TLDR
- Four private equity firms—TPG, Advent International, Bain Capital, and Brookfield Asset Management—are negotiating with OpenAI to establish a joint venture carrying a $10 billion valuation.
- These PE firms plan to contribute $4 billion collectively, securing equity positions and board representation in the new entity.
- Anthropic has initiated separate discussions with Blackstone, Permira, and Hellman & Friedman for a comparable partnership, involving approximately $1 billion from the PE firms.
- Both artificial intelligence companies aim to secure major corporate partnerships ahead of anticipated IPOs scheduled for later in 2025.
- The ventures differ in structure: OpenAI proposes preferred equity stakes while Anthropic offers common equity arrangements with reduced investor safeguards.
Four prominent private equity firms have entered advanced negotiations with OpenAI to establish a joint venture focused on delivering AI solutions to enterprise customers. TPG, Advent International, Bain Capital, and Brookfield Asset Management are the firms participating in these discussions, according to sources cited by Reuters.
The prospective venture would carry a pre-money valuation approaching $10 billion. The coalition of private equity firms plans to inject $4 billion in combined capital, receiving equity ownership in exchange. TPG will assume the leading investor role, contributing the largest capital commitment among the participants.
Board representation in the new venture will extend to all four participating firms. The arrangement would provide them with priority access to OpenAI’s enterprise product suite and participation in growth opportunities extending beyond their existing portfolio holdings.
OpenAI’s corporate business division currently produces $10 billion in annualized revenue, representing a significant portion of the company’s $25 billion total. The joint venture structure serves as a catalyst for accelerating enterprise adoption of OpenAI’s technology offerings.
Distribution of OpenAI’s enterprise platform, Frontier, would fall under the venture’s purview. This platform debuted last month within the Frontier Alliances program, which connects OpenAI’s engineering talent with major consulting organizations including BCG, McKinsey, Accenture, and Capgemini.
Anthropic Running a Parallel Process
Anthropic has initiated comparable negotiations with its own roster of private equity partners. The discussions involve Blackstone, Permira, and Hellman & Friedman.
The proposed Anthropic partnership would involve an equity investment totaling approximately $1 billion from the participating private equity firms. Anthropic’s proposal centers on common equity positions, which differ substantially from the preferred equity structure OpenAI presents to its potential partners.
Preferred equity in OpenAI’s venture offers investors priority distribution rights and downside protection mechanisms. Common equity in Anthropic’s arrangement lacks these enhanced investor safeguards.
The Information initially disclosed last week that Anthropic had engaged in preliminary talks with Blackstone and Hellman & Friedman. None of the entities involved in either transaction have issued confirmations regarding finalized terms.
The Race to Go Public
Both companies recognize the strategic importance of partnering with private equity firms, given their influence over extensive corporate portfolios and decision-making authority regarding software and AI investment allocations.
IPO preparation timelines add urgency to these negotiations. Industry reports suggest both OpenAI and Anthropic are targeting public market debuts within the current calendar year.
Within enterprise AI markets, Anthropic has established a reputation for stronger corporate adoption metrics compared to OpenAI. The joint venture framework represents OpenAI’s strategic response to narrow this competitive gap.
Fidji Simo, CEO of Applications at OpenAI, said in a statement: “As demand for AI continues to skyrocket, we want to help our customers deploy these technologies in all the ways that help them create impact.”
She added that OpenAI is “building a deployment arm that works directly with enterprises and partners to deeply embed AI throughout their organizations.”
Neither set of negotiations has produced final binding agreements, with all involved parties indicating that structural details remain open to modification.
