The round was anchored by Amazon, Nvidia, and SoftBank. Microsoft, an existing backer, also participated. SoftBank co-led alongside a16z, D.E. Shaw Ventures, MGX, TPG, and T. Rowe Price-advised accounts.
The investor list includes BlackRock, Blackstone, Fidelity, Sequoia, Temasek, Coatue, ARK Invest, Thrive Capital, and Insight Partners, among others.
For the first time, OpenAI opened the round to individual investors through bank channels, raising over $3 billion from that group alone. OpenAI will also be included in several ARK Invest ETFs.
OpenAI says it now generates $2 billion in monthly revenue. That compares to $1 billion per quarter at the end of 2024, showing fast growth over a short period.
ChatGPT has more than 900 million weekly active users and over 50 million paying subscribers. The company claims six times the monthly web visits of the next largest AI app.
Enterprise revenue now makes up more than 40% of total revenue. OpenAI says enterprise is on track to reach parity with consumer revenue by the end of 2026.
The company’s APIs process more than 15 billion tokens per minute. Its coding agent, Codex, serves over 2 million weekly users, up five times in just three months.
OpenAI’s Superapp Plans
OpenAI says it is building a unified AI superapp that brings together ChatGPT, Codex, browsing, and agentic features into one product. The goal is to make its models easier to use at scale.
The company framed compute infrastructure as a key strategic asset. Cloud partners include Microsoft, Oracle, AWS, CoreWeave, and Google Cloud. Chip partners include Nvidia, AMD, AWS Trainium, Cerebras, and a custom chip being built with Broadcom.
Credit Facility and Valuation Context
OpenAI also expanded its revolving credit facility to approximately $4.7 billion. It is supported by JPMorgan Chase, Citi, Goldman Sachs, Morgan Stanley, Wells Fargo, and others. The facility remains undrawn as of March 31.
At $852 billion, OpenAI’s valuation is roughly on par with Berkshire Hathaway. It exceeds the market caps of Visa, JPMorgan Chase, and Samsung.
OpenAI recently launched GPT-5.4. The company’s APIs continue to scale, processing billions of tokens per minute across enterprise and consumer use cases.
