Josh Kushner’s Net Worth Tripled to $16.7B on OpenAI and SpaceX Bets

Josh Kushner's net worth jumped from $5.2 billion to $16.7 billion over the past year, according to Forbes, driven almost entirely by his venture firm Thrive Capital. Thrive's assets under management grew from $23 billion in December 2024 to more than $65 billion by August 2025, fuelled by a reported $10 billion stake in SpaceX after its June IPO, a $4.2 billion stake in AI coding tool Cursor after SpaceX acquired it, and a position in OpenAI, last valued at $852 billion in March 2025. On the same August day the Lakers sale was announced, Kushner also closed a $2 billion raise for a new AI services company.

Josh Kushner is 41 years old and runs Thrive Capital, the New York firm he founded in 2010 at age 25 with a $5 million seed from Joel Cutler, co-founder of General Catalyst. Kushner joined straight out of Harvard Business School after a year at Goldman Sachs’ private equity desk.

Thrive’s early record is notable. It invested in Instagram at a $500 million valuation in 2012; Facebook acquired Instagram just days later for $1 billion. The firm has since backed Instacart, Nubank, Robinhood, Spotify, Cursor, and SpaceX, among others. Several remain private at large valuations: Anduril ($61 billion, May 2025), Databricks ($190 billion, August 2025), and Stripe ($159 billion, February 2025).

The biggest catalyst this year was SpaceX going public in June. That pushed Thrive’s stake to a reported $10 billion. Four days after the IPO, SpaceX announced a $60 billion acquisition of Cursor, an AI coding assistant, valuing Thrive’s 7% position in Cursor at $4.2 billion. Both windfalls landed within the same week.

Separately, Kushner formed Thrive Holdings in 2025. The entity buys services businesses and rebuilds them around AI tools. On August 12, it closed a $2 billion raise from investors including SoftBank, at a $12.5 billion valuation.

That same day, news broke that Kushner and former Disney CEO Bob Iger had agreed to buy the Los Angeles Lakers for a record $12.5 billion. The deal faces at least one complication: a lawyer for Jeanie Buss, the team’s controlling governor, stated she had not agreed with her five siblings to sell their collective 17.8% stake. Kushner also holds a small stake in the Miami Heat, estimated at $80 million, which he must sell before any Lakers acquisition can close.

In an August letter to Thrive investors, obtained by Bloomberg, Kushner also floated a potential sale of a small stake in Thrive Capital itself, similar in size to the 3% stake sold in 2021 and later flipped to original shareholders plus a small group of new institutional partners.

Why it matters

The Thrive story is a clean case study in concentrated, high-conviction bets on private companies before they mature. Thrive held positions in OpenAI, SpaceX, and Cursor simultaneously. When SpaceX listed and then acquired Cursor in the same week, the gains compounded in a way that diversified funds rarely see.

Thrive Holdings, the AI services rollup, is a different kind of bet. It signals that some investors see more value in applying AI to existing service businesses than in building new AI infrastructure from scratch. Raising $2 billion at a $12.5 billion valuation before the rollup has had time to prove results suggests SoftBank and other backers agree, or at least are willing to pay for the option.

For businesses watching how AI investment actually flows, this is a useful signal. The money is not only going to foundation model labs. It is also going to operators who can acquire service firms and automate their workflows, which is a playbook any mid-sized agency or services company should be aware of. If you are curious how AI integration looks at a business level rather than a fund level, the structure of Thrive Holdings is a decent reference point.

Our take

Thrive’s AUM nearly tripling in eight months is striking, but most of that growth is mark-to-market, not realised cash. SpaceX’s public valuation and Cursor’s acquisition price are real events, but until Thrive sells shares, the numbers are paper gains. The $65 billion AUM figure came from Kushner’s own investor letter, written at a moment when he was also floating a stake sale in the firm. Investors should read that in context.

That said, Thrive’s track record over 16 years and 10 flagship funds is genuine. The Instagram entry in 2012, the early OpenAI position, and the Cursor stake are not lucky flukes. The pattern is consistent: get in early, hold through volatility, and wait for a liquidity event. Most funds do not have the discipline or the LP patience to do that.

The Thrive Holdings angle is worth watching separately from the VC fund. Rolling up services businesses and rebuilding them on AI is a credible strategy, but a $12.5 billion valuation at the start of that process is an aggressive ask. Execution risk in services is real. SoftBank has backed expensive rollups before with mixed results.

For operators thinking about their own businesses, the broader pattern here is worth noting. We have written before about the real costs of deploying AI agents inside companies. Thrive Holdings is betting those costs are manageable at scale. Whether that plays out will tell us a lot about where the AI-in-services wave actually lands.

What to do about it

1. Watch the Thrive Holdings rollup closely over the next 12 months. If it shows margin improvement in acquired businesses, that is a proof point for AI-driven services transformation worth studying.
2. Note which sectors Thrive Holdings targets. Early signals suggest professional services and operations-heavy businesses. If your sector appears, expect acquisition interest and increased competition from AI-optimised operators.
3. If you run a services business, audit where your workflows are still manual. Firms that cannot show automation traction will be at a disadvantage if and when acquirers with AI playbooks come shopping. Consider a workflow automation review now rather than reactively.
4. Track OpenAI’s IPO timeline. Thrive holds a stake in OpenAI, last valued at $852 billion. When OpenAI lists, Thrive’s AUM and Kushner’s net worth will move again, and so will the broader AI investment narrative.

The Thrive story is mostly about patience and entry price. For everyone else, the practical takeaway is simpler: the money flowing into AI services rollups means the window for service businesses to automate on their own terms is narrowing.
