Hypercall, an on-chain options platform built on Hyperliquid, will launch a pre-IPO options market linked to Anthropic, with trading expected to begin next Monday. The synthetic, cash-settled derivatives do not grant holders actual Anthropic shares or voting rights. Contracts will trade around the clock but remain unavailable to US users. The platform leverages existing Anthropic-related perpetual contracts on Hyperliquid to enable market makers to hedge option-writing risk. Hypercall 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 dropped from roughly 88% on Tuesday to a low of about 51% on Thursday.
