- Anthropic walked away from a potential $6 billion acquisition of Decart AI after completing due diligence — a disciplined pre-IPO capital allocation decision for a company already managing a $15B credit facility and seeking a SpaceX-scale listing.
- Decart produces software that reduces AI training and inference costs by helping chips work more efficiently — an infrastructure layer Anthropic had been targeting to help its existing compute absorb more demand as Claude usage scales ahead of IPO.
- Decart was valued at ~$4 billion in a May 2026 funding round led by Radical Ventures (with Nvidia, Atreides, Valor Equity, Adobe Ventures, Sequoia, Benchmark, and Zeev Ventures participating) — a $6B acquisition price would have represented a ~50% premium to that valuation.
- The companies may still pursue collaboration opportunities, per sources — suggesting the door is open for a partnership or licensing arrangement that delivers some of the compute-efficiency benefits without the full acquisition cost or equity dilution impact ahead of the IPO.
What Happened?
Anthropic has decided against acquiring Decart AI, Bloomberg reported Monday, walking away after completing due diligence on a deal that had been explored at around $6 billion. Decart, founded in 2023 by brothers Dean and Orian Leitersdorf and Moshe Shalev, builds software that makes AI chips more efficient — both for training models and for inference (running them post-training). The acquisition had been conceived as a way to help Anthropic’s infrastructure absorb surging demand for Claude as it scales toward IPO. The companies may still pursue other collaboration opportunities, per people familiar with the matter.
Why It Matters?
The Decart walkaway is a notable pre-IPO capital discipline signal. Anthropic is already managing a $15 billion revolving credit facility and targeting a public listing that could rival or exceed SpaceX’s $86 billion debut — in that context, a $6 billion acquisition at ~50% premium to Decart’s last round valuation would have been a large, dilutive bet on infrastructure efficiency at exactly the moment investors are scrutinizing Anthropic’s cost structure and path to profitability. Decart’s technology — chip optimization stacks for training and inference — addresses a real cost problem for frontier AI labs, but the capability can potentially be replicated through partnerships, licensing, or internal development at lower cost.
What’s Next?
Decart remains independently valued at ~$4 billion with strong investor backing including Nvidia — which gives it both compute partnership access and a strategic relationship with the dominant AI chip supplier. For Anthropic, the compute-efficiency challenge doesn’t go away: as Claude usage scales and inference costs grow, the pressure to squeeze more performance per chip will intensify. The “collaboration opportunities” language suggests a partnership structure may emerge as an alternative to acquisition. For Decart, remaining independent keeps its optionality open — and with an IPO wave coming in AI, a direct public listing or alternative acquirer (Microsoft, Google, Amazon) remains on the table.
