Tenstorrent Raises $1.5B Series E at $6.2B to Scale Galaxy Servers

Tenstorrent closed a $1.5 billion Series E at a $6.2 billion post-money valuation, led by Trace Capital and Innovation X, according to the company’s October 19, 2026 announcement. The money goes to deploying its Galaxy servers at scale and to the RISC-V CPU and AI core IP it licenses to chip designers.

The numbers on the wire

• $1.5 billion Series E; $6.2 billion post-money.
• Leads: Trace Capital (founded in 2026 by Quiet Capital co-founder Ben Mahdavi) and Innovation X.
• Participants named: Agostinelli Group, ARK Invest, Brett Barna, Cadence Ventures, Eclipse, Fidelity Management & Research Company, Maverick Silicon, Morgan Stanley, Protagonist, Sandisk, T. Rowe Price, Tether Investments, Troluce Capital, Virtu Financial and XTX Markets.
• Prior round: $693 million+ Series D at a $2 billion pre-money valuation in December 2024, led by Samsung Securities and AFW Partners. That implies roughly $2.7 billion post-money (Ultrathink arithmetic), so the new mark is about 2.3 times higher in under two years.
• Revenue, unit shipments and customer counts were not disclosed.

What Tenstorrent sells

Tenstorrent, led by CEO Jim Keller, builds RISC-V-based AI processors and sells them at every size: single cards and workstations, racks, superclusters, and licensed IP. Its TT-Ascalon RISC-V CPU and Tensix AI cores are licensed to chip designers including Samsung and LG. The software stack is open source, and the company pitches on-prem deployment of open-weight models for LLMs and video generation.

“We built one architecture and sell it at every size,” Keller said in the release. “The future of compute is open, scalable, and owned by the people building on it.”

Reuters describes Galaxy as servers that combine dozens of Tenstorrent chips to run chatbots, coding assistants and video generators.

Why it matters

Tenstorrent is betting that one architecture can be sold three ways at once: as servers to inference platforms and sovereign buyers, as hardware to developers, and as IP to companies building their own silicon. The investor list mixes crossover funds (Fidelity, T. Rowe Price, Morgan Stanley) with trading firms (XTX Markets, Virtu) and a flash-memory maker (Sandisk).
