You thought you were comparison shopping. You opened two tabs. Amazon in one, Walmart in the other. Target sometimes. Home Depot for the drill. Chewy for the dog. You watched the prices, you picked the winner, you clicked. The internet, you were told, was a great leveler — a place where every retailer competed for your attention on the only axis that mattered. Price.
It wasn't. It was a set.
Behind the prices you compared, a coordination machine was running. Amazon's category managers watched Walmart, Target, Best Buy, Home Depot, and Chewy in real time. The second a competitor listed a product cheaper than Amazon, a category manager sent an email to the brand. The emails had subject lines like styles of concern.
The emails are now public.
The Email
In one now-unsealed exchange, an Amazon category manager wrote to Levi's with links to two Walmart listings flagged under the subject line styles of concern. Easy Khaki Classic Fit, on sale at Walmart. Too cheap.
Read that again. Levi's — not Walmart, not Amazon — called Walmart and told them to raise the price of a pair of khakis. Because Amazon told Levi's to make the call. Walmart complied. Amazon then matched the higher number.
Both retailers ended up charging more. The customer — you — paid the difference. Nobody competed.
The Mechanism
The playbook is simple enough to diagram on a napkin. It did not require a cartel in a smoky room. It required leverage, a mailbox, and a subject line.
- Amazon's crawlers spot a cheaper price on a competitor's site.
- A category manager emails the brand a link and a polite question about their "strategy."
- If the brand doesn't fix it, Amazon suppresses the listing — removes the Buy Box, buries it in search, makes it invisible to 300M customers.
- The brand calls Walmart / Target / Home Depot / Chewy. "Raise your price or we lose Amazon."
- The other retailer complies. They need the brand's inventory.
- Amazon un-suppresses. Every retailer's price is now higher — together.
The customer, throughout the whole loop, is watching two tabs — convinced they're witnessing a market.
The Leverage
Amazon captures roughly forty cents of every dollar spent online in America. That is not a platform. That is a chokepoint. When one company sits on 40% of the channel through which every major consumer brand reaches every online buyer, asking becomes indistinguishable from telling. The brand doesn't need to be threatened. The threat is the architecture.
Every styles of concern email carried the same silent footer: fix this, or your product disappears. Brands can't survive that. They made the calls.
Walmart, Target, Home Depot, Chewy — they took the calls and raised the prices, because they needed the brand's inventory more than the brand needed any one of them. The entire retail internet quietly synchronized its floor. Not through a meeting. Through a thousand polite emails about styles of concern.
The Algorithm
Alongside the emails, a second machine was running. Amazon called it Project Nessie.
Nessie raised the price on an Amazon listing and waited. If competitors matched the new, higher number, the price held. If nobody followed, Nessie quietly reset and moved on. Repeat, at scale, on millions of products.
The FTC alleges Nessie pulled more than a billion dollars out of American households before Amazon paused it. The filing is careful to note the algorithm was never deleted. Amazon can turn it back on today.
The emails coordinated what humans could reach. Nessie coordinated the rest.
The Backdrop
This is happening during the worst affordability crunch in a generation. Groceries up roughly 25% since 2020. Housing out of reach for most first-time buyers. Wages flat in real terms. The American consumer has been told, for a decade, that at least the internet is a place where you can find a cheaper price if you're willing to look.
For years, you weren't. You were looking at a coordinated price floor — set through backroom phone calls between companies you thought were competing for you.
