Microsoft Stock Today, November 20, 2025: Anthropic Megadeal, AI Bubble Jitters and Dividend Date Put MSFT in the Spotlight
Microsoft closed Wednesday at $487.12, marking a second straight daily decline and a multi-session pullback from above $500. Premarket trading Thursday showed little change. The stock remains up about 20% for 2025, outpacing the S&P 500. Microsoft’s $3.9 trillion valuation comes as it announces a $30 billion Azure deal with Anthropic and faces renewed AI sector volatility following Nvidia’s earnings.
