Ant International, Visa and Mastercard plan new AI-agent payment standard
↗
Ant International has signed on with Visa and Mastercard to develop a new standard for payments made through AI agents, referencing a McKinsey forecast of $3 trillion to $5 trillion in AI-driven commerce by 2030.
A unified protocol will dictate how AI agents authenticate, transmit, and store payment data, directly affecting the security architecture that engineers must build. The projected commerce volume means any vulnerability could be exploited at massive scale, so early alignment on security controls is critical. Collaboration among the three major networks could create industry-wide security baselines that downstream services will have to follow.

Ant International announced a partnership with Visa and Mastercard to create a unified payment protocol for AI agents.
The initiative cites McKinsey’s projection that AI-driven commerce could reach $3 trillion to $5 trillion by 2030.
The new standard is intended to address security and interoperability as AI agents handle increasing transaction volumes.
THE READ
What the cluster adds up to.
Ant International, Visa and Mastercard have agreed to work together on a new standard that will govern payments initiated by AI agents. The announcement frames the effort as a plan rather than a finished specification, indicating that the technical details are still under development. By joining forces, the three firms aim to shape how AI-mediated transactions are processed across their networks.
For engineers, adopting the forthcoming standard will likely require changes to existing payment APIs, integration of new authentication flows, and compliance testing against the protocol’s security requirements. Because the standard is being defined by the payment networks, developers may need to undergo certification or validation steps before their AI agents can transact. These steps represent additional development and operational overhead compared with current legacy payment integrations.
The standard will only apply to transactions that are initiated or mediated by AI agents; traditional human-driven payment flows will continue to use existing protocols. Until the specification is published and supported by the networks, AI-based services will remain unable to leverage the new framework, limiting its immediate impact. Consequently, any security guarantees promised by the standard are contingent on its final adoption and enforcement.
Security is a central concern because the plan references a McKinsey projection of $3 trillion to $5 trillion in AI-driven commerce by 2030, suggesting a massive increase in transaction volume handled by autonomous agents. A breach in an AI-agent payment flow could expose large amounts of financial data, making robust encryption, authentication, and fraud-detection mechanisms essential. Engineers will need to design their systems to meet the forthcoming security baselines to protect both users and the broader payment ecosystem.
