Adoption

5 medium confidence

5.0

~420M monthly active users across all Copilot surfaces (Windows/Edge/M365/Bing/mobile) reported Q1 2026, with ~160M enterprise-licensed; far above the >10M threshold. Actively-engaged M365 seats are much lower (~33M), but the consumer + embedded surface reach is mass-market. Headline aggregated figure traces to Microsoft disclosures via aggregators; primary per-surface breakdown not directly fetched, so medium confidence.

Capability

4 medium confidence

4.0

Feature-rich chat UI with class-leading enterprise grounding/integration; not frontier-defining within this category because it is locked to one model provider and not self-hostable.
