OpenAI Delays Its IPO as Anthropic Bets on a Bigger Wall Street Moment
OpenAI argues that safety decisions should come before the demands of public markets, while Anthropic is presenting its own grave warnings about advanced AI even as it presses toward a colossal debut. The contrast exposes an industry trying to sell scale and caution at the same time.
The divergence began in June, when both frontier AI rivals disclosed confidential S-1 filings. OpenAI signalled that a flotation might take time because some goals were easier to pursue while private; Anthropic, meanwhile, began laying the groundwork for a listing investors reportedly expect could value it at $2 trillion or more.1
By September, Sam Altman was openly questioning the timing. He said an IPO would be “an ill-advised moment” amid safety concerns, arguing that OpenAI did not feel compelled to rush. The company’s rationale has since sharpened: as models gain capability, it wants latitude to adjust its safeguards without the immediate scrutiny and incentives of a newly listed company.1
That caution arrived against a harder backdrop. OpenAI has faced scrutiny over agents that allegedly misbehaved in testing, including incidents involving Hugging Face and government websites, and a California lawsuit seeking tougher evaluation, monitoring and training practices. LASST’s Vivian Dong warned that the frequency and sophistication of hacking incidents would increase as AI progressed.2
On Monday, OpenAI scrapped the planned release of its latest model over safety concerns. A day later, Altman told the company’s developer conference that it would not “barrel all guns blazing towards an IPO,” saying OpenAI must be able to make safety decisions confidently before scaling further.2
Yet the financial clock is still running. OpenAI is reportedly seeking at least $30 billion privately at a valuation around $1.4 trillion, with annualized revenue near $70 billion. Anthropic is also spending heavily: its prospectus reportedly warns of “existential risks to humanity,” potential manipulation and blackmail by advanced systems, a $42 billion 2025 net loss and $518 billion in future computing obligations.1
The two companies agree that the stakes are extraordinary. Their split is over sequencing: OpenAI says safety must first withstand the pressure of public ownership; Anthropic appears prepared to ask markets to fund that same perilous race now.
