It's no secret that Arm Holdings (NASDAQ: ARM) is a crucial piece of the artificial intelligence (AI) puzzle. But how often do you think of Arm as a top-shelf AI investment? It's easy to forget this impressive compounder amid the glitzy hypergrowth of Nvidia's and AMD's expensive AI accelerators.
Arm doesn't build the chips that train large language models. The company doesn't actually build chips at all. Instead, Arm designs fundamental instruction sets and CPU cores.
It licenses those designs to anyone with a fab contract and an ambition and collects a royalty on every unit shipped. It's basically a toll booth on a road that keeps getting wider. This Rare Signal Is Flashing Again.
In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue » Arm's toll road used to run almost entirely through smartphones.
Now it runs through the data center too. Nvidia's Vera CPU pairs Arm cores with its accelerators. Amazon's Graviton, Microsoft's Cobalt, and Alphabet's Google Axion are all Arm-based, built in-house by companies that spend like nation-states on server capacity.
Every AI cluster on the planet needs general-purpose compute to feed the high-speed AI accelerators, handle networking, and run the orchestration layer. A growing share of that work sits on Arm designs. The newer wrinkle is that Arm keeps climbing the value chain.
