AI 芯片初创 Positron 完成 8.75 亿美元 C 轮融资，估值达 50 亿美元
AI 芯片初创公司 Positron 于 2026 年 9 月 10 日宣布完成 8.75 亿美元（约 62.5 亿元人民币）C 轮融资，投后估值达 50 亿美元，募资用于将新一代推理芯片（inference silicon）推向市场。
本轮融资使 Positron 成为炙手可热的 AI 算力新势力。公司此前已先后完成 5000 万美元以上的 A 轮，以及估值超 10 亿美元的 2.3 亿美元 B 轮。
Positron 主打高能效的 AI 推理加速器，被视为英伟达（NVIDIA）GPU 的替代方案之一，目标是大模型推理这一增长最快的环节提供更高性价比的算力。
公司称，随着大模型训练趋缓、推理需求爆发，市场对非 GPU 架构的 AI 芯片需求急剧上升；Positron 的加速器以更优的能效比切入数据中心与云服务商市场。
此次估值跃升（仅 B 轮后不久即从 10 亿+ 跃升至 50 亿美元）反映出资本对「后 GPU 时代」算力格局的强烈下注，也凸显 AI 芯片赛道在 2026 年的持续高热。

AI chip startup Positron completes $875 million Series C funding, reaching $5 billion valuation
AI chip startup Positron announced on September 10, 2026, the completion of an $875 million (approximately 6.25 billion RMB) Series C financing round, bringing its post-investment valuation to $5 billion. The funds will be used to launch a new generation of inference chips into the market.
This round of financing has elevated Positron to a prominent position in the AI computing power sector. Previously, the company successfully completed a Series A round of over $50 million and a $230 million Series B round with a valuation exceeding $1 billion.
Positron specializes in high-efficiency AI inference accelerators and is considered a potential alternative to NVIDIA GPUs. The company aims to provide a more cost-effective computing solution for the rapidly growing large-model inference market.
The company reports that as large model training slows and inference demands surge, there is a significant increase in the market need for non-GPU architecture AI chips. Positron's accelerators are expected to gain a foothold in the data center and cloud services markets with their superior energy efficiency ratio.
The rapid increase in valuation (from over $1 billion during Series B to $5 billion) demonstrates the strong confidence of investors in the future trajectory of AI computing power and the enduring heat of the AI chip market in 2026.
