Josh Kushner's Wealth Triples in a Year and Negotiates to Buy the Lakers, Forbes Estimates Net Worth at Approximately $16.7 Billion
Forbes estimates that Josh Kushner, founder of Thrive Capital, has a net worth of approximately $16.7 billion, more than doubling from $5.2 billion a year ago, attributing this to positions in artificial intelligence and aerospace; he is negotiating with former Disney CEO Bob Iger to purchase the Los Angeles Lakers.
Thrive's assets under management were $23 billion in December 2024, with regulatory disclosures estimating around $50 billion by July 2026, and a letter to investors in August stating it has exceeded $65 billion. Forbes claims his personal wealth primarily comes from his stake in the company and the new valuation of Thrive Holdings, not yet accounting for the Lakers equity that has not been finalized.
After SpaceX went public in June, Thrive's stake reportedly rose to about $10 billion; this position began with early investments when the company's valuation was around $38 billion. Four days later, SpaceX announced a $60 billion acquisition of programming tools company Cursor, with Thrive's approximately 7% stake corresponding to about $4.2 billion. OpenAI remains a significant holding, with a valuation of around $852 billion in March, which has not yet realized comparable returns to SpaceX's IPO.
On August 12, Kushner and Iger reached an agreement to purchase the Lakers from Mark Walter at a valuation of $12.5 billion, setting a record for North American professional sports team transactions. Walter acquired control from the Buss family for $10 billion about 14 months ago. The two originally bid for an expansion team in Las Vegas but shifted their offer to the Lakers within days; the deal is still pending league approval and due diligence. On the same day, Thrive Holdings completed approximately $2 billion in financing, with investors including SoftBank, at a valuation of $12.5 billion, positioning itself as a company transforming service enterprises with artificial intelligence.
Kushner, born in 1985 in New Jersey, graduated from Harvard with an undergraduate degree and an MBA, founded Thrive around 2009, initially betting on Instagram, Stripe, Spotify, and co-founding the insurance company Oscar Health. Iger has been a partner at Thrive since 2022. The vehicle for the Lakers acquisition is reportedly the perpetual capital platform Thrive Eternal. The Buss family plans to retain about 15% and continue participating.
In market mechanics, the buyer is a venture capitalist converting unlisted tech positions into cultural assets, while the seller is a team ownership that has completed a record transfer within 14 months. The event is driven by the revaluation of wealth and the team offer occurring in the same week. Funds are flowing from OpenAI, SpaceX, and Cursor valuation accounts into sports franchises. Beneficiaries are buyers who can align the duration of thematic funds with arena cash flows and broadcasting rights, while current holders face pressure to increase their price by $2.5 billion within a year to sell.

Kushner has transformed his family's real estate background into early tech investments through his Harvard alumni network, then converted those investments into concentrated bets on OpenAI and SpaceX. His brother has taken a political route with Gulf sovereign funds, while he has pursued a path through Silicon Valley and cultural assets, with both sides turning their networks into balance sheets. Thrive started around 2010 with friends and Princeton endowment funds, with Instagram doubling in a week being the first public case study; over the next decade, it made 'following the right founders' a scalable main strategy. Iger joining as a partner effectively connects the tech portfolio to Hollywood and the league's directory.
The capital path is: private equity stakes expand, SpaceX's IPO provides a priceable exit, and Cursor's acquisition by the same issuer forms a secondary valuation, leading to a tripling of personal wealth alongside managed assets. The Lakers' offer appears in the same window as the Cursor valuation, not as a hobby purchase, but as a way to rewrite paper wealth into cash-flowing assets protected by league licenses. The Vegas expansion bid of around $7.5 billion was deemed insufficiently certain, leading to the purchase of an existing franchise with seventeen championships, exchanging a premium for certainty. Thrive Holdings simultaneously raised funds at a $12.5 billion valuation, attempting to extend the AI narrative from model labs to service companies.
Comparative cases include Silver Lake with Arsenal, Ballmer buying the Clippers, and Gulf funds acquiring Premier League teams. Professional sports are entering a phase of institutional pricing: teams are no longer just trophies for the wealthy but are beginning to be discounted based on broadcasting, venues, and global branding. Venture capital is in a phase of asset reallocation after an exit window opens. Kushner stands at the intersection of unlisted AI duration and listed franchise duration.
The essence is a switch in asset classes after capital concentration. Thematic investments bring future cash flows forward into net worth, while sports franchises convert net worth into license-protected pricing power. The mechanism is: when the marked price of a single fund's holdings jumps within months, the holder needs an asset that cannot be easily rewritten by the next valuation letter; league approval constitutes a new scarcity gate, with the volatility of tech positions partially exchanged for permanent seats at the arena.
