Judge grants Perplexity temporary permission to access Amazon’s site with ‘agentic AI’
The 9th U.S. Circuit Court of Appeals on March 16 temporarily reversed a lower court injunction, giving Perplexity's Comet browser continued access to Amazon's marketplace data via agentic AI — meaning AI that can autonomously browse, compare, and act on behalf of shoppers. This is not a minor legal footnote: Perplexity's agentic commerce layer can surface Amazon listings, compare prices across platforms, and execute purchases without the shopper ever touching Amazon's native search or sponsored placements. For sellers running $1M–$50M in Amazon revenue, this represents a structural threat to the advertising funnel — if Perplexity's agent is the new discovery layer, your AMS spend may be buying visibility that gets bypassed entirely. The appeal is ongoing, but the temporary window keeps Perplexity operational during what could be a 60–120 day appellate timeline.
The non-obvious play here is advertising cost trajectory: if agentic AI browsers become mainstream discovery tools, Amazon's sponsored placement monopoly weakens — but not because CPCs drop, because conversion rates on those clicks will decline as fewer high-intent shoppers ever reach Amazon's SERP.
Sellers optimizing purely for ACoS inside Amazon's walled garden are building on a foundation that a third-party AI layer can route around.
The $10M/year seller should immediately audit what percentage of their traffic is coming from AI-referral sources in Google Search Console and their Shopify analytics — if Perplexity or ChatGPT are already sending traffic, that channel is growing fast.
The strategic hedge is ensuring your product content, structured data, and brand presence are optimized for AI-agent legibility across all platforms, not just Amazon A+ content.
This case is the opening shot in a platform sovereignty war: Amazon built its moat around controlling the search-to-purchase loop, and agentic AI browsers are the first technology capable of breaking that loop at scale without the shopper noticing.
It fits squarely into the 2026 theme of AI-driven disintermediation — the same dynamic threatening Google's search ad revenue is now arriving at Amazon's sponsored products business. Operators who treat this as a legal curiosity will be blindsided when Q4 2026 conversion data shows a structural shift in how their best customers discover and compare products.
Audit your Brand Analytics 'Search Catalog Performance' report this week and flag any ASINs where click-through rate is declining despite stable impressions — this is an early signal that discovery is shifting off-platform before your ACoS metrics show the damage.
On Shopify and your DTC site, go into Google Search Console > Search Results > filter by 'Site' and look for referral traffic from perplexity.ai and chatgpt.com today — if either is already in your top 20 referrers, reallocate 10–15% of your content budget to structured data and FAQ schema optimization immediately.
In the next 30–60 days, prepare for Amazon to tighten its Terms of Service around third-party data scraping and potentially introduce new 'Buy with Prime' API partnerships with AI platforms as a defensive moat — position your catalog now to be eligible for Buy with Prime so you're inside Amazon's approved agentic commerce layer, not locked out of it.
Bottom Line
Perplexity's AI agent can now window-shop your Amazon listings for consumers — and your ad spend didn't buy that shelf.

Full Coverage
A legal battle between the artificial intelligence (AI)-powered discovery platform Perplexity and Amazon spilled over to a U. S. appeals court following a judge’s order on March 9. U. S. District Judge Maxin Chesney ordered that Perplexity should not be allowed to access password-protected information on Amazon’s site.
That order came in response to Amazon’s request for a preliminary injunction, halting activity taking place through Perplexity Comet web browser. However, the 9th U. S. Circuit Court of Appeals halted that order on March 16. It gave Perplexity a temporary window to continue operating as it had been previously.
Meanwhile, Perplexity continues to appeal the district court’s decision from March 9. News Perplexity's agentic commerce experience to expand to free users Brian Warmoth | Nov 19, 2025
