GitHub's June Usage Surge After Copilot's Usage-Based Pricing Shift

GitHub's CTO Vladimir Fedorov reported that June 2026 was the platform's most successful month to date, attributing the surge to the shift to usage-based billing for GitHub Copilot. This change, implemented on June 1, has evidently stimulated enterprise AI adoption and expenditure.

The new pricing structure for Copilot Business customers includes a $19 monthly fee per user with $19 in AI Credits, while Copilot Enterprise costs $39 per user per month with $39 in credits. Additionally, business customers received an extra $30 in monthly credits for June, July, and August, and Enterprise customers received $70. Importantly, included usage credits are now pooled across a business, preventing unused credits from being trapped.

This shift in pricing model has demonstrated that once AI coding becomes an integral part of daily infrastructure, flat-rate plans no longer align with the actual cost or demand. The increased usage, however, also strained GitHub's infrastructure, requiring Microsoft to provision additional capacity from AWS and resulting in nine service incidents in May and falling below its 99.9% enterprise SLA in June.

Despite the infrastructure challenges, the data clearly indicates a significant acceleration in AI-assisted coding, with more than half of all code committed to GitHub now benefiting from AI assistance.
