Anthropic has chosen Nasdaq for its October IPO, in the week OpenAI ruled one out

Anthropic has settled on Nasdaq for an October listing, according to a person familiar with the plans — the financial press's way of saying that a human we cannot name has told a reporter something a company would very much like us to believe. The venue is Nasdaq. The month is October. The source is a whisper. Meanwhile Sam Altman has ruled out an OpenAI IPO this year on safety grounds, a decision we noted at the time. So one safety-first lab stays private, the other safety-first lab gets a ticker, and both stay consistent by doing what they were always going to do.

The detail that turns this from a spreadsheet into a story is in the excerpt: the safety warning that has dominated the past fortnight came from a former Anthropic researcher who resigned over safety. That is the company's own ex-employee, saying the quiet part through a megaphone, and the corporate reply — choose an exchange, book a month, ring Business Insider — is about as eloquent as replies get. Nothing says 'we have taken your concerns about existential risk extremely seriously' quite like securing the venue with the best technology-listing brand and cracking on with the roadshow. From a competitor, you could wave the warning away. From an insider who walked out, it is the sort of alarm you are at least supposed to glance at.

And observe the choreography of the past fortnight: essays urging a slower pace on frontier development, Chinese state media branding those essays a Cold War strategy, California lawmakers demanding criminal penalties, Australia's assistant minister calling oversight 'alarming' — and now, an IPO calendar. Somewhere in the eventual prospectus sits a risk-factors section, and in it a paragraph about safety and public trust, drafted by lawyers who bill more per hour than most of us earn in a week. The risk factor is the pitch deck with a disclaimer stapled to the back. October, then.
