Roaring Kitty X Account Hijack — RKC Memecoin Pump & Dump

Timeline: On May 11, 2026 around 21:13 UTC, Keith Gill's verified X account (Roaring Kitty), dormant for 16 months, suddenly published the contract address of a new Solana memecoin RKC deployed on Pump.fun. Within 30 minutes, market cap pumped to between $5.97M and $12M (consensus sources cite $11-12M, while BeInCrypto and Yahoo reported a $5.97M peak). The posts were then deleted, and RKC crashed over 90% within two hours. Lookonchain traced the developer's 10-wallet cluster: 39.52% of total supply acquired for ~$1,950 in 20 SOL pre-promotion, then dumped during the pump for 5,071 SOL plus 1,209 SOL in Pump.fun creator fees (~$611K total profit). Over 80 retail wallets lost a combined ~$2.86M. GameStop stock briefly spiked 12-13% intraday on the social signal before erasing gains. As of May 16, Keith Gill has neither confirmed nor denied the account hijack publicly. Speculation about Kevin Gill (brother) is unverified.
