Micron Jumps on GPT-6 AI Memory Boom Ahead of Earnings

Micron Technology rallied about 4.2% to roughly $999 as OpenAI’s GPT-6 Astra launch rekindled AI-memory demand, boosting the stock’s 2026 gain to about 236% and lifting its market cap near $1.14 trillion. In fiscal Q3, revenue was $41.46 billion with adjusted free cash flow of $18.3 billion; cloud-memory ($13.77B) and data-center ($11.52B) combined accounted for about 61% of revenue. The shares trade roughly 61% above GuruFocus’ GF Value, suggesting AI-driven growth is already priced in, though September 30 earnings will test whether orders, pricing, and cash flow can sustain the rally, especially if GPT-6-related memory demand proves durable.
