In May, Tenstorrent had a choice most chip founders only dream about. According to Bloomberg, the company held takeover talks with giants including Intel and Qualcomm. Jim Keller, the engineer behind some of the most famous processors of the last 25 years, could have sold. He decided to raise money instead.
On Monday, October 19, 2026, that bet got a price tag. Tenstorrent announced a $1.5 billion Series E at a $6.2 billion post-money valuation, more than double the $2.6 billion it was worth after its last round in December 2024.

Tenstorrent raised $1.5 billion at a $6.2 billion valuation, led by Trace Capital and Innovation X, after choosing independence over a sale.
What Happened
The round was jointly led by Trace Capital and Innovation X, according to Tenstorrent's Series E announcement as reported by The Next Web. New and existing backers joined them, including Fidelity, T. Rowe Price, Morgan Stanley, ARK Invest, Protagonist, Eclipse, Maverick Silicon, Cadence Ventures, Sandisk, Tether Investments, Virtu Financial and XTX Markets.
That investor list says a lot. Mutual fund giants like Fidelity and T. Rowe Price often show up when a company is getting closer to public markets. Trading firms like Virtu and XTX Markets are not just investors but heavy users of fast, private AI compute. And Sandisk is a memory company with an obvious interest in where AI hardware goes next.
"The future of compute is open, scalable and owned by the people building on it," Keller said, as quoted by SiliconANGLE.
How Tenstorrent Got Here
Tenstorrent started in Toronto in 2016 as an AI chip design startup. Keller joined in 2020 and later became chief executive. His name carries real weight in the industry: the company credits him as the architect of Apple's A4 and A5 chips, AMD's Zen architecture and Tesla's Full Self-Driving chip.
Under Keller, Tenstorrent made two big strategic choices.
First, it built on RISC-V, the open instruction set that anyone can use without paying licensing fees to a single owner. Its Tensix Neo AI accelerators and Ascalon CPUs are both RISC-V designs.
Second, it open-sourced its software. Nvidia's real moat is not only its chips but CUDA, the software layer developers have relied on for nearly two decades. Tenstorrent's answer is an open stack: TT-Forge, a compiler that connects frameworks like PyTorch to its hardware, and TT-Metalium, a kit for low-level tuning and custom kernels.
The company also moved from selling only chip designs to selling complete systems. Today its range runs from Blackhole PCIe cards and the TT-QuietBox desktop workstation up to Galaxy servers, which can be linked into large clusters. SiliconANGLE describes Galaxy as its best-selling product. "We've built one architecture and we sell it at every size," Keller said.
It still licenses its AI and CPU designs to companies building their own chips. The Next Web names Samsung and LG among those licensees.
The Numbers
| Date | Milestone | Detail |
|---|---|---|
| 2016 | Founded in Toronto | AI chip design startup |
| 2020 | Jim Keller joins | Later becomes CEO |
| Dec 2024 | Series D | About $693M at a $2.6B valuation, led by Samsung Securities and AFW Partners, with Bezos Expeditions, LG and Hyundai |
| May 2026 | Takeover talks reported | Intel and Qualcomm among interested parties (Bloomberg) |
| May 2026 | DeepSeek demo | Galaxy servers run high-performance DeepSeek models |
| Oct 19, 2026 | Series E | $1.5B at a $6.2B post-money valuation |
A few more figures help explain the scale:
- Employees: about 1,150, according to Bloomberg via The Next Web.
- Offices: Santa Clara, Austin, Toronto, Belgrade, Tokyo and Bangalore.
- Valuation jump: roughly 2.4 times in under two years.
- Previous round makeup: BetaKit reported that the 2024 Series D included over $593 million in new equity plus a $100 million convertible note that turned into shares.
Tenstorrent has not disclosed revenue for 2026, so treat any revenue figures you see elsewhere as unconfirmed.
Why It Matters
The AI chip market is dominated by Nvidia, with AMD and Broadcom as the other big names. Plenty of startups have tried to break in. Many have struggled, because building a chip is hard, but convincing developers to leave CUDA is harder.
Tenstorrent's pitch is different in three ways. It sells hardware at every size, so a trading firm can buy a few servers while a cloud provider buys racks. It competes on price, and Keller told Bloomberg it can take orders that may be too small for bigger rivals. And it is open: open instruction set, open software, licensable designs.
Customers are starting to show up. SiliconANGLE reports that Virtu Financial runs AI trading agents on Galaxy servers on its own premises, and Equinix offers Galaxy servers to businesses through its data centres.
"Nvidia is not the only option anymore," Holger Mueller of Constellation Research told SiliconANGLE. For companies paying high prices and waiting in long queues for GPUs, a credible second option matters.
Lessons for Founders
1. A buyout offer is leverage, not destiny. Tenstorrent turned interest from Intel and Qualcomm into proof of value, then raised at more than double its last price. When big players want to buy you, investors notice.
2. Proof beats promises. Keller called the May demo of DeepSeek models on Galaxy servers a turning point. One public, convincing demonstration did more than any pitch deck.
3. Pick a fight you can win. Tenstorrent is not trying to beat Nvidia at everything. It goes after price-sensitive buyers, smaller orders and teams that want control over their stack.
4. Open can be a business model. Giving away software and building on an open standard lowers the cost for customers to try you. The money comes from hardware and licensing.
5. Your investor list is a signal. Customers like Virtu investing alongside large public-market funds tells the market the product works.

What to Watch
- Galaxy deployments: the money is meant to ramp up server production worldwide. Watch for new named cloud and enterprise customers.
- Software adoption: the open stack only wins if developers use it. Model support and community activity are the signals.
- An IPO path: with Fidelity, T. Rowe Price and Morgan Stanley in the round, public-market talk is likely. Nothing has been announced.
- RISC-V momentum: more licensees beyond Samsung and LG would strengthen the open-chip story.
