Walmart lets AI agents buy on shoppers' behalf while Amazon blocks them

As Amazon blocks AI agents from shopping on its site, Walmart is doing the opposite: it introduced technology that lets AI agents make purchases for customers, with controls over spending and transaction approvals.

Why it matters: agent-accessible storefronts are becoming a split decision for retailers, which directly shapes how brands get surfaced in agentic shopping and AI search (KwikGEO) and mirrors Shopify's Shop MCP / Checkout MCP push.
