Anthropic ended negotiations to acquire Decart AI for $6 billion after completing due diligence, according to sources familiar with the matter. The talks terminated without a signed letter of intent. Both companies indicated a partnership structure remains under discussion.
Decart AI, a Bay Area startup founded in 2023, builds real-time generative AI for gaming environments. The company demonstrated Oasis, a playable Minecraft-style world model that generates game states frame-by-frame without a traditional engine. Anthropic's interest centered on acquiring inference optimization techniques and real-time multimodal capabilities that Decart developed for interactive 3D environments. The $6 billion valuation would have placed Decart among the top five largest AI acquisitions globally, exceeding Microsoft's $4 billion investment in Mistral AI and approaching Google's reported $7 billion stake in Anthropic itself.
The termination signals two structural tensions in foundation model M&A. First, valuation arbitrage between generative AI tooling companies and foundation model builders has compressed. Anthropic's last disclosed valuation stood at $60 billion in a December funding round led by Lightspeed Venture Partners. A $6 billion bolt-on acquisition represents 10% of enterprise value for capabilities that could be replicated internally within 18-24 months, according to three AI research leads consulted on competitive dynamics. Second, regulatory scrutiny of vertical integration in AI infrastructure has intensified. The FTC opened inquiries into Microsoft's partnerships with OpenAI and Anthropic in January. A $6 billion acquisition of a specialized inference company would have drawn immediate review under pre-merger notification thresholds.
Decart's core value proposition—real-time latency under 50 milliseconds for generative 3D environments—matters less to Anthropic's current product roadmap than initially assessed. Anthropic's Claude models target enterprise workflow automation and document reasoning, not interactive gaming. The company's Q1 2025 priorities center on expanding context windows beyond 200,000 tokens and reducing hallucination rates in multi-turn conversations, according to its public research disclosures. Decart's inference stack optimizes for visual coherence and frame consistency, adjacent but not directly transferable to text-based reasoning workloads.
Allocators should track three follow-on events. First, whether Decart raises a Series B within 90 days at a valuation above or below the $6 billion negotiation benchmark. A down-round would confirm Anthropic's due diligence uncovered material concerns. Second, monitor Anthropic's hiring in real-time inference and multimodal model optimization through April. Internal buildout would indicate the company assessed Decart's technology as replicable rather than defensible. Third, watch for partnership announcements in the gaming vertical from Meta or ByteDance, both of which compete directly with Anthropic in generative AI and have stronger distribution in interactive entertainment.
The deal's collapse leaves Decart with $21 million in disclosed funding and a public valuation anchor that complicates future financing. Partnership terms rarely carry the same enterprise premium as acquisition multiples.
The takeaway
Anthropic's $6B Decart termination suggests acquirer skepticism on inference stack defensibility and vertical fit in gaming AI.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
