Backed by Amazon, Nvidia and SoftBank, the $110B deal values the ChatGPT maker at about $730B
OpenAI has raised $110 billion in fresh funding from Amazon, Nvidia and SoftBank, in what has been considered one of the largest private funding rounds in history.
Amazon is committing $50 billion, starting with $15 billion upfront and a further $35 billion tied to milestones such as an eventual IPO or technical progress. Nvidia and SoftBank are each investing $30 billion, and OpenAI says additional investors may still join the round.
The raise, which now values the ChatGPT maker at about $730 billion, is the latest turn in a striking funding journey. OpenAI began in 2015 as a nonprofit lab, with well-known backers pledging $1 billion but only around $130 million actually contributed by 2019.
In 2019 it adopted a “capped-profit” structure and secured a $1 billion partnership with Microsoft, which has since expanded into more than $13 billion of investment and cloud credits. In 2025, OpenAI completed a $6.6 billion employee share sale that valued the company at $500 billion.
Today’s round also rewires OpenAI’s strategic alliances. Amazon Web Services will become OpenAI’s exclusive third-party cloud provider for its new enterprise platform, OpenAI Frontier, while OpenAI commits to run workloads on Amazon’s Trainium chips.
At the same time, Microsoft retains its role as exclusive cloud provider for OpenAI’s public API services, and its existing licensing deals remain in place.
OpenAI says the new capital will largely fund energy-hungry infrastructure for training and deploying frontier models.
With around 900 million weekly users and 50 million consumer subscribers, the company argues that investor appetite is matching AI’s rapid move from research experiment to everyday utility.
