London Listings in a Post‑Brexit World: Drifts and Delistings
relevant butLondon used to sell itself as the natural home for British and European listings. In the post‑Brexit years, that slogan has been tested by a drip‑feed of companies drifting to New York, shelving IPOs altogether, or choosing alternative venues. The result in early 2026 is a UK equity market that is still deep and globally "gruellingly relevant" but fighting harder for new paper.
The warning signs appeared early. As far back as 2021, high‑tech UK firms such as Immunocore chose Nasdaq over London for sizeable IPOs, signalling an early preference for US valuations and liquidity in growth sectors. By mid‑2025, Bloomberg was describing London’s effort to revive its shrinking stock market as a "gruelling fight for listings", noting that payments group Wise had announced plans to move its primary listing to the US while Cobalt Holdings scrapped a planned $230 million IPO the night before trading was due to start. In the same period, fast‑fashion group Shein was reported to be shifting its IPO focus from London to Hong Kong, undercutting hopes for a marquee tech float.
The start of 2026 has not made things easier. Yahoo Finance UK reports that London IPOs “dried up” in the first quarter of 2026 as companies hesitated to debut in the face of geopolitical volatility and uncertainty over global rates. The London Stock Exchange’s own “New Issues” page shows a sparse pipeline compared with pre‑2020 norms, with many of the deals that do list being smaller, domestically orientated or private‑equity‑backed rather than large, global growth stories. Slaughter and May’s 2026 horizon-scanning report on UK equity markets expects to see more PE-backed IPOs as sponsors test conditions but acknowledges that London is competing head-to-head with New York, Amsterdam and Asian venues for those deals.
Several factors underpin this drift:
Valuation and sector mix: Tech and biotech firms in particular have tended to fetch higher multiples in US markets, where sector peers are listed and where specialist investors are more concentrated.
Liquidity and indices: Inclusion in large US indices can bring more immediate ETF and passive flows than a London listing, especially for growth names that do not fit neatly into the FTSE’s value‑tilted profile.
Regulation and perception: While the UK is reforming its listing rules and corporate governance codes to attract more issuers, the cumulative effect of Brexit‑related uncertainty and previous regulatory debates has made some boards more cautious about choosing London as their primary venue.
This does not mean London is “finished” as an equity hub. The exchange still hosts a substantial roster of global blue chips, and reforms to listing requirements, research rules and pension-fund allocations aim to make it more attractive for future IPOs. But it does mean that UK investors cannot assume a steady pipeline of domestic growth companies will automatically choose the LSE, and global investors cannot treat London indices as a complete reflection of British corporate dynamism.
In 2026, the story of London’s listings is one of competition and adaptation: a market that remains central to global capital flows, but which now has to work harder — and sometimes share issuer relationships with New York and other centres — to stay that way.
