Injunction, remand, exchange classification or narrower rules for event contracts | Offshore locations continue to dominate the $61.7 billion global offender market; U.S. regulated offenders remain below the annual face value of $154 billion |
| Key question | Can one platform legally host BTC, inflation, elections, sports and private company exposure? | The winning platforms are the ones that survive the regulatory battle |
If incumbents succeed in slowing expansion through an injunction, a remand forcing Kalshi perpetrators into exchange classification, or a narrower event contract framework from the CFTC, platforms will absorb higher compliance costs, more geofencing, and slower product cycles.
Offshore locations continue to dominate global offender volume, which reached $61.7 trillion in 2025, up 29% from the previous year, while US-regulated onshore offenders remain below $154 billion annually.
Users already trade BTC, inflation, elections and sports results. The platforms that absorb the current legal and regulatory frictions will be the ones positioned to host it all, regardless of the compliance framework that remains in place.
CME’s lawsuit confirmed that the battle is already underway, and that established players in futures, gaming and state government have decided to fight it simultaneously.
