Funding Round: Series C (Anthropic)

Verdictcontradicted95%
1 check · 4/13/2026

The source confirms the Series C round raised $450 million in May 2023, which matches the record's 'raised' and 'date' fields exactly. However, the source text is dated April 2026 and discusses multiple subsequent funding rounds (Series D in February 2024, Series E in March 2025). The record appears to be outdated as it only captures the Series C information without acknowledging that Anthropic has completed additional funding rounds since then. More critically, the record's 'name' field lists 'Series C (Anthropic)' which is correct, but in the context of the source's comprehensive funding history, presenting only Series C as current is misleading. The specific data points for Series C are accurate, but the record is incomplete relative to the source's current knowledge state.
