Key Takeaways
- OpenAI's $122 billion raise at an $852 billion valuation is the largest private funding round in history.
- The capital will fund a unified "superapp" merging ChatGPT, Codex, browsing and agentic tools into a single platform.
- OpenAI is diversifying its compute infrastructure across five cloud providers, five chip platforms and multiple data center partners.
OpenAI closed $122 billion in committed capital on March 31, 2026, at a post-money valuation of $852 billion. Amazon, NVIDIA and SoftBank anchored the round, with continued backing from Microsoft. SoftBank co-led alongside a16z, D. E. Shaw Ventures, MGX, TPG and accounts advised by T. Rowe Price Associates.
A broad coalition of institutional investors also participated, including Sequoia Capital, BlackRock affiliates, Blackstone, Fidelity, Temasek and ARK Invest, among others.
For the first time, OpenAI extended access to individual investors through bank channels, raising over $3 billion. The company also announced it will be included in several ARK Invest exchange-traded funds.
Separately, OpenAI expanded its revolving credit facility to approximately $4.7 billion, backed by a syndicate of 11 banks including JPMorgan Chase, Citi, Goldman Sachs and Morgan Stanley. The facility remains undrawn.

OpenAI Drops Plans of Unified AI ‘Superapp’
"As models become more capable, the limiting factor shifts from intelligence to usability. Users do not want disconnected tools. They want a single system that can understand intent, take action, and operate across applications, data, and workflows."
- OpenAI Official Statement
The centerpiece of OpenAI's plan is what the company calls an AI "superapp" — a single platform merging ChatGPT, its Codex coding agent, web browsing and agentic capabilities into one product.
OpenAI framed the move as a response to AI adoption limitations: not model intelligence, but usability. The company said users want a single system that can understand intent, take action and operate across applications and workflows rather than a set of disconnected tools.
The tech company described the superapp as both a product and a distribution strategy. Consumer familiarity with ChatGPT becomes a gateway to enterprise adoption, and a unified surface lets the company ship model improvements directly to users rather than across fragmented products.
Scaling Compute Across Partners
A significant share of the capital will go toward expanding global compute infrastructure. OpenAI has broadened its infrastructure strategy beyond a small number of core providers to span multiple clouds, chip platforms and data center partnerships.
On the cloud side, the company now works with Microsoft, Oracle, AWS, CoreWeave and Google Cloud. Its silicon strategy includes NVIDIA (which remains the foundation of its training and inference stack), AMD, AWS Trainium, Cerebras and a custom chip effort with Broadcom. Data center partnerships run through Oracle, SBE and SoftBank.
OpenAI described this diversification as a necessity: demand for AI systems is growing faster and becoming more varied than any single architecture can handle.
The Numbers Behind the Momentum
ChatGPT now has more than 900 million weekly active users and over 50 million subscribers. The company says it has six times the monthly web visits and mobile sessions of the next largest AI app, and four times the total time spent.
Revenue has scaled rapidly. OpenAI said it:
- Hit $1 billion in annual revenue within a year of launching ChatGPT
- Reached $1 billion per quarter by end of 2024
- Is now generating $2 billion per month
Enterprise revenue accounts for more than 40% of total revenue and is on track to reach parity with consumer by the end of 2026.
On the product side, OpenAI recently launched GPT-5.4, featuring a one-million-token context window and native computer control. Codex now serves over 2 million weekly users, up fivefold in three months. APIs process more than 15 billion tokens per minute. The company also noted that its advertising pilot surpassed $100 million in annualized revenue in under six weeks.
The Broader Expansion, 2024-2026
The funding round caps two years of aggressive moves. OpenAI completed multiple acquisitions, with some of the most notable including:
- Promptfoo for red-teaming and security (March 2026)
- Neptune for under $400 million for model governance (December 2025)
- Statsig for $1.1 billion (September 2025)
- Multi for collaboration tools (June 2024)
On infrastructure, OpenAI locked in major compute commitments: a deal positioning NVIDIA to invest up to $100 billion as its primary chip supplier, a $38 billion AWS cloud contract a restructured Microsoft agreement preserving a $250 billion Azure commitment and participation in the $500 billion Stargate joint venture with SoftBank and Oracle.
The company also transitioned its for-profit arm to a Public Benefit Corporation in May 2025, with the OpenAI Foundation retaining a 26% equity stake.
