AI Trade Cools and Oil Prices Slip: Wall Street’s Volatile Week

Wall Street’s week was defined by a rapid reversal in the AI-related trade. After Micron Technology posted earnings that more than quadrupled year-over-year revenue, its shares surged 16% on Thursday, briefly lifting peers such as SanDisk, Western Digital, Applied Materials and Lam Research. The rally was short-lived; Micron fell 6.7% on Friday and closed the week down 0.15%, while a broader basket of AI chip makers posted double-digit losses—Nvidia (-8.6%), Broadcom (-12.3%), Intel (-4.2%) and Arm (-23.9%). The sell-off was amplified by reports that OpenAI may postpone its initial public offering until next year, raising doubts about the durability of funding for AI infrastructure. Apple’s announcement of price increases for MacBook and iPad models—citing soaring memory and storage costs—sent its stock down 6.1%, marking the first formal pass-through of component price pressure to consumers. The Nasdaq Composite slipped 4.6% for the week, the S&P 500 fell 1.95%, while the Dow Jones Industrial Average edged up 0.6% as lower oil prices buoyed economically sensitive sectors.

The AI boom has driven hyperscalers—Amazon, Alphabet, Microsoft and Meta—to invest heavily in data-center capacity. This surge has strained the supply of memory and storage components, creating a “hardware bottleneck” that pushes input costs higher. Companies that manufacture the underlying chips and related equipment have become the primary beneficiaries, while firms that purchase the compute power face margin compression.

Micron’s earnings release highlighted “blockbuster” revenue growth and announced 16 long-term supply agreements spanning data-center operators, automakers and other customers. Jim Cramer’s commentary emphasized that AI-related firms with product shortages retain pricing power, while recommending a focus on “picks and shovels” providers. Apple’s pricing decision was framed as a response to “soaring memory and storage costs.” FedEx reported earnings that beat expectations, noting continued momentum in higher-margin logistics segments, including AI-related data-center freight. FedEx Freight management described demand as “beginning to stabilize after a multiyear downturn.”

CNBC

Analysts expressed concern that the potential delay of OpenAI’s IPO could constrain capital for AI infrastructure projects, heightening the risk of a prolonged funding shortfall. Rising component costs have prompted investors to rotate away from AI-buyer stocks toward suppliers, reflecting skepticism about the sustainability of current spending levels.

Despite President Donald Trump’s accusation that Iran violated a cease-fire by attacking commercial vessels, oil markets showed minimal reaction, with WTI and Brent prices remaining near $70 / bbl. The sources do not provide a timeline for when memory-chip supply constraints might ease, leaving uncertainty about the duration of the hardware bottleneck.

Market participants will watch for an updated timeline on OpenAI’s IPO, continued quarterly reports from memory-chip manufacturers, and oil price movements as geopolitical tensions evolve. FedEx Freight’s demand outlook will be monitored for signs of sustained stabilization, while investors assess whether the shift toward AI-supplier equities persists.
