A federal judge grants a temporary injunction against the Comet browser, highlighting the escalating battle over data scraping, cybersecurity, and the future of e-commerce.
- A federal judge granted Amazon a temporary injunction to stop Perplexity’s Comet AI browser from scraping its e-commerce platform without authorization.
- Amazon successfully argued that the concealed AI agents posed significant security risks to password-protected accounts and disrupted its multibillion-dollar advertising ecosystem.
- The legal battle underscores a broader industry trend of major tech platforms aggressively locking out third-party AI scrapers while promoting their own homegrown artificial intelligence tools.
The intersection of e-commerce and artificial intelligence just hit a major legal speed bump. In a decisive early victory for the retail behemoth, Amazon has won a temporary injunction against AI startup Perplexity, effectively blocking its Comet artificial intelligence browser from accessing and scraping Amazon’s website. Handed down by U.S. District Judge Maxine Chesney, the ruling marks a significant escalation in the ongoing battle over who controls the digital shopping experience in the age of AI.
The conflict officially began in November when Amazon filed a lawsuit in the U.S. District Court in the Northern District of California. Amazon’s core allegation was that Perplexity took deliberate steps to “conceal” its AI shopping agents, allowing them to stealthily scrape the online retailer’s vast catalog without approval. Perplexity’s Comet browser is designed to let shoppers ask an AI assistant to find items on Amazon and execute purchases on their behalf. However, in her Monday ruling, Judge Chesney declared that Amazon provided “strong evidence” that Comet was accessing the site at the user’s direction but entirely “without authorization” from the e-commerce giant.
This unauthorized access carried tangible costs for Amazon. During the proceedings, Amazon submitted what the judge described as “essentially undisputed evidence” that the company was forced to expend “numerous hours” and more than $5,000 specifically to develop countermeasures. These internal tools were necessary to block Comet from accessing private customer tools and to prevent future unauthorized entry. Given these facts, Judge Chesney concluded that Amazon showed a strong likelihood of succeeding on the merits of its claim.
Beyond the immediate scraping of product data, Amazon’s original complaint highlighted two massive systemic threats posed by Perplexity’s bots: customer security and advertising integrity. Amazon argued that because these AI agents can act within protected computer systems—including private, password-required customer accounts—they introduce severe security vulnerabilities.
Furthermore, rogue AI traffic wreaks havoc on Amazon’s highly lucrative advertising business. When bots generate ad traffic, those fake impressions must be meticulously detected and filtered out before advertisers are billed. As Amazon noted in its complaint, adapting their systems to identify automated traffic is crucial to maintaining contractual obligations with advertisers who expect to pay only for “legitimate human impressions.”
Following the court’s decision, Amazon spokesperson Maxine Tagay emphasized that the preliminary injunction is a vital step in maintaining “a trusted shopping experience” for consumers, adding that the company looks forward to continuing to make its case in court.
Perplexity has not backed down. The startup previously dismissed the lawsuit as a “bully tactic,” and in a recent statement to CNBC, vowed that it “will continue to fight for the right of internet users to choose whatever AI they want.” The judge has granted a weeklong stay on the ruling, giving Perplexity a brief window to appeal the order.
Taking a step back, this legal clash is emblematic of a broader tech industry trend: the rise of the AI walled garden. Amazon is not just targeting Perplexity; the retail giant has systematically locked down its shopping sites from dozens of third-party AI agents, including OpenAI’s immensely popular ChatGPT. By shutting the door on external AI tools, Amazon is simultaneously clearing the runway for its own proprietary innovations, such as Rufus, the homegrown shopping assistant now heavily featured across its website and app. As artificial intelligence continues to reshape how we navigate the internet, the fight between platforms guarding their data and startups trying to build upon it is only just beginning.
