Google's TurboQuant Algorithm Sends Memory Chip Stocks Tumbling

Major memory chipmakers took a significant hit on Thursday after Google researchers introduced a groundbreaking compression algorithm that threatens to reduce artificial intelligence demand for memory chips. Samsung Electronics shares dropped 4.8%, while SK Hynix tumbled 5.9%, dragging the broader KOSPI index down by as much as 3% in one of its steepest single-day declines in recent months.

The selloff extended across global markets, reflecting overnight losses among U.S.-listed memory stocks. Micron Technology, SanDisk, Western Digital, and Seagate Technology each fell between 3% and 6%, signaling widespread investor concern about the long-term implications of the new technology on memory chip demand.

At the center of the market turbulence is TurboQuant, a newly unveiled algorithm developed by Google researchers. The tool is designed to significantly compress AI working memory requirements without compromising system performance. Beyond memory optimization, TurboQuant is also capable of enhancing vector search capabilities that underpin major search engines, broadening its potential applications across the tech industry.

For investors and analysts closely tracking the AI chip supply chain, the implications are substantial. A widely adopted memory-reduction technology could meaningfully slow the pace at which AI developers purchase high-bandwidth memory chips. This is particularly consequential for Samsung and SK Hynix, two of the world's largest and most advanced memory manufacturers, both of which have been key suppliers fueling the AI infrastructure boom.

AI-driven demand had been a primary catalyst behind a powerful rally in memory chip stocks over recent quarters, with supply shortages further inflating valuations. TurboQuant's emergence now introduces a credible downside risk to that growth narrative. Google has confirmed it will formally present TurboQuant at the ICLR 2026 conference in April, where the broader research and technology community is expected to scrutinize its scalability and real-world viability.
