OpenAI Eyes Record Private Round, but Who Will Anchor It?
TREE NEWS reports: OpenAI has begun early talks with investors for a new private funding round that could value the artificial-intelligence company at $1.2 trillion or more. The move comes just days after CEO Sam Altman said the company will not pursue an initial public offering this year, keeping OpenAI in private markets where it can chase revenue growth without disclosing the full cost of that expansion.
The central question hanging over the deal is not whether OpenAI wants the money — it is who can write a check large enough to anchor it. OpenAI has already raised or secured commitments totaling roughly $182 billion, a record for a private company and well ahead of rival Anthropic’s $130 billion. But its largest existing shareholders are now facing capital constraints of their own, leaving a shrinking pool of potential lead investors.
Why OpenAI Stays Private
Altman’s decision to forgo an IPO this year gives OpenAI a critical buffer. As a private company, it does not have to disclose to public shareholders the heavy discounts it is offering to win business from Anthropic — discounts that are compressing margins even as user numbers climb. OpenAI’s annualized revenue run rate has surpassed $40 billion, but that still trails Anthropic’s $65 billion, and the company has projected that server rental costs for AI model training alone will consume about $170 billion cumulatively through 2028.
A $1.2 trillion private valuation would set the stage for an eventual IPO at around $1.5 trillion, a level comparable to outside estimates for Anthropic’s own listing. Early backers would be sitting on roughly 25% paper gains — an attractive headline, but one that depends entirely on finding new capital willing to underwrite the next leg of growth.
The Anchor Investor Problem
OpenAI has already drawn nearly every major institutional investor into its cap table. A $122 billion round announced in March included close to 30 participants, spanning asset managers such as T. Rowe Price, Fidelity and BlackRock; crossover funds including Coatue Management, D1 Capital Partners and Dragoneer Investment Group; and top Silicon Valley venture firms like Andreessen Horowitz and Sequoia Capital.
Yet few of those firms can comfortably deploy tens of billions of dollars more. The largest shareholders are themselves under pressure:
- SoftBank has applied for nearly $12 billion in loans to deliver the final $10 billion of its OpenAI commitment.
- Amazon projected capital expenditure of $200 billion this year, likely far exceeding its operating cash flow.
- Nvidia is providing up to $105 billion in credit support for OpenAI’s large data center in Ohio — already a heavy off-balance-sheet burden.
Any of these companies increasing their OpenAI stakes further would likely raise alarms among their own creditors and shareholders.
Could Suppliers Step In?
With traditional backers stretched, OpenAI’s chip and compute suppliers have emerged as the most plausible source of new capital. The logic is straightforward: if OpenAI keeps growing, those suppliers benefit directly, making an investment a strategic way to deepen the relationship. Broadcom, which is co-developing custom chips with OpenAI, held about $24 billion in cash and equivalents as of August, making it one of the few potential buyers with real flexibility.
But whether OpenAI’s revenue can actually accelerate remains the biggest unknown. Recent product launches — including the Codex coding tool and new models such as 5.6 and Astra — have been accompanied by price cuts that cloud the revenue outlook. Adding to the uncertainty, some OpenAI researchers have publicly called for slowing the pace of model development until safety practices catch up, exposing internal divisions over the company’s direction.
Key Takeaways for Investors
- Private-market concentration risk: A $1.2 trillion valuation would make OpenAI one of the most valuable private companies ever, but the buyer base is narrowing. If existing backers cannot step up, the round may need to rely on strategic investors with conflicted interests.
- Watch the suppliers: Broadcom, Nvidia and other compute providers are the most likely candidates to anchor the round. Any commitment from them would signal confidence in OpenAI’s long-term demand — but also deepen the circularity between AI model makers and their infrastructure vendors.
- IPO timing matters: Altman’s decision to stay private delays public disclosure of OpenAI’s cost structure. When an IPO eventually comes, investors should expect a hard look at margins, discounting and compute costs.
- Competitive pressure is real: OpenAI’s revenue growth is strong but still behind Anthropic’s. Price cuts may boost adoption, but they also raise questions about the durability of the business model.
- Broader AI trade implications: The outcome of this round will influence sentiment across AI-linked equities, from chipmakers to cloud providers. A successful raise at $1.2 trillion would reinforce the bull case; a stumble could trigger a reassessment of valuations across the sector.
