Hypercall will open what it calls the world’s first options market linked to Anthropic at 8 a.m. U.S. Eastern Time on November 9. The 24/7 market will offer synthetic, cash-settled contracts tied to the anticipated pre-IPO share price of the artificial-intelligence developer, without conferring ownership, voting rights or allocations of Anthropic shares. The Hyperliquid-based platform will exclude U.S. users and use existing Anthropic-related perpetual contracts on Hyperliquid to help market makers hedge option-writing risk. Hypercall has previously listed options tied to SpaceX, the S&P 500, BTC and ETH, recording approximately $536 million in notional options volume in September. Separately, Polymarket odds for Anthropic going public in November fell from roughly 88% on Tuesday to about 51% on Thursday.
