OpenAI and Anthropic's Funding Frenzy

OpenAI and Anthropic unveiled parallel private equity tie-ups on the same day, each designed to push their models into thousands of mid-market companies that neither lab can reach on its own. OpenAI has finalized a $10 billion joint venture called the Deployment Company alongside TPG, Brookfield, Bain and Advent, while Anthropic countered with a $1.5 billion arrangement involving Blackstone, Goldman Sachs, Hellman & Friedman and General Atlantic.

The structure is unusual. Rather than sign individual enterprise contracts, the two labs are buying distribution wholesale through firms that already own hundreds of portfolio businesses. "TPG for just as an example, they own over or they have stakes in or they own over 2000 companies," Jaeden Schafer said on the podcast, framing each of those holdings as a customer OpenAI would otherwise have to chase one cold call at a time.

The commercial logic flows from where AI revenue actually sits today. OpenAI has millions of consumer subscribers paying $20 a month, a base that does not throw off enterprise-grade margins. Anthropic, by contrast, has a narrower set of large accounts spending heavily on Claude. Both want the middle tier — the companies too small to negotiate Microsoft- or Google-scale deals but large enough to spend serious budget on tokens.

Key facts

  • 01OpenAI has finalized a $10 billion joint venture called the Deployment Company with TPG, Brookfield, Bain and Advent, contributing $1.5 billion of its own capital.
  • 02Anthropic announced a $1.5 billion venture with Blackstone, Goldman Sachs, Hellman & Friedman and General Atlantic targeting the same mid-market push.
  • 03OpenAI is guaranteeing its private equity partners a 17.5% annual return on capital deployed into the new venture.
  • 04Both companies are positioning the deals ahead of potential IPOs that could come this fall, with TPG alone holding stakes in more than 2,000 portfolio companies.

Inside the Deployment Company, the founding private equity firms are putting in roughly $4 billion across 15-plus participants, OpenAI is contributing $1.5 billion, and the lab retains the option to add another billion. The vehicle will then sell into the PE firms' own portfolio companies, with the sponsors effectively dictating the standard. As Jaeden Schafer put it on the show, the private equity owners can tell their holdings, "hey, look, we just partnered with opening I you guys are all using open, you know, open AI now instead of Anthropic or whatever else you were using before."

Both labs are also borrowing Palantir's forward-deployed engineer playbook. OpenAI and Anthropic plan to embed developers inside customer organizations to audit code, manage rollout and drive consumption — a sticky arrangement that matters because both companies are paid largely on tokens used. Software that sits unused does not generate revenue, so the labs are buying the change-management muscle that mid-market firms typically lack.

The most striking term has gone largely unremarked: OpenAI is guaranteeing its private equity partners a fixed return on the capital they put in. "OpenAI is actually guaranteeing their private equity partners a 17.5% annual return," Schafer said, noting that the payout is meant to come out of token spend and AI deployments inside the sponsors' portfolio companies. The structure shifts deployment risk from the PE firms to OpenAI itself.

It is not entirely new territory for OpenAI. The company's original Microsoft deal routed its workloads onto Azure and gave Microsoft a royalty stream on OpenAI revenue, a template the lab is now generalizing into a standalone subsidiary. Spinning the activity into a separate Deployment Company also gives OpenAI a cleaner, faster-growing revenue line to point at when bankers start modelling an IPO.

That timing is the subtext for both announcements. Schafer argued the labs are racing to lock in mid-market logos before going public, with OpenAI and Anthropic both eyeing listings as soon as this fall. Adding tens of thousands of operating companies via private equity sponsors is a quicker way to thicken the enterprise revenue story than building out a traditional sales force, and it leaves rivals — including each other — with fewer untouched accounts to win once the IPO roadshows begin.
