Sandisk (NASDAQ: SNDK) stock, in its latest iteration, has been among the top-performing assets of 2025, as, at its initial public offering (IPO) in February of the previous year, the company was being sold at $38.50, while, at press time on January 28, 2026, Sandisk stock is trading at $508.
Such a staggering, 1,219% rise not only took the company’s market capitalization from about $6.7 billion to above $70 billion, but also means that an investor who chose to buy $1,000 worth of SNDK shares during the IPO would have made $12,190 in profits.
Additionally, even if only Sandisk stock’s latest closing price of $481.43 is accounted for – SNDK rallied another 5.52% in the extended session between January 27 and January 28, 2026 – such an investor would have $12,500 worth of the firm’s shares, meaning they would have made a profit of $11,500.
Why Sandisk stock rallied more than 1,200% in less than a year
Sandisk is a company with an old pedigree, having been founded in 1988. Despite this, it has, in its current iteration, spent less than a year in the stock market as it was acquired by Western Digital (NASDAQ: WDC) in 2016 and finally spun off once again in February, 2025.
As a company, Sandisk specializes in flash memory and has been separated from its parent company in order to make a clear distinction between the manufacturers of that type of storage and Western Digital’s main lineup of hard drives.
A large part of SNDK’s rally can be traced to the current drive to scale up digital infrastructure amidst the ongoing artificial intelligence (AI) boom, and, indeed, the company revealed in November 2025 that it is working with ‘five major hyperscale customers.’
