London's IPO Drought Deepens as Britain's Startups Look Elsewhere to Go Public

London was once one of the world's great places to take a company public. In 2026, that reputation is under real strain, as a prolonged drought in new stock market listings leaves British startups and their backers searching for a way out.

A trickle of new listings

The numbers lay bare how quiet the market has become. So far this year, the UK stock market has seen just seven new listings, which together raised a combined 557 million pounds, a modest haul for what was long a leading global financial centre.

The slowdown set in early and then stuck. Listings dried up at the very start of 2026 as companies grew wary of debuting into a climate of geopolitical volatility and mounting worries about stretched technology valuations.

What is scaring companies off

Several forces have combined to freeze the market. Heightened geopolitical tension, particularly the conflict in the Middle East, has made would be issuers cautious about timing a debut in such an uncertain and unpredictable environment.

The technology sector has added its own chill. Sharp resets in the valuations of companies linked to artificial intelligence and the wider tech industry have left many firms unsure whether public investors would offer them the price they want.

The pull of New York

For some companies, the answer has been to leave altogether. Concerns about London's struggling market peaked over the past year, driven by the dearth of new floats and by a series of high profile decisions to list elsewhere.

The fintech group Wise offered a striking example, choosing to move its primary listing to New York. Such moves sting because they suggest that even successful British companies see deeper and more welcoming pools of capital in the United States.

The trend shows up clearly in the data. Just 46 per cent of UK companies that went public in 2025 listed at home, a sharp drop from the 71 per cent that chose to do so back in 2019 before the mood soured.

More leaving than arriving

The problem is not only about new arrivals. The London Stock Exchange has recorded more delistings than new listings in every year since 2022, a steady erosion that shrinks the overall pool of publicly traded British companies.

That imbalance worries the wider ecosystem. Private equity and venture capital investors rely on public markets as an exit, a place to sell their stakes, and a weak listings market leaves their money locked up far longer than planned.

Waiting for a window

Rather than accept poor conditions, many companies are simply waiting. Potential candidates such as the bookseller Waterstones and the payments firm SumUp have been reported to be considering delaying any listing until 2027.

The pipeline itself is not empty, though. One analysis identified 87 UK companies with a high probability of reaching an IPO in the first half of 2026, including 27 businesses working in artificial intelligence, a queue waiting for the right moment.

A test for the City

The stakes reach far beyond individual deals. If London cannot offer a compelling home for its own fastest growing companies, it risks a slow drain of talent, capital and prestige toward rival financial centres across the Atlantic.

For now, patience is the watchword. With the lull expected to persist into 2027, the City's challenge is to reform and reassure quickly enough to convince the next generation of British startups that going public at home is still worth doing.
