MatX Raises $500M Series B

Our portfolio company MatX has raised a $500 million Series B, led by Jane Street and Situational Awareness LP. The funding will go toward wrapping up development and scaling manufacturing of the MatX One, a dedicated LLM inference chip. Unlike general-purpose GPUs, the MatX One is built from scratch for large language model workloads, using a novel architecture that prioritizes memory bandwidth efficiency to deliver faster, cheaper inference at scale.

We backed MatX early because we believed the next wave of AI infrastructure would demand purpose-built silicon. With tapeout on the horizon, that conviction is playing out.
