SanDisk Corporation (NASDAQ: SNDK) reached a market capitalization of $265.98 billion on Wednesday, October 15, 2026, surpassing its former parent company Western Digital amid surging artificial intelligence infrastructure demand.
### Tape / Session Read SanDisk closed at $1394.83 on October 15, logging a 51.07% return over the prior six months. The equity has advanced 901.24% over a twelve-month horizon, fueled by high-capacity flash memory utilization in data centers training artificial intelligence workloads. Quarterly revenue expanded 371.6% year-over-year, leaving operating profit at 78.47% of revenue.
### Why This Lane Matters The valuation flip highlights how pure-play component suppliers serving artificial intelligence infrastructure can re-rate faster than legacy diversified hardware structures. While the parent company retained a thriving hard drive business, the flash memory segment captured heavier institutional capital flows.

Market participants must assess whether 78.47% operating margins can weather a full industry cycle.
