Why Enterprise AI Fails at Scale
Key Takeaways
- A federal judge said Amazon has strong evidence that Perplexity crossed the line.
- Amazon says Perplexity hid its AI activity and worked around its defenses.
- Retailers may now tighten control over how outside AI agents access their sites.
Amazon secured a federal injunction blocking Perplexity's AI browser from its platform, escalating tensions over who controls how autonomous agents access ecommerce sites.
US District Judge Maxine Chesney ruled on March 10, 2026, that Amazon provided “strong evidence” Perplexity's Comet browser accessed its site “without authorization.” According to court filings, Amazon spent more than $5,000 responding to the issue, including employee hours developing tools to block Comet from accessing customer accounts.
“Given such evidence, the Court finds Amazon has shown a likelihood of success on the merits of its claim,” Chesney wrote. The ruling includes a weeklong stay for Perplexity to appeal.
Amazon’s suit against Perplexity was first filed in November 2025, alleging the startup concealed its AI agents to continue scraping the retailer's website. Perplexity called the lawsuit a “bully tactic” designed to stop companies from “making life better for people.”

Amazon vs Perplexity: Key Claims in the Dispute
What looks like a straightforward court fight is really a broader struggle over who owns the shopping journey in an AI-mediated market.
The main arguments include:
| Claim | What Each Side Argues |
|---|---|
| Security risks | Amazon alleges agents access protected customer accounts |
| Ad system impact | Automated traffic requires new detection mechanisms |
| Transparency | Amazon asserts Perplexity disguised AI agent activity |
| Consumer choice | Perplexity claims users deserve AI tool freedom |
| Shopping experience | Amazon argues agents degrade personalization |
Amazon, in its cease and desist letter to Perplexity, claims it “shares the industry’s excitement about AI innovations” and sees potential for agentic AI to improve customer experiences. But to do that, it claims purchases made on behalf of customers must operate transparently.
“Perplexity has refused to operate transparently and has instead taken affirmative steps to conceal its agentic activities in the Amazon Store,” the letter claimed.
The ecommerce giant went on to claim that it is entitled to injunctive relief to “prevent ongoing irreparable harm to Amazon and its customers caused by Perplexity.”

Amazon’s Stand Against Agentic Commerce
Amazon has broadly blocked external AI agents from its shopping sites, including OpenAI's ChatGPT, while investing in its own Rufus shopping assistant.
In its complaint, Amazon stated Perplexity's agents “can act within protected computer systems, including private customer accounts requiring a password.”
According to the cease and desist, Amazon reached out to Perplexity’s chief business officer, Dmitry Shevelenko, asking for its AI agents to act with "transparency" in the Amazon Store. “Perplexity refused to do so,” the letter claims.
Following that conversation, Amazon implemented new security measures to restrict Comet’s access. But within 24 hours, according to Amazon, Perplexity released a new version of Comet to knowingly circumvent that security measure.
“Amazon should love this,” Perplexity countered. “Easier shopping means more transactions and happier customers. But Amazon doesn't care.”
Perplexity stated it will continue to “fight for the right of internet users to choose whatever AI they want.”
How Big of an Impact Has AI Made on Ecommerce?
Traffic driven to seller sites by generative AI surged 693% during the 2025 holiday season. During Cyber Week alone, chatbots and agents were responsible for driving $67 billion in global sales, influencing roughly 20% of all purchases.
Browner integrations through platforms like ChatGPT, Gemini and Perplexity enable AI agents to bypass traditional search entirely. In fact, research from Salesforce found that nearly 40% of consumers now rely on AI to find new products — and 71% want AI integrated into their shopping experiences.
But the autonomous nature of agentic commerce creates new challenges for organizations, including data privacy concerns, accountability gaps and bot detection complexity.

This injunction firmly moves the AI scraping fight from abstract complaints to an early courtroom win.
Platforms have long tried to deter bots through tools like robots.txt, but those measures don’t always stop scraping or user-invoked AI agents. This ruling suggests courts may be willing to back stronger claims around unauthorized access when companies believe outside agents are crossing the line.

This matter extends far beyond Amazon. Google’s lawsuit against SerpApi shows another major platform attempting to crack down on third parties that extract and repurpose data from search and shopping interfaces.
For agentic commerce, this most recent ruling could redraw the rules of access. AI-driven shopping traffic and sales are rising fast — but retailers may push that activity into gated APIs and licensed partnerships instead of allowing outside agents to move freely across their sites.
“This is Amazon’s first legal salvo against an AI company,” Perplexity said in its blog post, “and it is a threat to all internet users.”
