AI Spending Fears Spark Micron and Nvidia Stock Plunge
Key Summary
AI spending fears have led to a sell-off in Micron and Nvidia shares, with the chipmakers' stock falling 4% and 1.3-1.8% respectively. The pressure builds on the sector after a Financial Times report on OpenAI's finances revealed a revenue gap between expected and actual figures, fueling concerns about the monetization of AI infrastructure.

The AI Trade Had Another Rough Day
The AI trade had another rough day, with Micron shares falling 4% to 4.5% and Nvidia slipping between 1.3% and 1.8%. Those moves capped a brutal stretch for chipmakers, with 20 major AI and semiconductor stocks losing over $1 trillion in combined market value.What Set Off the Latest Sell-Off
The pressure built sharply between October 13 and 15, triggered by a Financial Times report on OpenAI's finances. According to the report, OpenAI's annualized revenue run rate stood at approximately $50 billion as of September 30, which is lower than the market's expectations of $68 to $70 billion.Strong Results, Nervous Investors
Micron has achieved record gross margins and secured significant contracts to supply high-bandwidth memory, or HBM, in 2026. However, the spending forecasts themselves remain staggering, with US hyperscalers projected to spend around $800 billion on AI-related capital expenditures in 2026.The Core Tension
The core tension is between near-term demand and long-term return. The OpenAI revenue gap suggests the monetization side may be running behind the build-out.What This Means for Chip Investors
For Micron specifically, the setup is two-sided. Record margins and locked-in HBM contracts for 2026 offer visibility. Yet memory has historically been a cyclical business, which is why talk of future oversupply and CXMT's DRAM progress hits the stock harder than its peers.CoreWeave's Soaring Bond Yields
CoreWeave's soaring bond yields are a signal of how credit markets view AI companies that have borrowed heavily against future demand. If financing conditions keep tightening, that stress could spread to their suppliers through slower orders or renegotiated commitments.What to Watch from Here
US inflation data will shape rate expectations and, by extension, the cost of funding data centers. Hyperscaler capital spending guidance will show whether the projected $800 billion for 2026 holds up. And any further updates on AI revenue, from OpenAI or others, will test whether this week's fear was an overreaction or an early warning.#AI#US#Crypto#Chipmakers
