Arm Made Its First Chip in 35 Years. Meta Is Buying First.
On March 24th, Arm Holdings unveiled its first-ever physical processor after 35 years of designing chips for others. The AGI CPU already has customers lined up - with Meta leading the pack.
For thirty-five years, Arm Holdings did one thing - designed processor blueprints and sold them to other companies. Apple, Nvidia, Amazon, Google - they all build their chips on Arm’s designs. The company was the “Switzerland of chips” - neutral, not stepping on anyone’s toes.
On March 24th, that ended.
The first physical chip
Arm unveiled the AGI CPU - its first production-ready processor ever. Not a prototype. Not a concept. A finished chip you can order now.
136 compute cores working simultaneously. Built by TSMC - the same factory that makes Apple’s chips - on their latest 3-nanometer process.
Arm claims more than double the performance per server rack compared to traditional AMD and Intel processors. Independent benchmarks don’t exist yet, but the promise is serious - one air-cooled rack holds over 8,000 cores. Liquid-cooled? 45,000.
Meta as co-developer and first customer
Meta didn’t just buy these chips - they co-developed them with Arm. Both companies committed to a multi-generation roadmap. The AGI CPU is designed to work alongside Meta’s own AI accelerators (MTIA) in their massive data centers.
Meta plans to spend $135 billion on AI infrastructure this year. The AGI CPU is one piece of that puzzle.
Other confirmed customers include OpenAI, Cerebras, Cloudflare, SAP, and SK Telecom. Over 50 companies - including AWS, Google, Nvidia, Microsoft, and Samsung - expressed official support.
The market reacted immediately
Arm stock jumped 16% in a single day. The company projects $15 billion in annual chip revenue within five years. In 2025, they made four billion.
Citi analysts called it “the most significant shift in the company’s history.” Hard to disagree - this is a fundamental rewrite of the business model of one of the most important players in semiconductors.
My take
The “Switzerland of chips” just entered the battlefield. This isn’t a minor strategy tweak - it’s a company that deliberately avoided competing with its own customers for over three decades, and is now producing exactly what they produce.
The question is how Apple, Amazon, and Nvidia will react. They’ve been buying designs from Arm and building custom chips. Now Arm offers a finished product that could be a cheaper alternative. That changes the dynamics of the entire market.
The AI infrastructure race just got a very serious new player.
