The AI LEAD Act (Aligning Incentives for Leadership, Excellence, and Advancement in Development Act, S. 2937) is a bipartisan federal bill that would establish a product liability framework for AI systems. It was introduced in the 119th Congress on September 29, 2025 by Sen. Dick Durbin (D-IL) and Sen. Josh Hawley (R-MO), and was referred to the Senate Judiciary Committee.
Status and timeline
The bill was introduced on September 29, 2025 and referred to the Senate Judiciary Committee. As of June 2026, the congressional record lists the September 29, 2025 committee referral as the latest action, with no hearing, markup, or floor activity recorded (Source: congress.gov). Its sponsors are Sen. Dick Durbin (D-IL) and Sen. Josh Hawley (R-MO). Durbin is the ranking Democrat on the Senate Judiciary Committee and Hawley chairs its subcommittee on crime and counterterrorism; FedScoop reported the bill as the pair's vehicle to "classify AI systems as products and establish federal legal" pathways for people harmed by those systems to sue (Source: fedscoop.com).
Scope and definitions
The bill defines AI "design" to include "unexpected skills or behaviors," placing responsibility for emergent capabilities on developers. It presumes that minors are unable to recognize AI risks, a provision the bill's findings tie to teen chatbot harm cases. The bill provides for retroactive application, reaching harms that occurred before enactment.
Key provisions
The bill establishes four theories of developer liability for AI systems:
- Negligent design — failure to exercise reasonable care.
- Failure to warn — inadequate instructions or warnings about foreseeable risks.
- Breach of warranty — the product did not conform to promises.
- Strict liability — the product was defective and unreasonably dangerous, regardless of the care the developer exercised.
The strict liability standard imposes responsibility regardless of the care exercised, which the bill applies as the broadest liability standard among proposed US AI legislation.
Obligations by actor
Deployers are liable only if they substantially modify or intentionally misuse the product. Developers cannot contractually waive liability. Foreign developers must register a US-based agent. Under floor preemption, states may enact stronger protections than the federal framework.
Approach relative to other measures
The bill takes a product liability approach to AI governance, creating financial incentives for safety through litigation risk rather than through disclosure or regulatory compliance. This is distinct from the transparency-first approach of SB 53 and the RAISE Act; the safe-harbor or conditional-immunity approach of Illinois SB 3444, which is its direct philosophical opposite; the antitrust approach in algorithmic pricing cases; and the export-controls approach of Export Controls (AI).
Strict liability for "unreasonably dangerous" AI would reach AI Autonomy Risk and Emergent Misalignment scenarios. The combination of floor preemption with stronger state protections is consistent with the techno-federalism dynamic of states leading AI regulation. The foreign-developer registration requirement addresses AI and Authoritarianism concerns about foreign AI products in the US market.
Contrast with Illinois SB 3444
Illinois SB 3444 (introduced February 2026 by Sen. Cunningham, D-IL) is a philosophical counterpoint to the AI LEAD Act. Where AI LEAD imposes strict liability on frontier developers for emergent and foreseeable harms, SB 3444 grants conditional immunity for "critical harms" (100 or more deaths, $1 billion or more in property damage, CBRN enablement, or autonomous crime) in exchange for publishing a safety protocol and a transparency report. Sen. Durbin (D-IL) co-sponsors AI LEAD federally while his state-senate colleague Cunningham sponsors SB 3444, producing opposing liability frameworks from the same-state delegation at different levels of government. OpenAI publicly supports SB 3444, a shift from its earlier posture toward liability-expanding bills.
Reactions
The Center for Countering Digital Hate (CCDH) supports the bill, framing it as putting "safety and accountability at the heart of AI" and holding AI companies liable for harms they cause (Source: counterhate.com). OpenAI's support for Illinois SB 3444's conditional-immunity approach (see above) positions the largest AI developer's public posture against the AI LEAD Act's strict-liability framework.
