AI Agent Boom Shifts Workloads to CPUs, Driving AMD to $1 Trillion

Key points

• AMD stock jumped 32% in the past month, reaching a record high of $649.42 and entering the trillion-dollar market cap club.
• Meta's Muse AI agent, launched in early September, topped the Apple App Store in less than two weeks and has surpassed 5 million downloads.
• OpenAI released its AI agent Dots last week, which runs on AMD EPYC CPUs, following Meta's lead in adopting CPU-heavy agent infrastructure.
• AMD's data center revenue more than doubled to $6.7 billion in the quarter ended in June, representing nearly 60% of total company sales.
• Analysts estimate Muse's serving costs at an average of $37 per user per month, with Morgan Stanley projecting it could account for 20% of AMD's 2026 chip sales.
• AMD's third-quarter revenue forecast is approximately $13 billion, up from $11.5 billion in the second quarter, though supply chain constraints remain a concern.

Background

In late September, AMD shares jumped 9% after Meta's Muse agent topped the App Store, signaling growing AI-driven demand for AMD CPUs. Meta's stock also surged to record highs, nearing a $2 trillion valuation, as Muse accumulated over 2.5 million downloads in 13 days. Citi subsequently raised its AMD price target, projecting 25% upside, while noting concerns about Meta's cash flow. Earlier coverage highlighted that Muse's rapid adoption triggered a selloff in traditional brokerage stocks, as investors feared AI agents would disrupt legacy financial intermediaries.

How outlets are covering it

CNBC emphasizes the structural shift from GPUs to CPUs as AI agents execute long-running tasks, citing AMD's strong market share and x86 architecture compatibility. TheStreet Pro focuses on technical indicators, noting AMD's strong buy signals and momentum, while suggesting the stock is poised for further gains. Trefis questions the valuation, noting AMD trades at 160.2 times earnings, significantly higher than the S&P 500's 21.5 times, and highlights supply chain tightness as a risk. Citi, as reported in the archive, sees 25% upside but notes Meta's free cash flow dropped to $784 million in Q2 2026, raising questions about sustainability. Meta and OpenAI both maintain CPU-agnostic approaches, using multiple providers, but AMD currently leads in hyperscaler deployments.

Why it matters

The rise of AI agents is reshaping the semiconductor market, moving focus from GPU-centric AI training to CPU-centric agent execution. This shift benefits AMD and Intel, which dominate the CPU market, while challenging Nvidia's dominance. The CPU market is forecast to reach $220 billion by 2030, up from $60 billion in 2025. AMD's ability to supply both CPUs and GPUs positions it well, but supply chain constraints and high valuations pose risks. Investors are watching AMD's third-quarter results to gauge whether it can meet its $13 billion revenue forecast and sustain growth.

What to watch

AMD's third-quarter earnings report is expected later this month, with revenue forecast at approximately $13 billion. Investors will watch whether AMD can meet the lower end of its forecast, which would raise concerns about supply chain tightness. Meta's Muse adoption and monetization will also be key, as the company has not yet reported revenue from the agent. Nvidia's Vera CPU, designed for agents, will compete in the market, but analysts believe AMD currently has the best product. The CPU market is expected to grow rapidly, with AMD aiming for more than half of the market share.
