Among them, Amazon invested $50 billion (approximately RMB 342.9 billion) in OpenAI. The first - batch investment is $15 billion (approximately RMB 102.9 billion), and after meeting specific conditions, it will invest an additional $35 billion (approximately RMB 240 billion) in the next few months. On February 26th, according to The Information citing sources familiar with the matter, the subsequent $35 billion investment from Amazon may depend on whether OpenAI reaches the milestones of general artificial intelligence or goes public.

The cooperation between OpenAI and Amazon also includes that OpenAI will use 2 gigawatts of Trainium AI chips through AWS; AWS will serve as the exclusive third - party cloud provider for OpenAI's enterprise - level platform, Frontier.

NVIDIA invested $30 billion. OpenAI's blog mentioned that they are expanding their long - term cooperation with NVIDIA, including using 3 gigawatts of dedicated inference computing power and providing 2 gigawatts of training computing power on the Vera Rubin system.

Its official blog mentioned that before this round of financing, OpenAI's pre - valuation reached $730 billion (approximately RMB 5 trillion), and the new valuation after the financing was not disclosed.

Altman thanked the three investors on the social platform X and also comforted Microsoft by the way.

Altman said that OpenAI is very happy to cooperate with Amazon to bring new - generation products to the market and looks forward to making full use of Trainium chips; NVIDIA has always been one of OpenAI's most important partners, and its chips are the cornerstone of artificial intelligence computing. He is very happy to run their systems on AWS and is looking forward to NVIDIA's new products; SoftBank is an excellent partner, and he is very glad that it has become an important investor in OpenAI again and looks forward to more extensive cooperation.

He also mentioned that Microsoft will still cooperate with OpenAI. OpenAI's stateless API will continue to be exclusively provided to Azure, and it will expand more computing resources together with Microsoft.

Amazon Invests in OpenAI, Supplies Chips

Becomes the Exclusive Third - Party Cloud Provider for the Frontier Platform

OpenAI announced a multi - year strategic partnership with Amazon. Amazon will invest $50 billion in OpenAI. The first - batch investment is $15 billion, and after meeting specific conditions, it will invest an additional $35 billion in the next few months.

The partnership they reached includes:

AWS and OpenAI will jointly create a Stateful Runtime Environment driven by OpenAI models. This environment will be available on Amazon's Bedrock platform, allowing AWS customers to build generative AI applications and Agents at a production scale. The Stateful Runtime Environment is expected to be launched in the next few months.

Its blog mentioned that the stateful developer environment is the next - generation application of cutting - edge models, enabling models to seamlessly access elements such as computing, memory, and identity. The Stateful Runtime Environment allows developers to maintain context, remember previous work, collaborate across software tools and data sources, and access computing. It is designed to handle ongoing projects and workflows.

AWS will become the exclusive third - party cloud distribution provider for the enterprise - level AI platform OpenAI Frontier, which helps organizations build, deploy, and manage teams of AI Agents.

Frontier enables enterprises to build, deploy, and manage teams of AI Agents across real - world business systems, with shared context, built - in governance, and enterprise - level security, without having to manage the underlying infrastructure.

OpenAI will consume 2 gigawatts of Trainium computing power through AWS infrastructure to support the needs of the Stateful Runtime Environment, Frontier, and other advanced workloads.

In November 2025, OpenAI announced a $38 - billion computing power agreement with AWS. Now, it plans to add an additional $100 billion to this agreement over the next eight years.

The latest cooperation will cover Trainium3 chips and the next - generation Trainium4 chips, providing computing power support for various high - order artificial intelligence workloads. Trainium4 is expected to be delivered in 2027, offering higher FP4 computing performance, wider memory bandwidth, and larger high - bandwidth memory capacity.

OpenAI and Amazon will develop customized models to drive Amazon's customer - facing applications.

The Amazon team will be able to customize OpenAI models for AI products and Agents that directly serve customers. These features will complement the models already available to Amazon developers, including Amazon's Nova series, providing the team with another tool for large - scale construction and delivery.

Reaffirm the Cooperation with Microsoft

OpenAI also issued a joint statement with Microsoft.

The terms mentioned in it include:

The cooperation between the two parties remains strong and at the core: Microsoft and OpenAI will continue to cooperate closely in the fields of research, engineering, and product development based on years of in - depth collaboration and shared achievements.

The intellectual property cooperation relationship between the two parties remains unchanged: Microsoft will continue to hold the exclusive license and right to use the intellectual property of OpenAI's various models and products. The cooperation between OpenAI and Amazon was already planned within the framework of the agreement between the two parties, and Microsoft also looks forward to seeing the results they achieve together.

The business cooperation and revenue - sharing relationship between the two parties remains unchanged: The current revenue - sharing arrangement remains the same, and this mechanism always includes the sharing of revenue generated from OpenAI's cooperation with other cloud service providers.

Azure remains the exclusive cloud service provider for OpenAI's stateless API: Microsoft is the exclusive cloud service provider for the stateless API that provides access to OpenAI's models and intellectual property. These APIs can be purchased through Microsoft or directly from OpenAI. All stateless API calls to OpenAI models generated from OpenAI's cooperation with any third party will be hosted on Azure.

OpenAI's first - party products, including Frontier, will continue to be hosted on Azure.

The definition and process of AGI remain unchanged: The contractual definition of AGI and the procedure for determining whether it has been achieved remain unchanged.

This cooperation will help OpenAI achieve development: As OpenAI continues to scale up, it still has the flexibility to invest additional computing power on other platforms, including large - scale infrastructure projects such as building the Stargate.

The blog finally mentioned that the original intention of the cooperation between the two parties was to reserve space for Microsoft and OpenAI to independently explore new opportunities while continuing to collaborate. Currently, the two companies are doing just that - cooperating hand in hand while also developing independently.

Conclusion: A Luxury Capital Group Bets on OpenAI

OpenAI Faces Pressure to Go Public and Sprint towards AGI

At the beginning of 2026, star AI startups in Silicon Valley have successively received large - scale financing. In January, Elon Musk's AI unicorn xAI announced the completion of a $20 - billion Series E financing, with NVIDIA participating; in January, Anthropic was reported to be planning to raise $10 billion at a valuation of $350 billion; in February, World Labs, a spatial intelligence startup founded by Fei - Fei Li, announced the completion of a new round of $1 - billion financing, with NVIDIA and AMD participating. Coupled with the latest OpenAI financing, a series of financing worth tens of billions and hundreds of billions of dollars are being implemented intensively.

In comparison, OpenAI's ability to attract capital is still at the top level in the AI industry. The luxury investment lineup of Amazon, NVIDIA, and SoftBank, along with the $110 - billion investment, is rare in the industry.

Next, it may rely on sufficient funds and strategic partner resources to accelerate infrastructure construction, research and development of next - generation models, and global commercial expansion; at the same time, it will also drive the full - line upgrade of the industrial chain such as data centers, high - speed interconnection, and customized chips, reshaping the global AI computing power supply chain and the right to speak in technical standards.

However, according to reports from multiple foreign media, many investors hope that OpenAI can go public as soon as possible and accelerate the progress towards the goal of general artificial intelligence. This demand may make OpenAI pay more attention to the return expectations of the capital market and commercialization pressure.
