The approval of perpetual futures contracts in the US could expose traders to unforeseen tax and regulatory complexities if these products are ultimately deemed to be swaps rather than futures, a concern voiced by CME Group Chairman and CEO Terry Duffy. In an interview, Duffy highlighted the ambiguity surrounding the tax implications for US participants, stemming from the periodic funding payments exchanged between long and short positions in perpetual contracts, which he believes align more closely with the legal definition of swaps under US law. Unlike traditional futures, perpetual contracts do not expire and involve recurring funding payments to maintain the derivative's price in line with the underlying asset, a mechanism Duffy argues satisfies the statutory definition of a swap. The main issue arises from the potential mismatch in designation, as institutional traders could face blended tax treatment under Section 1256 of the US tax code if perpetual contracts are classified as futures, but would be taxed under ordinary taxation if deemed swaps.

Given the novelty of perpetual futures, the IRS has not provided specific guidance on their tax treatment, leaving market participants uncertain about how to report these positions. Legal experts, such as Rustin Diehl and Jason Gottlieb, note that the challenge lies in the complexity of distinguishing between the form and substance of perpetual futures, with the definition of swaps being extremely broad and open to interpretation. The outcome of the ongoing legal battle between CME and the CFTC, awaiting a federal court decision, could significantly influence the US approach to perpetual futures and may lead to further litigation and potential tax implications for traders.
