GitHub Copilot Surpasses 20 Million Users, Now Used by 90% of Fortune 100

GitHub Copilot, the AI-powered coding assistant from Microsoft-owned GitHub, has surpassed 20 million users, CEO Satya Nadella announced during the company’s earnings call. The figure represents all-time users, meaning five million new users have tried Copilot in the past three months alone—up from 15 million reported in April.

While Microsoft hasn’t disclosed how many of those users are active monthly or daily, the tool’s enterprise adoption is booming. GitHub Copilot is now used by 90% of the Fortune 100, and enterprise usage has surged 75% compared to last quarter.

"This past year, we shipped over 230 updates to GitHub Copilot – becoming the first multi-model solution at Microsoft, in partnership with Anthropic, Google, and OpenAI. We enabled Copilot Free for millions and introduced the synchronous agent mode in VS Code, all the way to Spark and the coding agent native to GitHub," GitHub CEO Thomas Dohmke, said.

GitHub Copilot has crossed 20 million users – up more than 5 million from last quarter. We’re also seeing explosive AI growth on GitHub, with AI projects more than doubling over the past year. And it’s all because of grit. It’s no secret the market Copilot introduced has heated up. Over the past year, incredible startups and founders have built and scaled great products that found real traction. The true measure of a company is never drawn during its hype wave, but by its resilience when pressure tested. Hubbers across GitHub put their heads down, treated pressure as a privilege, and we innovated. This past year, we shipped over 230 updates to GitHub Copilot – becoming the first multi-model solution at Microsoft, in partnership with Anthropic, Google, and OpenAI. We enabled Copilot Free for millions and introduced the synchronous agent mode in VS Code, all the way to Spark and the coding agent native to GitHub. I could not be more proud of my colleagues. Even with all the constraints we’ve faced, we proved that a little grit wins the game. | 27 comments on LinkedIn

AI coding tools like Copilot are among the few generative AI products generating meaningful revenue. In 2024, Nadella said Copilot had already become a bigger business than GitHub was at the time of its 2018 acquisition.

Earlier this year, GitHub open-sourced its Copilot Chat client for Visual Studio Code, making the codebase freely available under the MIT license.

The move opens the door for developers to explore, modify, and contribute to the Copilot Chat experience—marking a significant step toward greater transparency and community collaboration in AI-assisted coding.
