Today we’re announcing new investment, with support from @SoftBank, @NVIDIA, and @Amazon, to scale the infrastructure needed to bring AI to everyone.https://t.co/xW0ItgMTLe
According to the Financial Times, this is the largest funding round in startup history.
In February, OpenAI's competitor, AI startup Anthropic, raised $30 billion at a valuation of $380 billion, with major investors including D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, and MGX.
Earlier in January, the chatbot developer Grok — xAI — also secured $20 billion with support from Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, and other partners.
Additional participants are expected to join the deal with OpenAI.
“SoftBank, Nvidia, and Amazon are long-term partners who share our commitment to turning real scientific achievements into systems that provide tangible benefits to millions of people worldwide,” commented CEO Sam Altman.
The funds will be used to expand global presence, enhance infrastructure, and strengthen the balance sheet.
This new round has increased the OpenAI Foundation's stake in the company to over $180 billion, enabling the nonprofit to finance projects in healthcare and AI safety.
In October, reports indicated that Altman's company is preparing for an IPO with a valuation of $1 trillion. Reuters sources expect a filing in the second half of 2026.
Collaborations with Amazon and Nvidia
As part of the deal, the ChatGPT developer has formed a strategic partnership with Amazon.

The companies are jointly developing a runtime environment based on OpenAI models, accessible through Amazon Bedrock. This technology will allow neural networks to maintain context, manage computational resources, memory, and identification, and integrate with existing applications in AWS. The launch is expected in the coming months.
Amazon Web Services will be the sole third-party provider for OpenAI Frontier. Companies will be able to create and coordinate AI agents with corporate security without managing infrastructure.
Additionally, under an eight-year agreement worth $100 billion (in addition to the existing $38 billion deal), OpenAI will utilize approximately 2 GW of Trainium capacity on AWS infrastructure. This will provide the company with long-term computing resources and reduce the cost of scaling AI.
The startup has also expanded its long-term collaboration with Nvidia, adding 3 GW of dedicated capacity for inference and 2 GW for training on Vera Rubin systems. This will complement the already deployed Hopper and Blackwell on Microsoft, OCI, and CoreWeave platforms.
Notably, in February, OpenAI reduced its spending plan for computing power by 2030 from $1.4 trillion to $600 billion.
