Micron Surges 13% as CoreWeave Earnings Revive AI Trade and Anthropic IPO Adds Catalyst

Micron Technology shares jumped roughly 13% on November 11, its best single-day gain since July, reversing a slide that had erased nearly 30% of its value over the prior month. The rally was sparked by CoreWeave's third-quarter earnings beat, in which the cloud infrastructure company reported revenue of $3.66 billion, up 168% year over year and above Wall Street estimates of roughly $3.55 billion, then raised its full-year 2026 revenue guidance to $13.3 billion. CoreWeave's CEO said AI demand continues to outpace the world's capacity to supply computing power, calming fears that had weighed on memory and chip stocks for weeks. The broader AI rally added approximately $1.2 trillion to the US stock market, with Sandisk gaining 17%, Seagate rising 12%, SK Hynix climbing 11%, and Nvidia recovering about 4%.

A second catalyst for Micron was confirmation of its $1 billion participation in a $26 billion private placement tied to Anthropic's IPO. The placement brings together Nvidia and Alphabet at $10 billion each, AMD at $2.5 billion, Broadcom and Microsoft at $1 billion each, and TSMC at $500 million. Anthropic is marketing 825 million shares at $70 to $78, targeting a valuation of $1.25 trillion to $1.4 trillion and up to $64.35 billion in IPO proceeds, with pricing expected during the week of November 16.

Fundamental disclosures reinforced the bull case. Micron has secured 26 multi-year take-or-pay contracts covering more than 35% of revenue through 2030, providing a stable earnings floor across market cycles. Over 75% of its 2027 output is already committed, and supply constraints are expected to persist. Fourth-quarter 2026 revenue surged 379% year over year to $54.23 billion with gross margins of 87%. Separately, Netlist announced it anticipates $73 million in combined quarterly licensing revenue, supported by Micron payments beginning in Q4 2026. Analysts at Bernstein argued the stock could nearly double from recent levels, while analysts at Seeking Alpha's Quant system placed Micron at the top of semiconductor rankings. Goldman Sachs, however, said memory chip rivals may offer better near-term value, and Bank of America removed Micron from its US 1 List of top investment ideas, though it kept its Buy rating, characterizing the move as a conviction reallocation rather than a downgrade. HBM repricing expected in 2027 is seen as a further catalyst to narrow the profitability gap between HBM and standard DRAM and boost margins.
