SanDisk Plunges 19% as Democratic AI Regulation Threats Trigger Memory Sector Selloff

Key points

• SanDisk fell 18.83% to $842.04, while Micron dropped 14.71% and Western Digital fell 15.07% on November 5, 2026.
• The decline followed the November 3 midterm elections, where Democrats gained control of both chambers of Congress for the first time since 2023.
• Representative Yassamin Ansari posted on X calling for a pause on advanced AI development and regulation of the industry, raising fears of new restrictions on data center expansion.
• SanDisk reported Q1 FY2027 revenue of $11.03 billion, beating estimates for the sixth consecutive quarter, with data center revenue rising 61% sequentially to $4.80 billion.
• Analysts are divided on the impact, with some citing strong long-term supply agreements and global demand as buffers, while others warn of potential regulatory slowdowns in the U.S. buildout.

Background

SanDisk had already experienced volatility in late October and early November, dropping 9% on October 30 despite strong earnings and again on November 4 following election results. The company’s stock is down approximately 51% from its 52-week high of $2,354.39. Previous coverage noted concerns about a potential data center moratorium in Texas and conservative forecasts from joint venture partner Kioxia. The current sell-off represents a continuation of these fears, now amplified by the prospect of federal-level AI regulation following the Democratic sweep of Congress.

How outlets are covering it

24/7 Wall St. emphasizes the direct link between Representative Ansari’s call for an AI pause and the decline in memory stocks, noting that SanDisk is a pure-play NAND flash company heavily exposed to data center demand. Investing.com highlights the sector-wide nature of the selloff, pointing to bearish analyst actions from Fox Advisors and Wells Fargo, as well as an insider sale by SanDisk’s Chief Legal Officer, as contributing factors. Yahoo Finance and Seeking Alpha present a contrasting view, arguing that SanDisk is undervalued due to its strong financial metrics, including 84.6% non-GAAP gross margins and $93.9 billion in minimum revenue commitments from long-term contracts. Futurum Group CEO Daniel Newman, cited by 24/7 Wall St., argues that demand outside the U.S. remains sufficient to offset any slowdown in domestic buildouts, suggesting that forecasts may remain intact despite regulatory fears.

Why it matters

The performance of memory and storage stocks is a key indicator of investor sentiment toward AI infrastructure spending. A significant decline in these sectors could signal a broader reassessment of the AI boom, particularly if regulatory hurdles slow data center expansion. SanDisk’s strong financial results contrast with its stock price decline, highlighting the tension between current earnings power and future policy risks. The outcome of this debate will influence capital allocation in the semiconductor and data center sectors, potentially affecting global supply chains and technological development timelines.

What to watch

Investors will monitor whether the call for an AI pause translates into actual legislation or regulatory action in the new Congress. SanDisk’s next earnings report and any updates on its long-term supply agreements will be critical in assessing the durability of its demand. Analysts will also watch for signs of a shift in global demand, particularly outside the U.S., to determine if the current sell-off is a temporary correction or a more sustained adjustment. The Federal Reserve’s next policy meeting in December may also provide context for the broader market reaction to these regulatory fears.
