In one paragraph

Illinois's SB 3502 (104th General Assembly) would create the Artificial Intelligence Design Requirements Act, setting rules for product liability actions against AI developers for defective design, inadequate instructions or warnings, and breach of express warranty. A deployer would be treated as a developer if it makes a material and substantial change or intentionally misuses the product contrary to the express warranty. Re-referred to Senate Assignments May 22, 2026.

What it means for business

Not law. AI developers would face product liability claims, and deployers who materially change or misuse an AI product would be liable as developers, if the bill were enacted.

Key provisions

  1. Would set provisions for product liability actions against an AI system developer for defective design, failure to contain adequate instructions or warnings, and failure to conform to an express warranty
  2. A deployer would be liable as a developer if it makes a material and substantial change to the product; "deployer" would exclude individuals or businesses with fewer than 20 employees or less than 10,000 users of their product
  3. A deployer would also be liable as a developer if it intentionally misuses the product contrary to the express warranty and that use was the proximate cause of harm
  4. Would set provisions concerning applicability and enforcement
