Britain's most celebrated AI chip startup raised $750M and was sold to SoftBank at a valuation far below its $2.8B peak as NVIDIA's dominance proved unassailable.
Evaluating only Graphcore’s profile at its peak — without knowing the outcome — the model ranked Competition as the #1 likely cause. That’s exactly how it died.

Documented cause
Graphcore was founded in Bristol in 2016 by Nigel Toon and Simon Knowles, developing a new processor architecture — the Intelligence Processing Unit (IPU) — specifically designed for machine learning workloads. The company raised approximately $750M from investors including Microsoft, Sequoia, and BMW iVentures, and reached a $2.8 billion valuation in 2021. Graphcore's IPU showed impressive benchmarks on specific research workloads but struggled with software ecosystem and developer adoption compared to NVIDIA's CUDA. As NVIDIA's H100 GPUs became the undisputed standard for AI training post-ChatGPT, Graphcore's differentiation eroded. In 2024, SoftBank acquired Graphcore for an amount widely understood to be a significant write-down from its peak valuation.
Lesson
“In chip design, hardware performance benchmarks are necessary but not sufficient — developer tooling, frameworks, and ecosystem lock-in determine who wins.”
