Anthropic — SDK adoption to a $60B+ valuation
Anthropic's GitHub signal lives in SDK installs and tool-integration density, not star slope — and that signal still led the $60B+ valuation.

- Anthropic's GitHub signal is in SDK install + integration density, not stars
Anthropic is the case study for foundation-model companies whose GitHub signal is downstream of the model's adoption. Stars on the SDK don't move the needle — install velocity does.
Through 2024 the Anthropic Python SDK was added as a dependency in nearly every credible agent framework: LangChain, LlamaIndex, CrewAI, DSPy. That dependency-graph density is its own leading signal.
The $60B+ valuation announced in March 2025 was a follow-on data point on a curve that had been steepening for two years.
Signals that would have flagged this pre-raise
- SDK dependency adoption:Default in agent frameworks by 2024
- Install velocity:Sustained pip-installs through 2024
- Tool-call ecosystem:MCP + tool calling ship as first-class features

Frequently asked questions
Can a deal-flow signal product track foundation-model rounds?
Yes, but the signal type is different — dependency adoption and integration density, not star slope.
