→Why spend hundreds of millions acquiring open-source AI infra?
Anthropic acquired Bun, Vercept, Coefficient Bio, and Stainless within six months, while OpenAI acquired Astral; the post does not disclose deal values, terms, or the cost comparison against forking the open-source projects.

editor take
Anthropic buying Bun and Stainless is not open-source confusion; it is moving Claude Code’s load-bearing walls in-house. Forks don’t buy roadmap control.
sharp
Anthropic’s acquisitions look less like tool shopping and more like removing shared infrastructure from neutral ground. Bun is MIT-licensed, has 7 million monthly downloads, and sits under Claude Code’s native installer. Stainless generated SDKs for OpenAI, Google, and Cloudflare; Anthropic paid more than $300 million to own that layer. Open source gives you copying rights, not the original team, release cadence, or denial value.
I don’t buy the naive “just fork it” take. Bun merged over 1 million lines of Rust in four days after a rewrite driven by the original team and Anthropic’s agents. That is not community maintenance. OpenAI buying Astral follows the same math: uv has 126 million monthly downloads, but the asset is Charlie Marsh’s team and Python workflow control. The labs are buying valves in the developer pipeline.
