NVIDIA投资了大量AI模型公司锁定客户,并洞见下一代计算能力的走势;其次,NVIDIA在其自身强大的网络能力之外,依靠对下一代网络芯片的投资,将其GPU的高效协同算力扩展到更高的速度和更广的范围;此外,NVIDIA还在投资上对具身智能做了长远布局。分析其投资行为,对我们的投资、创业具有深刻意义。 投资 AI 模型和云平台 构建以 GPU CUDA 为核心的AI生态 NVIDIA在AI行业的核心优势既有GPU,更依靠CUDA锁定了全球开发者生态。随着大语言模型的突破,NVIDIA首先投资了几乎所有处于前沿的AI模型公司,包括语言模型和多模态模型。 模型公司 OpenAI NVIDIA在2024年10月参与了OpenAI高达66亿美元的一轮融资,在此次融资中投入1亿美元;在2025年9月,英伟达和OpenAI宣布计划共同部署高达10吉瓦(gigawatts)的英伟达AI算力系统,英伟达承诺将投资高达1000亿美元用于此项合作。 作为AI行业的领头羊,OpenAI不仅拥有Sota级别的语言模型和视觉模型,还打造了AI时代“入口”级别的超级应用ChatGPT。 xAI NVIDIA此前已参与xAI的几轮融资,例如2024年的两次60亿美元融资(B轮和C轮),在今年9月,它又参与了xAI总额高达200亿美元的融资轮次,投资金额达20亿美元。 黄仁勋表示:“凡是Elon Musk参与的公司,我都想投资”。除了投资外,NVIDIA与xAI有长期合作关系,包括提供H100 GPU用于xAI的超级计算机Colossus。 作为一家成立于2023年7月的公司,xAI在短短两年内,就推出Grok4这款能够达到Sota水平的模型,成为了行业中的头部公司。 Mistral AI NVIDIA在2024年和2025年分别投资了Mistral AI的B轮和C轮融资,获得17亿欧元的C轮融资后,Mistral AI的估值达到117亿欧元。 在2025年6月,黄仁勋宣布与Mistral AI合作,在法国建立AI计算基础设施,部署最新一代的NVIDIA Grace Blackwell系统,初期计划部署18000个Blackwell GPU。 Mistral AI是欧洲地区最强大的AI模型开发商,旗下Mistral Large等模型接近Sota级别性能,开源模型具有超过100万的下载量,其ToC应用也较受欢迎。 Runway 2025年4月,英伟达参与Runway金额为3.08亿美元的D轮融资,Runway投后估值超30亿美元。Runway是视觉多模态模型的开拓者之一,目前有高性能的视觉模型及Runway Studios等面向专业领域的视觉设计产品。 除了以上投资外,NVIDIA在AI模型核心领域的投资还包括Cohere(主要面向企业),Sakana AI(主要研究小模型),以及Reflection AI、Thinking Machines Lab、Imbue等更偏向探索和创新的公司。 它投资这些前沿模型公司的核心逻辑是,前沿模型的数量越多,性能越强,消费者和客户的选择多,整个AI应用生态的基石就越稳固,NVIDIA锁定了两类关键角色,即模型公司和搭建AI算力平台的合作方。 AI云平台 除了前沿模型公司,NVIDIA投资版图中另一个重要的领域是具有先进技术的AI云平台以及数据中心运营商,为更下游的AI应用层公司提供算力,进一步扩大NVIDIA生态系统的规模和范围。 这其中最典型的公司是CoreWeave,Together AI和Nscale。 CoreWeave NVIDIA在2023年参投了AI云平台CoreWeave的B轮融资,注资1亿美元,在CoreWeave于2025年IPO时又参与了认购,目前NVIDIA持有CoreWeave约7%的股份。上市后,CoreWeave的市值已经达到约700亿美元,2025年预计营收为50.08亿美元。它拥有25万个NVIDIA GPU,既是NVIDIA的被投企业,也是大客户之一。 Together AI Together AI同样是一家AI云平台,它在2025年获得NVIDIA参投的3.05亿美元B轮融资,估值33亿美元。 与CoreWeave不同的是,它更偏向技术派,有自己的核心技术FlashAttention-3和Flash-Decoding,分别对应快速推理和长序列推理场景,给企业客户和开发者们带来了差异化的体验,也拓展了NVIDIA GPU在推理方面的技术边界。 Nscale Nscale的主要业务是高性能数据中心、GPU集群的建设,2025年9月获得NVIDIA参投的11亿美元B轮融资(NVIDIA投资6.83亿美元)。 它的数据中心配备大规模NVIDIA GPU集群,并集成高速网络和自研软件栈,支持高效处理千亿参数级大语言模型(LLM)的训练任务。它的主要客户包括OpenAI(共同建设星际之门项目)和微软。 NVIDIA还参投了Crusoe、Lambda和Firmus Technologies等AI云平台和数据中心建设商,这些公司的估值都达到了数十亿美元级别。 创新类芯片公司 NVIDIA依赖芯片的scale up(单块板上叠加芯片数量)和scale out(不同服务器间高速互联)构筑了基于GPU的强大算力,依靠其强大的网络通信能力提供高效率的集群计算能力,当然也彻底吃掉了传统服务器厂商的市场。 不仅如此,NVIDIA还投资了网络芯片公司继续强化其智算中心的布局,包括Ayar Labs和Enfabrica。这类网络芯片的主要作用是在NVIDIA的现有网络“射程”外扩展,在算力芯片之间进行高速和大带宽的通信,以提高更大范围内算力集群的网络吞吐能力。 Ayar Labs Ayar Labs的技术核心是硅光子学与芯片封装结合的光互连解决方案,它的光学 I/O Chiplet,可以实现单芯片支持8.192Tbps 双向带宽(16个模块×512 Gbps/模块),带宽密度达896Gbps/mm,端到端延迟<25ns(含光纤传输)。NVIDIA参投了它2023年的C轮融资和2024年的D轮融资。 Enfabrica Enfabrica的技术核心是加速计算结构(ACF)与弹性内存架构,它的ACF-S超级网卡芯片整合PCIe/CXL交换与以太网RDMA功能,支持10万级GPU互联,ACF-S 芯片的CXL内存池解决方案,通过共享DDR5内存缓解GPU高带宽内存(HBM)瓶颈。 NVIDIA对这家公司十分青睐,不仅在2023年和2024年参投了它的B轮和C轮融资,而且在2025年以9亿美元的价格收购Enfabrica核心团队及技术授权,Enfabrica创始人Rochan Sankar也入职NVIDIA。 综上所述,NVIDIA通过投资AI模型公司,AI云平台和围绕GPU的创新芯片,构建和巩固了自身在AI领域的生态,也通过这些投资版图,让自己事实上成为AI行业中最大,最坚实的基础。 投资Physical AI 为第三次AI浪潮做准备 什么是NVIDIA眼中AI最有前途的发展方向,从它真金白银投资的领域来看,是Physical AI(物理AI)。 当然,NVIDIA也投资了不少AI领域的垂直应用,例如Perplexity(AI搜索引擎),Hippocratic AI(AI医疗),Poolside(AI编程)和Kore.ai(企业AI)。但是对于Physical AI,NVIDIA不仅进行了投资,还自己下场做。 它有自己的Cosmos世界基础模型,开放物理AI数据集,Omniverse物理AI操作系统,以及DRIVE Thor自动驾驶芯片和NVIDIA Jetson边缘计算平台。 黄仁勋认为生成式AI(Generative AI)是AI的第二波浪潮,而下一波浪潮就是Physical AI,因为它超越了数字世界,让AI能够与现实物理世界进行互动,理解物理定律、摩擦力、惯性以及因果关系等。 当然,NVIDIA重点投资了一批Physical AI相关的公司,例如Figure AI(人形机器人)、Dyna Robotics(商业机器人)、Serve Robotics(配送机器人)、Wayve(自动驾驶)、Nuro(自动驾驶)、Bright Machines(智能工厂)等。 Figure AI 人形机器人公司Figure获得NVIDIA参投的10亿美元C轮融资。它是一家全栈的具身智能公司,既有人形机器人本体(最近发布了Figure 03),又有自己的机器人模型和制造能力,是机器人创业公司中能力最全面的超级独角兽。 Wayve Wayve在2024年获得NVIDIA参投的10.5亿美元C轮融资,在2025年下半年,有消息称NVIDIA将对Wayve追加金额为5亿美元的战略投资。 Wayve的核心产品是一套基于端到端神经网络的自动驾驶系统,它无需依赖高精度地图,仅利用数据来教导车辆如何驾驶。这种数据驱动的学习方法适用于从“目视辅助驾驶”到“脱手全自动驾驶”(L4 级)的全系列功能。 Bright Machines Bright Machines在2024年6月获得NVIDIA参投的1.26亿美元C轮融资。Bright Machines为制造业公司提供全栈自动化解决方案,彻底改变了现有的生产模式。这个方案能够为产品从设计、制造到拆卸的整个生命周期提供灵活的自动化支持。 AI 模型是现在 Physical AI是未来 遍观NVIDIA的近100个AI投资项目,可以看到它们仍然带有很强的企业战略投资的色彩,尤其是对于模型和AI云平台的投资,这些被投企业普遍都同时会是NVIDIA GPU的买家。NVIDIA对这些企业的投资,是为了构建以GPU为核心的生态,这个生态是为了巩固它在AI行业的地位。 而投资Physical AI领域的公司,也是为了建立生态,但是这个生态属于未来,是为了建立NVIDIA之后的新增长极。 为什么Physical AI或者AI原生硬件是AI的下一波浪潮?正如黄仁勋所说,它超越了数字世界,让AI能够与现实物理世界进行互动,为AI未来重塑物理世界打下了基础。
