The options platform, built on Hyperliquid, stated that of its $640 million notional volume since going live in June, more than 80% came from S&P 500 options. Open interest for S&P 500 options is about $47 million, out of a total of $49 million. Founder Jake Sylvestre noted that traders are gravitating to blockchains for exposure to traditional markets, especially outside conventional exchange hours.
