Kalshi's Bitcoin Perpetual Contract Creates Tax Treatment Uncertainty

The Commodity Futures Trading Commission (CFTC) approved Kalshi's Bitcoin perpetual contract as a futures contract, but this approval has created uncertainty about its tax treatment.

If treated as a regulated futures contract under Internal Revenue Code §1256, individual traders would generally receive annual mark-to-market treatment and the familiar 60% long-term and 40% short-term capital gain allocation regardless of holding period.

However, if it's instead treated as a swap, the taxpayer may face the notional principal contract rules of Treas. Reg. §1.446-3, which could result in ordinary income treatment.

The Chicago Mercantile Exchange (CME) is challenging the CFTC's approval of Kalshi's Bitcoin perpetual contracts in court, arguing that they are swaps rather than futures under §1a(47) of the Commodity Exchange Act.
