According to Business Insider, Amazon sent a legal threat this week to Perplexity, an $18 billion AI startup, demanding it block users from shopping with their AI assistant Comet on Amazon’s platform. Perplexity published a blog post on Tuesday titled “Bullying is Not Innovation” calling Amazon’s move “aggressive” and claiming it’s the retail giant’s first legal salvo against an AI company. Amazon responded with its own statement, arguing that third-party applications making purchases for customers should “respect service provider decisions whether or not to participate.” The company compared the situation to food delivery apps and online travel agencies needing restaurant and airline cooperation. Perplexity CEO Aravind Srinivas leads one of the highest-valued AI startups emerging during the current AI boom.
The Real Battle Over AI Shopping
Here’s the thing: this isn’t really about customer experience. It’s about control. Amazon built an empire on being the everything store, and now AI assistants like Comet threaten to become the everything shopper. Basically, Amazon doesn’t want to become just another supplier in someone else’s shopping interface.
Think about it. When you use an AI shopping assistant, you’re not seeing Amazon’s carefully curated sponsored results, upsells, or “customers who bought this also bought” recommendations. You’re getting what you asked for, plain and simple. And that terrifies Amazon’s advertising business, which generated $47 billion last year.
A Dangerous Precedent
Amazon’s comparison to food delivery apps is clever but flawed. Doordash needs restaurant menus and pricing, but they’re not fundamentally changing how people decide what to eat. AI shopping assistants could completely reshape how we discover and purchase products.
So what happens if every major retailer follows Amazon’s lead? We could end up with walled gardens where your AI assistant works perfectly on some sites but gets blocked from others. That defeats the whole purpose of having an AI that shops across the entire internet for you.
Where This Is Headed
This legal threat feels like the opening shot in what’s going to be a long war over AI agent sovereignty. We’re heading toward a future where your AI does your shopping, booking, and browsing—but only if companies like Amazon allow it.
Perplexity’s strongly worded blog post suggests they’re ready to fight this publicly. And honestly, they might have a point. Should any company be able to block how you choose to interact with their website? That feels like the digital equivalent of a store banning people who bring personal shoppers.
The outcome of this fight could determine whether AI assistants become truly useful agents that work across the entire web, or just glorified browser extensions that major platforms can disable whenever they feel threatened. And given how much money is at stake, I doubt this will be the last we hear about AI shopping wars.
