SanDisk Tops 2026 Returns After 509% Rally

SanDisk shares climbed 509% between Jan. 1 and May 20, making the company the best-performing asset of 2026 so far. A $1,000 investment on Jan. 1 would be worth about $6,090 as of May 20. The rally coincided with rising demand for memory chips used by cloud data centers that train large AI models.

In its April 30 earnings release, SanDisk reported quarterly revenue of $5.95 billion, a 251% increase from a year earlier, and disclosed a $42 billion order backlog from cloud customers. The stock reached an all-time high of $1,562 on May 8 and traded near $1,383 on May 20, more than 11% below that peak.

SanDisk outperformed other assets tracked through May 20. A crypto token, DeXe, was up about 363%, Intel rose 209% and Seagate gained 183%. Bitcoin fell about 22.9%, sliding from roughly $87,600 at the start of the year to about $76,800.

Commodities showed varied results. Brent crude rose from $60.59 a barrel to near $113, an 86% increase after tensions around the Strait of Hormuz in April. Copper on the London Metal Exchange climbed about 42%. Silver was up roughly 3.4%. Gold briefly hit a record $5,589 on Jan. 28 and later traded near $4,500, leaving about a 6.5% gain year to date.

Major U.S. equity indexes delivered smaller gains. The Nasdaq 100 rose about 16%, the S&P 500 about 9.1% and the Dow Jones Industrial Average roughly 3.9%. Trading activity showed increased buying in suppliers of AI infrastructure such as SanDisk, Intel and Seagate rather than in the most visible AI software and chip designers.

SanDisk makes flash memory and storage products for cloud providers and data centers used in large-scale AI training and inference. The company’s reported revenue growth and its $42 billion cloud backlog were included in investor assessments of the stock. The price history through May 20 included sharp intraday and weekly swings and a pullback from the May 8 high.
