Quick Answer
AI liability in 2026 spans contract, tort, product liability, and professional negligence. The revised EU Product Liability Directive (Directive (EU) 2024/2853) now explicitly covers software and AI, while the AI Liability Directive proposal was withdrawn from the Commission's 2025 work programme — leaving national tort law to fill the gap.
- Developers, deployers, and users can all face liability
- Product liability now covers software and AI under EU PLD 2024
- Professional users (doctors, lawyers, engineers) remain accountable for AI-assisted decisions
What Is AI Liability?
AI liability concerns who pays when AI causes harm. Harm types include bodily injury, property damage, pure economic loss, discrimination, privacy violation, and intellectual-property infringement. Causation is often contested because AI outputs are probabilistic and value chains are long (foundation model provider to integrator to deployer to user).

Compliance Checklist
- Map each AI value chain: who trains, who deploys, who uses
- Draft AI-specific contracts with indemnity, warranty, and limitation of liability clauses
- Maintain incident response for bodily, property, financial, and digital harms
- For professionals (medical, legal): document human review of AI output
- Carry AI-specific insurance (e.g., Munich Re AI policies, Coalition cyber+AI endorsements)
- Comply with statutory duties (GDPR, HIPAA, Title VII, EU AI Act)
Conclusion
There is no single defendant for AI harm — there is a chain. Well-drafted contracts, documented oversight, and insurance close the gap.
