Tenstorrent raises $1.5 billion at a $6.2 billion valuation to take on Nvidia

Tenstorrent has closed $1.5 billion in Series E funding at a $6.2 billion post-money valuation, the company announced on October 19, 2026. The round was led by Trace Capital and Innovation X, and the ambition is stated without blushing: challenge Nvidia.

The company says the equity raise will fund volume manufacturing and global commercial expansion "as chip designers, sovereign players, and inference platforms move to own their AI compute." It will also advance AI and CPU IP licensing. According to Reuters, as carried by Boursorama, the money will scale production of Galaxy servers, which combine dozens of Tenstorrent's chips to power chatbots, coding assistants and video generators.

That is a lot of money, a lot of ambition and a lot of very serious people in one press release. Let us go through the room.

The numbers, and a valuation that more than doubled

The $6.2 billion figure more than doubles Tenstorrent's valuation from December 2024, per Reuters. That earlier round raised more than $693 million at a $2 billion pre-money valuation, led by Samsung Securities and AFW Partners, according to the same report.

Bloomberg, via Techmeme, tells the baseline slightly differently: a valuation up from $2.6 billion after raising $700 million in 2024. The two accounts count the starting line differently, but both end in the same place. The valuation has climbed past double.

There is also the matter of who wanted to own the company outright. The Globe and Mail notes that the round follows reports earlier this year that Intel and Qualcomm had both tried to buy Tenstorrent for upward of $5 billion. The terms and dates of those reported approaches are not public in the material available. Whatever happened behind closed doors, Tenstorrent has now announced a $1.5 billion funding round.

The guest list

The lead investors are two American private capital firms. Trace Capital is based in Los Angeles and was founded by former NFL linebacker Ben Mahdavi, a career pivot from the gridiron to the cap table. Innovation X is based in New York.

Then comes the participation list, and it is glorious. New and existing investors include:

• Fidelity Management & Research Company
• T. Rowe Price
• Morgan Stanley
• Cathie Wood's ARK Invest
• Tether Investments
• Sandisk
• Virtu Financial and XTX Markets
• Agostinelli Group, Brett Barna, Cadence Ventures, Eclipse, Maverick Silicon, Protagonist and Troluce Capital

The announcement does not break down how much each backer put in, including the split between the two leads and everyone else.

Why the open-source bet matters

Tenstorrent builds AI chips and software on RISC-V, an open-source architecture. Per Reuters, it lets companies design processors without licensing fees and reduces reliance on proprietary ecosystems such as Arm's. The company says it sells AI compute at every level of the stack, from a single card or workstation to racks, superclusters and custom IP, with an open-source software stack. Its pitch is that developers can run frontier models locally and enterprises can deploy models on-prem.

The man at the helm is Jim Keller, the chief executive. Reuters says he previously led Tesla's effort to build a self-driving chip for electric vehicles and held key design roles at Apple and AMD, among others. According to the Globe and Mail, Tenstorrent was founded in Toronto 10 years ago and relocated to the United States in 2023 after Keller, its first investor, became CEO.

Toronto remains one of its largest hubs, with 200 of the company's 1,000 employees. It also has operations in Silicon Valley, Tokyo, Belgrade and Bangalore. Where exactly the headquarters sits depends on who you read: Reuters says Santa Clara, California, while the Globe and Mail says Austin, Texas.

What it means, and what to watch

The plain reading is that big money has decided Nvidia deserves a serious, open-architecture challenger, and has put $1.5 billion behind the attempt. Valuations are not market share. But a company that two chip giants reportedly tried to buy, and that Fidelity and Morgan Stanley just backed, is not a hobby.

The open questions are the practical ones. The announcement does not say which manufacturing partners or foundries will build the chips and Galaxy servers. It gives no date for when the scaled-up servers will ship to commercial customers. And it offers no benchmark showing how Tenstorrent's hardware stacks up against Nvidia's in a head-to-head.

Funding is a promise. Shipping is the proof. Keep your eyes on the factory floor.
