Tenstorrent Doubles Valuation to $6.2B in $1.5B Series E

Tenstorrent has raised $1.5 billion in a Series E round that values the chip startup at $6.2 billion — more than double its $2.6 billion valuation in late 2024. Houston-based Trace Capital and Maryland's Innovation X Advisors co-led the round, the Santa Clara, Calif.-based company said.

The buyer list reads like a cross-section of finance and technology. Participants included Fidelity Management & Research Company, T. Rowe Price, Morgan Stanley, ARK Invest, Eclipse, Cadence Ventures, Sandisk, Tether Investments, XTX Markets, Virtu Financial, Maverick Silicon, Agostinelli Group, Brett Barna, Troluce Capital, and Florida's Protagonist, the firm confirmed.

Who is behind Tenstorrent?

Former AMD engineers Milos Trajkovic, Ljubisa Bajic and Ivan Hamer founded the company in 2016, originally in Canada. Early investor Jim Keller now runs it — a chip architect whose résumé spans Intel, AMD, Apple and Tesla. At each of those companies, Keller drove major chip programs: AMD's Zen, Apple's A4 and A5 processors, and Tesla's custom self-driving silicon.

That track record attracted acquisition interest. Intel and Qualcomm reportedly bid as much as $5 billion for the startup — a figure below the strategic premium a founder might expect for a company now worth $6.2 billion on paper, though reportedly offered before this round priced the business. Keller told Bloomberg the company prefers its chances as an independent player as it scales chips tailored for open-weight AI models.

What does the technology actually do?

Tenstorrent's Galaxy servers have demonstrated the ability to run Chinese company DeepSeek's open-source large language models, the company said. It sells AI compute at every level of the stack: a single card or workstation, full racks, superclusters, and custom IP.

The pitch to developers rests on openness. With an open-source software stack, developers can run frontier models locally and enterprises can deploy models on-premises at industry-leading latency and throughput, according to the company. That claim is Tenstorrent's own; no independent benchmark results appear in the announcement.

Keller framed the strategy in a statement: "We built one architecture and sell it at every size. The future of compute is open, scalable, and owned by the people building on it." One architecture, scaled across form factors — a clean story, though it puts Tenstorrent in direct competition with incumbents whose sales channels dwarf its own.

Where will the money go?

The company said the new capital will fund deployment of Galaxy servers at scale, serving open-weight models across LLMs and video generation. It will also back further development of the AI and CPU IP that Tenstorrent licenses to customers designing their own silicon.

Backer commentary leaned on that dual capability. "Few companies design the chip and the software that runs on it. Tenstorrent does both, and its video generation results beat industry benchmarks ahead of our expectations," said George Bousis, co-founder and managing partner at Protagonist, which is headquartered in Bay Harbor Islands near Miami. "We are excited to double down in the Series E to back Jim and the team through this next phase of growth."

The valuation math is worth pausing on. At $6.2 billion, investors are paying roughly 2.4 times the late-2024 price in about a year — a jump that assumes the open-weight AI market keeps expanding fast enough to fill those Galaxy server racks. Bousis's benchmark claim, notably, cites no specific figures.

What the announcement does not say is equally telling. Tenstorrent disclosed no revenue figures, no customer counts, and no timeline for the server deployments. A $1.5 billion raise buys time and capacity; it does not, by itself, buy the enterprise wins that would justify the doubling.

The bet, in plain terms: that AI buyers will want open, on-premises alternatives to the closed stacks now dominating the market — and that Keller's record translates into share.
