Thune/Cruz/Klobuchar draft frontier bill: duty of care and federal power to block unsafe releases
Includes state preemption on CBRN risks; stalled on who conducts testing; only a few Senate weeks before the November midterms.
After an incident, law stops frontier development in major jurisdictions; progress moves underground or abroad.
A visible incident (an agent breakout with casualties, a bio scare, an election) produces a legislative overreaction: moratoria, licensing that only incumbents can meet, or outright bans on classes of models. Development continues in less regulated jurisdictions and inside governments. The freeze buys time in the regulated world and loses visibility everywhere else.
Observable thresholds. When one crosses, the scenario's status changes and the weekly re-run is brought forward.
Every change is logged with its reason and the signals that drove it. Moves are bounded per week; a jump beyond the bound is flagged as a shock.
Disagree with our range? Set yours. Estimates feed a community view that appears once enough people weigh in, and the weekly run reads the gap between our number and yours.
Seed estimate. The Senate frontier bill includes release-blocking authority; Metaculus gives 24% for a kill-switch bill by September 2027. A freeze requires an incident plus political will; the EU has just moved the other way.
Includes state preemption on CBRN risks; stalled on who conducts testing; only a few Senate weeks before the November midterms.
