Micron Shares Surge on Blockbuster Earnings Driven by AI Chip Demand

Micron Shares Surge on Blockbuster Earnings Driven by AI Chip Demand Micron’s latest earnings have turned a once-cyclical memory maker into a central protagonist of the AI boom, igniting a market frenzy while raising questions about how long the surge can last.

Early signs: AI memory crunch turns into a windfall

By late June, Micron reported fiscal third-quarter revenue of nearly $42 billion, quadrupling year-over-year as AI demand sent gross margins above 81%. Profits jumped from about $1.9 billion to more than $28 billion over the same period, a roughly 15-fold surge as AI companies clamoured for chips. One report framed it simply: the “memory chip crunch is paying off for this US company.”

The boom stems from a severe shortage of high-bandwidth memory (HBM) and other DRAM and NAND chips needed to run large AI models. HBM has become the “binding constraint” on AI infrastructure, with Micron one of only three suppliers globally.

Market reaction: Wall Street’s next Nvidia?

The blockbuster results triggered an immediate share rally, with Micron’s stock jumping in after-hours trading on expectations of sustained memory demand. Within days, the company’s market value briefly hit about $1.27 trillion, surpassing Meta and Tesla, as the stock soared more than 236% in a month. Analysts have begun asking “Why Wall Street Thinks US Memory Maker Micron Is the Next Nvidia,” noting that revenue quadrupled to $41.45 billion and profits to $28.2 billion as the AI data center buildout intensified.

Micron’s guidance reinforced the optimism: it projected fourth-quarter revenue of around $50 billion and lifted full-year capital spending above $25 billion to expand advanced memory capacity.

Wider impact: from Apple to AI labs

The same chip crunch is rippling through consumer tech. Apple has linked price rises to the “unprecedented” cost of memory chips, while AI labs like Anthropic are signing multi-year supply deals as part of Micron’s 16 strategic agreements aimed at smoothing out the industry’s historic boom–bust cycles.

Whether Micron’s meteoric rise proves durable now hinges on how long “RAMageddon” lasts—and whether new capacity arrives before the AI memory shortage eases.
