ARM collects a royalty on every AI chip ever manufactured. Tomorrow's Q4 earnings will reveal whether building its own chip destroys the neutrality that makes the toll booth trusted. The licensing-versus-royalty split is the leading indicator.
Every AI chip pays ARM a royalty. NVIDIA's Grace. Amazon's Graviton. Apple's M-series. Google's Axion. Qualcomm's Snapdragon. MediaTek's Dimensity. Every custom hyperscaler design. The instruction set architecture is the toll booth, and there is no alternative route. ARM reported record royalties of seven hundred and thirty-seven million dollars in fiscal Q3, up twenty-seven percent year over year. Data center royalties doubled. The stock trades at two hundred and three dollars — a hundred and thirteen times forward earnings — up eighty-four percent this year.
Tomorrow ARM reports fiscal Q4. The consensus expects one point four seven billion dollars in revenue and fifty-eight cents in earnings per share. The options market is pricing a ten percent swing — roughly twenty-three billion dollars of market capitalization at stake in a single print. Nineteen analysts rate it a buy. The average price target is a hundred and eighty-four dollars, nine percent below where it trades today.
The earnings are not the story. What the earnings will reveal is.
The Neutrality Compact
ARM's moat has never been technical superiority. It has been trust. Every chipmaker licenses ARM's instruction set because ARM does not compete with them. TSMC thrives on the same principle — it manufactures everyone's chips because it designs no one's. Intel tried to be both chipmaker and foundry through Intel Foundry Services. It failed. CEO Lip-Bu Tan spun the foundry into an independent subsidiary specifically to address neutrality concerns and still has not attracted a single major external customer for its most advanced process node.
On March 24, ARM broke the compact. It launched the AGI CPU — its first in-house chip in thirty-five years, co-developed with Meta as lead partner. Eight committed customers including OpenAI, Cerebras, and Cloudflare. Revenue target: one billion dollars by 2028, fifteen billion by 2031. The stock jumped sixteen percent on the announcement.
ARM is betting it can be both the instruction set monopolist and a silicon competitor. The bet is that ISA lock-in is stronger than the neutrality premium — that customers literally cannot leave, regardless of competitive friction, because switching instruction set architectures would be an existential capability reset. Apple moving off ARM would require rewriting its entire software ecosystem. Amazon rebuilding Graviton on a different ISA would cost years.
The bet may be right. But the licensees have noticed.
The Friction
NVIDIA sold its entire ARM stake — one point one million shares, roughly a hundred and forty million dollars — in February 2026. It retains a twenty-year license but wants zero equity exposure to a company now competing with Grace via AGI CPU. Qualcomm filed a counter-lawsuit alleging breach of contract and improper interference with customer relationships, claiming ARM is hindering innovation to benefit its own products. Morgan Stanley downgraded ARM on April 7 from Overweight to Equal-Weight, explicitly warning of channel conflict that could push Apple and Qualcomm toward RISC-V.
RISC-V now holds twenty-five percent global market share, growing at a compound annual rate above thirty percent. The Quintauris joint venture — Qualcomm, Bosch, Infineon, NXP, STMicro — is standardizing RISC-V for automotive. China is accelerating: Alibaba, Nuclei System Technology, and Huawei are all premier RISC-V International members. RISC-V is not yet ready for high-performance data center compute, but every licensee friction event accelerates investment in the alternative.
The competitive dynamic is asymmetric. ARM's ISA lock-in is stronger than Intel's was — Intel's customers had TSMC as a credible alternative and migrated to it. ARM's customers have no credible ISA alternative today. But the absence of an alternative today is not the same as the absence of one tomorrow. Every quarter ARM competes with its licensees is a quarter those licensees invest more heavily in escaping the dependency.
The Margin Math
ARM's IP licensing model produces gross margins above ninety-five percent. Merchant silicon — designing, manufacturing, and selling physical chips — produces margins of forty to fifty percent. The AGI CPU is a deliberate decision to dilute the highest-margin business in semiconductors.
The bulls argue the dilution is temporary and the total addressable market expansion compensates. Evercore ISI raised its price target to two hundred and twenty-seven dollars, projecting fifteen billion in AGI CPU revenue by 2031. Wells Fargo raised to two hundred and twenty dollars, citing agentic AI creating a CPU bottleneck that plays to ARM's architecture. The bear case is simpler: R&D headcount is surging at a record pace, operating expenses face eight-plus quarters of pressure, and even if AGI CPU revenue reaches one billion by 2028, the margin compression is real and immediate.
SoftBank contributes two hundred million dollars per quarter to ARM's license revenue — a related-party arrangement that inflates the licensing line. Strip SoftBank out and the organic licensing growth rate is the number that matters.
What to Watch
Tomorrow's earnings will answer one question: is the toll booth still trusted?
The key metric is not total revenue. It is the split between licensing and royalties. Royalties are a volume proxy — they track chips already shipped, and shipped chips do not care about competitive concerns. Licensing is a forward commitment proxy — new deals signed, new architectures adopted, new customers betting their product roadmaps on ARM. In Q3, royalties were seven hundred and thirty-seven million dollars and licensing was five hundred and five million. Management guided Q4 royalties up low teens and licensing up high teens year over year.
If licensing growth decelerates while royalties accelerate, the neutrality tax is real. Customers are shipping ARM chips they already committed to while slowing new commitments as they evaluate competitive risk. A widening gap between the two growth rates is the leading indicator that the toll booth's trust premium is eroding.
Three predictions, each testable against tomorrow's print. First, royalty revenue will exceed eight hundred million dollars — AI chip volumes are growing regardless of competitive concerns. Second, licensing revenue will meet or narrowly beat guidance — ISA lock-in is too strong for near-term defection, even with friction. Third, management will address the NVIDIA stake sale and Qualcomm litigation on the earnings call, because the market is asking and silence would be worse than any answer.
ARM is the most elegant business model in semiconductors — collect a percentage of every chip, regardless of who designs it, who manufactures it, or who wins the model race. The AGI CPU is a bet that owning the chip is worth more than owning the neutrality. Tomorrow we find out whether the market agrees.
