Decart was founded in 2023 by brothers Dean and Orian Leitersdorf and Moshe Shalev, with ties to Israel. It raised $300 million in May 2026 in a round led by Radical Ventures, with Nvidia joining as an investor, valuing the company at nearly $4 billion. Other backers include Sequoia Capital and Benchmark. Amazon Web Services gave Decart early access to its Trainium3 chip in 2025, and Decart's video model ran live on Trainium3 at AWS re:Invent in December 2025. Amazon is also reportedly Decart's largest customer. The deal follows a failed attempt: Anthropic reportedly agreed to buy Decart for roughly $6 billion, completed due diligence, and walked away in September. Nvidia had also pursued an acquisition before Anthropic became the preferred bidder in August. Terms of any Amazon agreement have not been disclosed, and the report has not been confirmed by either company.
For attorneys, the deal sits at the intersection of AI compute and antitrust scrutiny. Software that moves workloads between chips could make it easier for customers to shift work from Nvidia GPUs to Amazon's Trainium processors, which Amazon is pushing as a competitor to Nvidia. Watch for a formal announcement, any HSR filing or regulatory review, and whether a rival bidder re-emerges. The price is also well above Decart's May valuation, which analysts read as a sign of how aggressively cloud providers are paying for tools that reduce dependence on a single chip supplier.
