**[David Sacks States Anthropic IPO Must Be Paused Until "Whistleblower" Allegations Are Investigated]** Beating AI News Flash: David Sacks, Chairman of the U.S. President's Council of Advisors on Science and Technology, has stated that Anthropic's initial public offering (IPO) must clearly be paused until allegations from the "whistleblower" are thoroughly investigated. The "whistleblower" refers to Jacob Coxon, a former researcher at Anthropic. Coxon previously worked on pre-training research at OpenAI and joined Anthropic in July 2026, only to resign in September after approximately four months. He publicly posted warnings on X, claiming that many insiders at leading AI companies genuinely believe this technology could lead to human extinction within a decade. He accused both companies of irresponsibly racing toward self-improving superintelligence, effectively gambling with the lives of all humanity. Coxon left before his equity vested (companies typically begin vesting after six months), thereby forfeiting potential massive stock gains. This incident occurred as Anthropic had secretly filed for an IPO, with its valuation nearing $1 trillion. [Original Link]
