Amazon’s Secret Price-Fixing Playbook Exposed: What California’s New Evidence Reveals
The One-Penny Difference That Got a Seller Banned: Inside Amazon’s Alleged Price-Fixing Scheme
A toddler pajama set. A single penny. And a billion-dollar secret.
That's what it took for Mayer Handler, a small clothing company owner, to learn exactly how Amazon allegedly keeps prices high across the entire internet.
Handler's company, Leveret, was selling a tiger-themed pajama set for $19.99 on Amazon. On Walmart, the exact same pajamas were $19.98. One penny cheaper. Harmless, right?
Within days, Amazon sent Handler an email with bad news: his product was "no longer eligible to be a featured offer." The Buy Box, that golden "Add to Cart" button that drives the vast majority of sales, had vanished. The reason? That single cent on Walmart.
Handler's story is just one thread in a massive tapestry of evidence that California's attorney general, Rob Bonta, has been weaving together since 2022. And last week, hundreds of previously redacted documents were finally unsealed, giving the public its clearest look yet at what Bonta calls Amazon's "large-scale price-fixing" operation.
The documents include internal emails, confidential corporate presentations, and sworn deposition testimony, all filed in San Francisco Superior Court but never before made public. And they paint a picture of an e-commerce giant so obsessed with appearing to have the lowest prices that, paradoxically, it may have made everything more expensive for all of us.
What Just Happened? The Unsealing Everyone's Talking About
In September 2022, California sued Amazon under the state's Unfair Competition Law and Cartwright Act, accusing the company of anticompetitive pricing practices that stifle competition and raise prices across the board.
For three-plus years, huge portions of the evidence have been hidden behind thick black redaction bars. Amazon fought to keep it that way. But on April 16, 2026, a significant chunk of those redactions came off, and The Guardian obtained and reviewed the full cache.
The timing matters. Just this week, a San Francisco judge denied Amazon's motion for summary judgment, ruling that there are "too many disputed material facts" about whether Amazon's policies promote competition or crush it.Translation: this case is going to trial.
That trial is set for January 19, 2027. Before that, on July 23, 2026, the court will hear arguments on California's request for a preliminary injunction, which would force Amazon to change its practices immediately, even before a final verdict.
So what exactly is in these newly unsealed records?
How Amazon Allegedly Keeps Prices High (Without You Noticing)
The Buy Box Trap
If you've ever bought anything on Amazon, you've used the Buy Box. It's that panel on the right side of every product page with the "Add to Cart" and "Buy Now" buttons. It's the default path to purchase. And if you're a seller, losing access to it is basically a death sentence for that product's sales.
Here's the alleged scheme, according to California prosecutors:
Amazon uses automated tools to constantly monitor what independent sellers are charging for the same products on competing sites, Walmart, Target, eBay, even the sellers' own websites. If Amazon's algorithm detects a price anywhere else that's lower than what's listed on Amazon, it triggers consequences.
Sometimes the seller loses the Buy Box. Sometimes the product gets "suppressed", essentially hidden from search results and recommendations. Sometimes both.
And the threshold for triggering these penalties? It can be absurdly small.
Handler's deposition, which had been marked "highly confidential," reveals that his company received an email from Amazon in October 2022 stating that his pajama set was no longer eligible for the Buy Box because "the price on Amazon was higher than the price was on Walmart." When asked how much higher, Handler answered: "One penny."
His company scrambled. They either "changed pricing on Walmart to match or exceed Amazon's price" or "changed the code", altering the product's identifier to try to evade Amazon's tracking system.
"If You Discount Elsewhere, We'll Hide You"
Handler isn't alone. Another seller, whose name remains redacted, testified that a product suppressed by Amazon was magically reinstated to the Buy Box after they raised their price on Wayfair.
Perhaps most revealing: an Amazon engineer admitted in testimony that the company uses Buy Box suppression specifically to discourage sellers from using Temu, the Chinese discount platform that's been eating into Amazon's market share.
The documents also show that Amazon didn't just punish sellers who were caught. The company allegedly instructed vendors to raise prices on competing platforms and explicitly warned of "commercial consequences" if they failed to comply.
California argues this amounts to a coordinated price floor, a de facto agreement that keeps prices from ever falling below Amazon's level, no matter how much cheaper a competitor might be willing to sell.
Project Nessie: The Secret Algorithm
While the California case focuses on how Amazon allegedly pressures sellers, a parallel lawsuit from the Federal Trade Commission (FTC) reveals another layer: Amazon allegedly used its own secret algorithm to actively raise prices across the entire market.
The FTC's partially unredacted complaint describes an internal tool codenamed "Project Nessie", a pricing algorithm that predicted which products competitors would price-match. Amazon would then raise its price on those items, wait for Walmart or Target to follow suit, and then maintain the higher price once the competition had adjusted.
According to the FTC, this single algorithm extracted more than $1 billion in excess profits from American households.
Amazon's spokesperson Tim Doyle says the FTC "grossly mischaracterizes" the tool, claiming Nessie was meant to prevent prices from dropping so low they became "unsustainable." The company says it stopped using the algorithm years ago.
But the FTC's complaint includes a January 2022 email from a senior Amazon retail executive asking about using "old friend Nessie, perhaps with some new targeting logic", suggesting the tool, or something like it, remained on the table long after Amazon claims it was scrapped.
What Amazon Says in Response
Amazon's defense is, in essence: We're just trying to give customers the best deal.
In a statement provided to The Guardian, Amazon called the lawsuit's claims "entirely false and misguided." The company pointed to its reputation as "America's lowest-priced online retailer" and argued that "it is ironic that the attorney general seeks to have us feature higher prices in ways that would harm consumers and competition."
The company also offered this analogy: "Just like any store owner who wouldn't want to promote a bad deal to their customers, we don't highlight or promote offers that are not competitively priced. It's part of our commitment to featuring low prices to earn and maintain customer trust."
But here's where Amazon's framing gets tricky.
The company isn't just refusing to "promote" higher-priced items, the evidence suggests it's actively hiding sellers who offer lower prices elsewhere. And those sellers, facing the existential threat of losing Amazon's massive customer base, have little choice but to raise their prices on Walmart, Target, and their own websites to match whatever Amazon charges.
This week's court ruling suggests the judge isn't buying Amazon's framing either. The court found that Amazon "didn't definitively show it hadn't entered into prohibited price agreements with sellers in return for making it easier for customers to find and buy their goods."
The case moves forward.
What This Means for You (Yes, Your Actual Wallet)
I know what you might be thinking: This sounds like a fight between giant corporations and government lawyers. Why should I care?
Here's why.
California Attorney General Rob Bonta has repeatedly tied this case to the ongoing affordability crisis. "Especially while consumers face an affordability crisis, there is no room for illegal practices that impede competition and raise prices," Bonta said when the records were unsealed.
The mechanics are straightforward. If Amazon effectively forces sellers to maintain the same (or higher) prices on Walmart and Target that they charge on Amazon, then competition breaks down. Walmart can't undercut Amazon. Target can't run a better sale. The "race to the bottom" on prices, the very thing that's supposed to make capitalism work for consumers, gets turned into a coordinated floor.
And here's the kicker: Amazon charges sellers significant fees, reportedly averaging around 39.5% for those using its fulfillment services.Those fees get baked into the price you pay. If sellers can't offer discounts elsewhere to compensate for those fees, the higher price becomes the universal price. Everyone loses except Amazon.
The state's lawsuit argues that these practices "stifle price competition among online retailers, causing higher prices for consumers on and off Amazon."Not just on Amazon, everywhere.
What Happens Next? The Road to January 2027
The legal calendar is now set:
- July 23, 2026: Hearing on California's motion for a preliminary injunction. If granted, Amazon would be forced to stop its alleged practices immediately, and a court-appointed monitor would oversee compliance.
- January 19, 2027: Trial begins in San Francisco Superior Court.
But this California case is just one front in a broader war. The FTC's lawsuit against Amazon is grinding through federal court in Washington state, with recent rulings requiring the agency to specify exactly what remedies it plans to seek.The UK is pursuing its own multibillion-pound class action against Amazon over similar price-inflation claims.And Italy's antitrust authority has already levied fines totaling hundreds of millions of dollars, fines Amazon continues to appeal.
Whatever the outcome, the case is likely to reshape how e-commerce pricing works. A ruling against Amazon could force the company to stop penalizing sellers for offering lower prices elsewhere, which could unleash genuine price competition across the internet. A ruling for Amazon could cement the status quo.
How to Be a Smarter Shopper Right Now
While the lawyers duke it out, you don't have to be a passive participant. Here's what you can do today to protect your wallet:
1. Compare prices across at least three sites before buying. Don't assume Amazon has the best deal just because it's Amazon. Check Walmart, Target, eBay, and, crucially, the seller's own website. Sometimes you'll find the exact same product for less.
2. Use price history tools. Browser extensions like CamelCamelCamel and Keepa show you the historical pricing of any Amazon product. You'll see whether that "deal" is actually a deal or just a return to normal after an artificial spike.
3. Check the seller's website directly. Many independent sellers have their own online stores. Because they avoid Amazon's fees, they can often offer lower prices, if they're not being penalized for doing so.
4. Follow the case. The preliminary injunction hearing in July could bring immediate changes. We'll be covering it here.
A single penny on a toddler's pajama set might sound trivial. But multiply that penny across millions of products and hundreds of millions of shoppers, and you start to see the scale of what's at stake. California's lawsuit alleges that Amazon built a system designed to make sure you never find a better price anywhere else, not because Amazon's price is the best, but because it's the only one sellers are allowed to offer.
Whether that's illegal is now for a California jury to decide.
In the meantime, the smartest thing you can do is shop like a detective. Because in the world these newly unsealed documents describe, the price you see isn't necessarily the price that competition would have given you.
It's the price Amazon wanted you to see.
