Positron closed a $230 million Series B at a reported $1 billion valuation, co-led by Arena Private Wealth, Jump Trading, and Unless, with strategic capital from Qatar Investment Authority (QIA). Positron is focused on inference silicon rather than training, aligning with a market shift from building ever-larger foundation models to deploying them at scale. Its first-generation Atlas chip, manufactured in Arizona, is designed around high-speed memory throughput and is claimed to match Nvidia H100-class performance at under one-third the power for select inference workloads.
