OpenAI has closed a massive new funding round, announcing $110 billion in new investment at a $730 billion pre-money valuation, according to the company's own blog. The round is anchored by three heavyweight backers: $30 billion from SoftBank, $30 billion from NVIDIA, and $50 billion from Amazon.
A separate OpenAI announcement put the total new funding figure at $122 billion, framing the capital raise as fuel to "expand frontier AI globally, invest in next-generation compute, and meet growing demand" for products including ChatGPT, Codex, and its enterprise AI offerings.
The involvement of NVIDIA — the dominant supplier of AI chips — and Amazon, which runs one of the world's largest cloud platforms, signals that OpenAI's biggest infrastructure partners are now also major financial stakeholders. SoftBank, long known for placing outsized bets on technology companies, rounds out a trio that collectively controls critical pieces of the AI supply chain.
The funding lands against a broader backdrop of tech giants pursuing record valuations. According to the Wall Street Journal, SpaceX's recent market debut brought its value to $2.1 trillion, and analysts are watching whether OpenAI and Anthropic could follow with what the Journal described as potentially among the largest IPOs in history.
At $730 billion, OpenAI now ranks among the most valuable private companies ever — a striking figure for an organization that began as a nonprofit research lab less than a decade ago. The scale of this raise matters because it determines how much compute, talent, and global infrastructure OpenAI can deploy at a moment when the race to build the most capable AI systems is intensifying by the month.
