At 3:05 PM Berlin time on May 20th, ARM Holdings made a move few expected. Within 90 minutes, the stock climbed from $223 to $256 — a 15% gain in a single day. The reason was no standard earnings beat. It was the announcement of the ARM AGI CPU, the company's first proprietary silicon for datacenters.
The Transformation from Licensor to Infrastructure Player
ARM was known for decades as the IP licensor earning royalties on smartphone chips. Every ARM-architecture CPU sold brought a small royalty. The business model worked, but it was slow and predictable. With the AGI CPU, that changes fundamentally.
The company reported Q4 FY2026 revenue of $1.49 billion (+20% YoY). Licensing revenue rose 29% to $819 million, royalty revenue 11% to $671 million. For the full fiscal year 2026, ARM achieved record revenue of $4.92 billion (+23%).
But the spectacular number came from elsewhere: Hyperscalers like Google, Microsoft, and Meta committed over $2 billion in six weeks for ARM-based silicon in datacenters. This is no gradual expansion. This is a paradigm shift.
The Options Side: Call Volume Explodes
On May 20th, 23,540 ARM calls traded — 1.2x above normal volume. Implied volatility rose nearly 2 points. The signal was clear: Institutional players positioned bullish before the broader market understood the AGI CPU significance.
Strike clusters ranged between $240 and $280, with the highest open interest levels at $250 and $260. For June-expiry calls, premiums exploded an average of 140% within 24 hours. Put volume remained minimal — a rare sign of one-sided bullish flow without defensive hedging.
The call/put ratio reached 4.8:1, one of the highest readings for ARM since the 2023 IPO. Smart money was not betting on a short-term trade. Positioning concentrated on September and December expiries, indicating a medium-term thesis.
What Traders Watch Now
ARM's V9 architecture is the technical core of the story. V9 brings higher royalty rates than the old V8 generation — on average 2.5x per chip. V9 adoption accelerated in 2026: from smartphones and PCs to AI accelerators.
Datacenter royalties more than doubled in Q4 year-over-year. That's the result of AWS, Azure, and Google Cloud shifting to ARM-based instances. Intel's old dominance is crumbling.
Analysts from 24/7 Wall Street mark the zone between $210 and $215 as the preferred entry point on a pullback. At $256, ARM is stretched in the short-term chart, but the fundamental thesis remains intact: Anyone betting on AI infrastructure cannot ignore ARM.
Next catalysts: Hyperscaler earnings in June, further AGI CPU commitments, and the V9 adoption rate in the second half of the year. For options traders with risk tolerance, a bull call spread 260/280 with September expiry remains a structured bet on continuation — limited risk, asymmetric upside.
