OpenAI closes $110B round at $730B valuation with SoftBank, NVIDIA, and Amazon

OpenAI, the artificial intelligence research lab developing advanced language models, announced Friday that the company has secured $110 billion in a new funding round backed by SoftBank, NVIDIA, and Amazon at a $730 billion pre-money valuation.

SoftBank, the Japanese investment conglomerate behind major tech initiatives, and NVIDIA, a leading supplier of AI computing hardware, each committed $30 billion. Amazon, operator of the dominant AWS cloud platform, contributed $50 billion and entered a multi-year strategic partnership to accelerate AI adoption across enterprise and consumer markets.

The San Francisco–based AI lab plans to use the capital to expand capacity, global product distribution, and commercialization of frontier AI systems to meet surging demand for the company’s products. Its ChatGPT conversational AI platform now reaches more than 900 million weekly active users and has surpassed 50 million consumer subscribers.

“We’re pushing the frontier across infrastructure, research, and products to make AI more capable, reliable, and broadly useful,” said Sam Altman, co-founder and chief executive.

Business adoption has also climbed, with more than nine million paying corporate users now relying on the platform for daily operations. Codex, the firm’s AI-powered coding assistant, has seen its weekly user base triple since January to 1.6 million.

Under the expanded arrangement with NVIDIA, the company gains access to 3 gigawatts of dedicated inference capacity and 2 gigawatts of training power using next-generation Vera Rubin systems. These resources build on existing deployments of Hopper and Blackwell hardware operated through Microsoft, Oracle Cloud, and CoreWeave.

The new valuation lifts the OpenAI Foundation’s stake in the broader corporate group above $180 billion, strengthening its capacity to fund philanthropic work in areas such as health research and AI resilience.

By September 2025, the company had committed to a $300 billion infrastructure agreement with Oracle and acquired enterprise analytics firm Statsig for $1.1 billion. Industry projections estimate cumulative AI compute spending could exceed $450 billion between 2024 and 2030.
