GitHub's Octoverse 2026 shows merged pull requests tripled to 220 million per month

GitHub's Octoverse 2026 report, announced by EVP Jay Parikh, says merged pull requests tripled in less than a year to 220 million per month, and commits more than tripled to 7.38 billion per month, with most of that rise in the second half of the year.

New repositories doubled to 30.3 million per month. Parikh calls the figures a stark representation of the impact of agentic engineering on GitHub.

A separate X post by Rohan Paul says GitHub recorded 7.38 billion commits in September 2026, more than five times the figure a year earlier. The post says GitHub has added 4 million CPU cores, 160 PB of high-speed storage and 50 Tb/s of network capacity this year to handle agent-written code. It also cites a 7-hour-47-minute outage on August 17 and says a multi-region Azure migration is expected to finish early next year.

The commit figures differ between the two sources: Octoverse gives a monthly average that more than tripled, while the X post gives a September figure more than five times the prior year.
