Helping AI reach more people requires deep collaboration across the ecosystem.

According to the Financial Times, this is the largest funding round in startup history.

In February, a rival firm, AI startup Anthropic, raised $30 billion at a $380 billion valuation. The main investors were D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, and MGX.

Earlier in January, the developer of the chatbot Grok, xAI, also secured $20 billion with support from Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, and other partners.

Other participants are expected to join the OpenAI deal.

“SoftBank, Nvidia, and Amazon are long-term partners who share our commitment to turning real scientific advances into systems that deliver tangible benefits to millions of people worldwide,” commented the firm’s CEO, Sam Altman.

The funds will be directed towards expanding global presence, deepening infrastructure, and strengthening the balance sheet.

The new round has increased the OpenAI Foundation’s stake in the firm to over $180 billion. This will enhance the non-profit’s ability to fund projects in healthcare and AI safety.

In October, media reported that Altman’s company is preparing for an IPO with a valuation of $1 trillion. Reuters sources expect the filing in the second half of 2026.

Collaborations with Amazon and Nvidia

As part of the deal, the ChatGPT developer has entered into a strategic partnership with Amazon.

The companies are jointly developing an execution environment based on OpenAI models, available through Amazon Bedrock. The technology will enable neural networks to maintain context, work with computing resources, memory, and identification, and integrate with existing applications in AWS. The launch is expected in the coming months.

Amazon Web Services will become 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 an existing $38 billion deal), OpenAI will use about 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 multi-year 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.

Back in February, OpenAI reduced its planned computing power expenditure by 2030 from $1.4 trillion to $600 billion.
