Tenstorrent raises $1.5B at $6.2B valuation, rejects buyout offers

AI chip startup Tenstorrent has raised $1. 5 billion in a Series E round, lifting its valuation to $6. 2 billion. The funding, led by Trace Capital and Innovation X, includes participation from ARK Invest, Fidelity, T. Rowe Price, and strategic backers like Sandisk and Cadence Ventures. The company plans to use the capital to expand manufacturing, grow its workforce, and advance its Galaxy servers, which began shipping earlier this year.

The round comes after Tenstorrent reportedly held acquisition talks with Intel and Qualcomm earlier in 2026. According to Bloomberg, the company chose to remain independent following a technical milestone in May, when its Galaxy servers demonstrated the ability to run high-performance AI models from DeepSeek. The move reflects Tenstorrent’s belief in its open, scalable architecture as a viable alternative to Nvidia’s leadership in AI hardware.

At the heart of Tenstorrent’s approach are its RISC-V Blackhole processors, which integrate Tensix AI cores to deliver 23 petaflops of FP8 compute performance in its Galaxy servers. The company positions itself as a full-stack provider, offering not just chips but integrated systems and custom server designs. CEO Jim Keller, known for his work at Apple, AMD, Tesla, and Intel, has framed the company’s vision as one where compute is accessible and adaptable.

The $6. 2 billion valuation represents a significant jump from Tenstorrent’s previous funding round in late 2024, when it raised hundreds of millions from investors including major firms and individual backers. The latest round’s size and investor interest suggest continued appetite for alternatives to Nvidia, despite broader market scrutiny of AI hardware startups. Tenstorrent’s strategy targets customers seeking more flexible or cost-effective solutions than those offered by dominant players.

The decision to stay independent highlights a key question in the AI chip market: whether startups can compete with incumbents without being acquired. Earlier reports had suggested potential deals could have reached substantial figures, though no formal offers materialized.

The timing of the funding round aligns with Tenstorrent’s push into integrated AI systems. Its Galaxy servers, which began shipping in April, mark a shift from standalone chips to a more comprehensive hardware offering. This evolution reflects a broader industry trend toward full-stack solutions, where hardware and software are increasingly bundled to meet specific AI workloads. Tenstorrent’s use of RISC-V, an open instruction set architecture, also aligns with a growing demand for customizable chip designs.

What lies ahead will test Tenstorrent’s ability to scale. For now, the $1. 5 billion raise and $6. 2 billion valuation signal investor confidence in its approach—though the path to challenging Nvidia remains uncertain.
