Visa has announced an investment in Replit and the launch of Visa Intelligent Commerce — an initiative to build payment infrastructure for AI agents. This is one of the first cases where a global payment network operator publicly declares readiness to process transactions initiated not by humans, but by autonomous software.
Trusted Agent Protocol — a new authorization standard
The centerpiece of the announcement is the Trusted Agent Protocol (TAP) — a specification developed by Visa that defines how an AI agent can obtain authorization to conduct a transaction on behalf of a user. TAP introduces three key mechanisms: payment tokens assigned to a specific agent, granular spending limits set by the user, and a full audit trail of every operation.
According to Visa documentation, TAP is designed to work on top of existing card infrastructure — agents will execute payments through standard network APIs without the need for separate settlement rails. This means merchants don't need to change anything on their end, with all authorization and limit logic handled by the token issuer.
Replit as the environment for building payment agents
The investment in Replit fits directly into this strategy. The platform — valued at $9 billion in a Series D round in March 2026 (up from $3 billion in September 2025) — enables building, running, and deploying applications powered by AI agents without managing one's own infrastructure. Visa notes that over 1,000 of its employees already use Replit to build internal tools.
Replit reports a Net Dollar Retention (NDR) rate of 300% in some enterprise segments, meaning existing enterprise customers triple their spending year-over-year. The platform offers a self-serve enterprise tier with annual fees reaching $200,000. These figures suggest growing demand for tools enabling rapid prototyping of agentic applications in business environments.
Market context: payments are becoming an AI agent domain
Visa's move is not isolated. Google is testing agents for online shopping through Project Mariner, Mastercard has announced its own Agent Pay program, and Stripe is expanding its API with endpoints optimized for programmatic access. The common thread across these initiatives is the assumption that a significant portion of e-commerce transactions will, within a few years, be initiated by autonomously operating software.
For Visa, the key is to occupy an infrastructure position before competing standards take shape. TAP has the potential to become for agentic payments what 3D Secure became for online payments — a de facto protocol that every issuer and merchant will be required to support. The alternative is protocols built by LLM operators themselves, which could push traditional card networks out of the value chain.
Security and liability implications
The TAP architecture raises several questions that Visa has yet to answer precisely. Who bears responsibility for a transaction initiated by an agent that misinterpreted a user's instruction? How do chargeback mechanisms work in a scenario where the user claims the agent exceeded its granted permissions?
Visa has announced that full TAP technical documentation will be made available to partners in the third quarter of 2026. Until then, the Intelligent Commerce program operates in a closed beta with a limited number of selected technology partners and financial institutions.
Strategic assessment
The investment in Replit is a relatively modest financial move for Visa — the amount was not disclosed — but the strategic signal is clear: the company views the AI agent developer ecosystem as a key distribution channel for new payment products. Replit gives Visa direct access to thousands of developers building agentic applications, who when integrating payment modules will naturally reach for tools recommended by the platform.
TAP and Intelligent Commerce are infrastructure whose success depends on adoption — both from token issuers and agent developers. If Visa can build sufficient critical mass before competitors, it may define agentic payment standards for the next decade. If not, it risks the protocol becoming yet another standard that exists on paper but not in production.
