OpenAI rules out 2026 listing as Altman cites safety concerns

Anthropic, the developer of the Claude AI models, closed the three months to the end of September with revenue of $16.8bn (£12.7bn), up 45%, according to the BBC. The broadcaster said it understands the figures were revealed as the company, led by chief executive Dario Amodei, briefed prospective investors on Wednesday at its headquarters in San Francisco.

Anthropic is laying the groundwork for what the BBC said is expected to be a blockbuster share sale by the end of the year. An Anthropic spokesperson declined to comment.

Anthropic’s revenue has risen in successive quarters this year, from $4.7bn in the first three months to $11.6bn in the following period, the BBC reported.

The figures — Anthropic’s and those of rival OpenAI — offer an important gauge of the AI industry’s growth and its ability to finance the infrastructure needed to develop the technology, according to the BBC.

OpenAI, the ChatGPT developer, is also eyeing a bumper stock market listing that the BBC said is expected to value the firm at more than $1tn.

OpenAI chief executive Sam Altman said in September that the company will not go public this year as it addresses concerns about the technology’s safety, the BBC reported.

The revenue disclosures come as some technology stocks, including companies that make the chips and other hardware that power data centres, have come under pressure over concerns about the large amounts of money being spent on AI infrastructure, the BBC reported.
