According to reports from Jin Shi data, informed sources revealed that Blackstone Group is increasing its investment in the artificial intelligence startup Anthropic, with its stake valued at approximately $1 billion based on current valuations. Informed sources stated that as part of the ongoing financing round for Anthropic, the world's largest alternative asset management company is injecting $200 million at a valuation of $350 billion. This investment by Blackstone is less than a year since its last participation in Anthropic's financing. Blackstone is also a supporter of OpenAI, and this investment places it among Anthropic's largest non-venture capital or non-sovereign fund investors. OpenAI has also been negotiating another record-breaking $100 billion financing, and both companies are taking steps to prepare for an initial public offering.
