Microsoft's valuation soared by $450 billion in a single day, the largest one-day jump in U.S. stock market history, surpassing the entire stock market capitalization of Turkey ($404 billion) and Poland ($316 billion). The surge followed an earnings report showing $90 billion in quarterly revenue, an 18% increase, and Azure cloud revenue surpassing $100 billion for the first time in fiscal year 2026. CEO Satya Nadella highlighted customer confidence in Microsoft's AI transformation. The company plans to invest $175 billion in AI capabilities in 2026 and added 31 data centers across five continents in the past quarter, bringing its total to 88. Analysts expect $95 billion in revenue for the next quarter. The rally nearly erased Microsoft's earlier 2026 losses, with shares trading around $463, up 19% from before the earnings report.
