SAN FRANCISCO, CALIFORNIA – OpenAI said Friday (February 27, 2026) that it has secured $110 billion in new investment in what ranks among the largest private funding rounds ever, pegging the company at a $730 billion pre-money valuation.
Who put up the money
OpenAI says the round includes:
- Amazon: $50 billion
- Nvidia: $30 billion
- SoftBank: $30 billion
OpenAI also noted the round is expected to expand with additional financial investors as it progresses.
The funding is not just about cash — it is tied to major infrastructure commitments.
Reuters reported that Amazon Web Services will become the exclusive third-party cloud provider for OpenAI Frontier (OpenAI’s enterprise platform for managing AI agents), and that OpenAI will use 2 gigawatts of compute running on Amazon’s Trainium chips as part of the deal.
OpenAI emphasized that its relationship with Microsoft remains intact. Reuters reported Microsoft Azure stays the exclusive cloud provider for OpenAI’s API services, and Microsoft’s exclusive license to OpenAI models and products remains unchanged.
