Tenstorrent, a 10-year-old AI chip startup, has raised $1.5 billion at a $6.2 billion valuation, more than doubling its worth from $2.6 billion in late 2024. The round was led by Trace Capital, founded by Quiet Capital co-founder Ben Mahdavi, and Innovation X, with participation from Cadence Ventures, Eclipse, Fidelity, SanDisk and T. Rowe Price.
The funding comes after reported acquisition interest from Intel and Qualcomm earlier this year at valuations up to $5 billion. Tenstorrent chose independence and the higher valuation after demonstrating its Galaxy servers could run DeepSeek models efficiently.
CEO Jim Keller, a veteran microprocessor designer, said the capital will scale chips optimized for inference—serving open-weight AI models and video generation. That focus matters: inference is where deployed models generate revenue for cloud providers and enterprises, not training, where Nvidia's GPUs still dominate.
Tenstorrent competes in a crowded space. Etched, another AI chip startup, reportedly fielded investment offers valuing it above $40 billion this month. But Tenstorrent's strategy is narrower—inference acceleration rather than general-purpose AI compute—which could be either a moat or a liability depending on whether the market fragments or consolidates around Nvidia's platform.
The capital enables product development and manufacturing scale. By staying independent, Tenstorrent retains its product roadmap—a valuable asset in a market where architectural choices lock in software ecosystems and customer switching costs run high.
