Hypercall to launch first Anthropic-linked pre-IPO options market, trading expected Monday

Hypercall, an onchain options platform built on Hyperliquid, expects Anthropic-linked options trading to begin Monday, available around the clock in select non-US jurisdictions, founder Jake Sylvestre and Dan Edlebeck told The Block. The synthetic, cash-settled contracts confer no shares or voting rights; payouts depend on strike and reference prices at expiry. Existing Anthropic perps let market makers hedge. Hypercall reported $536 million September options notional. The launch comes as prediction markets cut odds of a November IPO—Polymarket fell from 88% to 51%—and the Nasdaq dropped about 6% on AI spending concerns.
