Arm’s AI CPU push meets a brutal valuation

Arm tripled – Arm Holdings is riding a rapid shift in 2026 toward more CPU use in AI infrastructure—its shares have tripled since the start of the year—but the stock trades at 159 times analysts’ earnings estimates. Even with Arm projecting faster royalty growth and major p
By the end of the year, investors who chased Arm Holdings (NASDAQ: ARM) have one question dominating every scroll: can the stock really triple again after it already tripled this year?
The buzz starts with a clear change in how hyperscalers are building AI systems in 2026. For the last three years. many of their biggest spending priorities centered on graphics processing units (GPUs) and custom AI accelerator chips. Now that spending is shifting—adding large amounts of central processing units (CPUs). And for Arm, a company long known for mobile CPUs, the data center opportunity looks increasingly tangible.
Arm has already made headway in server chips over the past few years in a market historically dominated by Intel and. to a lesser extent. AMD. The logic is straightforward: energy-efficient Arm-based designs could become highly valuable inside power-hungry AI data centers—exactly the kind of environment where every watt matters.
That momentum is showing up in the stock. Arm’s shares have tripled in value since the start of the year, and investors are now weighing whether they missed a major turning point or whether another surge is even possible.
Arm’s own projections feed the optimism. At its investor day in March. Arm estimated the total addressable market for data center CPUs could reach $100 billion by 2031. up from $50 billion in 2026. During its most recent earnings call, AMD updated its server CPU market estimate to $120 billion by 2030.
What’s driving this CPU demand is agentic AI. CPUs are described as the orchestrators of servers of GPUs: deciding where data should move and handling machine-to-machine communication needs. In that framing, if GPUs are specialized labor, CPUs are the manager—and as agentic workloads grow, CPU demand increases. Intel CEO Lip-Bu Tan suggested the ratio of CPUs to GPUs could shift from 1:4 currently to 1:1 in the future as more work migrates to AI agents and they handle more complex tasks.
Arm says the market is moving toward it. In its fourth-quarter letter to shareholders, management said Arm’s market share of CPU compute among the top hyperscalers is about 50%. That claim is backed by statements from Nvidia and Amazon, both of which use Arm architecture for their CPUs.
Nvidia. for its part. said it has visibility to nearly $20 billion in total CPU revenue this year during its most recent earnings call. Amazon said its Graviton CPU is used extensively by 98% of its top 1. 000 customers. and it also recently signed a deal with Meta Platforms to deploy thousands of Graviton chips. The same push is described through Microsoft and Alphabet. which started deploying their own Arm-based CPUs in their data centers over the last few years and are ramping up quickly.
The demand is supposed to translate into faster growth for Arm’s business model. Management expects royalty revenue growth to accelerate from a 14% compound annual growth rate over the last five years to 20% over the next five years.
Then comes the most important pivot for investors: Arm wants to do more than license its designs.
For years. licensing its intellectual property has been highly profitable for Arm. but it only accounts for a tiny fraction of the spending on chips. Arm argues that selling its own designs directly can generate 10 times the gross profit per chip compared to the royalty model. Based on that, Arm developed the Arm AGI CPU.
Management expects to sell $15 billion worth of its own chips by 2031, which could generate $7.5 billion in gross profit. To provide scale, Arm’s gross profit totaled $4.8 billion for the full year 2025. Management says it is off to a strong start, with $2 billion in demand across 2027 and 2028. Still, Arm chose to maintain its outlook for $1 billion due to supply chain constraints.
There’s a belief baked into the projections: those constraints should ease over time. especially if Arm can show growing demand and secure longer-term commitments. The plan. according to management. is for a ramp-up in production and sales for its first-party chips. leading to significant profit growth around the end of the decade.
Arm also projected that its combined first-party chip and licensing businesses could generate about $25 billion in total revenue by 2031, resulting in $9 in earnings per share. That would be a dramatic jump from the $1.77 per share it generated last year.
But the dream of a repeat triple faces a harsh reality marker: price.
Arm’s stock currently trades for 159 times analysts’ earnings estimates. Even if Arm executes—growing its own chip business while royalty revenue accelerates as expected—the valuation is described as outrageously high. about 18 times management’s 2031 guidance. The takeaway is uncomfortable for anyone hoping for another surge: it’s not just hard to justify the stock at this level—it’s even harder to justify it while expecting it to triple once again.
That tension sits at the center of the story. Everything points to CPU momentum in AI data centers, and Arm has concrete milestones in market share and revenue forecasts. But the market is already pricing in a lot of future success. leaving less room for error—particularly when the next few years will depend on execution. supply chain resolution. and sustained adoption of Arm-based chips across major hyperscalers.
