Microsoft Corporation Q3 2026 Earnings Recap

• AI-related annualized revenue exceeded $37 billion, up 123%.
• Management emphasized aggressive additions to data center capacity and highlighted plans to double their footprint in two years, suggesting ongoing elevated capital intensity.
• Operational gains included a 20% reduction in GPU lead times and 40% throughput improvement in major Copilot AI models.
