The new investment, which was led by investors including Greenoaks Capital, Sequoia Capital, Altimeter Capital and Dragoneer Investment Group, boosted Anthropic’s value to nearly two and a half times its previous valuation of US$380b about three months ago.

The funding underlined the company’s success in developing AI technology that excels in writing software code. Since Anthropic improved its AI coding technology in November, hundreds of businesses have signed up to pay for the software. The company said its “revenue run rate”, which is its expected revenue for the year based on its current performance, crossed US$47b this month.

Anthropic’s trajectory stands out, even amid a heated frenzy over AI. Just 62 days ago, OpenAI – which had kicked off the AI boom with its release of the ChatGPT bot in 2022 – announced it had raised US$122b in a funding round that put its value at US$730b, a number it took roughly a decade to achieve. Anthropic, founded in 2021, has surpassed that in half the time.

The company’s momentum has gathered steam in recent months as chief executive Dario Amodei has spoken out about the potential dangers of AI and called for regulation of the technology. That led to a bitter fight with the Pentagon over how AI should be used in warfare, among other public imbroglios.

Anthropic’s rise only adds to its contest with OpenAI and Elon Musk’s SpaceX as the private companies race to go public.
