On GitHub, agents kick off four out of ten pull requests
The annual Octoverse report shows an explosion in commits and pushes, with TypeScript as the most popular language and Rust as the fastest grower.
More than 40 percent of pull requests on GitHub in September were started by an AI agent, compared with 17 percent in March. That is according to Octoverse 2026, the annual report GitHub published on 28 October, covering the period from October 2025 to the end of September 2026. In September alone, that amounted to around 110 million pull requests.
Activity on the platform soared: 17.9 billion pushes, more than in 2024 and 2025 combined, and 34.3 billion commits. GitHub Actions ran 45.4 billion jobs. The platform counts more than 225 million developers, with the United States (38.3 million) and India (32 million) as the largest communities. TypeScript has the most monthly contributors, ahead of Python and JavaScript, and Rust grew fastest in percentage terms: its number of contributors roughly doubled.
Security company GitGuardian adds a caveat. GitHub ran 5.8 billion push protection scans against 17.9 billion pushes, which suggests most pushes are not checked by it. GitGuardian also counted a record 28.65 million newly leaked secrets, such as passwords and keys, in public commits on GitHub in 2025.
