Josh Kushner has long operated in the background of one of America’s most scrutinized families. While his older brother Jared drew headlines in politics, Josh built one of the sharpest venture capital firms of his generation. At 41, the founder and managing partner of Thrive Capital stands as a self-made force in tech investing, with a fortune built on early calls in Instagram, Spotify, Stripe, OpenAI and more. He is also co-founder and vice-chairman of Oscar Health, a minority owner in NBA teams, and recently linked to a record sports deal. Here is a clear look at the man behind the capital.

Early Life and Education
Joshua Kushner was born on June 12, 1985, in Livingston, New Jersey, into a prominent Jewish family. His father, Charles Kushner, built a major real-estate business; his mother is Seryl. He is the youngest of four siblings and the younger brother of Jared Kushner.
Kushner attended Harvard College, earning a bachelor’s degree in government in 2008. He spent a year in private equity at Goldman Sachs before returning to Harvard Business School for his MBA, which he completed in 2011. Even as a student he showed an entrepreneurial streak, co-founding the Brazilian social-gaming company Vostu and launching a campus pop-culture publication. Those early experiments set the tone for a career focused on technology rather than the family real-estate empire.
Building Thrive Capital and Key Investments
In 2009–2010, while still at business school, Kushner founded Thrive Capital with a modest first fund. The New York-based firm has since grown into a top-tier venture player managing roughly $25 billion in assets across multiple funds. Thrive is known for concentrated, high-conviction bets and a hands-on approach with founders.
Notable early and later investments include:
- Instagram (Series B, which quickly returned multiples after the Facebook acquisition)
- Spotify, Slack, GitHub, Stripe and Robinhood
- OpenAI, a defining recent position that helped cement Thrive’s status
- Other wins such as Warby Parker, Plaid and A24
Thrive raised successive larger funds, including a $5 billion vehicle in 2024, and has attracted high-profile limited partners. Kushner has kept the firm relatively lean while delivering strong returns, turning New York into a more credible alternative to Silicon Valley for certain founders.
He also co-founded Oscar Health in 2012, a technology-driven health insurer that went public in 2021. He remains vice-chairman. These dual roles—venture investor and company builder—distinguish him from pure financial players.
Personal Life and Family
Kushner married supermodel and entrepreneur Karlie Kloss in 2018 after several years of dating. The couple has three children: sons born in March 2021 and July 2023, and a daughter born in September 2025. They maintain homes that have included a Miami property purchased for $23.5 million and a penthouse in New York’s Puck Building, where Thrive is also headquartered.
Despite family political connections, Josh has largely stayed out of the spotlight and has been described as leaning more liberal in his personal views. He focuses publicly on business and family rather than partisan commentary.
Net Worth, Business Ventures, and Recent Moves
Forbes estimates Josh Kushner’s net worth at approximately $5.2 billion as of late 2025 and into 2026, making him the wealthiest member of the Kushner family. The bulk comes from his majority stake in Thrive Capital (valued in the billions after secondary sales that brought in investors including Bob Iger). Oscar Health and other holdings add to the total. He is widely regarded as self-made in the venture sense, separate from the family’s real-estate assets.
Beyond tech, Kushner holds minority stakes in professional sports, including the Miami Heat and earlier the Memphis Grizzlies. In August 2026 he and Bob Iger were reported to be acquiring the Los Angeles Lakers in a deal valued at more than $12 billion, a move that would expand his sports footprint dramatically if completed.

Conclusion
Josh Kushner proves that staying focused on building rather than broadcasting can produce extraordinary results. From a New Jersey upbringing and Harvard classrooms to backing some of the defining technology companies of the last 15 years, he has created lasting value through disciplined investing and quiet persistence.

In an era of loud personalities, Kushner’s low-key expertise continues to deliver outsized impact—making him one of the most consequential venture capitalists of his generation.
