A $35,000 investment in SanDisk one year ago would be worth over $1 million today, as the data storage company rides a massive wave of demand from the artificial intelligence industry.

SanDisk stock soars 2700% in a year on AI data demand
The race to build powerful artificial intelligence has created an insatiable appetite for data storage, catapulting SanDisk’s stock over 2700% in a single year and turning a $35,000 investment into $1 million. The surge reflects a dramatic market shift, with the company set to join the NASDAQ 100 on April 20, replacing software firm Atlassian.
"This is a market that never existed, and this market will likely be the largest storage market in the world, basically holding the working memory of the world's AIs," Nvidia CEO Jensen Huang said in January, calling AI data storage a "completely unserved market." SanDisk's stock jumped 28% in a single day following his comments.
The data storage giant’s stock has far outpaced the S&P 500’s approximate 30% gain over the last year, and has dwarfed returns from tech titans like Google (+115%), Microsoft (+12%), and even AI-darling Nvidia (+90%). SanDisk’s performance also topped storage-sector competitors, including Seagate Technology (+605%) and its former parent company, Western Digital (+922%). The sector-wide boom has also lifted Micron Technology, which saw its stock hit a 52-week high in mid-March.
This rally marks a stunning reversal of fortune. Just two years ago, the data storage industry was unprofitable after companies over-bought during the cloud computing buildout. SanDisk was spun out of Western Digital in February 2025 to separate the high-demand flash memory business, which provides instantly accessible "hot" storage for active AI models, from the legacy hard drive "cold" storage business. That move positioned SanDisk perfectly for the AI boom, which has flipped the market from oversupply to a severe shortage, giving SanDisk the power to increase its price-per-bit by over 100% in the last year.
The financial impact is stark. For the quarter ending in December 2025, SanDisk reported revenue of $3 billion, a 61% year-over-year increase, and net income of $803 million, a staggering 672% rise from the same period a year earlier. The company's market capitalization has ballooned from around $5.5 billion a year ago to $135 billion today.
Investors will be watching closely when SanDisk reports its next quarterly earnings on April 30. While optimism is high, some analysts question the sustainability of the explosive growth, pointing to the industry's historically cyclical nature. "We doubt that 'this time is different’,” wrote Morningstar analyst William Kerwin. “We believe Sandisk is prone to market-driven cyclicality in memory chips and doesn’t hold pricing power over its customers.” The upcoming report will be a key test of whether the AI-driven demand can create a new, sustained growth cycle or if the industry is heading for another oversupply cliff.
