AI chip startup ,,Tenstorrent'' expands investment

AI chip startup Tenstorrent is close to securing $800 million in new financing, with Fidelity Management expected to lead the round. If finalized, this would value the company at roughly $3.2 billion, marking a significant rise from its $2.6B valuation in late 2024 and highlighting investor demand for credible alternatives to Nvidia, which currently dominates over 80% of the AI accelerator market. Founded in 2016 and now led by renowned chip architect Jim Keller, Tenstorrent focuses on developing high-performance AI processors built largely on the open RISC-V architecture, allowing for lower licensing costs and more customization. The company differentiates itself by avoiding Nvidia’s expensive HBM memory model, instead using standard DDR memory to reduce costs and improve accessibility for developers. Its product lines, including Grayskull and Wormhole, target both cloud training and edge inference, while the upcoming Quasar chip — manufactured by Samsung — shows the company’s willingness to mix architectures as needed. With more than $1.18B already raised, plus $150M in customer contracts (including Samsung and Hyundai), Tenstorrent has positioned itself as one of the most serious challengers in the AI chip market. The potential new funding would accelerate next-generation chip development, support global team expansion, and strengthen its IP licensing model. As the AI compute market races toward an estimated $83B by 2027, Tenstorrent aims to capitalize on growing demand for open, modular, and cost-efficient alternatives to Nvidia’s tightly integrated ecosystem. Though the company still faces manufacturing dependencies and revenue that trails far behind Nvidia, it has become a key player to watch in the rapidly evolving AI hardware landscape.
