Anthropic is in talks to acquire Israeli AI startup Decart for about $6 billion, a potential deal that would be the largest acquisition in the history of the Claude developer and mark its first major step into Israel's technology ecosystem. The acquisition would give the AI company a team of roughly 100 employees and technology aimed at making AI systems faster and more efficient, addressing a shared industry problem where demand for models is growing faster than computing infrastructure. Decart develops AI infrastructure and optimization technology alongside its own AI models. The deal remains in an early stage and could still fall through, according to people familiar with the negotiations cited by Bloomberg and Reuters. If completed, Decart's team is expected to join Anthropic's inference and performance organization. The possible transaction follows Anthropic's acquisition four months ago of Runhouse, an AI infrastructure startup whose founding team included Israeli entrepreneur Josh Lewittes and which counted Israeli venture capital firm Hetz Ventures among its investors. That deal was conducted primarily in Anthropic shares at a relatively modest valuation. Runhouse had only around 10 employees and operated as a fully distributed company without a central office. Hetz Ventures partner Guy Fighel said at the time that "the company is looking very, very closely at the Israeli market."
