Sound Ventures, the venture firm run by Madonna's manager Guy Oseary, holds an Anthropic stake worth about $7 billion at the company's $1.4 trillion target IPO valuation, after investing a total of $435 million. [Bloomberg](https://www.bloomberg.com/news/articles/2026-11-15/vc-firm-run-by-madonna-s-manager-has-7-billion-anthropic-stake) reported the stake and the valuation estimate on November 15, 2026. ## How Sound Ventures Backed Anthropic Dario Amodei, [Anthropic](https://akta.pro/company-profiles/0000002/anthropic)'s chief executive officer, visited Oseary's Beverly Hills home in 2023. He sat across from actor-turned-venture-capitalist Ashton Kutcher and Oseary, who owned the house. The group spent hours discussing AI safety, the race to build better artificial intelligence models and the vision for Anthropic, then an easily overlooked challenger to [OpenAI](https://akta.pro/company-profiles/0000008/openai). By the end of the meeting, Oseary, Kutcher and their team had decided to participate in the Claude maker's first institutionally led funding round through [Sound Ventures](https://akta.pro/company-profiles/0002mg8/sound-ventures). "I see him no different than one of the greatest musicians who's got all of these ideas in their minds, and they're going to go in the studio and make an incredible album," Oseary said in an interview from Beverly Hills. "This might be one of the greatest debut albums of all time." Sound Ventures owns roughly half a percent of the AI company, according to a person familiar with the matter. At Anthropic's current target IPO valuation of $1.4 trillion, that stake would be worth approximately $7 billion, according to Bloomberg estimates. The investment would mark a roughly 1,500% increase from the total $435 million Sound Ventures has poured into Anthropic over the years, according to people familiar with the matter. Sound Ventures and Anthropic declined to comment on returns. ## Anthropic's Funding and Revenue Records Anthropic's funding records on [akta.pro company records](https://akta.pro/company-data) list 26 funding rounds and total funding of $220.7 billion at the Series H stage, with the last round dated October 1, 2026.
