Quick overview

SanDisk Corporation (NASDAQ: SNDK) has been one of the absolute wildest stories in the market. After spinning off from Western Digital ( WDC ) in early 2025 at around $38.50 per share, it became the best-performing stock in the S&P 500 for the first half of 2026, peaking at an all-time high of $2,354.39 —an astounding rally of over 700% year-to-date.

 Investors are cashing in massive gains after a meteoric 800%+ run over the past year. The entire memory chip sector pulled back sharply alongside SanDisk—its rival Micron ( MU ) plummeted over 9%, and Seagate ( STX ) dropped nearly 10%.

Capital is temporarily shifting out of hardware/chip manufacturing stocks and flowing into AI software applications. Furthermore, Meta’s reported building of its own AI cloud infrastructure has rattled pure-play memory vendors.

 The 14% drop occurred on the exact day SanDisk and its partner Kioxia announced a massive manufacturing milestone: they began mass production of their next-generation 10th-generation 3D Flash memory at the Fab2 (K2) plant in Japan. The market completely ignored this fundamental win on valuation cooling.

Despite the severe pullback, institutional analysts remain incredibly bullish on SanDisk’s  AI ​​infrastructure boom. Every AI server requires massive high-speed storage, pushing contract pricing for NAND flash memory straight up through 2026.

: In its most recent fiscal Q3 report, revenue rocketed 251% year-over-year to $6.0 billion, while gross margins exploded to 78.4% due to tight global supply.

: Wall Street holds a consensus “Strong Buy” rating. Bernstein recently made headlines by raising its target to $3,000, highlighting SanDisk’s superior downside contract protection over Micron. Bank of America and Citigroup maintain aggressive targets at $2,500.

: Because the share price has passed the $1,700–$2,000 threshold, there is heavy market chatter that management may introduce a significant stock split before the end of 2026 to make shares accessible to retail investors again
