• AI adoption drives soaring demand and prices for memory and storage.
• Sandisk's market cap rose from $5.6B to $40B in ten months after its spinoff.

Wall Street's hot corner in the last one year was an old fashioned part of the technology industry.

Sandisk and other storage-focused companies are among the “key beneficiaries” of the growing adoption of artificial intelligence inferencing and edge AI, Bank of America analysts led by Wamsi Mohan said in a client note dated January 4. Mohan said organisations are retaining larger volumes of data for AI training, analytics and regulatory compliance, driving a sharp rise in storage demand. He pointed to increasing use across applications such as drones, surveillance systems, vehicles and sports technology.

Memory prices have been on a steady upward trajectory. Korea Economic Daily reported earlier this week that Samsung Electronics and SK Hynix are seeking to raise server DRAM prices by 60% to 70% in the first quarter compared with the previous quarter.

Against this backdrop, Sandisk emerged as the top-performing stock in the S&P 500 in 2025 and has gained 48% so far in 2026.

Western Digital acquired Sandisk for $16 billion in 2016 and spun it off as a separate company in February 2025. At the time of the spinoff, Sandisk debuted at $38.50 per share, valuing the company at $5.6 billion, a 65% discount to the original acquisition price. Ten months later, Sandisk’s market capitalisation has climbed to about $40 billion.

Industry research firm IDC has described the current environment as a “memory shortage crisis,” noting that this is the first time in three decades that DRAM, NAND and hard disk drives have all been constrained simultaneously.

NAND wafer prices surged 60% in November alone, while contract prices have doubled since July. Suppliers are already sold out through 2026 and are negotiating allocations for 2027. Samsung has raised flash memory prices by about 60% since September, while Micron has presold nearly all of its high-bandwidth memory output through 2026. TrendForce estimates demand for memory will rise 20–22% in 2026, outpacing supply growth of 15–17%.

Sandisk shares jumped 28% on January 6, marking their biggest single-day gain since February, after Nvidia Chief Executive Officer Jensen Huang underscored the importance of memory and storage at the CES technology conference. An investor who purchased $10,000 worth of Sandisk shares at the time of the spinoff would now be holding an investment valued at roughly $90,000.

“For storage, that is a completely unserved market today,” Huang said at the event, adding that the sector could become the largest storage market globally as it holds the working memory of artificial intelligence systems.

Tight supply conditions and rising prices, combined with expanding demand for AI training and inferencing, are supporting gains in digital storage stocks, Bloomberg Intelligence analyst Jake Silverman said. Huang’s remarks suggest that demand for NAND storage will remain strong across Nvidia’s systems, he added.

Sandisk has also been gaining market share, increasing its share of the NAND market by two percentage points over the past 12 months, while rivals including Samsung, SK Hynix and Kioxia have ceded ground.
