The last time I spoke about Sandisk (NASDAQ: SNDK), I said, “As AI data centers rapidly expand across the globe, demand for high-performance storage solutions is surging, putting companies like Sandisk in a strong position for long-term growth. With analysts at major firms issuing bullish price targets, tightening NAND supply, and artificial intelligence infrastructure spending accelerating, Sandisk is emerging as a top technology stock to watch in 2026.”
That’s a big part of why the stock is up more than 2,000% in a year.
Supply Cannot Keep Up with Demand
In addition, we also have to consider that artificial intelligence will continue to drive massive demand for data centers, which, in turn, will fuel further demand for NAND.
You see, as long as there’s demand for artificial intelligence and data centers, there will be substantial demand for NAND. We also have to consider that these AI developments are happening with a supply backdrop that was never really designed to keep up with the demand it’s creating. That’s why NAND supply growth will remain limited in the immediate term.
In addition, consider this.
There are about 4,000 operational data centers in the U.S. right now. An additional 1,500 to 3,000 are being planned or under construction. According to Pew Research, the South has 754 planned data centers. The Midwest has 419 planned. The West has 277 planned, and the Northeast has about 106 planned. Globally, there are about 10,807. All need NAND, which creates even more opportunity.
AI Is Creating Significant Demand for Memory
When people think about AI, they often think about companies like Nvidia that make powerful graphics chips. But AI systems need much more than processors. They also need massive amounts of memory to store and move data quickly.
This is where Sandisk comes in. The company makes NAND flash memory, a type of storage used in solid-state drives (SSDs), laptops, smartphones, data centers, and AI servers. As AI applications become larger and more complex, companies need more high-speed storage than ever before. That surge in demand has made memory chips much more valuable.
A Memory Shortage Helped Prices Rise
Demand is only one side of the story. At the same time, memory manufacturers have been careful not to flood the market with too much supply. After several difficult years, companies reduced production and focused on improving profits instead of simply making more chips.
Now demand has returned much faster than expected.
This has created a supply shortage, allowing companies like Sandisk to charge higher prices for their memory products. Analysts believe the tight supply could continue for several years if AI demand keeps growing.
Investors Believe AI Spending Is Just Beginning
Big technology companies continue to spend billions of dollars building AI data centers. Every new AI server requires large amounts of memory and storage. If AI investment continues for years, companies like Sandisk could continue seeing strong sales growth.
Wall Street expects the company’s earnings to grow dramatically as demand remains strong. That optimism has encouraged many investors to keep buying the stock despite its already impressive gains.
The Bottom Line For Sandisk
Sandisk’s strong performance has been driven by an unstoppable AI boom, which has dramatically increased demand for memory chips. Limited supply has pushed prices higher. Those factors have now sent the stock more than 2,000% higher in just one year. For long-term investors, the company’s future will likely depend less on its incredible past performance and more on whether demand for AI memory continues growing over the next several years.
