SanDisk Tops 2026 Assets, Shares Up 509% on AI Demand

SanDisk’s stock gained 509% between Jan. 1 and May 20 after the company reported revenue of $5.95 billion, a 251% year-over-year increase, and disclosed a $42 billion order backlog from cloud customers linked to demand for AI memory.

In an April 30 earnings release, SanDisk said strong sales of memory chips used in data centers training large artificial intelligence models drove results. The stock reached an intraday record of $1,562 on May 8 and traded near $1,383 on May 20. A $1,000 investment in SanDisk at the start of the year would have been worth about $6,090 as of May 20. The share price had pulled back more than 11% from its peak by that date, after a period of sharp intraday and weekly swings.

Among a group of 15 assets tracked through May 20, SanDisk led the list. The runner-up was the DeXe crypto token, which gained 363% in the same period. Hardware suppliers within the AI supply chain also posted large gains: Intel rose about 209% and Seagate about 183%.

Major market benchmarks recorded smaller gains. The Nasdaq 100 added roughly 16%, the S&P 500 rose about 9.1%, and the Dow Jones Industrial Average gained 3.9% from the start of the year through May 20.

Some assets that opened 2026 with high expectations lost value. Bitcoin fell from about $87,600 to roughly $76,800, a 22.9% decline that would have reduced a $1,000 stake to about $771. Gold briefly hit an intraday high of $5,589 on Jan. 28 and traded near $4,500 by May 20, a roughly 6.5% gain for the year. Silver rose about 3.4% after an early-year spike subsided.

Commodities tied to industrial demand showed larger moves. Brent crude climbed from about $60.59 a barrel to near $113, an increase of about 86% that coincided with geopolitical tensions in the Strait of Hormuz in April. Copper gained about 42% on the London Metal Exchange, supported by demand for data-center equipment and electric-vehicle production.

Market activity during the period included a shift of capital toward suppliers of AI infrastructure hardware rather than some of the best-known AI software names. Nvidia lagged some sector peers, and Microsoft traded below its opening price for the year through May 20. The performance through May 20 reflected concentrated gains among a small group of AI-related suppliers alongside more modest returns or declines across other asset classes.
