The Hyperliquid Policy Center (HPC) submitted its brief on September 9, 2026, in Case No. 1:26-cv-02157 before Judge Colleen Kollar-Kotelly of the U.S. District Court for the District of Columbia. CME Group filed its underlying lawsuit on June 18, 2026, challenging the CFTC's May 29 order that approved Kalshi's BTCPERP contract, a bitcoin perpetual futures product and the first of its kind to receive regulatory clearance in the United States. The May 29 order had two distinct components: it approved Kalshi's BTCPERP contract, and it issued a companion policy statement, published in the Federal Register on June 3, 2026, extending the right to list perpetual contracts to all registered Designated Contract Markets (DCMs), not just Kalshi. That second component is what gives the case its industry-wide significance, and both elements are under challenge in CME's suit. The CFTC filed its own motion to dismiss on September 2, calling the case "much ado about nothing" and disputing CME's legal standing to sue.

What CME Is Arguing, and Why HPC Disagrees

CME's lawsuit rests on the claim that perpetual contracts are legally swaps under the Dodd-Frank Act, not futures, because they carry no fixed delivery date.

If correct, that classification would route them to a different regulatory framework than the one the CFTC applied. The HPC's brief attacks this argument at the threshold level, raising two core legal arguments before the merits are even reached.

First, HPC argues CME cannot demonstrate a concrete injury sufficient to establish legal standing in federal court. Second, it argues CME's interests fall outside the scope of protections the Commodity Exchange Act is designed to provide, meaning CME is simply not the right party to bring this challenge.

Elizabeth Prelogar, who served as U.S. Solicitor General from 2021 to 2025 and is now at Cooley LLP, authored the brief on behalf of HPC. The brief states: "Once a titan of innovation, CME now advances a novel theory of standing under which an incumbent exchange is injured whenever its regulator permits a new product that it chooses not to offer." It also warns that a CME victory would set a broader chilling precedent: "If CME prevails, every product that the CFTC approves will invite litigation from incumbents who prefer the status quo."

The Data Gap at the Center of the Dispute

The volume figures embedded in the court record underscore what is actually at stake. Kalshi's BTCPERP contract cleared more than $100 million in notional volume on its first day of trading, June 3, 2026, and crossed roughly $1 billion in notional volume within its first week. CME, by contrast, had processed less than $6 million in perpetuals volume as of the time it filed suit. As HPC's brief argues, the disparity suggests CME's concern is less about active competitive injury and more about protecting its ability to define what derivatives look like under U.S. regulation.

Perpetual futures (commonly called "perps") are derivative contracts with no expiration date. Instead of settling on a fixed schedule, they use a funding rate mechanism, typically recalculated every eight hours, to keep the contract price close to the underlying spot market price. Traders can hold positions indefinitely.

Before Kalshi's launch, this product class was completely unavailable through regulated U.S. channels, despite generating $92.9 trillion in offshore notional trading volume in 2025 alone.

Why This Matters Outside the United States

The HPC's commercial interest in this case is direct. Hyperliquid is the dominant decentralized perpetual futures exchange globally. The platform accounted for roughly 44 percent of on-chain perp DEX trading volume as measured at mid-2026; broader estimates, depending on methodology, place its share of decentralized perpetual trading volume between 58 and 80 percent. Hyperliquid handled $633 billion in total trading volume during the first quarter of 2026 alone, with a cumulative lifetime volume exceeding $4.7 trillion. Its total value locked sits at approximately $5.9 billion.

Any U.S. legal precedent allowing incumbent exchanges to sue regulators over the approval of competing products would complicate Hyperliquid's own pathway toward regulated U.S. market access.

On July 6, 2026, South African exchange VALR, which holds a license from South Africa's FSCA and counts roughly 1.9 million registered users, launched more than 200 markets spanning crypto, equities, gold, oil, and foreign exchange, all built on Hyperliquid's on-chain infrastructure.

This is the first known case of a major regulated African exchange embedding a decentralized Layer-1 blockchain into its core execution stack. Traders across South Africa, Nigeria, and Kenya have historically relied on offshore platforms such as Binance and Bybit for derivatives access.

VALR's integration represents a shift toward regulated, domestically anchored alternatives. A successful CME challenge would put precisely that kind of innovation under legal cloud.

In India, the picture is forward-looking. SEBI has not established a crypto derivatives framework, and Indian traders access perpetual futures through offshore platforms, where gains are taxed at 30 percent under Section 115BBH and transactions are subject to a 1 percent tax deducted at source under Section 194S.

Regulators in New Delhi, and across emerging markets including Bangladesh, Pakistan, Nigeria, Ghana, and Ethiopia, are watching how the United States classifies and governs this product class.

A robust CFTC framework, upheld by courts, offers a working template for those markets. A ruling in CME's favor would signal that even in the world's most developed derivatives market, the regulatory ground for perpetual futures remains legally contested.

What Comes Next

CME's opposition brief is due October 2, 2026. No ruling timeline has been announced.

If the court grants either the CFTC's or HPC's dismissal arguments, the CFTC's May 29 approval framework for perpetual futures contracts stands. If the case proceeds to the merits, it will force a federal court to rule directly on whether perpetual contracts belong in the futures or swaps category under U.S. law. Critically, any such ruling would apply not only to Kalshi's BTCPERP contract but to the CFTC's companion policy statement as well, meaning the outcome could determine whether every registered DCM retains the right to list perpetual products. That is a question with consequences for every exchange, decentralized or otherwise, that trades these products.
