Micron Technology just posted the kind of earnings report that makes Wall Street analysts double-check their spreadsheets. The memory chipmaker delivered fiscal Q3 revenue of $41.46 billion, blowing past consensus estimates of roughly $35.8 billion and dwarfing the $9.3 billion it reported in the same quarter last year.

That’s not a typo. Revenue more than quadrupled year-over-year. The stock responded accordingly, surging approximately 11-16% after the announcement and dragging the entire semiconductor sector upward with it.

The numbers behind the rally

Micron’s non-GAAP earnings per share landed at $25.11, comfortably clearing the $20.5 to $20.8 range analysts had penciled in. But the forward guidance is what really caught attention.

The company projected Q4 revenue of approximately $50 billion. Wall Street had been modeling around $43 billion. In English: Micron expects to generate $7 billion more in a single quarter than professional forecasters anticipated.

CEO Sanjay Mehrotra didn’t mince words about the supply picture, stating there is “no line of sight” to supply meeting demand before at least 2027. High-bandwidth memory, DRAM, and NAND are all in shortage territory.

The company’s valuation has now crossed the trillion-dollar threshold in 2026, with shares appreciating over 200% year-to-date at certain points.

The ripple effect across tech and crypto

Micron’s blowout didn’t just lift its own stock. Industry peers SanDisk and SK Hynix each recorded gains of around 13% in the aftermath.

The spillover extended well beyond traditional semiconductors. Bitcoin maintained its position above $60,000 during the rally, and AI-linked crypto mining stocks like IREN and CIFR posted moderate gains.

On July 1, Micron also signed a strategic supply agreement with General Motors for next-generation vehicle platforms. The deal underscores how memory demand is broadening beyond data centers into automotive, edge computing, and industrial applications.
