According to sources familiar with the matter, ChatGPT developer OpenAI is attracting private equity (PE) firms with more favorable terms than its competitor Anthropic, including a guaranteed minimum return of 17.5% and early access to its latest AI models. Both AI companies hope to raise new funds and accelerate the promotion of enterprise-grade AI products by establishing joint ventures with private equity firms. OpenAI has recently significantly increased its investment in the enterprise market, a field traditionally dominated by Anthropic. Through the joint venture structure, both sides aim to share the high upfront costs, alleviate financial pressure before going public, and rapidly deploy AI tools to hundreds of mature private companies under the PE firms' portfolios, thereby enhancing model utilization and user engagement. While some private equity firms remain cautious about the economic benefits and flexibility of such partnerships, others are in discussions with OpenAI and Anthropic to participate in the joint venture projects.
