While Amazon blocks AI agents, Walmart rolls out the welcome mat

Walmart has rolled out new technology that allows AI agents to make purchases on behalf of customers, giving users control over spending limits and transaction approvals. This stands in sharp contrast to Amazon, which has been actively blocking AI agents from accessing its shopping platform.

The move highlights a growing divergence among major retailers on how to handle autonomous AI agents in e-commerce. Walmart's approach suggests the company sees agent-driven shopping as an opportunity to capture a new channel of demand, while Amazon's defensive posture reflects concerns about fraud, unauthorized transactions, or disruption to its existing ecosystem.

For the AI industry, this is a notable signal that agent-based commerce is moving from concept to real-world deployment. As large language models and agent frameworks become more capable, retailers will increasingly need to decide whether to build infrastructure that accommodates autonomous purchasing agents or resist the shift.

The spending controls and approval mechanisms Walmart has built in address a key concern around agent autonomy — ensuring that AI-driven transactions remain within user-defined boundaries. This kind of guardrail design may become a standard feature as more platforms open their doors to agent traffic.
