Microsoft Shares Down 17% YTD, Faces Surging Capex and AI Funding Pressures
Microsoft shares have plunged 17% year-to-date and trail the S&P 500 by over 30% since August 2025, marking its worst relative performance since 2000 despite 39% Azure revenue growth. Investors are scrutinizing 65.9% capex growth to $37.5 billion and a >$100 billion OpenAI funding round as regulatory and competitive pressures mount.
1. Historic Underperformance
Microsoft's stock has declined 17% year-to-date and has underperformed the S&P 500 by over 30% since August 2025, marking a seven-month relative losing streak not seen since 2000. This downturn makes Microsoft the worst performer among its large-cap peers in 2026.
2. Capex and Growth Dynamics
In the latest quarter, capital expenditures surged 65.9% year-over-year to $37.5 billion, with two-thirds allocated to GPUs and CPUs for Azure cloud services. Azure revenue grew 39% year-over-year, down from 40% growth in the previous quarter, while Microsoft 365 Copilot sales reached 15 million seats, below analyst forecasts.
3. OpenAI Funding Participation
Microsoft is expected to join a funding round for OpenAI projected to exceed $100 billion, which could value the AI developer above $850 billion. The infusion aims to finance new data centers and specialized semiconductors, underscoring Microsoft’s deepening AI infrastructure commitments.
4. Regulatory Scrutiny Over Government Cloud Use
U.S. Immigration and Customs Enforcement more than tripled its data stored on Azure in six months through January 2026, prompting Microsoft to reiterate policies prohibiting mass surveillance and call for clear legal guidelines. Investors will watch for potential regulatory responses and contract reviews in upcoming earnings reports.
