Tenstorrent raises $1.5 billion Series E at $6.2 billion valuation to scale Galaxy AI servers

Reuters reported on October 19, 2026, that Tenstorrent closed a $1.5 billion Series E at a $6.2 billion post-money valuation, more than doubling its valuation from December 2024. The round was led by Trace Capital and Innovation X, with participation from Cathie Wood's ARK Invest, Sandisk, Morgan Stanley, T. Rowe Price and Tether Investments, among others. The Santa Clara, California based company said the capital will be used to scale production of its Galaxy servers, which combine dozens of its AI chips to power applications including chatbots, coding assistants and video generators.

Tenstorrent develops AI chips and software using RISC-V, an open-source chip architecture that enables companies to design processors without license fees and reduce dependence on proprietary chip ecosystems such as Arm's. The company is led by Jim Keller, a prominent chip architect who previously led Tesla's efforts to develop a self-driving chip for electric vehicles and held key design roles at Apple and AMD, according to Reuters. Its pitch rests on integrated systems, full-stack software and custom server architectures rather than on selling standalone chips alone.

The funding history shows how far the company has traveled. The Globe and Mail reported on October 19, 2026, that Tenstorrent raised $693 million in late 2024 at a $2 billion valuation and more than $200 million in spring 2021, making the Series E its third nine-figure financing. The company was founded in Toronto 10 years ago but relocated to the United States in 2023 after its first investor, Jim Keller, became chief executive officer, the Globe and Mail reported. Its Toronto office remains one of its largest hubs, and the company also operates in Silicon Valley, Tokyo, Belgrade and Bangalore.

Bloomberg reported on October 19, 2026, that Tenstorrent stayed independent after attracting takeover interest earlier this year. The Globe and Mail reported on October 19, 2026, that Intel and Qualcomm had both tried to buy Tenstorrent for upward of $5 billion. Management opted for organic expansion after a May technical milestone showed its Galaxy servers could effectively run high-performance AI models developed by DeepSeek, according to Bloomberg. That decision now frames the company's next phase: it has fresh capital, a public valuation and a mandate to prove that an open architecture can win commercial business at scale.

Key Facts

The Series E was led by Trace Capital and Innovation X. Bloomberg reported that Trace Capital was started this year by Quiet Capital co-founder Ben Mahdavi, while the Globe and Mail described it as Los Angeles based and founded by former NFL linebacker turned investor Ben Mahdavi. Innovation X is based in New York, according to the Globe and Mail. The investor list also includes Fidelity, ARK Invest, T. Rowe Price Group, Tether Investments, Sandisk, Morgan Stanley and Cadence Design Systems' venture arm Cadence Ventures, along with Maverick Silicon, Agostinelli Group, Eclipse Venture Equity, Protagonist Management and others.

DataCenterDynamics reported on October 19, 2026, that Galaxy servers pair 32 of the company's RISC-V Blackhole processors with Tensix AI cores and offer 23 petaflops of FP8 compute performance. The servers began shipping in April 2026. Tenstorrent said it will use the funding to scale manufacturing and introduce new generations of the Galaxy line while increasing its global workforce. The company also licenses its TT-Ascalon RISC-V CPU and Tensix AI cores to chip designers including Samsung and LG, according to its announcement.

Bloomberg reported that Tenstorrent is a roughly 1,150-employee startup focused on general-purpose AI computing and targeting buyers whose order volumes fall outside the scope of dominant market leaders. Keller said the company built one architecture and sells it at every size, according to DataCenterDynamics. The company's backers include Bezos Expeditions, Samsung, LG Electronics, Hyundai Motor Group and Fidelity, its announcement said. Tenstorrent operates from Santa Clara, Austin, Toronto, Belgrade, Tokyo and Bangalore.

The valuation jump is sharp. Reuters reported that the prior round raised more than $693 million in December 2024 at a $2 billion pre-money valuation. DataCenterDynamics reported that the Series D valued Tenstorrent at more than $2.6 billion, and Bloomberg put the 2024 valuation at $2.6 billion. The new $6.2 billion post-money figure is more than double that level. The company's Galaxy systems are aimed at the fast-growing inference market for open-weight models, including large language models behind chatbots and agents and AI video generation, according to the Globe and Mail.

Analysis

What this really means is that investors are willing to pay a much higher price for a credible, independent alternative to Nvidia and AMD at the infrastructure layer, even before Tenstorrent has disclosed the kind of revenue or customer concentration that usually supports a $6.2 billion valuation. The $1.5 billion raise is more than twice the size of the $693 million raised in December 2024, and it gives the company room to fund manufacturing, software work and global hiring without returning to the market immediately. That is a strong statement of confidence from a group that includes Fidelity, T. Rowe Price, Morgan Stanley, ARK Invest and Tether Investments.

The strategic logic is not simply about selling chips. Tenstorrent is using RISC-V to avoid license fees and reduce dependence on proprietary ecosystems such as Arm's, while selling integrated systems, full-stack software and custom server architectures. Bloomberg reported that the company is positioning itself against Nvidia and AMD by offering lower pricing and greater design customization. That combination matters most for buyers whose order volumes fall outside the scope of dominant market leaders. If Tenstorrent can serve those customers with a complete system rather than a component, it can compete on flexibility and cost rather than on raw scale alone.

The bigger picture here is that the $6.2 billion post-money valuation is also a referendum on independence. The Globe and Mail reported that Intel and Qualcomm had both tried to buy Tenstorrent for upward of $5 billion. The new valuation is above that reported takeover figure on a post-money basis, which suggests management and its investors believe organic expansion can create more value than a sale. The risk is that the premium now depends on execution: shipping Galaxy servers at scale, adding new generations and converting technical milestones into repeatable customer demand. A valuation above a reported bid is not proof of a better outcome; it is a promise that the company must keep.

The capital also raises expectations for Tenstorrent's IP business. Its announcement says it licenses the TT-Ascalon RISC-V CPU and Tensix AI cores to chip designers including Samsung and LG, and its investor base includes Samsung, LG Electronics and Hyundai Motor Group. Those relationships give it strategic depth beyond a single server product. Still, the company faces the cost of manufacturing, software support and global hiring, and it must do so against Nvidia and AMD, both of which have far greater resources. The 23 petaflops FP8 specification is a useful marker, but it is not by itself a guarantee of performance on every model or workload. The next phase will test whether Tenstorrent can turn a strong specification and a large war chest into durable commercial traction.

Why It Matters

The round matters because it gives RISC-V a better-funded commercial flagship. Tenstorrent's argument is that companies can design processors without license fees and reduce dependence on proprietary chip ecosystems such as Arm's. If Galaxy servers gain traction, that argument becomes more credible for other chip designers and for customers that want an alternative to the dominant GPU suppliers. The company's licensing work with Samsung and LG adds another channel: even buyers that do not purchase full servers may adopt its CPU or AI core IP.

It also matters for the competitive landscape in AI inference. Tenstorrent is targeting open-weight models, including the large language models behind chatbots and agents and AI video generation, according to the Globe and Mail. That is a fast-growing part of the market, and it is not identical to the training workloads where Nvidia is strongest. Tenstorrent's emphasis on integrated systems, full-stack software and custom server architectures gives it a different angle from merchants that sell chips alone. The $1.5 billion round gives it the resources to pursue that angle at a time when customers are looking for more choices and lower costs.

For Toronto and for the broader startup ecosystem, the deal is a reminder that Canadian-founded hardware companies can scale into global businesses. Tenstorrent was founded in Toronto 10 years ago and relocated to the United States in 2023 after Jim Keller became CEO, the Globe and Mail reported. Its Toronto office remains one of its largest hubs, according to the Globe and Mail. The company now operates from Santa Clara, Austin, Toronto, Belgrade, Tokyo and Bangalore. The round shows that capital can flow to a Toronto-founded company even after it moves its headquarters, and it puts a spotlight on the talent base that remains in the city.

Next Up

Tenstorrent said it will use the funding to deploy Galaxy servers at scale, continue serving open-weight models across large language models and video generation, and advance the AI and CPU IP it licenses to customers designing their own silicon. DataCenterDynamics reported that the company will scale manufacturing and introduce new generations of Galaxy servers while increasing its global workforce. The company also said it will use the capital to scale production of its Galaxy servers, which combine dozens of its AI chips for applications including chatbots, coding assistants and video generators.

The next test is execution. Galaxy servers began shipping in April 2026, so the company now has to show that the 32-processor, 23-petaflop FP8 design can win repeat orders and support real customer workloads. Investors will watch hiring, manufacturing scale and new product generations, while customers will watch pricing, customization and software support. The $6.2 billion valuation gives Tenstorrent leverage and attention, but it also sets a high bar for the shipments and customer wins that must follow.
