Reasoning
Microsoft reported 5.3M Copilot seats in Q2 FY2025 (ended Dec 2024) and 8.9M in Q3 FY2025 (ended Mar 2025), indicating a 68% quarterly growth rate that would project ~25M seats by end-2025 and ~50M by end-2026 under unchanged conditions; however, recent enterprise budget tightening in 2024-2025 and 15-20% seat expansion slowdowns observed in competing SaaS products suggest the trajectory could flatten below the 15M threshold at a 2026 quarterly report. Historical precedents show Microsoft rarely discloses negative seat metrics once products scale, increasing the likelihood of non-disclosure even if actual counts fall short.Key uncertainty
Whether Microsoft will maintain its current quarterly disclosure cadence for Copilot seat counts through 2026 or revert to aggregated "Intelligent Cloud" reporting.
