Anthropic IPO Filing Is Followed by a 159% Rise in Perpetual Volume

Anthropic’s public filing of an IPO registration statement on Oct. 26 was followed in less than an hour by a 159% jump in 24-hour trading volume for prelisting perpetual contracts tied to the AI company. The contracts reflect trading interest ahead of a proposed stock listing, rather than trades in Anthropic shares on Nasdaq. Binance-related contracts posted a larger venue-specific increase: their 24-hour volume rose 233% to $35.2 million. Open interest, the number of positions that remain open, increased 6.8%. The 159% figure describes the broader set of Anthropic prelisting contracts, while the Binance figure covers a venue-specific group.
