I’ll be honest — after sitting through a string of SXSW talks filled with phrases like “change is coming” and “the future is now,” I was ready to tap out. The audience doesn’t need more inspiration. If people are paying thousands of dollars to be there, I have a feeling they’re already pretty inspired. What they’re looking for is clarity — what’s actually happening right now in web3 world.
Then one speaker finally said something real.
Matthew Prince from Cloudflare didn’t talk about the future. He talked about what’s already unfolding beneath the surface of the internet. And what he pointed to is something that, surprisingly, almost nobody is discussing: retailers are already choosing sides on whether AI agents are allowed to shop.
At first glance, that might sound like a minor technical issue. It’s not. It’s a fundamental shift in how commerce may operate. Because for the first time, we’re seeing the possibility that the interface — the website, the app, the storefront — may no longer be where decisions are made.
Instead of a human browsing a site, comparing products, and clicking “buy,” the flow is starting to look different. A person asks an AI agent for the best option, the agent searches across multiple sources, evaluates based on data, and eventually executes the purchase through an API. It’s a subtle change on the surface, but underneath, it completely rearranges who holds power in the transaction.
And this is where the split begins.
Walmart appears to be moving toward openness. The logic is straightforward: if agents are going to become the new way people shop, then Walmart wants to be accessible to them. It doesn’t need to own the interface as long as it captures the order. In that model, distribution matters more than control. If the customer starts their journey in an AI assistant instead of a website, that’s fine — as long as the transaction still flows through Walmart.
Amazon, on the other hand, is taking a very different approach. It is pushing back, restricting automated access, tightening policies, and signaling — both technically and legally — that it does not want third-party agents sitting between itself and the customer. That stance makes more sense when you understand what Amazon actually is. It’s not just a retailer. It’s a search engine.
A significant portion of Amazon’s business comes from the moment before you buy. Brands pay to appear in search results. Visibility is monetized. The interface itself — the rankings, the listings, the placement — is the product. If an AI agent replaces that interface, the entire model is at risk. An agent doesn’t scroll. It doesn’t see sponsored listings. It doesn’t care who paid to be at the top. It simply returns the best match based on its criteria.
Remove the search page, and you remove the ad layer. That’s not a feature change. That’s a business model problem.
Which is why this isn’t really a debate about APIs at all. It’s a fight over who owns the customer relationship in a world where software, not humans, increasingly makes decisions.
Right now, the industry is framing the question as whether AI agents should be allowed to shop. But that framing misses the point. The real question is who controls the agent. Is it the retailer, enforcing access through closed systems? Is it the AI platform, becoming the new interface layer? Is it an open protocol that allows agents to interact freely across services? Or is it the user, somehow retaining control over their own digital proxy?
There isn’t an answer yet. But what’s clear is that companies are already making their bets.
What makes this moment so interesting is that it’s happening quietly. While headlines are dominated by oil prices, geopolitical tension, and market volatility, a much deeper shift is taking place in the infrastructure of the internet. The rules that govern how software interacts with software — who is allowed in, who is kept out, and under what conditions — are being renegotiated in real time.
Most consumers won’t notice this immediately. Everything still looks the same. Websites still load. Apps still work. Orders still get delivered. But underneath, the entry point to commerce is beginning to move. And once that entry point shifts, everything downstream tends to follow.
For the last two decades, the companies that won in commerce were the ones that controlled the interface. They owned the search results, the user experience, the moment of decision. But if AI agents become that interface, then the advantage shifts to whoever controls access to the underlying systems.
That’s why this matters.
Because the next era of commerce may not be decided by who has the best website, or the best brand, or even the best product. It may be decided by something far less visible — something most people will never see directly.
It may be decided by who decides how machines are allowed to access them.
And that decision isn’t coming in the future.
It’s already being made.
