Funding Round: Series D (Anthropic)

Verdictconfirmed95%
1 check · 4/7/2026

The source text explicitly confirms all three key fields of the record: (1) name 'Series D' is correct, (2) raised amount of $750 million matches exactly, and (3) date of February 2024 (2024-02) matches exactly. The source states: 'In February 2024, Menlo Ventures led a Series D round of $750 million.' However, the source does not provide a specific valuation figure for the Series D round itself ($18.4 billion claimed in the record). The source mentions that 'Amazon invested $4 billion (paid out in two parts), bringing the valuation to $18.1 billion in early 2024' before the Series D round, so the $18.4 billion valuation for Series D is plausible but not explicitly confirmed in the source text. Since the three explicitly stated fields (name, raised, date) are all confirmed, and the valuation is not contradicted (it's close to the $18.1B mentioned for early 2024), the overall verdict is confirmed.
