OpenAI closes $110 billion funding round with backing from Amazon, Nvidia, Softbank. Valuing company at $730 billion.

OpenAI has completed a landmark $110 billion funding round, securing investments from strategic giants Amazon, Nvidia, and SoftBank's Vision Fund 2. This colossal financing values the San Francisco-based AI leader at approximately $730 billion, a figure that dwarfs its previous valuation and positions it among the most valuable technology companies globally, public or private. The round represents a seismic shift in the AI capital landscape, signaling unprecedented confidence from industry titans in OpenAI's path to artificial general intelligence (AGI) and its commercial dominance. It follows intense competition with well-funded rivals like Anthropic, which has raised over $10 billion, and reflects the enormous capital requirements for training next-generation models and building global AI infrastructure.

The funding is expected to be deployed across several critical areas: procuring hundreds of thousands of next-generation NVIDIA Blackwell GPUs and other AI accelerators, scaling up frontier model research (including the development of GPT-5 and beyond), and expanding its global cloud infrastructure and enterprise sales operations. For investors, Amazon gains deeper integration for its AWS cloud platform, Nvidia secures a flagship customer for its hardware, and SoftBank bets on the defining technology of the next decade. The round effectively creates a war chest that could accelerate the AI arms race, potentially widening the gap between OpenAI and smaller competitors. It also raises questions about market concentration and the future governance of a company whose technology could reshape the global economy.
