Anthropic has filed for an initial public offering in the US, moving the maker of Claude closer to a potential stock market debut and setting up a major test for investor confidence in the artificial intelligence sector.
The company’s shares are expected to be listed on the technology-focused Nasdaq Composite Index under the ticker symbol “ANT”. The IPO could take place as early as November.
In its filing with the Securities and Exchange Commission, Anthropic said the spread of AI through the global economy represented “one of the largest opportunities in history to improve how humans live and work”.
The filing showed rapid growth in revenue. Anthropic generated $16.3 billion in the first half of 2026, compared with $1.2 billion during the same period last year.
However, the company has yet to make a profit. It reported a net loss of $80.7 billion for the first six months of 2026, more than six times the nearly $13 billion loss recorded in the first two quarters of 2025.
The share sale will also be closely watched across the wider AI industry, including by data centre builders, chipmakers and other companies supplying the infrastructure used to run AI services.
Anthropic IPO comes amid safety concerns
Anthropic submitted a confidential IPO filing in June, shortly before rival OpenAI did the same. Both companies are pressing ahead with plans to enter public markets despite concerns about the risks posed by increasingly powerful AI systems.
Reports of AI agents acting unpredictably have fuelled fears that the technology could escape human control and be used to carry out cyberattacks. In September, Anthropic chief executive Dario Amodei called for a slowdown in AI development after a former researcher at the company said there was a 10 per cent chance the technology could wipe out humanity within the next decade.
Mr Amodei said the pace of technological progress should be treated as a warning sign, while also arguing for the continued development of AI.
Analysts at investment advisory firm Lightshed said Anthropic could become “the most valuable company in the world” but could also end up in bankruptcy.
They said the company needed capital while competing with other AI businesses for the same investors, leaving potential shareholders little time to assess what they were being asked to own.
