Anthropic Acquires Bun JavaScript Runtime as Claude Code Hits $1B ARR
Anthropic has acquired Bun, the high-performance JavaScript runtime and all-in-one toolchain founded by Jarred Sumner in 2021, to accelerate Claude Code's infrastructure. Claude Code reached $1 billion in annualized run-rate revenue in November 2025, just six months after its May 2025 general availability launch. The acquisition deepens an existing partnership—Bun was already integral to Claude Code's infrastructure scaling and its native installer launch. Bun will remain open source and MIT-licensed, with Anthropic committing continued investment in the project.
