Amazon in Talks to Buy AI Startup Decart in Deal Valued Around $7 Billion

What happened

Amazon's talks to acquire Decart could value the startup at around $7 billion, The Wall Street Journal reported, citing people familiar with the matter. The people said a deal could come together soon, assuming the talks do not fall apart or another suitor does not emerge. Israeli outlet Calcalist reported earlier this month that Decart was in advanced talks to be sold to a major technology company. Bloomberg also reported that Anthropic had been in talks in September to buy Decart for about $6 billion and performed due diligence, before deciding against it.

Decart is based in San Francisco and was founded in 2023 by three Israeli engineers: brothers Dean and Orian Leitersdorf, and Moshe Shalev. Its software makes it easier for developers to switch AI workloads between different AI chips. The company is also developing world models called Lucy and Oasis, which can generate and simulate real-world 3-D environments.

Amazon has developed its own AI chip, Trainium3, in competition with Nvidia's graphics processing units. Amazon Web Services gave Decart early access to Trainium3 in 2025 after meeting the company and being impressed by its founders, The Wall Street Journal has previously reported.
