Microsoft Faces Class Action Over Azure Growth and AI Spending

Shareholders filed a class-action suit in Seattle federal court alleging Microsoft concealed a slowdown in Azure and the scale of AI-infrastructure spending. The complaint is led by the City of St. Clair Shores Police and Fire Retirement System, a Michigan pension fund, and names CEO Satya Nadella, CFO Amy Hood, and executives as defendants. The class period runs May 1 2025 – Jan 28 2026.

Microsoft Sued Over AI-Related Cloud Spending

In fiscal Q2 ending Dec 2025, Microsoft reported Azure and other cloud revenue growth of 39 %, down from 40 % the prior quarter and below its guidance of 37-38 % for the next quarter. Capital spending rose to $37.5 bn, a 66 % YoY increase that topped analysts’ $34.3 bn forecast. The outlay funds GPUs, custom chips, data-center capacity for large-language-model training, and development of Copilot and the OpenAI partnership, implying an annualised AI-infrastructure run rate of roughly $37 bn for FY 2026.

Plaintiffs argue Microsoft amplified its AI narrative to distract investors from a decelerating Azure business and rising infrastructure costs, claiming the firm downplayed the financial burden of GPUs, custom chips and data-center expansion while overstating Copilot and OpenAI benefits.
