Elon Musk Denies Reports of Buying Israeli AI Startup Decart
Elon Musk has denied reports that SpaceX is in advanced talks to acquire the Israeli artificial intelligence startup Decart for $6-7 billion. Musk responded to a post on X (formerly Twitter) claiming the deal was imminent by calling it "fake news." The original post, which suggested SpaceX was the prospective buyer and that the deal could close within a week, was deleted by its author after Musk's denial.
The rumors originated from a report by Calcalist stating Decart was nearing a sale to a major international tech company valued at around $6 billion, without naming the buyer. Industry sources speculated SpaceX might be the purchaser, with the transaction expected to take place in the United States. Other potential buyers mentioned included Amazon, cloud company Nebius, and Nvidia, which is both an investor and partner of Decart.
Decart was founded in September 2023 by Dr. Dean Leitersdorf, CEO, and Moshe Shalev, VP of Product, both former members of Israel's elite Unit 8200. The company develops real-time world models and the infrastructure needed to run them at scale. In May 2026, Decart raised $300 million in a funding round led by Radical Ventures, with participation from Nvidia and others, boosting its valuation to nearly $4 billion. At that time, Decart also announced strategic partnerships with Amazon as a client and Nvidia as an investor and business partner.
Musk had previously expressed interest in Decart's AI capabilities, commenting positively on their Oasis game launch with Etched, which showcased real-time video generation. According to Calcalist, Musk has been in contact with Decart's founder since then. Decart has not issued a public response to the acquisition rumors.
Summary: Elon Musk refuted claims that SpaceX is acquiring Israeli AI startup Decart for $6-7 billion, calling the reports "fake news." The startup, valued at nearly $4 billion after a recent funding round, is reportedly in talks with several international tech companies, but no deal has been confirmed.
