Amazon is in talks to buy Decart, a San Francisco startup, and a price near $7 billion is under discussion, The Wall Street Journal reported on 12 October. Decart’s software helps developers move workloads from one AI chip to another. Reporters Kate Clark and Lauren Thomas cite people familiar with the matter, and describe the figure as what the deal could be worth.
The logic sits in Amazon’s own product line. The company builds a custom AI chip, Trainium3, that it sells against Nvidia, which still dominates the graphics processors behind the AI boom. A chip only wins customers if developers can adopt it without rewriting their work. Decart’s software exists to remove that cost, so the buyer would be acquiring the tool that makes its own silicon easier to choose.
Amazon Web Services already knew the company. According to the Journal’s earlier reporting, AWS gave Decart early access to Trainium3 in 2025 after meeting the founders and coming away impressed. A relationship that began as a chip customer’s trial would become, if the talks succeed, ownership.
Nothing is agreed. The Journal’s sources said “a deal could come together soon,” but only “assuming talks don’t fall apart or another suitor doesn’t emerge.” Another bidder would change the price and possibly the buyer. Earlier this month, the Israeli outlet Calcalist reported that Decart had entered advanced talks with a major technology company over a sale. We have not independently confirmed that report.
The valuation arithmetic is steep. Investors put a value of nearly $4 billion on Decart in May. A $7 billion price would be roughly 75 percent higher, reached in about five months. Decart has raised more than $400 million from investors including Sequoia Capital, Benchmark, and Radical Ventures, according to PitchBook, so those backers would be looking at a large multiple on the money they put in.
For scale, Amazon’s biggest recent purchases were the $6.5 billion MGM studio deal in 2022 and a roughly $11 billion agreement for Globalstar, a satellite-internet rival to Starlink, announced this year. Seven billion dollars would land between the two. It would also be money spent on software rather than a studio or a satellite fleet.
Decart was founded in 2023 by three Israeli engineers: brothers Dean and Orian Leitersdorf, and Moshe Shalev. It also builds world models called Lucy and Oasis, which generate and simulate three-dimensional environments. That is a second business, and by the Journal’s account the chip-portability software is what draws Amazon.
The sticking point for any customer is lock-in. If Amazon owns the layer that lets code hop between chips, developers will want to know whether it keeps working as well for Nvidia hardware as it does for Trainium3. The Journal’s story does not say what Amazon intends. Teams that have kept their options open across chip vendors should ask now what Decart’s roadmap looks like under new ownership, before a signature makes the question moot.
