The short version: Tenstorrent, the Santa Clara AI chip startup led by semiconductor veteran Jim Keller, closed a $1.5 billion Series E funding round on October 19, 2026, at a $6.2 billion post-money valuation, more than doubling its value since late 2024. The round was led by Trace Capital and Innovation X, and the money will scale production of Tenstorrent’s Galaxy AI servers and advance the open RISC-V chip designs it licenses to companies including Samsung and LG.

Who is Tenstorrent?
Tenstorrent is an AI computing company that designs processors, builds complete AI servers, and licenses its chip designs to other companies. Its distinguishing bet is architectural openness: the processors are built on RISC-V, the open-source instruction set that lets companies design chips without paying license fees to proprietary ecosystems such as Arm, and the company ships an open-source software stack so developers can run models on hardware they actually control.
The company is led by CEO Jim Keller, one of the most respected chip architects in the industry. Keller previously led Tesla’s effort to develop a self-driving chip for its electric vehicles and held key design roles at Apple, where he worked on the A4 and A5 processors, and at AMD, where he was the architect behind the Zen architecture. That track record is a large part of why investors keep writing checks.
Tenstorrent sells what it calls one architecture at every size: a single accelerator card or developer workstation, a full rack, a giant cluster, or just a license to use its AI and CPU designs inside your own silicon. In Keller’s own words from the announcement: “We built one architecture and sell it at every size.”
What the $1.5 billion is for
According to the company’s announcement, the new capital has three main jobs:
- Deploy Galaxy servers at scale. Tenstorrent’s Galaxy systems combine dozens of its AI chips into servers aimed at running chatbots, coding assistants and video generators. Scaling manufacturing is the most capital-intensive part of the plan.
- Keep serving open-weight models. The company is positioning its hardware as the home for openly available AI models, across both large language models and video generation, where buyers want to run workloads on their own infrastructure instead of renting someone else’s cloud.
- Advance its licensable chip IP. Tenstorrent licenses its RISC-V CPU and AI core designs to chip designers, with Samsung and LG named as customers. More funding means faster development of the next generations of that IP.
Ben Mahdavi, founder of lead investor Trace Capital, said the firm was backing “decades of hands-on silicon, software, and IP experience” as Galaxy continues to scale.
Why investors are betting on an Nvidia alternative
Nvidia still dominates the market for AI accelerators, and many buyers are uneasy about relying on a single supplier with premium pricing and a closed software ecosystem. Tenstorrent’s pitch is that the AI chip race is no longer only about raw speed. Openness and ownership are becoming selling points in their own right: hardware and software the customer can inspect, modify and run on premises.
The timing helps. Enterprise buyers evaluating AI infrastructure increasingly want a credible second source, and open-weight models give them a reason to run workloads outside the big clouds. A funding round this large signals that institutional investors believe open-architecture AI hardware can become a genuine second ecosystem rather than a niche hobby. For context on where the AI hardware market is heading, see our coverage of NVIDIA’s RTX Spark launch and Microsoft’s Surface Laptop Ultra, both of which show how aggressively AI compute is moving into every tier of device.
The takeover talks that never happened
The raise comes just months after reports that Qualcomm was in talks to acquire Tenstorrent in a deal potentially worth between $8 billion and $10 billion, a story first reported in June citing The Information. Bloomberg later reported that takeover discussions involving both Intel and Qualcomm had taken place.
No sale happened. According to Bloomberg’s reporting, CEO Jim Keller told the outlet that the company had decided to pursue funding rather than a sale, and cited a May demonstration featuring Galaxy servers running high-performance DeepSeek models as a turning point. The $6.2 billion valuation is still below the rumored acquisition range, but it keeps Tenstorrent independent, which is exactly what its open-architecture positioning requires. A startup selling freedom from proprietary ecosystems would have a harder story to tell inside one of the giants.
What it means for the AI chip race
For buyers, the practical takeaway is simple: a second credible supplier of AI compute is getting much better funded. That means more negotiating leverage against incumbent pricing, more hardware tuned for open-weight models, and more on-premises options for companies that cannot or will not send data to the cloud. The open-weights trend itself keeps accelerating, from community models to releases like Meta’s open-weight Muse Spark, which all need somewhere affordable to run.
For the industry, Tenstorrent’s rise is the clearest evidence yet that investors see room for an open challenger in a market Nvidia has owned. Whether $6.2 billion turns out to be a rational price for that optionality depends on execution: shipping Galaxy servers at volume, proving real-world performance against entrenched competition, and turning licensing customers like Samsung and LG into recurring revenue. The money buys Tenstorrent the chance to find out.
