On February 28, OpenAI announced it had completed a $110 billion Capital round, valuing the company at approximately $730 billion, making it the largest Capital deal in the history of the US technology industry.
In an announcement on February 27th, OpenAI stated that it had received investments from major technology companies, including $50 billion from Amazon, $30 billion from Nvidia, and $30 billion from Soybank. This brought the company's valuation to $730 billion, a significant increase from the $500 billion valuation in its October Capital round. This figure is expected to continue rising as the Capital round continues.
"We are entering a new phase where advanced AI is moving from research to everyday applications on a global scale," OpenAI stated in its blog. "Position and leadership will be determined by their ability to scale infrastructure quickly enough to meet demand, and to translate that capability into products that people trust."
"We are extremely excited about the deal," OpenAI CEO Sam Altman told CNBC . "AI is going to be everywhere and is transforming the entire economy. The world needs a lot of collective computing power to meet that need."
Under the agreement with Amazon, OpenAI plans to develop a new "selective testing environment" where OpenAI's models will run on Amazon's Bedrock platform. Altman's company also expanded its collaboration with AWS by committing $38 billion to computing services and utilizing at least 2 GW of AWS Trainium, as well as plans to build custom models to serve Amazon's consumer products.
OpenAI did not provide details about its partnership with Nvidia. However, the company stated that it has committed to using "3 GW of dedicated inference power and 2 GW of training power on the Vera Rubin system."
Earlier in September 2025, Nvidia announced plans to invest $100 billion in OpenAI to build a massive data center for training and operating artificial intelligence models. Under the terms, Nvidia planned to invest in 10 tranches, each worth $10 billion, to meet OpenAI's growing computing needs over the next several years. In return, they would receive a significant ownership stake in the startup.
However, some sources later reported a disagreement between OpenAI and Nvidia. Nvidia CEO Jensen Huang denied this and affirmed that the company would invest heavily in the startup. Nevertheless, the current investment is at $30 billion instead of the initially planned $100 billion.
With Microsoft – one of the first companies to invest billions of dollars in OpenAI – Altman said there were "no changes to any terms" of the agreement between the two companies. In a joint statement on February 27, both emphasized that the partnership remains "strong and important."
Last week, OpenAI announced its goal of spending a total of $600 billion on computing by 2030. Late last year, CEO Altman announced a commitment to invest $1.4 trillion in artificial intelligence infrastructure.
Citing internal sources, CNBC reported that OpenAI expects its total revenue to exceed $280 billion by 2030, primarily from its consumer and enterprise businesses.
