OpenAI is in talks to invest up to $1.5 billion in a new joint venture with private equity firms, the Financial Times has reported. The ChatGPT maker would initially contribute $500 million into the entity, known internally as DeployCo — a Delaware-registered LLC valued at around $10 billion — with an option to add a further $1 billion later; backers including TPG, Bain Capital, Advent International, Brookfield, and Goanna Capital are expected to invest an additional $4 billion. The deal, which would guarantee private equity investors an annual return of 17.5% over five years, is designed to accelerate the rollout of OpenAI's workplace tools and marks a significant push into the enterprise software market, where rival Anthropic currently holds a stronger foothold among corporate clients.
