NoteQUA-650 retro-scan: The claim is about Anthropic's Series B funding round (April 2022, $580M), but the source's primary subject is Anthropic's Series E funding round (March 2025, $3.5B). While the source mentions Series B as historical context, it is primarily about the Series E round, making it a MISMATCH per QUA-648 guidelines.
