Walmart’s October 21 announcement gives us a more concrete picture of how businesses might serve customers who send personal agents to shop for them. The retailer is introducing Agent Profiles, purchasing controls and a Walmart Agent Gateway that connects outside agents to its shopping systems. Agent Profiles are due within a month, while the gateway begins as an invitation-only beta for companies and developers.

Our recent Agentic Commerce report distinguishes among brand agents, platform assistants and personal agents. Walmart’s announcement shows how those categories can work together, while raising questions about who controls the connection.

A brand agent can become useful to other agents

One recommendation in our report is that brands build agents other agents can call. A customer may prefer to start with a personal assistant that remembers her household and shops across retailers. The retailer still has knowledge and capabilities that assistant needs.

Walmart’s gateway page says outside agents connect through Sparky. That gives Walmart’s own agent a role in serving customers who bring an assistant of their own. Such a direct agent-to-agent connection could be more efficient than having personal agents navigate websites built for people. Walmart says the gateway can reduce unnecessary requests, latency and token consumption, giving retailers another reason to make their capabilities available to outside agents.

From a consumer’s perspective, imagine telling your personal agent, “Get me more milk from Walmart.”

First, you’d connect the agent to your Walmart account. Walmart says you’ll start in the agent’s app, sign into Walmart and authorize an Agent Profile with purchasing controls. The connection would establish a route for future requests and is a one-time set-up for the consumer.

Walmart hasn’t published the full technical design, but the likely pattern is familiar. The agent’s software presents a digital credential that Walmart can check against your authorization. Walmart can then determine which account it represents and what it’s permitted to do. You may still need to approve the purchase. For a request like replenishing milk, Walmart says it can help identify your usual products without exposing your broader shopping history.

Delegation needs recognition on both sides

Some of Walmart’s controls will sound familiar to personal agent users. Meta, for example, already describes safeguards that require approval before Muse completes purchases.

Walmart adds recognition and control on the merchant’s side. An Agent Profile links the agent to the customer’s account, distinguishes its purchases and lets the customer revoke access.

A personal agent provider like Meta or Instinct needs to enforce the customer’s instructions. But Walmart is showing that the merchant also needs a basis for accepting the resulting requests. An agent saying it has permission is a weaker foundation than an authorization the merchant can verify.

The value of that record becomes clearer when something goes wrong. Walmart says its normal returns process will apply even when an agent doesn’t act as intended. That gives customers a familiar route for seeking a remedy, although it isn’t a blanket guarantee against agent mistakes.

Explicit purchasing permissions could help establish what happened. Did the agent buy within an agreed spending limit? Did the customer approve the order? Or did the purchase exceed the authority granted? Clear authorization matters before checkout, and it can make a resulting dispute easier to untangle afterward.

This is the chain of trust we discuss in our Agentic Commerce report becoming part of the customer account. It also creates a coordination challenge. Customers won’t want to approve the same purchase repeatedly because their agent and the retailer maintain separate controls. The companies involved still need to explain how those approvals will work together.

Welcoming agents still leaves the retailer in control of admission

Walmart’s opening comes with conditions. The gateway is an invitation-only beta, and Walmart reserves the ability to suspend access.

Our report argues that access should depend on what an agent can prove about whom it represents and what it’s authorized to do. Walmart’s approach raises a practical question. Will any agent that meets published requirements eventually be able to connect, including ones consumers host and run themselves? Or will access depend on individual commercial relationships?

The announcement doesn’t settle that question. It does give other businesses something concrete to consider. Customers will increasingly arrive with software acting on their behalf. Businesses need a way to recognize that delegation, limit its scope and keep a record of what happened.

The implications extend beyond checkout. A personal agent that places an order may later return to track delivery, report a missing item or request a refund. Walmart hasn’t confirmed those gateway capabilities, but the account connection and authorization record could provide a foundation for them.

The next question is what authority carries forward. Permission to buy a product doesn’t necessarily include permission to accept store credit or agree to a replacement. As shopping becomes agentic, service will need equally clear rules for what an agent can resolve and when the customer must decide.
