The rally in CPU stocks tied to AI agents looks overdone, which is a warning for anyone chasing Intel and AMD here, though the big AI chip makers still look fine.

• Intel and AMD have tripled this year on excitement about AI agents needing armies of CPUs.
• The math does not support it: one AMD server chip could run 900 agents, so even a billion agents by 2030 would need only about 1.2 million CPUs.
• That works out to a few billion dollars of sales spread over years, which Nvidia earns from data centers in under a week.
• Agents barely need power at all — a $400 mini PC or even a cheap phone can run one for pennies a day.
• The real money stays at the frontier, where OpenAI, Anthropic, and Elon Musk keep pouring cash into top-end Nvidia and AMD chips.

Outlook: Near-term moves hinge on whether an Iran deal lands, but the CPU trade looks stretched and memory may be the tighter bottleneck.
