Anthropic reportedly walks away from Decart deal

Anthropic has reportedly walked away from a plan to acquire Decart, the Israeli AI startup focused on infrastructure optimization and real-time world models. Calcalist says the Claude maker explored the acquisition, advanced far enough to conduct due diligence, and ultimately decided not to pursue the transaction.

That is a reversal from earlier reporting. Reuters and Bloomberg previously reported that Anthropic was in talks to buy Decart, and Calcalist later said the deal discussions had moved around 7B USD, with Decart’s founders and Sequoia favoring Anthropic despite a higher reported Nvidia offer.

The deal is not happening for now, according to the new report. The practical signal is still important: frontier labs are looking for ways to reduce inference costs and improve chip utilization as model demand grows. Buying an infrastructure team like Decart would have put that work closer to Claude’s biggest operating constraint.

For readers, the update matters less as M&A drama and more as a reminder that the AI race is increasingly about compute economics. Even when a deal collapses, the target says a lot about where large labs feel pressure.
