Exclusive: Positron Raises $230M Series B to Take on Nvidia’s AI Chips

Semiconductor startup Positron announced a $230 million Series B round, led in part by Qatar Investment Authority. The capital will accelerate deployment of its high‑speed memory chips and the Atlas inference processor, which claims H100‑class performance at a third of the power consumption. Positron’s raise brings total funding to over $300 million as AI firms seek alternatives to Nvidia for inference workloads. The funding aligns with Qatar’s broader sovereign AI infrastructure strategy.
