AI CEOs Sign Biosecurity Letter Urging Congress to Act

Sam Altman (OpenAI), Dario Amodei (Anthropic), and Demis Hassabis (Google DeepMind) have co-signed a letter to Congress urging increased oversight of synthetic nucleic acid orders and related equipment. The signatories cite AI models becoming increasingly bio-capable as the motivating threat — making the supply chain for DNA synthesis equipment a biosecurity priority, not just a chemical safety one.

Why It Matters

Three CEOs of the leading frontier AI labs jointly calling for regulation of their own downstream capabilities is a notable policy signal. It frames AI's biohazard risk as self-acknowledged by the labs producing it — before a regulatory mandate, not in response to one.
