Briefing

OpenAI has closed a $122bn funding round at a post-money valuation of $852bn, surpassing any prior private capital raise and placing the company alongside Berkshire Hathaway in terms of implied worth. Amazon, Nvidia, and SoftBank anchored the round, with Microsoft continuing its participation alongside a roster that includes BlackRock, Blackstone, Sequoia, and Temasek. For the first time, individual investors were admitted through bank channels, contributing more than $3bn. The company now reports $2bn in monthly revenue and 900 million weekly ChatGPT users.

OpenAI closes $122bn round at $852bn valuation

OpenAI has raised $122bn in committed capital at an $852bn post-money valuation, closing what multiple outlets and the company itself describe as the largest private funding round ever completed. The round was anchored by Amazon, Nvidia, and SoftBank, with continued backing from Microsoft. SoftBank co-led alongside Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, and accounts advised by T. Rowe Price. BlackRock, Blackstone, Fidelity, Sequoia, Temasek, Coatue, and ARK Invest also participated.

The raise exceeded the $110bn figure OpenAI had flagged a month earlier, according to CNBC and The Guardian. SoftBank alone committed $110bn, per the Wall Street Journal.

**Retail access and credit facilities**

In a structural departure, OpenAI admitted individual investors through bank channels for the first time, raising more than $3bn from that tranche alone. The move, noted by Axios, TechCrunch, and the Financial Times, is widely read as a precursor to a public listing, with CNBC and Forbes both reporting that groundwork for an IPO is being laid.

The company simultaneously expanded its revolving credit facility to approximately $4.7bn, with JPMorgan Chase, Citigroup, Goldman Sachs, and Morgan Stanley among the supporting banks. That facility remained undrawn as of 31 March.

**Revenue trajectory and usage metrics**

OpenAI said it now generates $2bn in monthly revenue, a step-change from $1bn per quarter at the end of 2024. ChatGPT has more than 900 million weekly active users and over 50 million paid subscribers. Enterprise accounts for more than 40% of revenue and is on track to reach parity with consumer by end of 2026. The company's APIs process more than 15 billion tokens per minute, and Codex, its coding agent, has grown to 2 million weekly users, up fivefold in three months.

**Infrastructure and strategic direction**

OpenAI framed the capital raise around compute capacity as a competitive necessity. Its cloud infrastructure now spans Microsoft, Oracle, AWS, CoreWeave, and Google Cloud. On the silicon side, the company works with Nvidia, AMD, AWS Trainium, Cerebras, and is developing a custom chip with Broadcom. The company also described plans for a unified AI application combining ChatGPT, Codex, browser-based tools, and agentic functions into a single product, on the thesis that as model capability improves, the binding constraint shifts to usability and distribution.

**Valuation context**

At $852bn, OpenAI is comparable in implied value to Berkshire Hathaway and exceeds Visa, JPMorgan Chase, and Samsung. It remains a private company, and the valuation is based solely on the terms of the fundraising round.

Analysis

The inclusion of an ETF manager in the round creates a listed vehicle with direct OpenAI exposure before any IPO. This draws retail capital into a pre-IPO position via the ETF wrapper, which compresses the traditional IPO demand surge by pre-distributing the stakeholder base. When OpenAI does list, the float dynamic will be atypical: a segment of retail holders will already carry the position, reducing the new-money pool that typically drives first-day price discovery.
Amazon and Nvidia each deepening financial stakes in OpenAI while also being its infrastructure suppliers creates a structural conflict that will complicate OpenAI's vendor negotiations at scale. Both companies now have equity upside tied to OpenAI's growth, but also margin interest in charging market rates for compute and silicon. This dual role limits OpenAI's leverage in procurement and reinforces Nvidia's pricing power on GPU contracts, compounding the read-through from Nvidia's Marvell stake in building a captive ecosystem.

Nvidia takes $2bn stake in Marvell in latest AI ecosystem bet

Nvidia's $2bn equity stake in Marvell, taken alongside its $110bn institutional commitment to OpenAI, confirms a deliberate strategy of converting commercial relationships into balance-sheet positions across the AI supply chain. The OpenAI investment is the largest expression of this pattern, tightening Nvidia's claim on AI infrastructure economics at both the silicon and application layers simultaneously.

Mistral AI raises $830mn in debt to build Nvidia-powered data centre near Paris

Mistral's $830mn debt raise to build Nvidia-powered European AI infrastructure and OpenAI's $122bn round closing in the same week confirm that AI capex financing has reached a scale where both debt and equity markets are being tapped concurrently across geographies. The combined demand for Nvidia hardware from these two transactions alone illustrates the GPU procurement backlog risk that is now embedded in any AI infrastructure build timeline.

OECD warns Iran war will push US inflation to 4.2%, erasing global growth gains

The OECD's 4.2% US inflation forecast and the resulting stagflationary hold by the Fed directly constrain the IPO window OpenAI is preparing to enter. Elevated rates compress the discounted cash flow math on a pre-profitability issuer at a sub-$1 trillion valuation, and the consumer sentiment deterioration documented through March reduces the retail demand pool that the ETF distribution strategy is designed to reach.
