TL;DR

Anthropic, the company behind the Claude AI model, is considering an initial public offering as early as October 2026. The company is in preliminary discussions with Goldman Sachs, JPMorgan, and Morgan Stanley, with reports suggesting a listing could raise more than $60 billion (approximately £48 billion).

From startup to potential public company in five years

Founded in 2021 by former OpenAI staff including CEO Dario Amodei, Anthropic has grown at a pace that would have seemed improbable even by Silicon Valley standards. The company’s most recent funding round in February, co-led by Abu Dhabi’s MGX, valued it at $380 billion (approximately £304 billion) — a figure that places it among the most valuable private companies in history.

Anthropic has secured partnerships with Google, Amazon, Microsoft, and Nvidia, and has pledged $50 billion (approximately £40 billion) toward US data centre construction. The scale of that infrastructure commitment suggests the company is planning for sustained growth rather than a quick exit.

The IPO race

Anthropic and OpenAI appear to be in a parallel sprint toward public markets. Both companies have raised enormous sums privately, but an IPO would provide liquidity for early investors and employees while establishing a public market valuation that either validates or challenges current private pricing.

The timing is notable. AI companies have attracted record private investment over the past three years, but public market appetite for AI stocks has been more selective. Investors will be looking for evidence of durable revenue, not just technological promise.

A complicated week

The potential IPO news arrives during a turbulent period for Anthropic. On Thursday, a US federal judge blocked the Trump administration from implementing a supply chain risk designation against the company — a move that Anthropic argued could have severely damaged its business. That legal victory removes one significant obstacle to a public listing, where regulatory risk would feature prominently in any prospectus.

Looking forward

For UK investors and AI companies watching the market, an Anthropic IPO would be a bellwether. The listing price relative to its $380 billion private valuation will signal whether public markets agree with venture capital’s assessment of AI’s commercial potential — or whether a correction is overdue.
