Anthropic files confidentially for US IPO, edging out OpenAI
TL;DR:
- Anthropic has submitted confidential paperwork to the US Securities and Exchange Commission for an initial public offering this year, with the share price and offer size still to be set.
- The Claude developer was recently valued by private investors at more than $965bn (£717bn), putting it ahead of OpenAI’s $852bn.
- A listing would become an early test of whether public markets will support the soaring valuations attached to frontier AI companies.
The company behind the Claude chatbot said on Monday it had begun the process to go public, becoming the first of the leading AI labs to move concretely towards a market debut. Confidential filing lets a company prepare its offering while keeping detailed financials away from rivals until closer to launch.
Why the timing matters
Anthropic’s move arrives alongside reported IPO preparations at OpenAI and a record-breaking listing push from Elon Musk’s SpaceX, setting up what analysts describe as the largest cluster of pre-IPO capital ever brought to market at once. Reuters reports that the rush reflects a calculation that whoever lists first gets to define how investors value generative AI — and absorbs the scrutiny that comes with publishing audited frontier-AI accounts.
Unusually for the sector, Anthropic has told investors it expects to turn a profit in the first half of this year; neither OpenAI nor SpaceX is currently profitable. That distinction could matter to UK institutional investors and pension funds weighing exposure to AI through US listings, particularly after recent volatility in AI-linked equities.
The filing also lands while Anthropic remains in an unresolved legal dispute with the US Department of Defense over contract terms governing how its models may be used — a reminder that governance questions travel with these companies into public ownership.
Looking forward
A near-trillion-dollar debut would place Anthropic among the largest companies on US markets and hand investors a concrete yardstick for the AI sector. For UK readers, it sharpens the central question hanging over the AI boom: whether disclosed revenues and margins can justify valuations built largely on expectations of future growth. The answer will shape sentiment well beyond Wall Street.
