AI lab chiefs ask Congress to mandate synthetic-DNA screening
Altman, Amodei, Hassabis and 60+ others back a law to screen and log nucleic-acid orders as AI tops PhD virologists on lab questions

Summary
On 4 June 2026, more than 60 AI and national-security figures, including Sam Altman, Dario Amodei, Demis Hassabis, Mustafa Suleyman, Alexandr Wang and protein-design pioneer David Baker, signed "An Open Letter in Support of Mandatory Nucleic Acid Synthesis Screening and Recordkeeping" (screendna.org). It asks Congress to require synthetic-DNA/RNA vendors to screen orders against dangerous sequence motifs and keep records so investigators can trace split, individually-benign orders. The trigger: frontier AI now outperforms PhD-level virologists on many technical lab questions, eroding the knowledge barrier. Two bills compete, H.R. 3029 (voluntary-leaning) and S. 3741, the Biosecurity Modernization and Innovation Act, which would mandate Commerce Department rules. IBBIS is advancing the underlying ISO standards.
By the numbers
- 60+, signatories (AI lab chiefs, scientists, security figures).
- 4 Jun 2026, letter published.
- ~20%, share of the global synthesis market outside voluntary screening frameworks.
- 36 of 38, synthesis providers that shipped 1918-flu fragments undetected in an FBI-overseen red-team.
- 2, competing bills (H.R. 3029 voluntary; S. 3741 mandatory).
Why it matters
This is the AI×biology intersection turning into law-shaped pressure: the same labs building biological design tools want the synthesis chokepoint regulated before their models lower the barrier further. A mandate would reshape a fragmented global DNA-supply market and set whether AI-generated sequences get caught at the order desk.
What to watch
- Movement on S. 3741 vs H.R. 3029 in committee.
- Whether screening rules cover AI-generated/novel sequences, not just known pathogens.
- Adoption of IBBIS/ISO TC 276 standards by major synthesis vendors.
