The Hyperliquid Phantom CFTC filing, submitted on 9 July 2026, argues that decentralised trading software developers and non-custodial wallet interfaces should face categorically different regulatory treatment from traditional brokers, exchanges, and clearinghouses.
The joint comment letter, addressed to CFTC Secretary Christopher Kirkpatrick and signed by the Hyperliquid Policy Center (HPC) and Phantom, responds to a fintech Request for Information (RFI) the Commodity Futures Trading Commission (CFTC) published at 91 Fed. Reg. 36774 on 18 June 2026. The RFI was issued under Executive Order 14405, titled ‘Integrating Financial Technology Innovation Into Regulatory Frameworks’, with a 21-day public comment window.
The core argument: writing software is not the same as running a financial services business. The filing contends that onchain markets rest on a fundamentally different custody model, one where users retain control of their own assets rather than surrendering them to an intermediary, and that forcing code-based infrastructure into legacy registration frameworks misreads how the technology actually works.
What the Hyperliquid Phantom CFTC Filing Actually Proposes
The letter sets out a three-part roadmap. First, developers of onchain trading software should not be required to register as exchanges or clearinghouses solely because they deploy decentralised infrastructure. Second, non-custodial wallet interfaces, Phantom explicitly among them, should not be classified as introducing brokers. Third, firms already holding CFTC registration should be free to integrate blockchain-based settlement and clearing without additional regulatory friction.
The second point carries existing regulatory backing. In March 2026, the CFTC issued Phantom no-action relief, confirming that a non-custodial interface providing only technical access to regulated markets does not trigger introducing-broker registration requirements, according to Phantom’s official blog. The July comment letter now asks the CFTC to codify that position into durable rulemaking rather than leaving it to relief letters.
The filing also notes that Phantom integrates Hyperliquid on its interface, though that functionality is not currently available to U.S. users, a detail that underscores the practical stakes for both organisations if the regulatory position hardens against them.
The CFTC’s FinTech RFI specifically asked which existing regulations unduly impede fintech firms from partnering with federally regulated institutions, and which application processes could be streamlined. HPC and Phantom are among the respondents arguing the answer lies in creating a separate lane for decentralised infrastructure rather than carving exemptions from rules designed for centralised market operators.
The CME Lawsuit Sitting Beneath This Debate
The filing lands in the middle of a live legal dispute that makes the CFTC’s definitional choices materially consequential. Reuters reports that CME Group filed suit in Washington D.C. federal court on 18 June 2026, seeking to void the CFTC’s 29 May approval allowing Kalshi to list a bitcoin perpetual future, as well as a policy statement opening a regulated path for similar contracts at other exchanges.
CME’s argument is that perpetual contracts are swaps under the Dodd-Frank Act, not futures, and therefore required a different regulatory process before approval. The Defiant reports that CME Group CEO Terrence Duffy disclosed the lawsuit plan during a CNBC Fast Money interview, stating the exchange had spent eight months preparing the legal challenge with its board before filing.
Kalshi’s perpetual contracts crossed $1 billion in trading volume across more than a dozen contracts within one week of launch, according to Dechert’s legal analysis of the dispute. Since then, Kalshi has extended its perpetual listings beyond bitcoin to include Ethereum, XRP, and Hyperliquid contracts. Coinbase has also secured a regulated route to offer certain crypto perpetual futures through infrastructure connected to Deribit.
HPC founder Jake Chervinsky has publicly described CME’s lawsuit as a serious mistake, accusing the exchange of using litigation to block new competitors. One day after CME filed, the CFTC and the Securities and Exchange Commission (SEC) published their joint RFI, which specifically asked whether the legal definition of swaps should be updated to cover crypto perpetual contracts.
The sequencing matters. If CME prevails and perpetuals are reclassified as swaps, the entire regulatory architecture that HPC and Phantom are asking the CFTC to build around onchain derivatives trading would need to be redesigned before it has been written. The CFTC’s response to the comment letters, expected after the 21-day window closes, will indicate which direction the agency is leaning before that question is resolved in court.
