Microsoft's share price declined 34% from Oct. 28, 2025 through March 27, 2026 as CEO Nadella focuses on Copilot Tasks to regain AI leadership

Microsoft was once the front-runner of the generative AI boom, fueled by a $13 billion OpenAI bet, but that narrative has flipped. CEO Satya Nadella is spending significant time with the team building Copilot Tasks—the company's bet on a true computer-using agent (an AI system that can take independent actions to complete work)—and prototyping with them directly.

Nadella announced in October 2025 that he was stepping back from some commercial duties to focus on AI research, product innovation, and the build-out of AI data centers. The article frames Microsoft's challenge as strategic: whether its AI stack is differentiated enough to defend margins and whether Copilot Tasks can reignite per-seat economics before agentic competitors commoditize the category.

Microsoft shares have become one of the software sector's most prominent casualties in the repricing Wall Street is calling the "SaaSpocalypse"—a repricing of subscription-software multiples in the face of AI coding agents. Microsoft, once positioned as the AI cycle's biggest beneficiary, has shifted to become one of its casualties.
