A US appeals court overturns a ruling that had temporarily barred Perplexity from using its agentic shopping tools on Amazon's platform
A U.S. appeals court on Tuesday overturned a ruling that had temporarily barred Perplexity from using its AI-powered agentic shopping tools on Amazon's (AMZN.O) platform.
Context & Ripple Effects
Amazon’s dispute with Perplexity began with a cease-and-desist demand and Amazon’s computer-fraud lawsuit over Comet making purchases for users. A preliminary order then stopped the tool and required destruction of Amazon data, before the appeals court put that block on hold in March.
The latest ruling removes the temporary restriction rather than ending the underlying conflict, making it a consequential test of who controls customer-facing AI agents on a marketplace.
First-order effects
- Perplexity can again use its agentic shopping tools on Amazon’s platform after the appeals court overturned the temporary bar.
- Amazon loses the immediate judicial restriction it had obtained against Perplexity’s shopping activity while its broader claims remain contested.
Second-order effects
- Amazon must rely more heavily on its own platform rules and litigation posture to limit or shape third-party shopping agents during the dispute.
- Other AI-agent providers gain a closely watched procedural signal that marketplace access can remain available while courts weigh platforms’ claims.
Third-order effects
- The case sharpens the emerging question of whether large marketplaces can act as gatekeepers for agents that transact on users’ behalf, rather than merely for conventional apps and sellers.
- If similar rulings persist, agentic commerce will be shaped increasingly by platform permissioning and court-defined limits on automated access.
The trend: Agentic commerce is moving toward a contest over whether platforms or user-directed AI agents set the terms of marketplace access.
