SanDisk Up 558% This Year as Chip Stocks Outpace the 1999 Dot-Com Bubble

"SanDisk is up 558% this year, supplying NAND flash memory to AI data centers. Unlike many speculative bubbles, the business fundamentals behind the move have also accelerated dramatically. Q3 FY26 revenue reached $5.95 billion, up 251% year over year, while the company's Datacenter segment alone grew 645% YoY to $1.467 billion. CEO David Goeckeler described the moment as "a fundamental inflection point" during the company's Q3 release."

"Intel is up 239%, with the foundry bet paying off. The semiconductor slice of the S&P 500 has added roughly $3.8 trillion in market cap over the past six weeks. The top 10 performers in the Nasdaq 100 over the past year are up an average of 784%. At the March 2000 dot-com peak, the comparable top 10 were up an average of 622%."

"By that yardstick, the current run is objectively more extreme than the bubble that preceded the 42.22% Nasdaq 100 collapse between January and March 2000. The bull case says this time is fundamentally different. Unlike many dot-com companies, the leaders of today's AI infrastructure rally are producing massive and rapidly growing cash flows."

"Micron Technology went from $15.5 billion in 2023 revenue to an expected $107 billion in 2026. Q1 FY26 alone delivered $13.643 billion in revenue, up 56.6% YoY, with Cloud Memory at a 66% gross margin. AI agents working continuously require enormous amounts of memory, which is why both"

Semiconductor chip stocks have experienced a major rally in 2026, with price performance exceeding the 1999 dot-com bubble by raw measures. SanDisk has risen 558% this year, supported by accelerating fundamentals, including Q3 FY26 revenue of $5.95 billion and Datacenter segment growth to $1.467 billion. Intel has gained 239% as its foundry strategy has paid off, while the semiconductor portion of the S&P 500 has added about $3.8 trillion in market cap over six weeks. Comparisons to 1999 show the top Nasdaq 100 performers rising more on average than at the dot-com peak. The bull case centers on AI infrastructure companies generating large, rapidly growing cash flows and revenue, including Micron’s projected jump from 2023 revenue to 2026 revenue.
