[Coinbase to Launch First Perpetual Stock Index Futures on June 8] According to the official blog, Coinbase announced it will launch its first perpetual stock index futures on June 8 under the CFTC regulatory framework. The offerings include four thematic contracts: AI10 Index, China 10 Index, Defense 10 Index, and Tech 100 Index. These contracts provide targeted thematic exposure, adopting a perpetual structure that uses a funding rate mechanism to closely link futures prices with the underlying indices. They can be traded 24/7 on a regulated U.S. futures exchange. As futures contracts, these products qualify for 60/40 tax treatment. The AI10 Index tracks the top 10 AI companies listed in the U.S., requiring at least 50% of their revenue to come from AI infrastructure, data, and applications. It is weighted by circulating market capitalization with a 15% cap per constituent and rebalanced quarterly.
