GitHub's record June shows usage-based pricing is the unlock enterprise AI has been waiting for

GitHub's CTO Vladimir Fedorov told employees June 2026 was the platform's best month ever after Copilot's switch to usage-based billing on June 1 unlocked enterprise AI spend. The surge also broke GitHub's infrastructure badly enough that Microsoft had to provision capacity from AWS, logging nine service incidents in May and falling below its 99.9% enterprise SLA in June. Over 51% of code committed to GitHub is now AI-assisted.
