10 most popular stocks in August 2025 on Robinhood UK
A few familiar faces were joined by a couple of sector newcomers, with rare earth miners appearing alongside AI and crypto names as the most popular stocks in October 2025 on Robinhood UK.
The changing face of crypto mining leads October’s themes
The Bitcoin price may have taken a breather in October but that didn’t dent appetite for a couple of BTC-adjacent stocks. MARA (previously Marathon Digital) made its first major BTC sale in over a year, shifting half the Bitcoin it mined in September. It marks a move from ‘hold at all costs’ to more of a crypto treasury strategy, which clearly drew investors’ attention. And, once known purely as a Bitcoin miner, IREN has pushed into cloud computing - AI data centre contracts in particular - in an effort to boost revenues. A $875m raise in October to fund further expansion might be behind appetite for the stock over the month. And CleanSpark got a boost after announcing plans to build AI data centres as well as mining Bitcoin.

Despite a premium valuation, NVIDIA continued to attract investors in October as it announced $120bn worth of AI partnership deals and won US approval to ship 500,000 chips per year to the UAE. Staying in AI, AMD had a positive month after it confirmed a deal to supply 6 gigawatts of graphics processing units (GPU) to OpenAI, marking one of its largest AI partnerships to date. Dutch AI infrastructure firm, Nebius, launched its AI Cloud 3.0 Aether platform during the month, as well as expanding a $17bn GPU-capacity partnership with Microsoft.
It was a mixed month for Tesla as profits just fell by more than a quarter, even with record vehicle deliveries as US buyers rushed to buy electric vehicles (EVs) before tax credits ran out. Operating expenses were up 50% to $3.4bn with a lot of that going on NVIDIA chips to fuel autonomous driving. The US government reducing fines for non-compliance on car emissions standards to zero halted the benefit of selling emissions credits to rivals too. And tariffs are making importing essential components like rare earth minerals for electric vehicles much more expensive.

On that note, rare-earth stocks USAR and CRML made the list as tariff-led conversations around resource security hit the spotlight. Beijing reporting export controls this month heightened trade tensions with the US and put in jeopardy the supply of minerals used in the likes of EVs and smartphones. A delay or détente could well take the air out of the sector rally and, with share prices well off their recent peaks, the market might already be eyeing a chance of that happening.
