Joshua Kushner has quietly become one of the most successful venture capitalists of his generation. While his brother Jared often dominates headlines, Josh built his own fortune the old-fashioned way—by spotting transformative companies early and backing them with conviction. As of August 2026, Forbes estimates his net worth at $5.2 billion, placing him among the world’s top 800 richest people. His recent role in the record $12.5 billion purchase of the Los Angeles Lakers alongside Bob Iger has only amplified interest in how he got there.

Early Life and Family Foundations
Born on June 12, 1985, in Livingston, New Jersey, Joshua grew up in a family already steeped in real estate success. His father, Charles Kushner, built Kushner Companies into a major New York-area developer. Joshua attended Harvard University, earning both a bachelor’s degree and an MBA from Harvard Business School. Those years shaped his analytical approach and network. Unlike many heirs who simply manage family assets, he chose a different path, launching his own firm in 2009 while still in his mid-20s. The family wealth provided a safety net, but the bulk of his current fortune comes from his own deals.
Building Thrive Capital Into a Powerhouse
Thrive Capital started small and scaled aggressively. Early funds were modest, but performance and reputation allowed rapid growth. The firm has raised billions across multiple vehicles, with later funds reaching several billion dollars each. Key early wins included a major stake in Instagram’s Series B round—just before Facebook acquired the company—and investments in Spotify, Stripe, and later OpenAI.
Thrive’s approach mixes early-stage bets with later growth capital. By 2023 the firm itself was valued at roughly $5.3 billion in a secondary sale that included investors such as Bob Iger. Joshua is widely believed to retain a majority stake, often cited in the 50–66% range. That ownership, combined with carried interest from successful funds, forms the core of his $5.2 billion net worth. The firm now manages tens of billions in assets and continues expanding into adjacent areas.
Sports Stakes and Broader Portfolio
Beyond pure tech, Joshua has diversified into sports and healthcare. He co-founded Oscar Health, a technology-driven insurance company that went public in 2021; he remains vice chairman and holds a meaningful stake. On the sports side, he previously owned minority pieces of the Memphis Grizzlies and Miami Heat. In 2026 he and Iger agreed to acquire controlling interest in the Lakers at a $12.5 billion valuation—the highest price ever paid for a North American sports franchise. He also holds a minority interest in the San Francisco Giants through a Thrive-related vehicle. These moves show a clear strategy: treat cultural and sports assets as long-term equity plays, much like high-growth tech.

They purchased a distinctive Malibu home known as the “Wave House” for about $29.5 million in 2024 and own property in Miami Beach. Despite the wealth, Joshua is often described as focused and understated in business circles. He stays closely involved in Thrive’s major decisions and continues to back ambitious founders.
