Tenstorrent Is Worth $6.2 Billion Now. Toronto Kept the Engineers, California Got the Headquarters.
Jim Keller's RISC-V chipmaker raised $1.5 billion to take on GPU dominance. Its largest office is still in Toronto, and that raises an awkward question about who benefits from Canadian AI hardware talent.

The biggest bet investors have ever placed on a Toronto-born chip company just landed, and it came with a California return address. The Tenstorrent Series E, announced October 19, raised $1.5 billion at a $6.2 billion post-money valuation, according to the company's announcement.
That is more than double the roughly $2.6 billion the company was worth after its Series D in December 2024, as BetaKit reported. Trace Capital and Innovation X led the round, joined by Fidelity, Morgan Stanley, T. Rowe Price, ARK Invest, Sandisk, Tether Investments, Virtu Financial and XTX Markets, among others.
What Did the Tenstorrent Series E Actually Buy?
Scale, mostly. Tenstorrent says the money will put its Galaxy servers into deployment at volume, serve open-weight language and video models, and advance the AI and CPU designs it licenses to companies building their own silicon. Samsung and LG already license its TT-Ascalon RISC-V processor and Tensix AI cores, per the release.
Openness is the pitch. The company builds on RISC-V, an open instruction set that carries no license fees, and its Blackhole cards pair those cores with GDDR6 memory instead of the scarce high-bandwidth memory that top-end GPUs depend on, according to SiliconANGLE. "We built one architecture and sell it at every size," chief executive Jim Keller said in the announcement. "The future of compute is open, scalable, and owned by the people building on it."
Much of the money was spoken for before the press release. A Form D filed with the SEC in September showed about $1.29 billion already sold to 134 investors, with sales starting August 26, according to Revenue Memo's reading of the filing.
Why Does Jim Keller Matter So Much to Investors?
Because his résumé is a large part of what they are buying. Keller worked on Apple's A4 and A5, AMD's Zen and Tesla's self-driving chip, as Unite.AI summarized. He joined Tenstorrent as president and chief technology officer and became CEO in January 2023, when founder Ljubisa Bajic stepped into the technology role, BetaKit reported at the time.
His name also makes the company a target. In June, The Information reported that Qualcomm was in talks to buy Tenstorrent for $8 billion to $10 billion, a report Reuters picked up and both companies declined to comment on, according to Igor's Lab. BetaKit noted reports of Intel interest as well, and said Keller had described an IPO as the goal. A spokesperson would not discuss any of it this week. Whatever the endgame, raising $1.5 billion on its own terms gives Tenstorrent a much stronger hand at any table it sits down at.
Where Is Tenstorrent Headquartered Now?
Santa Clara, California. Bajic, Ivan Hamer and Milos Trajkovic, all former AMD engineers, founded the company in Toronto in 2016. It moved its headquarters south in November 2023 and wound up its federal Canadian corporation a month later, swapping shares into a Delaware parent, according to The Logic.
The company gave BetaKit two reasons in 2024. A major investor wanted a bigger stake than it was allowed to hold in a company based outside the United States, and US incorporation is the usual runway for a listing on the Nasdaq or the NYSE, as BetaKit reported.
Toronto has not been abandoned. It is still the company's largest office, with about 200 of roughly 1,000 employees, and some parts are still made at Vexos Canada's site in Markham, per BetaKit. Export Development Canada, Toronto's Georgian and the Healthcare of Ontario Pension Plan are existing backers, and unnamed Canadian investors joined this round too.
What Does Tenstorrent's Raise Mean for Canadian AI Hardware?
It fits a pattern Canada should find uncomfortable. When AMD bought Taalas, Bajic's second Toronto chip startup, in August, The Logic's Murad Hemmadi wrote that "Toronto has now lost all three of its high-profile chip startups." Tenstorrent redomiciled, Untether AI shut down in June 2025 after AMD hired away its engineers, and Taalas sold outright, The Logic reported.
The engineers mostly stayed. Ownership, headquarters and the bulk of the upside did not.
Ottawa's answer so far has been to buy compute rather than grow the companies that design it. Budget 2024 set aside $2 billion for the Canadian Sovereign AI Compute Strategy, and the first investment announced under it backed a Cohere facility built around Nvidia GPUs, BetaKit reported in December 2024. Getting researchers capacity quickly is a fair goal. It also means sovereign compute dollars flow to the very supplier Tenstorrent is trying to unseat.
Can an Open Chip Company Really Challenge Nvidia?
Not by itself, and not soon. Tenstorrent's wager is narrower and more plausible than toppling a giant. It is betting that a meaningful slice of buyers, from Korean electronics conglomerates to national compute programs, would rather license, modify and own their hardware than rent someone else's roadmap, and its Series E announcement pitches directly to sovereign infrastructure players.
That is where Canada has a choice to make. A company with its biggest engineering office in Toronto, a parts supplier in Markham and Canadian pension and export-credit money on its cap table is about as close to a homegrown AI chip champion as the country currently has, even if its mail goes to California.
If sovereignty is going to mean more than where the servers sit, it would help for Canadian compute programs to treat Canadian-designed silicon as a real option rather than a footnote. Investors just put a $6.2 billion price on the idea that open hardware has buyers. Ottawa has not yet said whether it intends to be one.
