GitHub Copilot Surpasses 20 Million All Time Users

GitHub Copilot has surpassed 20 million all-time users, marking a major milestone for the AI coding assistant, according to Microsoft CEO Satya Nadella and confirmed by GitHub to TechCrunch. The service added 5 million users in just three months, up from 15 million reported in April 2025.

Copilot’s adoption continues to accelerate within the developer ecosystem, with 90% of Fortune 100 companies now using the tool. Enterprise usage jumped 75% quarter-over-quarter as companies seek productivity gains, streamlined code reviews, and improved security testing—areas where Copilot’s AI-driven features and compliance tools give it an edge.

Nadella told investors that Copilot is now a larger business than GitHub was at the time of Microsoft’s 2018 acquisition, underscoring the growing impact of AI in developer workflows. While Copilot’s user base lags behind consumer-facing chatbots like ChatGPT or Gemini, its focus on professional software engineers has proven a bankable niche.

The competitive landscape is heating up. Cursor, a rising rival, claims more than $500 million in annual recurring revenue and over 1 million daily users as of March. Both GitHub Copilot and Cursor are expanding their AI-driven offerings, including agents that automate code reviews and workflow integrations, in a race to capture the enterprise market.

Microsoft and GitHub plan to push Copilot’s feature set further, doubling down on AI as an integral part of modern software development. The company’s growth trajectory suggests AI coding assistants are quickly becoming standard issue in the developer’s toolkit.
