Josh Kushner Net Worth 2026: How the Thrive Founder Built $17.5 Billion

Quick answer

Josh Kushner's net worth is $17.5 billion, per the Bloomberg Billionaires Index on October 8, 2026 — his first-ever entry into the global top 500. Forbes puts him slightly lower at $16.7 billion (August 2026), after a year in which his fortune roughly tripled from about $5.4 billion. The wealth is overwhelmingly one thing: Thrive Capital, the venture firm he founded in 2009, which now manages more than $65 billion in assets.

The speed of the rise is what made 2026 his breakout year. A $1.77 trillion SpaceX IPO in June — Thrive was an early investor — a record $12.5 billion purchase of the Los Angeles Lakers with Bob Iger in August, and Bloomberg's estimate of more than $6 billion in carried interest since 2010 combined to push Kushner from a quiet venture capitalist into one of the richest people on the planet. For the full backstory, see how he built the fortune, the companies behind it, and how he compares to co-buyer Bob Iger.

How the $17.5 billion breaks down

Kushner discloses nothing about his personal balance sheet — a spokesperson declined to comment on Bloomberg's valuation — so every figure here is an estimate built from reported pieces. Bloomberg's math starts with Thrive Capital itself, which it values at roughly $23 billion; Kushner's personal stake in that enterprise value is the single largest component of his fortune. On top of that sits his share of carried interest — the firm's cut of investment profits — estimated at more than $6 billion since 2010, most of it earned in the last three years.

The sports portfolio adds a visible, trophy layer. The Lakers deal at a $12.5 billion valuation implies about $1.875 billion for the 15% stake Kushner needs to become team governor under NBA rules — and his investor deck, reviewed by the Wall Street Journal, pitches the franchise reaching $30 billion within a decade, with an upside case of $62 billion. Earlier sports bets included a 2.5% stake in the Memphis Grizzlies in 2019, a Miami Heat holding, and a minority investment in baseball's San Francisco Giants.

One caution the data deserves: this is an estimate of net worth, not a confirmed cash total. Thrive's holdings are private, and Kushner's personal ownership percentages have never been publicly confirmed. Read the $17.5 billion as Bloomberg's assessment of the empire's value to its founder — which is how every billionaire index works.

The Thrive engine: from $15B to $65B in three years

Thrive Capital is the machine that did it. Founded by Kushner in 2009, the firm spent its first decade as a respected but conventional venture investor — early money in Instagram, Spotify, and Stripe — before exploding in the last three years from about $15 billion to more than $65 billion in assets under management. More than half of that growth came from investment gains, not new fundraising, according to an August letter Kushner sent to investors.

The portfolio reads like a greatest-hits of the last fifteen years of tech: early investor in OpenAI, stakes in SpaceX and Stripe, an investment in AI coding company Cursor before SpaceX acquired it at a $60 billion valuation. More recently Thrive pushed into public markets, buying into Amazon and Shopify, and into operating businesses through Thrive Holdings — which has raised more than $2 billion and acquired 70-plus companies in accounting, IT services and other sectors it plans to transform with AI.

The newest engine is Thrive Eternal, a strategy focused on assets Kushner believes hold or grow their value as AI reshapes the economy — long-duration trophy assets. It financed the Lakers acquisition and holds the Giants minority stake. The logic, laid out in Kushner's investor letter, is that the scarcest assets of the AI era are not startups but franchises, platforms and brands that cannot be replicated.

The $12.5 billion Lakers deal

In August 2026, Kushner and former Disney CEO Bob Iger agreed to buy the Los Angeles Lakers from Mark Walter for a record $12.5 billion — the largest price ever paid for a US professional sports franchise. ESPN first reported the deal on August 12. Walter had bought control from the Buss family at a roughly $10 billion valuation only about 14 months earlier, in October 2025, making this the second record Lakers sale in just over a year.

"As lifelong NBA fans, we are deeply honored for the opportunity to become stewards of the Los Angeles Lakers," Kushner and Iger said in a joint statement, promising to build on the foundation of Jerry and Jeanie Buss. The deal's ambition is bigger than basketball: the buyer group's investor presentation projects the Lakers at $30 billion in ten years, assuming TV and streaming rights double, with a blue-sky case of $62 billion. NBA commissioner Adam Silver publicly admitted the quick resale caught him by surprise.

The transaction has not been quiet. Five of Jeanie Buss's siblings voted to exercise the family trust's tag-along rights and sell their remaining 17.82% stake for about $2.2 billion, which would end Jeanie's tenure as team governor — NBA rules require a governor to hold at least 15%. Jeanie filed a petition in August to block the sale. Whatever the outcome, Kushner's group is positioned to install him as governor.

How his fortune tripled in twelve months

A year ago, Kushner was worth roughly $5.4 billion — rich, but not top-500 rich. Three forces tripled that in twelve months. First, SpaceX's $1.77 trillion IPO in June 2026, the largest public offering in history, which repriced Thrive's early stake and, per Bloomberg, provided "another major boost" to the portfolio. Second, the surge in Thrive's own value to roughly $23 billion as AUM crossed $65 billion, with carried interest alone topping $6 billion. Third, the visibility premium of 2026's deal spree — the Lakers, the Giants, the collapsed FIFA investment — which cemented Thrive's rebrand from VC firm to diversified investment empire.

The Forbes and Bloomberg numbers bracket the same story: $16.7 billion (Forbes, August 2026) to $17.5 billion (Bloomberg, October 2026). The $800 million gap between the two is normal — the indexes use different valuation dates and methods — and both agree on the trajectory: up roughly 200% in a year.

Early bets that built the base

Before the empire, there was a string of bets that look obvious only in hindsight. Thrive was an early investor in Instagram before its $1 billion sale to Facebook, backed Spotify and Stripe in their growth years, and got into OpenAI early — a position that has compounded enormously as AI valuations exploded. Thrive participated in OpenAI's March 2026 funding round, which closed with $122 billion in committed capital at a $852 billion post-money valuation.

The through-line is Kushner's willingness to hold. Where many VCs sell into IPOs, Thrive Eternal's whole premise is owning trophy assets for the long term — which is why a venture firm now owns pieces of a baseball team and, imminently, a basketball dynasty. The early exits funded the firm's growth; the refusal to exit is what's compounding it.

Beyond Thrive: Oscar Health, Cadre and the portfolio

Kushner is not a one-company founder. He co-founded Oscar Health, the tech-driven health insurer, where he serves as vice-chairman; co-founded real estate investment platform Cadre; and co-founded social games developer Vostu back in 2006, which scaled back after a copyright lawsuit from a competitor. Straight out of Harvard he founded Unithrive, a peer-to-peer student lending startup, and spent a year in Goldman Sachs' private equity arm working on distressed debt.

The man behind the money: family and bio

Joshua Kushner was born June 12, 1985, in Livingston, New Jersey, the youngest son of real estate developer Charles Kushner and Seryl Kushner. He graduated from Harvard College in 2008 and Harvard Business School in 2011 — and he started Thrive while still a student, a fact that makes the firm's scale even more striking. His older brother is Jared Kushner, the investor and former White House senior adviser married to Ivanka Trump; Josh has been described as a lifelong Democrat, a contrast that has occasionally made headlines.

In 2018 he married model and entrepreneur Karlie Kloss; they have three children. Unlike many new sports owners, Kushner has spent his career avoiding the spotlight — Bloomberg noted his "long cultivated, under-the-radar profile." The Lakers deal and the top-500 debut make that profile much harder to maintain.

What comes next: Thrive Eternal and the $30 billion plan

The next chapter is already being written. Thrive Holdings continues rolling up service businesses with its $2 billion-plus war chest, and Thrive Eternal is hunting more trophy assets — a proposed FIFA investment collapsed within days after opposition from regional football groups, with UEFA reportedly exploring legal action (without accusing Thrive or Kushner of wrongdoing). The Lakers investor deck's $30 billion target, and its $62 billion upside case, will be the scoreboard everyone watches.

If even half of that plays out, the $17.5 billion figure that put Kushner in the top 500 will look like the beginning, not the peak. The story of how he made it suggests he has never been interested in selling early — and at 41, he has decades of compounding ahead.
