Cursor 2.5 Async Subagents: 35% of Cursor's Own Merged PRs Now Written by AI — GitHub Copilot Market Share Collapses 42% to 25%
Cursor's February 2026 release introduced async subagents that spawn nested sub-agents in isolated cloud environments — producing merge-ready PRs with no human intervention. Cursor's own engineering team reports 35% of merged PRs now come from these agents. GitHub Copilot's market share has collapsed from 42% to 25% as Cursor crossed $2B ARR, and Copilot responded by allowing paid users to run Claude, Codex, and Copilot simultaneously on the same issue to pick the best output.
