Arm, the most exciting company to come out of the UK since… Who knows? It’s been a while since the words "UK" and "exciting" were even in the same sentence. Arm is involved in the semiconductor ecosystem as a designer for things like processors. It then sells and licenses its fancy designs to tech companies with a whopping 99% of smartphones using Arm-based processors.
Its 2023 initial public offering (IPO) was a success and reignited investor interest – even though it decided to list in the US instead of the UK (we’re not bitter about it, honestly). With a surge in AI and cloud computing, demand for Arm’s technology is growing. Buying Arm shares is a way to gain exposure to the backbone of modern computing, but competition is heating up and it’s reliant on major licensees like Apple and Nvidia.
The whole process can take as little as 15 minutes. You'll need a smartphone or computer, an internet connection, your passport or driving licence and a means of payment.

"It's impossible to predict with any degree of certainty. Still, if we look at past IPOs, there's likely to be plenty of immediate volatility as the market attempts to price Arm shares.
Once the dust has settled and the hype dies down, Arm will be treated just like any other stock. Its finances will become much more public, and investors can dig into the company to decide if the shares are worthy of the price tag.
The Arm IPO was a great springboard, but it's now up to the company to perform and showcase that it deserves to be held in such high esteem among the other major semiconductor stocks. "
Contrary to popular belief, Arm doesn't actually make chips (semiconductors). Arm creates designs for chips and then sells or licenses the intellectual property (IP) to big tech firms. So it's not a manufacturer, more of a research company.
However, this is partly what makes Arm so valuable. It doesn't matter whether a phone is Android or iOS, Samsung or Apple, every piece of hardware can potentially use Arm's chip designs.
This is why you'll see crazy stats showing that Arm chips can be found in over 90% of smartphones worldwide. The ability to customise Arm chips for different firms and devices makes it a very unique semiconductor business.
