Annual Paid AI Subscriber Growth

The AI Behavior Index is the research arm of OneChat AI. This page focuses on paid subscriber counts for the major consumer AI products — distinct from total monthly active users (which include free-tier users and product integrations) and from enterprise API revenue (which is metered, not subscription-based).

An important caveat for anyone citing this data: most companies in this market do not publish exact paid subscriber counts. OpenAI is the most transparent and reports paid totals across its tiers periodically. Anthropic confirms growth rates (e.g., "paid subs more than doubled") but does not disclose absolute numbers. Google reports Gemini subscription revenue ($1.2B in 2025) but not subscriber counts. Microsoft reports total Copilot users but blurs the line between voluntary paid subscribers and M365-bundled access. Where this page reports non-OpenAI estimates, the figures are derived from third-party surveys (Recon Analytics), public revenue disclosures, and credit card transaction studies. Margin of error on non-OpenAI estimates is approximately ±25%. Data is refreshed quarterly. If you have a study to suggest or notice an error, contact us at research@aibehaviorindex.org.
