Anthropic quarterly revenue reportedly jumps 45% to $16.8bn before IPO

Anthropic, the company behind the Claude models, reportedly saw revenue climb 45% to $16.8bn in the three months ending in September. The numbers were said to have been shared with prospective investors on Wednesday, 14 October 2026, at the company's San Francisco headquarters. An Anthropic spokesperson declined to comment.

The briefing is part of the groundwork for a large share sale that is expected before the end of the year. Anthropic's revenue has grown every quarter in 2026, rising from $4.7bn in the first quarter to $11.6bn in the second before the latest jump.

Markets uneasy over AI spending

The figures emerged as investors grow nervous about the scale of spending on AI infrastructure. In the US on 14 October, shares in chipmakers including AMD, Nvidia and Intel fell sharply. On the morning of 15 October in Asia, SoftBank dropped 9%, Samsung lost 8.4% and SK Hynix slid more than 6%, while South Korea's tech-heavy Kospi index was down 7.6%.

The sell-off followed comments by Broadcom chief executive Hock Tan at a conference in Singapore on 12 October. Tan argued that many investors lack real understanding of the sector and have built extreme expectations, likening the situation to a casino.

The race with OpenAI

Revenue figures from Anthropic and its rival OpenAI are closely watched as a measure of how fast the AI industry is growing and whether it can fund the data centres the technology requires. OpenAI, the maker of ChatGPT, is also eyeing a listing expected to value it above $1tn, but chief executive Sam Altman said in September that the company would not go public this year while it works through safety concerns.

Anthropic has likewise been outspoken about AI risks, with chief executive Dario Amodei urging a slower pace of development. Meanwhile the company keeps expanding internationally and opened a new office in Singapore on 14 October.
