Amazon Bars Meta’s Muse AI From Shopping on Its Site
Amazon has cut Meta’s twelve-day-old Muse agent off from shopping on Amazon.com, serving users a popup that cites its Conditions of Use rather than accusing anyone of hacking. That wording is deliberate: on 4 August 2026 the Ninth Circuit ruled in the Perplexity Comet case that the user, not the AI company, is the party accessing a retailer’s computers, and denied rehearing on 10 September. This article covers Amazon’s stated objections, how Muse actually reaches a site with no agent API, the litigation timeline, the $68 billion advertising business at stake, and how Amazon’s own Buy for Me feature differs.
