OpenAI creates the capped-profit OpenAI LP

Background

OpenAI began as a nonprofit organisation. A nonprofit does not pay profits out to owners or shareholders, which made it hard to raise the large sums of money needed for expensive AI research by selling ownership. The 2019 change was an attempt to reconcile these two needs: a for-profit vehicle that could take in investment, under a limit set by the nonprofit's mission.

What happened

On 11 March 2019 OpenAI announced OpenAI LP. It described the company as a hybrid of a for-profit and a nonprofit, and called it a "capped-profit" company ^[1].

Returns for the first round of investors were capped at 100 times their investment. OpenAI said it expected the multiple to be lower in future rounds ^[1]. Profits above the cap go to the nonprofit. The caps for investors and employees were negotiated in advance for each limited partner ^[2].

TechCrunch illustrated the effect of the cap with an example: a $10 million investment would hit the cap only after generating $1 billion in returns ^[2].

Key details

Sam Altman left Y Combinator in March 2019 to become OpenAI's CEO full time ^[3]. The timing matched the announcement of the new structure.

The capped-profit structure stayed in place until OpenAI's October 2025 recapitalisation into a public benefit corporation ^[4]. A public benefit corporation is a company form that allows a business to pursue public-interest goals alongside profit, so the change marked a shift in the legal form of the organisation, not just in its investment terms.

Impact

The announcement made the trade-off between mission and investment explicit. The cap was the mechanism meant to keep profit from crowding out the nonprofit's purpose, and the sums in the TechCrunch example show what that limit meant in practice. Readers who compare the founding mission with this structure can see both the continuity and the change in how the organisation was financed.
