Positron Raises $230M Series B to Compete with Nvidia’s AI Chips: POSI

[Para 1: The Lead] Positron, a semiconductor startup, secures $230 million in Series B funding to accelerate deployment of high-speed memory chips for AI workloads. The capital, announced today, February 4, 2026, will be used to compete with Nvidia in the AI chip market. Investors include Qatar Investment Authority (QIA). [Para 2-3: Supporting details & Context] Positron’s Series B funding, disclosed today, marks a significant step as hyperscalers and AI firms seek alternatives to Nvidia. The startup, based in Reno, aims to offer performance comparable to Nvidia’s H100 GPUs at a fraction of the power consumption. Positron’s focus on inference, rather than training large language models, aligns with growing demand for inference hardware. The company’s first-generation chip, Atlas, manufactured in Arizona, is designed to match Nvidia’s performance while significantly reducing power usage. Beyond memory capabilities, Positron’s chips excel in high-frequency and video-processing workloads, positioning the company as a competitive player in the AI chip market.
