Chamath Palihapitiya said on the September 11, 2026 episode of the All-In podcast that a viral warning from an Anthropic safety researcher has turned the company's pre-IPO quiet period into a live disclosure crisis ahead of a potential $2.3 trillion IPO. The trigger was a Slack resignation note that spilled onto X, in which a departing Anthropic safety researcher told colleagues he believed there was more than a 10% chance AI could kill all humans, a message amplified by additional OpenAI and Anthropic researchers calling for an AI slowdown. A former Anthropic researcher repeated the warning to the BBC on September 13, 2026, saying staff were genuinely frightened for humanity's future. Palihapitiya likened the situation to Philip Morris concealing product dangers, and co-host David Sacks said Anthropic must either repudiate its own safety researchers or admit their fears, either outcome threatening the IPO. Palihapitiya pointed to precedents in which the SEC forced Alphabet to insert the full Playboy interview with Larry Page and Sergey Brin into its prospectus and made Slack explain a generic, positive CNBC comment he made as a board member. He said three factors will decide the IPO's fate: any amendment to the confidential draft S-1 that expands AI-safety risk factors or names the departures, whether leadership issues a formal repudiation that itself becomes a prospectus exhibit, and whether more frontier-lab staff go public with warnings.
