Valuation gaps, not patriotism, decide where growth companies actually list

A Decision That Keeps Repeating Itself

By Chelsea Bloom. That a British semiconductor designer with deep UK roots chose Nasdaq over the London Stock Exchange for its public listing reflects a pattern considerably wider than any single company’s specific circumstances, part of a broader trend that has already pulled several high growth British firms toward US markets in recent years, driven less by sentiment than by a fairly cold, specific calculation about where investors will actually pay the most for their shares.

The underlying numbers explain the pull clearly enough. London’s entire 2025 IPO proceeds came to roughly one point nine billion pounds, while US exchanges raised more than forty billion dollars over the same period, a gap large enough that for a company weighing where to list, the decision becomes less about national loyalty and more about straightforward arithmetic regarding valuation multiples and available capital depth.

Why A Higher Valuation Changes The Entire Calculation

A company that lists at a meaningfully higher valuation can raise the same amount of capital while selling a smaller percentage of the business, a genuinely significant consideration for founders and early investors alike, meaning London’s valuation gap with New York functions as a direct, compounding disadvantage rather than a marginal one that reform alone can easily close.

A Personal Assessment Of London’s Available Responses

Having covered several rounds of proposed London Stock Exchange reform aimed at closing exactly this gap, from listing rule simplifications to the recently introduced stamp duty exemption for newly listed companies, I find the individual measures genuinely sensible but collectively still insufficient against a valuation differential this structurally entrenched.

A Gap That Requires More Than Incremental Reform

Until London can offer growth companies something closer to comparable valuations rather than simply a friendlier regulatory environment, the pattern of high profile listings heading to Nasdaq instead appears likely to continue, regardless of how many individual reforms the City introduces in the meantime.
