AMD stock fell 10.88% on Friday, October 30, closing at $504.80, down $61.62 from the day before, according to [Yahoo Finance](https://finance.yahoo.com/quote/AMD). AMD did not announce anything that day. The drop was part of a chip sell-off that [Reuters](http://staradvertiser.com/2026/10/30/breaking-news/tech-stocks-tumble-as-amazon-intel-fuel-ai-spending-fears/) tied to weak results from Intel and Amazon and to worries about heavy AI spending.

AMD is worth about $925 billion, so a move of this size is large. It also comes four days before the company reports its own quarter.

## Why AMD stock fell

Reuters reports that results from Intel and Amazon, both released late Thursday, intensified concerns about AI-related spending. The Nasdaq Composite fell 2.86%, its sharpest one-day drop since June 5, and the S&P 500 fell 1.82%. Reuters says the broader semiconductor index dropped 7.2%. Nvidia fell 4.2% and AMD slid 10.9%, per the same report.

Intel was the center of it. Its shares fell 28.6%. [TechCrunch reports](https://techcrunch.com/2026/10/30/intels-stock-crashes-knocking-12b-from-governments-stake/) that Intel guided fourth-quarter revenue to $15 billion to $16 billion, against about $17 billion that analysts expected. CEO Lip-Bu Tan said customers "began signaling a PC slowdown based on the memory prices and availability," according to TechCrunch. We covered the details in [why Intel stock fell 28.6% on October 30](https://claudegpt.si/news/intel-stock-plunges-28-percent-october-30).

Neither Reuters nor TechCrunch says why AMD fell further than Nvidia. AMD has made no statement about the drop that we could find, and we found no AMD filing or announcement on October 30 that explains it.
