Artificial intelligence (AI) giant Anthropic saw its revenue surge by 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 as it briefed prospective investors on Wednesday at its headquarters in San Francisco as it lays 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 firms 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.
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 reportedly said that it made a profit for the second quarter in a row.
