SanDisk Slides 7%, Micron and Western Digital Fall 5% as Lawmaker’s Call for AI Pause Extends Memory Rout

SanDisk slid 7% and both Micron and Western Digital fell 5%, while Seagate Technology dropped more than 4%, according to the coverage. The moves unfolded as a U.S. lawmaker publicly urged a pause on artificial‑intelligence development, a stance the reports say has extended an already‑emerging rout in memory‑chip equities. Yahoo Finance framed the slide as a reaction to the lawmaker’s AI‑pause appeal, explicitly tying the 7% SanDisk decline and the 5% falls at Micron and Western Digital to the political signal. Moomoo reported the broader pre‑market weakness, noting Seagate’s over‑4% drop alongside the sector‑wide sell‑off.

Seeking Alpha, in contrast, focused on valuation, describing SanDisk’s price‑to‑earnings‑growth (PEG) ratio of 0.12× as “just too cheap.” The three outlets together highlight price movement, political influence, and fundamental valuation metrics. The memory‑chip market has been closely linked to demand for AI hardware, where higher‑capacity storage drives revenue for manufacturers. A legislative call for an AI development pause introduces uncertainty about future spending on AI‑related infrastructure, which analysts see as a potential headwind for memory demand. A PEG ratio of 0.12×, as noted by Seeking Alpha, signals an unusually low valuation relative to growth expectations, a factor that may attract value‑oriented investors despite the sector’s volatility.

Future coverage should watch whether the lawmaker’s AI‑pause proposal advances in Congress, as any regulatory shift could further pressure memory‑chip pricing. Market participants will also monitor intra‑day price action for SanDisk, Micron, Western Digital and Seagate to gauge the depth of the sell‑off. Analyst commentary on valuation, such as additional PEG assessments, may influence buying interest, while broader technology‑sector trends will provide context for any reversal or continuation of the current rout.
