Financial Giants and Regulators Establish AI Agent Commerce Frameworks

Financial institutions and regulatory bodies are establishing liability and identity frameworks to enable agentic commerce, where AI agents execute purchases on behalf of consumers. To close the liability gap that currently deters consumers from allowing AI to complete checkouts, industry leaders are developing standards for verifiable identity and tamper-resistant proof of intent.

American Express announced in April 2026 that it would back purchases made by AI agents, provided the agent is registered on its network, the card member is authenticated, and authenticated purchase intent is transmitted. Other payment networks have introduced similar measures, including Visa's Trusted Agent Protocol and Mastercard's Agent Pay.

Competing technical standards have emerged to govern these transactions. Google, Shopify, Etsy, Wayfair, Target, and Walmart introduced the Universal Commerce Protocol in January 2026, while OpenAI and Stripe launched the rival Agentic Commerce Protocol.

Regulatory bodies are also clarifying the legal landscape. The U.K.'s Competition and Markets Authority declared that existing consumer laws apply to AI agent transactions, ruling that businesses remain responsible for compliance regardless of who built the agent.
