OpenAI Offers Private Equity Firms 17.5% Guaranteed Returns to Beat Anthropic in Enterprise Race

OpenAI is offering private equity firms a guaranteed minimum return of 17.5% to win their participation in a joint venture targeting enterprise AI distribution, Reuters reported today, as both OpenAI and Anthropic race to lock up access to buyout firms’ portfolio companies ahead of anticipated IPOs.

The terms represent a more aggressive pitch than OpenAI’s initial approach. An earlier Reuters exclusive on March 16 first revealed that OpenAI was in advanced talks with TPG, Advent International, Bain Capital, and Brookfield Asset Management on a joint venture valued at approximately $10 billion, in which the PE firms would commit around $4 billion in exchange for preferred equity stakes. The follow-up reporting confirms OpenAI added the 17.5% floor return to its offer, along with early access to its newest AI models, to accelerate deal-closing.

The Deal Structure

Under the proposed arrangement, participating PE firms would receive preferred equity in the new venture — a senior class of ownership that gives investors priority returns over common shareholders and limits downside exposure. TPG is expected to serve as the anchor investor, committing the largest share of capital, with Advent, Bain Capital, and Brookfield participating as co-founders.

The 17.5% guaranteed floor is structured to make the pitch materially different from a standard equity investment. For buyout firms accustomed to targeting internal rates of return above 20%, a guaranteed floor reduces the risk profile while preserving upside if the venture generates revenue beyond that threshold. The early model access sweetener adds a competitive intelligence benefit on top of the financial terms — portfolio companies within the venture would get preferential access to OpenAI’s latest capabilities before they reach general availability.

The strategic goal is distribution at scale. Private equity firms collectively own or control hundreds of operating companies across sectors including healthcare, logistics, manufacturing, and financial services. A joint venture relationship converts those portfolio companies into a captive channel for OpenAI’s enterprise products, bypassing the slower, deal-by-deal enterprise sales cycle.

This move follows a string of enterprise distribution deals and major partnerships that OpenAI has struck over the past year, and comes after the company closed a $110 billion funding round in February 2026.

Anthropic’s Parallel Play

Anthropic is pursuing a nearly identical strategy but with different financial terms. According to The Information, Anthropic is in talks with Blackstone, Hellman & Friedman, and Permira for its own joint venture focused on deploying Claude models across portfolio companies. The Anthropic deal contemplates roughly $1 billion in PE equity stakes in the venture — substantially smaller than the $4 billion OpenAI is seeking — and does not include a guaranteed return.

The lack of a guaranteed floor in Anthropic’s offer is notable. Reuters reported that Anthropic may adjust its terms in response to OpenAI’s sweetened pitch, suggesting the 17.5% guarantee has already shifted negotiating dynamics. Whether Anthropic matches the offer or holds its terms likely depends on how urgently it needs capital versus distribution access.

Anthropic has recently gained ground in enterprise markets, particularly in developer tooling. Claude Code’s expansion into platforms like Slack reflects a distribution-first approach — building presence through the tools developers already use rather than through dedicated enterprise sales. Anthropic has also made deliberate choices on its business model that distinguish its positioning from OpenAI’s.

Both companies are structuring these ventures partly with IPO readiness in mind. Reuters noted that both OpenAI and Anthropic are eyeing public offerings as early as this year, and demonstrating strong enterprise distribution pipelines matters to prospective public market investors assessing growth durability.

Implications and Open Questions

The 17.5% guaranteed floor introduces financial risk that doesn’t exist in a standard equity relationship. If the joint venture generates returns below that threshold, OpenAI bears the cost of making up the difference — compressing margins that are already thin relative to traditional SaaS businesses. The competitive pressure in the enterprise AI space remains intense, and neither company has demonstrated stable profitability at scale.

The more consequential question is whether private equity firms actually add the distribution value both companies are pricing in. PE portfolio companies have IT departments, procurement processes, and vendor relationships of their own. A joint venture relationship with OpenAI or Anthropic does not automatically translate to broad deployment across hundreds of portfolio companies — it creates an opportunity, not a guarantee, for adoption.

No final agreements have been announced. Whether TPG or any other firm formally commits, and on what terms, will determine how much of this enterprise distribution thesis moves from narrative to executed deals. Disney’s $1 billion OpenAI partnership set a precedent for large-scale enterprise AI partnerships; the PE joint ventures, if closed, would extend that model across an entirely different class of buyers.
