Tenstorrent, a chip designer based in Santa Clara, California, raised US$1.5 billion in a Series E funding round on 19 October 2026 at a US$6.2 billion post-money valuation. The company builds processors for artificial intelligence (AI) and plans to use the money to start volume manufacturing.
For US readers, the round puts big American asset managers behind a challenger in AI hardware, a market where data-centre demand keeps growing. Investors include Fidelity, Morgan Stanley, T. Rowe Price and ARK Invest.
Who Invested
Trace Capital and Innovation X led the round, according to Tenstorrent’s announcement. Other named participants include Agostinelli Group, Cadence Ventures, Eclipse, Maverick Silicon, Protagonist, Sandisk, Tether Investments, Troluce Capital, Virtu Financial and XTX Markets.
The company published only the date of the announcement and no time. It did not disclose how much each investor contributed.
What Tenstorrent Builds
Tenstorrent designs AI processors on RISC-V, an open standard for chip design that companies can use without paying licence fees to a single owner. Its Galaxy servers link many of its processors, and one configuration uses 32 Blackhole chips with about 23 petaflops of AI computing power.
The company announced general availability of Galaxy Blackhole at scale on 28 April 2026. Jim Keller, its chief executive, previously worked on chip designs at Apple, AMD and Tesla.
What the Money Is For
Tenstorrent said the funds will pay for volume manufacturing, global commercial expansion and large-scale deployment of Galaxy servers. It also named next-generation hardware, AI and CPU design work, and hiring.
The company said the round will support open-weight AI models as well, including large language models and video generation. Open-weight models are AI systems whose trained parameters are published so others can run them.
A Valuation More Than Doubled
Tenstorrent’s previous Series D round in December 2024 raised more than US$693 million at a US$2 billion pre-money valuation. The new US$6.2 billion valuation is more than double that level.
The company is headquartered in Santa Clara, and it also has offices in Austin, Toronto, Belgrade, Tokyo and Bangalore. Several outlets describe it as a Canadian-founded company that started in Toronto in 2016.
What It Means for You
Investors who follow AI hardware should note that Tenstorrent’s funding comes from large public-market managers as well as venture firms. That mix suggests investors still see room for new chip designs beyond the largest suppliers.
Tenstorrent remains a private company, so ordinary investors cannot buy its shares on an exchange. Exposure comes mainly through the funds that hold stakes.
What Is Not Known
Tenstorrent has not published how much it raised in new shares versus sales by existing holders. It has also not disclosed ownership percentages or the price per share.
The announcement does not give customer numbers or shipment volumes for Galaxy servers. Without them, it is hard to judge how quickly the new money will turn into revenue.
