Anthropic is closing a joint venture that will pool about $1.5 billion from major Wall Street investors, including Blackstone, Goldman Sachs, and Hellman & Friedman. The partnership will target private‑equity‑backed firms, offering them AI tools developed by Anthropic’s Claude platform. Investors each plan to contribute roughly $300 million.

The deal, slated for a public announcement by Monday, follows Anthropic’s rapid growth after raising $600 million in a Series D earlier this year. By channeling capital through a dedicated venture, the firm hopes to accelerate its product roadmap while giving investors a direct stake in the expanding AI services market.

Blackstone, a leading asset manager, and Goldman Sachs, a global brokerage, each bring not only capital but also deep industry networks that can help Anthropic reach a broader client base. Hellman & Friedman’s involvement signals confidence from seasoned private‑equity players in the AI sector’s upside.

If finalized, the joint venture could position Anthropic as a key AI supplier for private‑equity portfolios, potentially reshaping how tech investments are deployed. The combined $1.5 billion stake also signals that Wall Street is increasingly willing to back AI infrastructure as a core growth engine.
