Tenstorrent has closed a $1.5 billion Series E at a $6.2 billion valuation, more than double its previous mark. The company is led by Jim Keller, the chip architect behind work at AMD, Apple and Tesla.
Tenstorrent's position is different from most AI chip startups. Rather than only selling accelerators, it licenses its RISC-V based designs, which lets customers build their own silicon instead of renting someone else's roadmap. That pitch has found buyers at a moment when the alternative is a queue for Nvidia parts and a price set by a single supplier.
The raise lands in a week of mixed signals for AI hardware. The Philadelphia Semiconductor Index has been falling, with memory names hit hardest, and Bernstein put only about 35% of the announced US data centre pipeline in the credible column. Capital is still arriving for anyone offering a way around the Nvidia bottleneck, even while the buildout those chips are meant to fill looks less certain than the announcements suggest.
