The AI sector is about to face its sternest test of market discipline yet. Anthropic, the artificial intelligence start-up founded by former OpenAI executives, has confirmed plans for a US stock market listing. The move comes as the company seeks to capitalise on the insatiable demand for generative AI tools, but it also raises the spectre of capital misallocation in a sector that has seen valuations balloon beyond reason.
For the City of London, this is yet another reminder of the allure of American capital markets. Anthropic’s decision to list in the US rather than London is a blow to the UK’s ambitions to become a tech listing hub. But let’s be honest: British investors are still nursing wounds from the float of Deliveroo and the collapse of tech darlings. The market for IPOs in London has been thin, with companies fleeing to New York where valuations are frothier and regulation less onerous.
Anthropic’s listing plans come at a time when the AI sector is awash with venture capital cash. The company has raised billions from investors including Google, Salesforce, and Spark Capital. Yet the fundamental question remains: how does one price a technology that is still unproven in its ability to generate consistent revenue? The hype cycle is in full swing, and central bankers are watching warily.
The Bank of England has been vocal about the risks of asset bubbles, and the AI frenzy fits the pattern. With interest rates still elevated, the cost of capital is high, and investors are chasing yield wherever they can find it. Anthropic’s float will be a litmus test for whether the market can distinguish between genuine innovation and speculative fever.
Gilt yields have been volatile this year, reflecting uncertainty about the economic outlook. A successful Anthropic IPO could provide a much-needed boost to risk appetite, but it could also exacerbate the divergence between the haves and have-nots in the tech sector. Companies with strong balance sheets and clear revenue paths will thrive, while those burning cash without a viable business model will face the harsh judgement of the market.
The Treasury will be watching closely. The Chancellor has been keen to promote the UK as a destination for tech listings, but the reality is that the regulatory environment and investor base are more favourable across the Atlantic. Anthropic’s decision is a pragmatic one, driven by the desire to maximise valuation and liquidity. It is also a rebuke to those who believe that London can compete with New York for high-growth tech floats.
As an analyst, I see this as a positive step for Anthropic. The discipline of public markets will force the company to focus on profitability rather than just growth. But the broader implications for the sector are concerning. The AI arms race is sucking up capital at a prodigious rate, and much of it will be wasted. Investors would do well to remember the dot-com bubble: the companies that survived were those with genuine competitive advantages, not just good PR.
In the meantime, the UK must grapple with its own fiscal realities. Inflation is still above target, and the government’s borrowing costs remain elevated. The last thing the economy needs is another speculative bubble that bursts with little tangible benefit. But markets will do what markets do, and Anthropic’s float will go ahead. The only question is whether it will be a catalyst for further excess or a sobering lesson in valuation discipline.
