Odaily News: BTC IV at 38%, ETH IV at 53%. ETH Skew shows divergence, with the mid-to-long-term maintaining +2 to +4, indicating strong institutional bullish consensus. The short-term skew has sharply deteriorated to -8 to -12 due to CPI exceeding expectations and Powell's resignation, leading to a surge in short-term hedging demand. BTC/ETH GEX has shifted from a long Gamma, steady bull market strategy to short Gamma, widening short-term volatility and making it difficult for IV to drop significantly.

In block trades, 2,181.8 lots (worth $176 million) of BTC 5/15 expiry $82K Calls were traded; 11,026 lots (worth $24.97 million) of ETH June $2,100 Puts were traded.Gate has launched an exclusive incentive plan for options VIPs.

According to Dark Web Informer, the decentralized prediction market platform Polymarket is suspected of having been hacked. The threat actor “xorcat” posted over 300,000 data records and a corresponding exploit toolkit on a well-known cybercrime forum. The data extraction occurred on April 27, 2026. Reportedly, the attacker extracted data via an undisclosed API endpoint, pagination bypasses, and misconfigured CORS settings in Polymarket Gamma and the CLOB API. The leaked data includes: - Full personal information for 10,000 users (including names, proxy wallets, and base addresses); - 4,111 comments; - 1,000 moderation reports (including 58 ETH addresses and administrator authentication address identifiers); - Metadata for 48,536 Gamma markets; - Constant-product market maker addresses for over 250,000 active CLOB markets; and - Social graph data for 9,000 followers. The toolkit contains proof-of-concept code for multiple vulnerabilities, including CVE-2025-62718 (Axios NO_PROXY bypass, CVSS 9.9, enabling server-side request forgery), CVE-2024-51479 (Next.js middleware authentication bypass, CVSS 7.5), and the aforementioned CORS misconfigurations.
