GitHub Copilot, the AI-powered coding assistant developed by GitHub, a Microsoft-owned company, has surpassed the milestone of 20 million users globally. Microsoft CEO Satya Nadella announced the figure during the company’s recent earnings call, with GitHub later confirming that the number represents all-time users since the tool’s launch. Notably, five million users joined in the past three months alone, up from 15 million reported in April.

Widespread Adoption Across Enterprises

GitHub Copilot continues to gain traction among large organizations, with Microsoft revealing that 90% of Fortune 100 companies now use the tool. Enterprise adoption has grown by approximately 75% compared to the previous quarter. This growth reflects a broader trend in which AI coding tools are becoming a key part of modern software development, particularly in corporate settings.

Copilot Now Outpaces GitHub’s Business in 2018

In a notable benchmark, Nadella shared that GitHub Copilot has now become a bigger business than GitHub was in its entirety when Microsoft acquired it in 2018. This highlights the increasing commercial value of AI-driven development tools. Though Copilot's user base remains small compared to general AI chatbots like ChatGPT, its niche audience of software developers is more likely to pay for premium functionality.

Rising Competition from Cursor and Others

While GitHub Copilot leads the enterprise AI coding market, competition is intensifying. Cursor, another fast-growing tool, reportedly surpassed one million daily users in March and now generates over $500 million in annual recurring revenue. Both GitHub and Cursor have recently introduced AI agents to streamline coding tasks, reduce human error, and automate workflows, signaling a future where AI tools take a central role in development teams.

With more companies entering the AI coding space and the demand for intelligent development tools rising, GitHub Copilot’s early lead and strong enterprise integration could help it remain a dominant force in this evolving market.
