- Anthropic is in talks to acquire Decart AI — a startup that makes world models and chip efficiency software — for approximately $6 billion, according to people familiar with the matter; the deal would be Anthropic’s largest known acquisition and would close ahead of the company’s highly anticipated IPO.
- Decart’s chip efficiency technology is the strategic core of the acquisition: its software helps AI accelerators work more efficiently, directly reducing the cost of training and inference — a critical capability for Anthropic, which has been spending aggressively on computing power to develop new models and serve a rapidly growing customer base.
- Decart’s world models — which simulate real-world physics using AI trained on text and millions of hours of video — enable applications from autonomous driving to live fashion try-on; its Lucy AI model can generate real-time, photorealistic video of a person wearing different clothing from a live feed, solving a long-standing e-commerce rendering challenge; eBay, an investor in Decart, is also a customer.
- The $6 billion price tag represents a significant premium over Decart’s May 2026 valuation of approximately $4 billion — itself up from $3.1 billion in August 2025 — reflecting the intense competition among frontier AI labs to acquire infrastructure talent capable of reducing compute costs as model training expenditures spiral toward the hundreds of billions.
What Happened?
Anthropic is in acquisition discussions with Decart AI, a startup founded in 2023 by Israeli engineers and brothers Dean and Orian Leitersdorf and Moshe Shalev, at a valuation of approximately $6 billion. Decart raised $300 million in May 2026 in a round led by Radical Ventures, with Nvidia, Atreides Management, Valor Equity Partners, and Adobe Ventures participating; prior investors Sequoia Capital and Benchmark also joined. Decart’s team would integrate into Anthropic’s inference and performance organization, one of the people said. The deal has not been finalized and could still fall through. Separately, Israeli outlet Calcalistech reported Decart had also been in discussions with SpaceX — a claim Elon Musk dismissed as “fake news” on X.
Why It Matters?
The Decart acquisition reflects a strategic reality that is reshaping the frontier AI industry: raw model capability is no longer the only moat. The ability to serve models cheaply and at scale — inference efficiency — is increasingly the differentiating factor between AI companies that can build sustainable businesses and those that bleed cash indefinitely. Anthropic and OpenAI have each committed to spending tens, if not hundreds, of billions on data centers and chips; technology that makes those chips work more efficiently is worth a substantial premium. Decart’s world model capabilities are an additional strategic asset, giving Anthropic a foothold in simulation and video AI that could open new product categories beyond language models. The acquisition also signals that Anthropic is using pre-IPO capital aggressively to lock in talent and technology before the public market scrutiny of post-IPO cost discipline kicks in.
What’s Next?
If the deal closes, watch for Decart’s chip efficiency technology to begin appearing in Anthropic’s infrastructure roadmap — potentially reducing per-token costs and improving the economics of Claude API pricing. Decart’s world model technology could eventually surface in Anthropic products aimed at video, simulation, or embodied AI. For the broader AI M&A market, a $6 billion acquisition price for a three-year-old startup with strong infrastructure credentials will reset expectations for similar deals — and accelerate competition among OpenAI, Google DeepMind, and Meta AI to acquire comparable teams before they are absorbed by rivals. Anthropic’s IPO timeline remains the key overhang: the company will want to demonstrate the acquisition is accretive before it files.
