Jim Keller's AI chip startup just gave its suitors an answer — in funding, not a sale. Tenstorrent said Monday it has raised $1.5 billion in a late-stage funding round that values the Santa Clara company at $6.2 billion post-money, more than doubling its valuation from December 2024. The announcement lands days after reports that Intel and Qualcomm were in separate acquisition talks that could value the company as high as $10 billion.

The Series E round was led by Trace Capital and Innovation X, with Cathie Wood's ARK Invest, Sandisk, Morgan Stanley, T. Rowe Price and Tether Investments also backing the deal. Tenstorrent said the money will go toward scaling production of its Galaxy servers — racks that combine dozens of its AI chips to power chatbots, coding assistants and video generators.

A RISC-V bet against the GPU stack

Tenstorrent's pitch is an open one, literally. The company designs its AI chips and software on RISC-V, the open-source chip architecture that lets companies build processors without paying license fees to Arm or carrying the legacy weight of x86. For AI training and inference customers, the appeal is the same one driving the whole challenger-chip wave: more control over cost and power draw than Nvidia's GPU-centric stack typically offers.

Keller is the other half of the story. The Tenstorrent CEO previously led Tesla's effort to build a self-driving chip and held key chip design roles at Apple and AMD, where he led the Zen architecture that turned AMD's fortunes around. It is the kind of resume that makes a multibillion-dollar valuation for a startup still far from Nvidia's scale sound less absurd than it looks on paper.

Courted, bid on — and now bankrolled

The raise is the latest twist in a bidding war that has made Tenstorrent one of the most coveted assets in AI silicon. Earlier reports had Intel and Qualcomm pursuing separate acquisitions, with figures ranging from $5 billion in Bloomberg's earlier reporting to $8–10 billion in later reports from The Information, confirmed by Reuters. Intel never found a credible answer to Nvidia in AI accelerators; Qualcomm has almost no data-center AI presence. Both were said to be talking.

Tenstorrent, meanwhile, was reported to be running acquisition talks and a fresh funding round at the same time — the standard leverage playbook. Its last round, in December 2024, raised more than $693 million at a $2 billion pre-money valuation, led by Samsung Securities and AFW Partners. The new $6.2 billion valuation effectively sets the floor: any acquirer now has to top what private investors just paid.

What comes next

What the $1.5 billion buys is time and scale. Tenstorrent says the funding will expand Galaxy server production — the physical proof that its RISC-V architecture works beyond benchmarks, in the chatbots and coding assistants enterprises actually run. The company reached general availability with its Galaxy Blackhole systems earlier this year, and scaling shipments is the difference between being an attractive target and an independent competitor.

For the broader AI chip market, the message is that money is still flowing freely at the top end. Just days after the IMF flagged a $650 billion "circular" AI financing loop as a global market-shock risk, Tenstorrent's raise shows investors are still writing nine-figure checks for the silicon layer underpinning it all. Whether the company eventually sells or stays independent, the acquisition bidding told one story; today's raise told another: Tenstorrent doesn't need to be rescued. It just got richer.
