Amazon blocks Perplexity shopping bot in court

This is a warning shot for every team building browser agents: acting like a user is not the same as being welcome on the platform. Agentic commerce is moving from demo magic to permissioned infrastructure, and courts are starting to define that boundary.

• –CNBC says the injunction targets Perplexity's Comet AI browser, making this a direct hit on agent-driven shopping rather than a generic scraping dispute.
• –Perplexity has been pushing shopping hard since its Shop like a Pro and Buy with Pro rollout, so losing Amazon access weakens one of the biggest retail endpoints for its agent ambitions.
• –Amazon looks to be defending control over marketplace rules, authentication, and checkout economics as much as raw site access.
• –Developers building web agents should now treat bot disclosure, permissions, and terms-of-service compliance as core product design constraints.
• –Rival AI shopping and browser-agent teams will read this as a signal that major consumer platforms may force formal partnerships before allowing autonomous purchasing.
