CPU chip stocks and Meta are surging as AI agents shift demand from GPUs to CPUs, which is good news for investors in AMD, Intel, ARM and advertising platforms.

• AMD jumped 10% to a $1 trillion market value and Meta rose 11% after Meta's new AI agent app, Muse, hit the top of the app store charts.
• AI agents run well on CPUs, not just GPUs, so money is rushing into CPU makers like AMD, Intel and ARM, with Intel raising prices because it can only fill half of customer demand.
• Nvidia is being left behind for now, but it is entering the CPU business with a $20 billion sales forecast and has far more supply locked up than AMD.
• AI apps are spending heavily on ads to win users, which helps Apple, Google, Netflix and Meta as advertising platforms.
• AMD looks overbought in the short term, while Nvidia, Broadcom and Cerebras look like better-valued opportunities.

Outlook: The agentic AI boom is still early, with stocks expected to hit all-time highs by Black Friday, though AMD may cool off after its rapid run.
