CME CEO Terry Duffy said Thursday that an overlooked tax risk is looming over perpetual futures contracts in the U.S. [1].

The issue centers on whether these financial instruments are legally classified as swaps or futures. Because the Internal Revenue Service applies different tax treatments to each category, a final legal determination could fundamentally change the tax obligations for market participants.

Duffy said a court battle over whether perpetual futures are swaps or futures could eventually affect how the IRS taxes the contracts [1]. The distinction is critical for institutional and retail traders who rely on predictable tax accounting to manage their portfolios.

Perpetual futures are a popular derivative in digital asset markets, allowing traders to hold positions indefinitely without an expiration date. However, the regulatory framework in the U.S. has struggled to keep pace with these instruments, creating a gap in legal clarity.

Independent legal experts said the issue remains unresolved [1]. This lack of consensus means that traders may be operating under tax assumptions that could be overturned by a future court ruling or IRS guidance.

If the contracts are classified as swaps, they may be subject to different reporting requirements and tax rates than if they are viewed as traditional futures. Such a shift would likely trigger widespread audits or the need for retroactive tax adjustments across the industry.

A court battle over whether perpetual futures are swaps or futures could eventually affect how the IRS taxes the contracts.

The tension between the rapid adoption of crypto-native derivatives and legacy U.S. tax law creates significant systemic risk. If the IRS determines that perpetual futures have been misclassified, it could lead to massive unexpected tax liabilities for investors and a chilling effect on the growth of regulated U.S. derivatives markets.
