SanDisk’s SNDK has delivered one of the most explosive AI infrastructure rallies on the market, rising from its April 2025 low near $27.89 to a June 2026 intraday high above $2,021. That move works out to a gain of more than 7,100% from low to peak in roughly 14 months, turning SanDisk from a newly independent flash-memory company into one of Wall Street’s most aggressive AI hardware trades. Latest SNDK market data showed the stock closing at $1,980.10 on June 12, up 5.24% on the day, after trading as high as $2,021.65.
