Sound Ventures, a venture capital fund co-founded by Jerusalem-born Guy Oseary and actor Ashton Kutcher, stands to be a major beneficiary of the upcoming initial public offering (IPO) of Anthropic, the developer of the AI model Claude. The fund is estimated to hold approximately 0.5% of Anthropic's shares. With a fully diluted valuation of Anthropic potentially reaching $1.4 trillion at the upper end of its price range, Oseary's stake could be worth around $7 billion. Sound Ventures initially invested about $435 million in the AI company.
This valuation would represent a roughly 16-fold increase on their investment, yielding an estimated paper profit of $6.6 billion. Sound Ventures has declined to comment on these figures. Oseary, who moved from Jerusalem to Los Angeles as a child and has managed Madonna for many years, co-founded A-Grade Investments with Kutcher and billionaire Ron Burkle in 2010. That earlier fund backed early-stage investments in companies like Uber, Airbnb, and Spotify.
Oseary and Kutcher established Sound Ventures in 2015. In May 2023, Sound Ventures launched a $240 million fund focused on artificial intelligence, with initial investments including OpenAI, Anthropic, and Stability AI. The fund also participated in Anthropic's $450 million Series C round that same month, reportedly investing around $35 million initially, followed by an additional $400 million.
Since then, Anthropic's valuation has surged from $61.5 billion in March 2025 to $965 billion by May 2026. The company reported revenues of $41 million in 2023 and $33.2 billion for the first nine months of 2026. In addition to the fund's investments, Oseary is entitled to a share of the success fees, typically at least 20% of profits in the venture capital industry. With profits estimated at $6.6 billion, managing partners could receive around $1.3 billion. While Sound Ventures does not disclose profit distribution details, the portal Bizportal estimates Oseary's personal share could be in the hundreds of millions of dollars.
