AI startup Anthropic has made its first acquisition, scooping up Bun—the engine behind its fast-growing Claude Code programming agent—the company said Tuesday.
Claude Code is a coding agent that lets developers write, debug and interpret code through natural-language instructions. Claude Code had already hit $1 billion in revenue six months since its public debut in May, according to a LinkedIn post from Anthropic’s chief product officer, Mike Krieger. The coding agent continues to barrel toward scale with customers like Netflix, Spotify, and Salesforce.
Financial details of the acquisition were not disclosed. The Information earlier reported on Anthropic’s bid to acquire Bun.
The deal comes as Anthropic pursues a more disciplined growth path than rival OpenAI, focusing on enterprise customers and coding workloads. Internal financials reported by The Wall Street Journal show Anthropic expects to break even by 2028—two years earlier than OpenAI, which continues to invest heavily in infrastructure as it expands into video, hardware, and consumer products.
It also marks an increased push into developer tooling. Anthropic has recently seen backing from some of tech’s biggest titans. Microsoft and Nvidia pledged up to $15 billion in fresh investment in Anthropic last month, alongside a $30 billion commitment from Anthropic to run Claude Code on Microsoft’s cloud. This is in addition to the $8 billion invested from Amazon and $3 billion from Google.
Anthropic’s spokesperson did not respond to requests for comment.
