Artificial intelligence (AI) giant Anthropic saw its revenue jump 45% to $16.8bn (£12.7bn) in the three months to the end of September, the BBC understands.
The figures were reportedly revealed by the Claude developer when it informed potential investors on Wednesday at its headquarters in San Francisco that it is laying the groundwork for a stock market listing, which is expected to take place before the end of the year.
It comes as some tech stocks, including companies that make the chips and other hardware that power data centers, have come under pressure over concerns about the large sums of money being spent on AI infrastructure.
An Anthropic spokesman declined to comment.
Anthropic’s revenue has risen in successive quarters this year, from $4.7bn in the first three months to $11.6bn the following period.
The company also said it made a profit for the second quarter in a row.
Its revenue figures, along with those of rival OpenAI, provide an important gauge of the AI industry’s growth and ability to finance the infrastructure needed to develop the technology.
Shares in several US technology companies fell on Wednesday amid concerns about investment in AI.
Shares in chip makers – including AMD, Nvidia and Intel – fell sharply.
In Asia, shares of Japanese tech investment firm Softbank fell 9% on Thursday morning. South Korean semiconductor giants were also down, with Samsung falling 8.4% and SK Hynix down more than 6%.
South Korea’s tech-heavy Kospi index was 7.6% lower in morning trade.
The omissions come after comments by Hock Tan, the chief executive of US tech maker Broadcom, about AI spending.
