Amazon blocks AI shopping agents while Walmart opens up to them

Implications · machine-drafted, not owner judgment
This is a direct test of the owner-tracked view that vendors won't let AI agents act against their own commercial interest, applied here to a retailer's own platform: Amazon's blocking stance protects its margin and ad business from agent-mediated disintermediation, while Walmart is betting that being agent-friendly captures share from AI-mediated buyers Amazon is shutting out. Whichever posture wins more agent-shopping volume likely becomes the default other retailers copy.
