Josh Kushner Companies: Every Business in the $17.5B Empire

Quick answer

Josh Kushner's business empire has four pillars. Thrive Capital — the venture firm he founded in 2009, now managing more than $65 billion — is the core. Oscar Health, the tech-driven insurer he co-founded, where he serves as vice-chairman. Cadre, the real estate investment platform he co-founded. And, as of August 2026, the Los Angeles Lakers, which he agreed to buy with Bob Iger for a record $12.5 billion, plus a minority stake in baseball's San Francisco Giants. Together they underpin a personal fortune Bloomberg pegs at $17.5B.

Past ventures include social games developer Vostu (scaled back after a copyright lawsuit), student-lending startup Unithrive, and sports holdings in the Miami Heat and a 2.5% Memphis Grizzlies stake. For the fortune these companies built, see his $17.5 billion net worth and how he made his money.

Thrive Capital: the $65 billion core

Founded by Kushner in 2009, Thrive Capital is the company everything else orbits. What began as a student-run venture fund is now an investment empire managing more than $65 billion — triple the ~$15 billion it held three years ago — with Bloomberg valuing the firm itself at roughly $23 billion. Kushner remains founder and managing partner, and his ownership of the firm is the largest component of his $17.5 billion fortune.

Thrive's investment record is the resume: early money in Instagram, Spotify and Stripe, an early position in OpenAI, stakes in SpaceX and Stripe, AI coding company Cursor before its $60 billion acquisition, and recent public-market bets on Amazon and Shopify. More than half of the AUM growth came from investment gains, per Kushner's August investor letter.

Thrive Eternal & Thrive Holdings: the expansion vehicles

Two newer vehicles show where Kushner is taking the empire. Thrive Eternal buys long-duration trophy assets expected to hold value through the AI transition — it financed the $12.5 billion Lakers acquisition and holds the Giants minority stake. Thrive Holdings takes the opposite approach: it has raised more than $2 billion and acquired 70-plus operating companies in accounting, IT services and other sectors, aiming to transform them with AI.

Together they mark Thrive's evolution from venture fund to diversified investment company — public equities, operating businesses, and sports franchises under one roof.

Oscar Health: the health-tech bet

Kushner co-founded Oscar Health, the technology-focused health insurance company, and serves as its vice-chairman. Oscar was his second founding identity beyond venture — an operating company in one of America's most complex industries, built on the thesis that consumer tech could fix health insurance. It gave Kushner a public-company track record and a second source of wealth independent of Thrive's funds.

The Oscar bet also reveals Kushner's pattern as a founder: pick an industry everyone agrees is broken, then attack it with software and design. Health insurance was the least consumer-friendly business in America; Oscar's pitch was telemedicine-first care, transparent pricing, and an app members might actually open. Whether or not the model fully delivered, the instinct — apply the venture playbook to an old industry — is the same one now driving Thrive Holdings' acquisition of 70-plus service businesses.

Cadre: real estate, the tech way

Cadre, the real estate investment platform Kushner co-founded, applied the Thrive playbook — software and data — to commercial property investing. It let the Kushner scion touch the family industry (his father Charles built a real estate fortune) on his own terms: as a technology investor, not a landlord. Cadre opened institutional-quality real estate deals to a broader investor base through its online marketplace.

Cadre's significance is easy to miss but real: it was Kushner's first attempt to productize access to an asset class — the same instinct behind Thrive Eternal's trophy assets and Thrive Holdings' roll-ups. Where Thrive the VC fund served limited partners, Cadre served the thesis that technology could widen who gets to own productive assets. In hindsight, it was a rehearsal for the empire's current shape: not just picking winners, but building the platforms that own them.

The sports portfolio: Lakers, Giants, and past NBA stakes

The most visible addition is the Los Angeles Lakers: Kushner and Bob Iger's $12.5 billion agreement in August 2026, the largest price ever for a US sports franchise, buying from Mark Walter (who had paid ~$10 billion fourteen months earlier). The buyer group's investor deck, reviewed by the Wall Street Journal, pitches the Lakers at $30 billion within a decade — upside case $62 billion. Kushner is expected to become team governor, requiring at least 15% ownership (~$1.875 billion at the deal price).

He is no stranger to sports ownership: a minority stake in the San Francisco Giants (via Thrive Eternal), a previous holding in the Miami Heat, and a 2.5% stake in the Memphis Grizzlies acquired in 2019. The Lakers deal dwarfs them all — and makes the sports portfolio a genuine third pillar of the empire.

Past ventures: Vostu, Unithrive and the early lessons

Not everything worked. Vostu, the social games developer he co-founded in 2006 targeting Latin America, laid off most employees in 2013 and scaled back sharply after a copyright lawsuit from a competitor. Unithrive, his peer-to-peer student lending startup inspired by Kiva, never scaled. Even the college publication Scene, where he was founding executive editor, was "badly received by critics."

The failures matter because of what they taught: Kushner's winners — Thrive, Oscar — are the ones where he paired early entry with relentless holding. Vostu's lesson, in particular, was about moats: software without one gets copied.

There is a second lesson in the graveyard: timing beats ideas. Unithrive's peer-to-peer student lending was a sound concept years before fintech made it mainstream; Vostu chased social gaming just as the market consolidated around giants. Kushner's later career is the correction — Thrive doesn't try to win categories, it buys into the winners early and holds. The student who started companies in his dorm became the investor who lets other founders take the operating risk.

What's next for the empire

The trajectory is clear: more trophy assets, more operating companies, more AI transformation. Thrive Holdings keeps acquiring with its $2 billion-plus war chest. Thrive Eternal hunts the next Lakers — a proposed FIFA investment collapsed within days, but the appetite is public. And the core VC engine keeps compounding on OpenAI, SpaceX and the public-market book.

At 41, Kushner has built what most founders never do: four companies and a sports franchise, all still growing. The $17.5 billion net worth is the scoreboard — see how it stacks up against his Lakers co-buyer Bob Iger.

The through-line across every company is the same: find the compounding asset, buy it early, and refuse to sell. Thrive's venture portfolio, Oscar's insurance book, Cadre's property marketplace, the Lakers' media rights — each is a bet that the scarcest things in the AI era are franchises that cannot be replicated. If that thesis is right, the empire's next decade will be measured not in funds raised but in assets that never come back to market.
