Shares of memory chipmaker Micron Technology (MU) tumbled 17% as a chip sell-off deepened on Thursday.

Peer SK Hynix (SKHY), along with memory and storage names Sandisk (SNDK), Seagate (STX), and Western Digital (WDC), were all down double-digit percentages.

Shares of Micron and other chip stocks declined significantly over the past month amid growing worries of an overextension of the AI trade. The sell-off gained steam on Thursday after Democrats won control of both the House and Senate, raising concerns about a slowdown in data center buildouts.

AI chipmakers Nvidia (NVDA) and AMD (AMD) sank 9% and 17%, respectively, on Thursday. Broadcom (AVGO) also sank 10%.
