CME Duffy warns: U.S. perpetual futures face tax danger zone

Dispute over the definition of perpetual contracts: Tax hazards may ignite industry shocks

A hidden legal battle over the definition of perpetual contracts may reopen tax issues that many traders and platforms have long ignored. CME Group CEO Teri Duffy warned on Wednesday that if the dispute over whether these contracts are swaps or traditional futures is not resolved, it could eventually drag the IRS into it. This time point is crucial-the volume of crypto derivatives trading in the United States is growing, and any mandatory reclassification will affect all trading platforms that offer perpetual contracts to U.S. users.

Duffy's comments come as Washington is slowly moving forward with broader crypto legislation. Although most discussions focus on spot market regulation and stablecoins, the tax treatment of derivatives remains a loophole that could catch the industry off guard. If it is ultimately ruled that perpetual contracts are swaps rather than futures, it will change the way earnings are taxed and may even bring them into a completely different system of rules. This means changes in fair value accounting treatment rules, adjustments to holding period rules, and may even create retrospective tax obligations based on the intensity of the IRS's actions.

Swap or futures: An unresolved qualitative problem

Perpetual contracts are in a legal gray area. They have no expiration dates and rely on capital rates to anchor spot prices, a structure that blurs the line between futures and swaps. Traditional futures are traded on exchanges, centrally cleared and have fixed maturity dates, while swap contracts are usually negotiated bilaterally and subject to different regulatory frameworks. The mechanism of crypto perpetual contracts traded on offshore platforms such as Binance and Bybit is closer to a continuously rolling swap contract than traditional CME futures products.

U.S. courts are currently discussing how to define these tools in a separate lawsuit. Duffy warned that the court ruling in the case could provide the IRS with a basis to tax perpetual contracts as swaps-even if the Commodity Futures Trading Commission treats them as futures for market regulatory purposes. The mismatch between the Commodity Futures Trading Commission classification and the judicial level swap characterization will create compliance chaos for trading platforms and brokers serving U.S. residents. This is precisely the regulatory fragmentation issue that banks are taking advantage of when fighting for the U.S. crypto legislative structure, and the legislative wrangling over the crypto market structure has fully exposed this.

How the IRS intervenes

The tax differences between swaps and futures are by no means superficial. Futures contracts are subject to the 60/40 rule stipulated in Article 1256 of the Tax Law, which means that 60% of the income is taxed on long-term capital gains regardless of the length of the holding period. Swap contracts are subject to general income tax or standard capital gains tax depending on the circumstances, and often face different intertemporal arbitrage and false selling analyses. For high-frequency traders and market makers who trade millions of dollars in perpetual contracts every month, being classified as swaps will have an immediate financial impact.

There is currently no indication that the IRS is actively preparing to reclassify perpetual contracts. But regulators often follow judicial guidance, and the legal profession remains divided on this. Relevant independent experts confirmed that this issue is far from settled. If a federal court determines that perpetual contracts are essentially swaps, the IRS could issue guidance and even investigate trading platforms that used to treat such instruments as futures declarations. For traders, this may mean amending returns and paying interest penalties-even if the transaction is executed in good faith.

Broader regulatory fog

The tax issue of perpetual contracts is just part of a larger picture: scattered legal decisions are reshaping the way the U.S. crypto market operates, without a comprehensive framework. Institutional participants that have entered the realm of tokenization and on-chain clearing are paying close attention to the definition of derivatives as much as they are focusing on spot market rules. Changes in the tax status of perpetual contracts will directly affect hedging strategies and the cost of capital for market-making companies.

Duffy's CME is not a neutral bystander. The exchange has good reasons to ensure that its traditional futures products are not undermined by offshore perpetual contracts that may enjoy looser tax assumptions. That doesn't mean his warnings were wrong, but it does add a competitive dimension to the regulatory debate. Large crypto trading platforms serving U.S. clients are already coping with tensions between the U.S. Securities and Exchange Commission and the Commodity Futures Trading Commission. Adding the IRS as a front would force the industry to more severely examine whether perpetual contracts can survive in their current form in the United States.

What remains uncertain is how quickly the legal trigger mechanism will arrive. The lawsuit mentioned by Duffy is still in judicial proceedings and any final ruling could face appeal. Market participants should not expect changes overnight, but neither should they assume that the status quo will last forever. Tax uncertainty of this scale is just preventing the return of funds from large institutions to the United States. The longer the classification issue remains unresolved, the higher the risk will be borne by each perpetual contract trading counter facing the U.S. market.
