OpenAI has secured one of the biggest private funding rounds in tech history after raising $110 billion from major global investors.
In a blog post titled “Scaling AI for Everyone,” OpenAI confirmed the new capital injection. The deal pushes its pre-money valuation to $730 billion and underlines the huge demand for artificial intelligence infrastructure.
The round is led by three tech giants. Amazon is investing $50 billion, Nvidia is committing $30 billion, and SoftBank is adding another $30 billion. It marks Amazon’s largest single investment in any company so far.
Amazon’s deal includes an initial $15 billion payment, with the remaining $35 billion tied to performance milestones. The agreement also deepens OpenAI’s partnership with Amazon Web Services, giving the AI firm access to large-scale cloud infrastructure and Trainium AI chips. Nvidia will provide next-generation AI accelerators, while SoftBank continues its long-term backing of advanced AI projects.
CEO Sam Altman said the partners share a common goal of turning scientific progress into systems that benefit people worldwide. He described the investment as a major step toward building more powerful and useful AI models.
The fresh funding will help OpenAI cover the massive costs of training new models, building data centers, and hiring top researchers. It also increases the value of the OpenAI Foundation’s stake in the company, strengthening its ability to support work in AI safety and health research.
Market watchers say the move shows how closely AI developers are now tied to cloud and chip providers. Some reports suggest OpenAI’s valuation could climb above $840 billion if more investors join, as the round remains open.
The funding comes as speculation grows about a possible IPO later in 2026. If that happens, it could become one of the largest public listings in history.
