The San Francisco-based company was founded in 2021 by former OpenAI researchers led by chief executive Dario Amodei and his sister Daniela, now its president, with AI safety as its focus.
The listing comes amid growing nervousness among investors about the huge sums being poured into AI.
Revenue reached US$17 billion in the third quarter, up from US$1.4 billion a year earlier, though sales growth slowed from previous quarters amid fierce competition from ChatGPT-maker OpenAI and cheaper models.
The company, whose stock market debut is seen as a gauge of how long the AI spending boom lifting the US economy can last, said in an amended filing that its net loss reached US$23.3 billion in the July-September period.
The loss stemmed mostly from non-cash accounting charges linked to the company’s rising valuation, the filing showed.
Anthropic also posted an operating loss of US$567 million in the third quarter as it paid more for short-term computing capacity.
The filing said the company has committed to spend about US$895 billion, mostly on computing power, with US$70 billion of that due before September 2027.
The IPO will be a major test of the market’s faith in the AI boom, with the pool of potential investors set to widen as retail traders get their first chance to buy shares directly in a standalone AI giant.
According to several media outlets, the five-year-old company plans to raise around US$100 billion in its initial public offering, at a valuation of between US$1.5 trillion and US$2 trillion.
That would surpass the record set in June by SpaceX, which raised US$86 billion. (AFP)
