The CPU market is experiencing a massive resurgence, fueled by the rapid development of Agentic AI. Last week, a bullish report from Bernstein ignited the sector, sending Arm Holdings(ARM.US) up over 46% for the week and pushing its market cap past $320 billion. Bernstein initiated coverage with a $300 target (bull case $390), projecting ARM will quadruple its server CPU market share over the next four years.

The Catalyst: Agentic AI Drives a CPU Supply Crunch

While GPUs have dominated traditional AI training, the new era of "Agentic AI" requires complex workflows such as task planning, tool invocation, and multi-model scheduling—tasks that rely heavily on CPUs.

Industry leaders are bracing for an unprecedented demand shock:

• Intel Corporation(INTC.US)& Arm Holdings(ARM.US): Intel notes the CPU-to-GPU ratio is shifting from 1:8 toward 1:1 (or even 4:1). ARM estimates AI Agent data centers will require 120 million CPU cores per gigawatt—a 4x increase from traditional AI.
• Advanced Micro Devices, Inc.(AMD.US): CEO Lisa Su raised the 2030 server CPU Total Addressable Market (TAM) to over $120 billion.
• Price Hikes: Global server CPU prices have already jumped 10%-20%, with AMD and Intel planning further hikes in H2 as supply remains tight.

A Shifting Landscape: Nvidia and ARM Enter the Fray

The CPU space is no longer just an Intel/AMD (x86) duopoly. NVIDIA Corporation(NVDA.US) has officially entered the market with its independent Arm-based "Vera" CPU, targeting $20 billion in standalone revenue this year with early deliveries to OpenAI and Oracle. Concurrently, ARM has pivoted from a pure IP licensor to a chipmaker, launching its first "AGI CPU." 

Top US-Listed CPU Concept Stocks to Monitor:

• Arm Holdings(ARM.US): Officially transitioning from an IP licensor to a chipmaker. Its first self-developed AGI CPU has already been delivered to Meta and OpenAI, with customer demand doubling from $1B to $2B in just six weeks.
• Advanced Micro Devices, Inc.(AMD.US): Benefiting from a dual-engine strategy (EPYC CPUs + Instinct GPUs). Its "Venice" EPYC processor is standard in Nvidia’s Rubin NVL72 racks. Q1 server CPU revenue share hit a record high of 46.2%.
• Intel Corporation(INTC.US): Its Xeon 6 processor was chosen for Nvidia's DGX Rubin host CPUs. Secured a 3-5 year supply deal with Google, with Q1 data center AI revenue up 22% YoY.
• NVIDIA Corporation(NVDA.US): Advancing on both CPU and GPU fronts. The new Vera CPU targets $20 billion in independent revenue this year, while next-gen Rubin GPUs enter mass production in Q3.
• QUALCOMM Incorporated(QCOM.US): Officially announced a return to the server CPU market, developing custom data center CPUs designed to plug into Nvidia's racks.
• Taiwan Semiconductor Manufacturing Co., Ltd. Sponsored ADR(TSM.US): As the world's largest semiconductor foundry, it remains the most direct beneficiary of the explosive, broad-based surge in global CPU manufacturing demand.
