Tenstorrent Lands $1.5B to Take On Nvidia With Open AI Chips

AI chip startup Tenstorrent has closed a $1.5 billion Series E round at a $6.2 billion valuation, the company announced on October 19. The Tenstorrent funding gives Jim Keller’s company fresh cash to build its Galaxy AI servers at scale and push its open, RISC-V based alternative to Nvidia hardware.

Inside the Tenstorrent Funding Round

The round was led by Trace Capital and Innovation X. The $6.2 billion figure is a post-money valuation, meaning it includes the new cash.

That valuation more than doubles where the company stood after its last raise. In December 2024, Tenstorrent raised $693 million in a Series D that valued it at more than $2.6 billion, with backers that included Bezos Expeditions and Samsung Securities.

Who Put Money In

The investor list mixes big asset managers, chip-industry players and trading firms. New and existing backers in the Series E include:

  • ARK Invest, Fidelity Management and Research Company, and Morgan Stanley
  • Accounts advised by T. Rowe Price
  • Chip and storage names such as Cadence Ventures, Maverick Silicon and Sandisk
  • Trading and crypto firms including XTX Markets, Virtu Financial and Tether Investments
  • Venture firms such as Eclipse and Protagonist

One backer, Protagonist, said it was doubling down after the company’s video generation results came in ahead of its expectations. As always with funding announcements, those performance claims come from the company and its investors.

What Tenstorrent Will Do With the New Funding

Tenstorrent says the money will go toward three main goals. It wants to deploy its Galaxy servers at scale, keep serving open-weight models for both chat-style LLMs and video generation, and improve the chip designs it licenses to other companies.

The Galaxy servers started shipping in April of this year. Each one packs 32 of the company’s Blackhole processors, which are built on the open RISC-V standard and use Tenstorrent’s Tensix AI cores.

One Design, Many Sizes

Tenstorrent’s pitch is that it sells the same core technology at every level. You can buy a single card or a workstation, a full rack, a giant cluster, or just a license to use its designs in your own chip.

The company also leans on open-source software. It says developers can run frontier models locally, and businesses can run models on their own servers instead of in someone else’s cloud. CEO Jim Keller summed up the idea simply: “We built one architecture and sell it at every size.”

Why an Open AI Chip Bet Matters

Nvidia still dominates the market for AI chips, and many companies worry about relying on one supplier. Tenstorrent is betting that buyers want hardware and software they can actually own and modify.

Keller gives the company real credibility here. He’s known for designing Apple’s A4 and A5 chips, AMD’s Zen architecture and Tesla’s Full Self-Driving chip.

The AI chip race is no longer only about raw speed. Openness and ownership are becoming selling points too.

A Busy Year for the Company

Tenstorrent has drawn attention from bigger chipmakers this year. Earlier in 2026, reports said Qualcomm had explored buying the company. This new round suggests Tenstorrent plans to keep growing on its own for now.

It isn’t alone in going after Nvidia’s turf. Microsoft is building its own Maia 300 chip, while Nvidia keeps pushing desktop hardware like the RTX Spark for local AI work.

What This Means for You

You probably won’t buy a Tenstorrent server anytime soon. Still, more competition in AI hardware tends to push prices down and give developers more choices over time.

  1. If you run open-weight models, watch for more hardware options outside the usual GPU clouds.
  2. If your business cares about keeping data in-house, on-premise AI gear like this could become easier to buy.
  3. If you follow AI costs, note that chip startups and software tools like doubleAI Maxwell are both attacking the same compute bill.

Fast, cheap open models such as MiniMax M3.1 Flash are exactly the kind of software that benefits from this hardware push. For more updates like this, see our latest AI news.

Conclusion

Tenstorrent’s $1.5 billion raise is one of the largest bets yet on an open alternative to Nvidia’s AI chips. The money is aimed at getting Galaxy servers into more data centers and growing the licensing business that already counts Samsung and LG as customers. Big investors are clearly buying into Jim Keller’s idea of one architecture sold at every size. The next test is whether real customers adopt the hardware at scale, not just whether investors believe they will.
