The approval of perpetual futures contracts in the US may expose traders to unforeseen tax and regulatory ambiguity if these products are ultimately classified as swaps rather than futures, warns CME Group Chairman and CEO Terry Duffy. This concern stems from the ongoing legal dispute between CME and the Commodity Futures Trading Commission (CFTC) over the regulator's approval of perpetual futures contracts. The outcome of this case could substantially influence the US approach to the rapidly expanding market of perpetual futures, particularly in terms of how the Internal Revenue Service (IRS) will tax these contracts. At the heart of the issue is whether perpetual futures should be legally categorized as futures or swaps, with Duffy arguing that they should be considered swaps due to the periodic funding payments exchanged between long and short positions, which aligns with the statutory definition of a swap under US law.

If perpetual contracts are deemed swaps, they would be subject to 'ordinary' taxation, as opposed to the blended tax treatment available for futures under Section 1256 of the US tax code. Given the novelty of perpetual futures, the IRS has yet to provide specific guidance on their tax treatment, leaving market participants uncertain about how to report their positions. Legal experts emphasize the complexity of the issue, noting that while perpetual futures structurally resemble swaps, they function economically like futures, making it a 'substance-over-form' question.

The broad definition of swaps and the recent Supreme Court decision to eliminate the Chevron doctrine, which reduces deference to agencies' interpretations of ambiguous statutes, contribute to the uncertainty. As a result, the classification and tax treatment of perpetual futures are likely to be decided through lengthy litigation, potentially involving the Supreme Court, and may require separate guidance from the IRS. Until clarity is achieved, large institutions face uncertainty regarding the reporting of trades involving perpetual futures, which could lead to significant tax implications.
