One month ago, the sharpest technical team in artificial intelligence looked inside Decart, ran full due diligence, and walked away from a $6 billion deal. This week, Amazon is reportedly ready to pay $7 billion for the same company. The Amazon Decart acquisition talks, first reported by the Wall Street Journal on October 11, are the strangest kind of market signal: two elite buyers, one asset, and a billion-dollar disagreement pointing in opposite directions. So what does Jeff Bezos know that Anthropic does not?

Start with what is actually known. The Journal reports Amazon is in talks to acquire Decart for around $7 billion, citing people familiar with the matter, and adds the only sentence that matters right now: a deal could come together soon, “assuming talks don’t fall apart or another suitor doesn’t emerge.” This is not a done deal. It is a negotiation with a headline number.

What Decart actually sells

Decart was founded in 2023 by three Israeli engineers, brothers Dean and Orian Leitersdorf and Moshe Shalev. It makes two things. The flashy one is real-time AI video: models like Lucy and Oasis that generate and edit video live and simulate 3D worlds for training robots. The boring one is the valuable one: software that makes it easier for developers to switch between different AI chips.

That second product is the whole story. If your code runs the same on Nvidia, Google, and Amazon silicon, then chips become a commodity and Nvidia’s pricing power cracks. Decart has raised more than $400 million from Sequoia, Benchmark, and Radical Ventures, and was valued at nearly $4 billion in May. Amazon is not paying $7 billion for video filters. It is paying for the crowbar that pries developers off Nvidia.

The $6 billion no that matters more than the $7 billion yes

Here is the data point everyone is underweighting. Bloomberg reported on September 7 that Anthropic had considered paying about $6 billion for Decart, completed due diligence, and chose not to proceed. Both companies declined to comment. Nobody outside those rooms knows why Anthropic passed, and anyone who tells you they do is inventing it.

But think about what a completed diligence pass means. Anthropic runs some of the deepest technical diligence in the industry. Its team saw the code, the benchmarks, the customer contracts, and the roadmap. Then it said no at $6 billion. A month later Amazon is circling at $7 billion. Either Anthropic missed something, or Amazon is buying something Anthropic was never shopping for.

My money is on the second one.

Why the Amazon Decart acquisition is about chips, not video

The Journal adds the detail that explains everything: Amazon Web Services gave Decart early access to its Trainium3 chip in 2025 after meeting the company and coming away impressed by its founders. CTech separately reported that Amazon has since become one of Decart’s strategic customers. Read that again. The buyer was already the power user.

Now the logic clicks. Amazon has spent years building custom silicon to escape Nvidia’s margin tax, but custom chips are useless if developers will not port their code. Decart’s chip-switching software is the missing adapter: it makes Trainium a credible alternative instead of a science project. Amazon is not acquiring a video startup. It is acquiring distribution for its silicon.

And a note on the headline’s question. Jeff Bezos is executive chairman; he is not in the diligence room. He does not need secret knowledge here. What Amazon “knows” is simply the value of this asset inside its own war, a number Anthropic could never see from the outside.

Two buyers, two games

This is the part founders should tattoo on their forearms. Anthropic and Amazon looked at the same company and played two different games. Anthropic was pricing an asset: what is Decart worth to us as a business, on its own merits? Amazon is pricing optionality: what is it worth to own the adapter that makes our nine-figure chip bet work?

The billion-dollar gap is not a math error. It is the difference between standalone value and strategic value, and in acquisitions that gap is where deals die or get wildly overpriced. Anthropic’s no was disciplined. Amazon’s maybe is strategic. Both can be right at the same time because they are answering different questions.

The founder lesson: a passed deal is not a ceiling

Most founders treat a passed deal as a verdict. A serious buyer looked, passed, and therefore the company is worth less than the ask. Decart just proved the opposite. One month after Anthropic walked at $6 billion, Amazon is talking $7 billion. The asset did not change in thirty days. The buyer did.

The lesson is to know which buyer you are talking to before you set your price. A peer acquirer pays for what you are. A strategic giant pays for what you unlock. Those are different numbers, sometimes a billion dollars apart. When Liang Wenfeng rewrote his own fundraising rules as DeepSeek’s facts changed, he was playing the same game: price the company you are becoming, not the one you were.

The bottom line

Watch the trajectory of the number, not just the number. Four billion in May. A $6 billion pass in September. Seven billion in talks in October. That slope tells you where AI infrastructure value is pooling: anything that loosens Nvidia’s grip.

And remember the deal is still just talks. If it falls apart, that tells its own story: two elite buyers passing in two months would raise real questions about what diligence keeps finding. If it closes, it confirms the new rule of the AI buildout. The hyperscalers are no longer just renting compute. They are buying the picks and shovels at whatever price keeps them out of Nvidia’s toll booth.
