After Arm shunned a London listing in favor of New York, some VCs in the UK blame Brexit and institutional investors, who lack a good understanding of tech
- British chip designer Arm recently decided to list in New York, leading to worries that London will miss out on more blockbuster tech IPOs.
Context & Ripple Effects
Arm's path away from London was long and public: SoftBank first paused talks about a London listing in mid-2022 amid UK political turmoil, then PM Rishi Sunak personally met CEO Rene Haas and Masayoshi Son in January to revive a dual listing — before Arm settled on a sole New York listing. Officials and SoftBank staff had already pinned the loss on onerous FCA rules, complexity and cost, so today's VC finger-pointing at Brexit and institutional investors widens the circle of blamed parties.
The stakes go beyond one chip designer: related coverage already shows London waning as a fintech hub with startups calling for reforms after SVB UK's bust. If Cambridge's most valuable tech company lists in New York, London risks losing the marquee IPOs it needs to keep its growth-market credibility.
First-order effects
- London loses its highest-profile tech IPO candidate outright, a direct rebuff after direct intervention by the Prime Minister; SoftBank gains a simpler, faster route to cashing out its Arm stake.
- UK venture capitalists now openly tie the miss to Brexit-era institutional investors who they say lack understanding of tech — turning a corporate listing decision into a referendum on UK capital markets.
Second-order effects
- Other UK-grown startups approaching IPO will face investor pressure to consider sole US listings too, since Arm has shown even a politically championed dual-listing effort can fail; expect renewed calls for FCA listing-rule reform from founders and VCs.
- New York's exchanges gain a fresh proof point in competing for European tech floats, sharpening the pitch that US markets price deep-tech better than London's institutions do.
Third-order effects
- If the pattern holds — political turmoil, regulatory friction, and thin local tech appetite each cited across this coverage — UK policy may shift toward structural market reforms to retain listings, while Europe's flagship tech companies increasingly treat Nasdaq as the default exit.
- The episode feeds a longer divergence in which the UK's startup ecosystem and its public-market capital base grow apart: venture-backed companies scale on US capital, leaving London's exchanges concentrated outside tech unless investor composition or rules change.
The trend: Europe's marquee tech companies are drifting toward US listings as UK capital markets struggle with post-Brexit investor depth, regulation, and political instability.
