There are some phenomenal growth stocks in the UK right now. And several have started going on an absolute rampage in 2026. Chief among them is Raspberry Pi (LSE:RPI), which has erupted 174.1% in the last six months alone!
Just to put that into money terms, a £500 investment near the start of 2026 is now worth close to £1,370.50. But even at today’s now-elevated share price, anyone with £500 to spare can still snap up 60 shares right now. The question now is, can Raspberry Pi surge again?
From hobbyist gadget to AI infrastructure
As a quick reminder, Raspberry Pi designs and manufactures low-cost, high-performance, single-board computers and microcontroller chips, selling into three markets:
- Industrial & Embedded.
- Enthusiasts & Educators.
- Semiconductors (growing rapidly).
So why has the share price gone parabolic? The simple answer is that Raspberry Pi has found itself in an unexpected sweet spot within the AI boom.
As hyperscalers and enterprises race to build out AI infrastructure, demand has surged for affordable, programmable edge computing hardware. Raspberry Pi’s boards, which already have an established reputation among engineers worldwide, have become a go-to solution for developers prototyping and deploying AI applications on a budget.
The full-year 2025 results published in March confirmed the scale of the opportunity. Revenue rose 25% to $323.2m, pre-tax profits jumped 63% to $26.5m, and earnings per share surged 73%.
Needless to say, those are some pretty impressive figures. And it seems that management agrees, given it’s now raised its full-year guidance for 2026.
The case for buying today
Raspberry Pi’s evolving from a single-product hardware business into a two-franchise model. Its RP2040 and RP2350 microcontroller chips from its Semiconductor division shipped 8.4 million units in 2025. That’s a 47% increase year on year. And for the first time that exceeded board and module shipments.
The US market’s also growing fast, jumping 56% in 2025, partly because Raspberry Pi’s exclusively UK-manufactured products carry lower tariffs than China-manufactured rivals under the new global trade regime. And that structural advantage is likely why the average consensus among institutional analysts is to Buy shares today.
However, despite this optimism, there are some potential red flags to consider.
While Buy recommendations might be floating about, the share price forecasts are far less bullish, with the average price target currently sitting at 479.2p per share. That’s almost half where the stock’s trading today, signalling a pretty lofty valuation.
Seeing a high-quality growth stock trade at a premium isn’t unusual. However, it does set the stage for potentially extreme volatility if something goes wrong. And sadly, that’s a real possibility.
Memory prices have surged on the back of AI-driven demand, applying enormous pressure on margins across the sector. So far, Raspberry Pi’s been cushioned from this impact by drawing down on its existing inventory stockpiles. But once those are depleted, the group’s unit economics could come under massive pressure as we move towards 2027.
So what’s the verdict?
Raspberry Pi’s one of the most exciting growth stocks to emerge from the UK in years. But at today’s valuation, this isn’t a stock for the faint-hearted. And personally, the risk-to-reward ratio doesn’t look very tempting. But luckily there are lots of other growth opportunities for me to explore…
