Microsoft’s AI Bet Fuels Growth as $190 Billion Buildout Tests Investors

Overview

• Microsoft reported quarterly revenue of $82.9 billion as Azure grew 40% year over year and its AI business topped a $37 billion annual run rate, up 123%.
• Enterprise use is broad with more than 20 million paid Microsoft 365 Copilot seats, nearly 90% of the Fortune 500 building agents in Copilot Studio, and tens of thousands of organizations managing tens of millions of agents through Agent 365.
• The company guided about $190 billion in capital spending this calendar year for AI data centers, with roughly $25 billion tied to higher memory and GPU costs that some investors view as a margin headwind.
• Profitability stayed strong in the latest quarter with a 46.3% operating margin, $38.4 billion in operating income, and $31.8 billion in net income.
• Investor reactions are split as hedge fund TCI cut most of a roughly $8 billion stake citing AI uncertainty, while Wedbush kept an Outperform rating with a $575 target and Grok’s model portfolio ranked Microsoft as its top holding.
