Amazon in talks to buy AI startup Decart for about $7 billion

Amazon is in talks to acquire the artificial intelligence startup Decart for around $7 billion, the Wall Street Journal reported, citing people familiar with the matter. A deal could be reached soon if the talks do not collapse or another bidder does not emerge, according to the report. Amazon and Decart have not publicly confirmed the negotiations. The reported price is a sharp increase on the company's valuation of close to $4 billion in May, according to PitchBook data cited by the Journal. That is a premium of about 75 percent in under five months. Decart was founded in 2023 and is headquartered in San Francisco, with operations in New York and Tel Aviv. Its main product, the Decart Optimization Stack, lets developers run AI workloads on Nvidia graphics chips, Google's TPUs or Amazon's own Trainium processors without rebuilding their software for each one. The company also builds its own models for editing live video and generating simulated environments. Amazon already has close ties to the startup. Its cloud arm AWS gave Decart early access to its Trainium3 chip in 2025, and the two companies signed a commercial agreement in May. Anthropic examined Decart for several weeks in September before walking away from a deal worth roughly $6 billion. Neither company has explained publicly why those talks ended. For Amazon, the deal would follow a familiar pattern. It bought the Israeli chip startup Annapurna Labs in 2015 for a reported $350 million, and that team went on to build the processors behind much of its cloud business.
