Tenstorrent raises $1.5 billion to challenge Nvidia: who they are and why investors care
AI chip startup Tenstorrent, led by legendary chip designer Jim Keller, has raised $1.5 billion at a $6.2 billion valuation. Here's what it makes, how it's different from Nvidia, and what the money is for.
Tenstorrent, an AI chip startup trying to take on Nvidia, has raised $1.5 billion in new funding at a value of $6.2 billion. That’s more than double what it was worth less than two years ago.
With AI companies desperate for chips and Nvidia dominating the market, investors are betting on alternatives. Here’s why Tenstorrent stands out.
The funding round
- Amount: $1.5 billion (Series E)
- Valuation: $6.2 billion, up from $2.6 billion after its $700 million Series D in December 2024
- Lead investors: Trace Capital and Innovation X
- Other investors: Fidelity, Morgan Stanley, ARK Invest, T. Rowe Price, Cadence Ventures, SanDisk, Tether Investments, Virtu Financial and XTX Markets
Who is behind Tenstorrent?
Tenstorrent is led by CEO Jim Keller, one of the most famous chip designers in the world. Over his career, he has worked on important chips at AMD, Apple, Tesla and Intel. When Keller backs a chip design, the industry pays attention.
What does Tenstorrent make?
Its main product right now is Galaxy, a line of AI servers for training large AI models and generating video. These servers are already used by customers such as trading firm Virtu Financial and data center company Equinix.
The RISC-V difference
Tenstorrent builds on RISC-V, an open chip design standard. Most chips use designs that companies must license and pay for (like Arm) or that are owned by one company (like Intel’s x86). RISC-V is free for anyone to use and change, which can lower costs and give customers more freedom.
Nvidia’s strength is a closed, all-in-one system. Tenstorrent is betting that many customers want something more open and affordable.
Why does this matter?
- Nvidia dominates AI chips, and its GPUs are expensive and often in short supply.
- AI companies and cloud providers want more choice and lower prices.
- More competition could help bring down the cost of running AI, which affects the price of AI tools everyone uses.
What will the money be used for?
Tenstorrent plans to use the funding to scale up mass production of Galaxy servers and grow its sales worldwide.
Can Tenstorrent really beat Nvidia?
Not soon. Nvidia’s lead comes not just from its chips but from CUDA, the software almost every AI developer uses. Any challenger must convince developers to switch. But even a small share of the huge AI chip market could make Tenstorrent very valuable, which is what investors are betting on.
