Should the federal government impose stricter regulation on AI data center expansion?

Sandisk shares fell 8.6% through 11:50 a.m. ET on Wednesday after Democrats won the 2026 midterm elections in a landslide. Investors feared the shift in government could affect AI data center spending and memory chip sales.

Why it matters

Investors worry a Democratic Congress is more likely to pass regulations on AI infrastructure than the prior Republican-led Congress. The sell-off spread to other AI and memory chip stocks as traders repriced policy risk.

Sandisk shares fell 8.6% through 11:50 a.m. ET on Wednesday, while the House stands at 228-139 with 68 seats unconfirmed. Final control of the House and the scope of any AI-related policy remain unresolved.

Market Dynamics

Policy expectations can move memory chip stocks even when underlying demand forecasts stay strong. Watch how the final House count and any proposed AI infrastructure rules affect the sector.
