Hypercall to Launch Pre-IPO Anthropic Options, Trading Opens Next Monday

November 6 — According to The Block, 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 options are synthetic, cash-settled derivatives; traders will not hold actual Anthropic shares or gain voting rights, and the contracts will trade around the clock but will not be open to US users. Hypercall said existing Anthropic-related perpetual contracts on Hyperliquid can let market makers hedge the risk of writing options. The platform previously listed options tied to SpaceX, the S&P 500, BTC and ETH, with about $536 million in notional options volume in September. Separately, according to reports, the probability on Polymarket of Anthropic going public in November has fallen from about 88% on Tuesday to a low of about 51% on Thursday.
