Tenstorrent said on Monday, October 19, 2026, that it has raised $1.5 billion in a late-stage Series E funding round that values the AI chip startup at $6.2 billion post-money — more than double its valuation from December 2024. Why it matters: investors are still writing very large checks for credible alternatives to the dominant AI chip stacks, and Tenstorrent’s bet is on open architecture rather than a proprietary ecosystem.

What happened
The Santa Clara, California-based company announced the Series E on Monday. The round was led by Trace Capital and Innovation X. Other backers in the round included Cathie Wood’s ARK Invest, SanDisk, Morgan Stanley, T. Rowe Price and Tether Investments, according to Reuters.
Tenstorrent said it will use the new funding to scale production of its Galaxy servers. Those systems combine dozens of the company’s AI chips into a single server, aimed at powering applications such as chatbots, coding assistants and video generators.
The details: an open-architecture chip bet
Tenstorrent develops AI chips and the software to run them using RISC-V, an open-source chip architecture. Because RISC-V carries no licensing fees, companies designing on it can reduce their dependence on proprietary chip ecosystems such as Arm’s. That open foundation is the core of Tenstorrent’s pitch to buyers who want AI compute without locking themselves deeper into a single vendor’s stack.
The company is led by CEO Jim Keller, a prominent chip architect who previously led Tesla’s efforts to develop a self-driving chip for its electric vehicles and held key design roles at Apple and AMD, among others.
For scale, Tenstorrent’s previous round raised more than $693 million in December 2024 at a $2 billion pre-money valuation, in a financing led by Samsung Securities and AFW Partners. Monday’s $6.2 billion post-money valuation more than doubles that mark in under two years.
Why it matters
Most AI workloads today run on a small number of chip platforms, and that concentration shapes prices, availability and bargaining power for everyone building AI products. A $1.5 billion raise does not by itself change that balance — Tenstorrent still has to ship servers at scale and win workloads away from entrenched rivals — but it gives the company the capital to try. For buyers, the practical takeaway is simple: well-funded, open-architecture alternatives keep getting stronger, which is good news for anyone negotiating AI compute costs. Everything AI, tested — we will be watching whether Galaxy server deployments, not just funding headlines, follow from this round.
