Shares jumped after Microsoft reported stronger-than-expected quarterly profit, strong Azure cloud growth, and no large incremental AI capex surprise, helping revive the AI trade. Mega-cap software led the whole tape; the move was large enough to add roughly hundreds of billions in market value and pull AI infrastructure beneficiaries higher.

Lam Research Corporation (LRCX) +17.98%

Lam rallied after fiscal-quarter profit and revenue beat expectations and AI-related wafer-fab-equipment demand supported stronger guidance. A major semiconductor-capex bellwether posted one of the day’s biggest large-cap operating-company gains.

Meta Platforms, Inc. (META) -7.95%

Meta fell after reporting weaker profit than expected and raising the lower end of its investment-spending forecast, sharpening investor concern over AI capex returns. The move contrasted sharply with Microsoft’s rally and framed the day’s central AI-capex split: spending with visible returns was rewarded, spending without enough proof was punished.

Micron Technology, Inc. (MU) +18.36%

Memory and AI-chip stocks rebounded hard in the wake of Microsoft’s AI/cloud read-through; AP specifically cited Micron as the strongest S&P 500 lift after Microsoft. A massive single-session reversal in one of the most liquid AI-memory names after a sharp multi-day semiconductor selloff.

Advanced Micro Devices, Inc. (AMD) +13.00%

A top liquid AI accelerator supplier reversed sharply before its own earnings, underscoring the sensitivity of chip leadership to hyperscaler capex read-throughs.

IREN Limited (IREN) +30.54%

High-beta AI-cloud and data-center infrastructure shares rebounded with the AI trade; IREN’s company-specific backdrop included recent AI cloud contracts and NVIDIA-linked infrastructure expansion plans. A large-capitalization former bitcoin-mining name turned AI-infrastructure proxy produced one of the day’s biggest liquid operating-company moves.

Intel Corporation (INTC) +11.30%

Intel participated in the broad semiconductor rebound tied to Microsoft’s stronger cloud outlook and the recovery in AI-related chip names. The stock was among the most actively traded U.S. operating-company shares on the session and showed that the rebound extended beyond the pure AI winners.

Amazon.com, Inc. (AMZN) +3.90%

Amazon advanced with the broad megacap tech rebound ahead of its after-close earnings report; no intraday/premarket figures were used. Even a sub-4% move in Amazon was material because of the stock’s size and heavy volume, and it sat at the center of the post-close megacap earnings setup.
