Strategic Rationale
Announced alongside Claude Code crossing $1B run-rate revenue six months after launch. Bun is the fast all-in-one JavaScript runtime (7M+ monthly downloads, 82k+ GitHub stars) that underpins Claude Code, so the deal vertically integrates critical agent infrastructure. Bun remains open source under the MIT license.
