SanDisk secured a $42 billion order backlog as the artificial intelligence boom drives memory chip demand. The company reported its entire 2026 enterprise AI storage capacity is sold out under long-term agreements. These factors established the firm as a top S&P 500 performer in 2026.
The stock recently experienced a sharp pullback from its peak despite the record backlog. Broader semiconductor sector concerns regarding high valuations and AI demand sustainability triggered the volatility. Investors are currently weighing guaranteed future revenue against the cyclical nature of the memory market and rising competition.
