Keller told Bloomberg the company chose to stay independent after acquisition interest, and the money goes to chips built for serving open-weight models and video generation. ## Key facts - Round: $1.5B Series E, led by Trace Capital (new firm of Quiet Capital co-founder Ben Mahdavi) and Innovation X; also Cadence Ventures, Eclipse, Fidelity, SanDisk, T. Rowe Price - Valuation: $6.2B, more than double the $2.6B of late 2024 (when it raised $700M, per Techmeme's summary of Bloomberg) - Per TechCrunch: about five months earlier Intel and Qualcomm reportedly showed acquisition interest at valuations up to $5B; Keller told Bloomberg the company stayed independent after its Galaxy servers showed they could run DeepSeek models - Use of funds: scaling inference chips for open-weight models and for video generation ## What happened Tenstorrent closed one of the largest 2026 rounds for a non-Nvidia AI chip company, positioning its hardware for serving open-weight models rather than frontier training. ## Why it matters Investor money is following the shift of AI spending toward inference, where cheap open-weight models such as DeepSeek's run on hardware other than Nvidia's. ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 172 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 111 days after its cutoff - Gemini 4 Argon (training cutoff March 2026): 202 days after its cutoff - Grok 4.7 (training cutoff May 2026): 141 days after its cutoff ## Sources 1.
