Top 2 Growth Stocks on the London Stock Exchange: Wise & Boku - Are They Worth Buying? (2026)

When it comes to growth stocks, the UK market often takes a backseat to its flashier American counterpart. After all, who can ignore the meteoric rise of tech giants like Nvidia and Palantir, boasting gains of 627% and 1,665% over just three years? But here’s the thing: the London Stock Exchange is home to some seriously underrated growth stories that deserve more than a passing glance. Personally, I think the UK’s lesser-known companies offer a unique blend of innovation and value that’s hard to find elsewhere. Let’s dive into two such gems that I believe are worth your attention.

Wise: The Unsung Hero of Fintech

One thing that immediately stands out is Wise (LSE:WISE), a £10.8bn market-cap giant in the international money transfer space. What many people don’t realize is that Wise is quietly reshaping how we think about cross-border transactions. While it’s shifting its primary listing to the US—a move that’s both strategic and symbolic—it’s keeping a secondary listing in London, where its shares currently trade at 1,050p. At first glance, its forward P/E ratio of 26.5 might seem steep, but if you take a step back and think about it, the valuation starts to make sense.

What makes this particularly fascinating is Wise’s growth trajectory. Last year alone, it grew underlying income by 19% to £1,619m, increased cross-border volume by 25% to £181.7bn, and expanded its customer base by 21% to 18.9 million. These aren’t just numbers—they’re a testament to Wise’s ability to disrupt a traditionally slow and expensive industry. From my perspective, the real game-changer is its focus on speed and affordability. With 75% of transfers now instant, Wise is setting a new standard for what’s possible in fintech.

But here’s where it gets interesting: Wise is lowering its take rate as it scales. While some investors might see this as a sacrifice of short-term profits, I see it as a brilliant long-term play. By prioritizing accessibility, Wise is positioning itself as the go-to platform for both individuals and businesses. This raises a deeper question: Can Wise maintain its growth momentum in a potentially volatile global economy? The ongoing tensions in the Middle East and inflationary pressures are certainly risks, but I’m betting on Wise’s resilience. As a long-term investor, I’m happy to hold it as a top-10 position in my portfolio, especially with its year-to-date gain of 21.5%.

Boku: The Hidden Gem in Payments

Now, let’s talk about Boku (LSE:BOKU), a much smaller player with a £525m market-cap but an outsized impact on the global payments landscape. What this really suggests is that size isn’t everything when it comes to innovation. Boku’s niche? It connects the world’s largest merchants with local payment methods (LPMs) in over 60 countries. Imagine someone in Thailand subscribing to Netflix using their digital wallet—Boku is the invisible force making that transaction seamless.

A detail that I find especially interesting is Boku’s growth story. Revenue jumped 30% to £129m last year, and analysts predict it could surpass £210m by 2028. With LPMs expected to dominate 60% of the $11 trillion global e-commerce market, Boku is perfectly positioned to ride this wave. What’s even more impressive is that it’s doing this while remaining profitable—a rarity in the fintech space.

In my opinion, Boku’s valuation is a steal. Trading at just 18 times next year’s forecast earnings, it’s a bargain for a company growing at 20% annually. But here’s the catch: competition in the payments space is fierce, and a global downturn could slow its momentum. Still, I reckon this under-the-radar stock is worth buying for the next five years. It’s not just about the numbers; it’s about the broader trend of localization in e-commerce, which Boku is at the forefront of.

The Bigger Picture: Why These Stocks Matter

If you take a step back and think about it, Wise and Boku aren’t just growth stocks—they’re symbols of a shifting financial landscape. Fintech is no longer a niche sector; it’s the backbone of global commerce. What many people don’t realize is that the UK is quietly becoming a hub for innovative financial solutions, even if it doesn’t grab the same headlines as Silicon Valley.

From my perspective, the real opportunity here is in recognizing these companies as more than just investments. They’re pioneers in a world where borders are blurring, and transactions are becoming instantaneous. Personally, I think the next decade will be defined by companies like Wise and Boku, which are not just growing but reshaping entire industries.

Final Thoughts

So, should you buy these stocks? In my opinion, it depends on your risk appetite and investment
