GitHub Copilot just crossed 20 million users. Five million joined last quarter alone. Enterprise usage? Up 75% quarter-over-quarter. It’s now in the hands of 90% of the Fortune 100, according to Microsoft.

Here’s the kicker: Copilot’s AI coding biz is now bigger than all of GitHub’s revenue when Microsoft bought it in 2018.

Big picture: These tools aren’t just autocomplete anymore. They’re creeping deeper into the stack—writing code, reviewing it, automating full workflows. The dev pipeline’s changing fast.
