Science writer Kevin Bass published a viral thread in September 2026 alleging that METR, a nonprofit conducting safety evaluations for major AI companies, receives funding traced through multiple foundation layers to Anthropic investor Dustin Moskovitz, raising questions about its independence. The claims rely on public IRS filings and SEC records but lack definitive proof of direct funding to METR itself, while METR disputes the allegations and the timing coincides with Anthropic's disclosure of a security incident and METR's launch of an independent investigation.
