Anthropic in Advanced Talks to Buy Developer Tool Startup in First Acquisition

Anthropic is in advanced discussions to buy Bun, a maker of software used to run and manage code more efficiently, according to a person with knowledge of the deal. The artificial intelligence company is in talks to pay in the low hundreds of millions of dollars for the startup, which would be Anthropic’s first acquisition, according to the person.

The acquisition would give Anthropic, which already has been using Bun for over six months, direct access to the startup’s expertise and further boost the performance and stability of its coding agent Claude Code. The software would also help business customers set up Claude Code more efficiently. Annualized revenue from the agent hit $1 billion last month, according to the person.
