Stripe's new positioning: KYA is not a payment layer, but an AI Agent infrastructure.

Stripe data shows that the real cost of every transaction in the AI economy far exceeds the payment link: one AI client intercepts 250,000 fraudulent trials per week with a conversion rate of only 4%, and abusive users cause the company to lose 625 times the cost. Stripe believes that the next generation of payments is not in the payment layer, but in KYA (Know Your Agent) infrastructure. Stripe no longer views itself as a payment company, but as an infrastructure provider for the AI economy. The article deconstructs Stripe's actions, such as the acquisition of Bridge, Privy, and the self-built Tempo blockchain, to argue a counterintuitive conclusion: the next generation of payments is not designed from the payment layer, but derived from Agent economy scenarios, with payments being merely a subsystem of KYA. This analysis provides a brand-new framework for understanding financial infrastructure in the AI era. Irene Du, author of the Stripe AI strategy deconstruction series on the Xin public account, provides an in-depth analysis; this is the 2.5th installment of the series. The origin of this series lies in the fact that on April 30, Stripe Sessions 2026 released 288 products, and I observed that Stripe is attempting to become the economic infrastructure for the AI Agent era. The first article, "Stripe is not a payment company," attempts to answer "Why Stripe"—its DNA determines that it can do this. The second article, "KYC is dead, the Agent economy is rewriting the underlying layer of financial regulation," explores the future Stripe is betting on—what the Agent economy actually looks like, and why traditional payment infrastructure will fail completely in its face. However, during the second article, I received a comment from a peer: "I completely agree with the first half. Whether it's AB 316 or the laws of any sovereign state, 'Agents' will not be recognized as legal entities in the short term—the ultimate defendant will always be a specific person. This is something Know Your Agent cannot change, and cannot be changed." "But for the second half—'the only change is payment and settlement efficiency'—I reserve my opinion. The problem with this sentence is not the conclusion, but the framework it presupposes: it views KYA as an upgrade to the existing payment system." This is what I believe is worth writing another article to discuss. Let's return to the muscle memory of a former payment practitioner: Payment models are scenario-driven, not designed from within the payment system. Every real revolution in payments—online banking, mobile wallets, QR code scanning—was not because someone made a better product at the payment layer, but because a new transaction scenario emerged that overturned the underlying assumptions of the original payment system. New payment models are "derived" from the infrastructure required by that scenario, not "optimized" out of it. I once worked on payment innovation at Ant Group. At a platform that was an absolute industry leader in creating "Quick Payment," "Mobile Payment," and "QR Code Payment," the greatest joy and pain was thinking: what is the next generation of payment models? We did watch payments (as well as heartbeat authentication to replace facial recognition), NFC payments (the original technology for "tap-to-pay"), participated in and wrote many "next-generation" payment protocols, and even tried to get my boss to support me in exploring metaverse payments. Most of these projects didn't take off. Looking back, the reason is the same: we tried to define new payments at the payment layer, but the scenarios driving payment innovation hadn't arrived yet—without the scenario, the infrastructure required by the scenario could not be derived, and no matter how clever your design at the payment layer was, it couldn't catch it. The Agent economy is the new scenario I was waiting for. KYA is the infrastructure layer that is currently being derived. KYA is not a product of the payment layer; it is the infrastructure layer of the Agent economy. The five layers of KYA I defined in the previous article—Agent identity, authorization scope, intent signing, liability chain auditing, and credit rating—only two layers, authorization scope and liability chain auditing, fall on the payment link; the other three (identity, intent, credit) are not in payments at all. - The identity layer serves all scenarios that need to identify Agents: cross-platform calls, regulatory filings, internal corporate audits—payments are just one of them. - The intent layer serves the larger problem of AI alignment—payments are just one of its many verification scenarios. - The credit layer serves any system that needs to grant permissions and quotas to Agents—payments are also just one of the users. So, that peer's judgment that "the only change is payment and settlement efficiency," translated into
