Anthropic reported revenue of $16.8 billion ($12.7 billion) for the three months to the end of September, a 45 per cent increase on the previous period. The figures, disclosed by the developer of Claude during a briefing for potential investors on Wednesday, were met with silence from Anthropic’s spokesperson, who declined to comment.

The company’s revenue has grown quarter on quarter throughout the year, rising from $4.7 billion in the first quarter to $11.6 billion in the latest period. The company is also understood to have made a profit for the second consecutive quarter. Anthropic is laying the groundwork for a public listing, which is expected before the end of the year.

On Wednesday, shares in some US technology companies fell as investors expressed concern over investment in artificial intelligence. Shares in chipmakers, including AMD, Nvidia and Intel, dropped significantly. The decline followed comments from Hock Tan, the chief executive of American technology company Broadcom, regarding spending on artificial intelligence.

Tan stated on Monday at a conference in Singapore that many investors were 'clueless' and that they had set 'extreme expectations', only to discover that the reality was 'like being in a casino'.

Alongside Anthropic, other companies in the artificial intelligence sector are considering a public listing.

The developer of ChatGPT is also targeting a major public listing, which could value the company at over $1 trillion.

The chief executive of Anthropic, Dario Amodei, has called for a slowdown in the pace of development. The company opened an office in Singapore on Wednesday.
