Tech
Founder equity, public-market stakes, secondaries, foundations. The largest concentrated fortunes on the page.
Elon Musk
A fortune built almost entirely in equity — not cash — across five companies reshaping transportation, artificial intelligence, and space, our analysis puts Musk's net worth at $410 billion as of June 2026.
Larry Page
The Google co-founder's wealth, anchored almost entirely in Alphabet equity, crossed a threshold in 2026 that fewer than a handful of humans have ever approached.
Sergey Brin
Two and a half decades after co-founding the search engine that rewired commerce and culture, Brin holds a fortune built almost entirely on a single, spectacularly compounding bet.
Jeff Bezos
Founder of Amazon and one of the architects of modern e-commerce, now turning his attention to spaceflight, media, and long-horizon philanthropy.
Larry Ellison
Born in the Bronx and raised on borrowed ambition, Ellison has constructed a fortune so tightly bound to a single equity position that Oracle's stock chart functions as his personal balance sheet.
Michael Dell
A dorm-room gamble that became the defining American tech-founder story, Dell's wealth—anchored by equity concentration few billionaires would tolerate—has been supercharged by the AI infrastructure boom of 2025–2026.
Mark Zuckerberg
A fortune built almost entirely on a single equity position, Zuckerberg's $201 billion valuation is less a diversified wealth stack than a highly concentrated bet on the social internet — and, increasingly, on AI.
Jensen Huang
Three decades after co-founding Nvidia in a Denny's booth, Huang has built a fortune so tied to a single company's trajectory that it functions less like a diversified billionaire portfolio and more like a leveraged bet on the future of computing itself.
Bill Gates
Half a century after co-founding Microsoft in an Albuquerque garage, Gates commands a fortune now driven less by software royalties than by a quietly dominant investment machine called Cascade.
Peter Thiel
Palantir's post-election surge, a sprawling venture empire, and a legendary Facebook seed check have converged to make Thiel one of the most analytically interesting fortunes in technology.
Brian Chesky
The Airbnb co-founder's wealth is almost entirely a single-stock story — which makes it both remarkable in its concentration and vulnerable in ways most billionaire fortunes are not.
Reid Hoffman
Built on LinkedIn's bones and sharpened by two decades of venture bets, Hoffman's fortune is a masterclass in equity accumulation—and it isn't finished compounding.
Sam Altman
While Altman runs the most consequential AI company on earth, his $1.
Marc Andreessen
Three decades after co-creating the browser that commercialized the internet, Andreessen's fortune runs not on nostalgia but on the carried-interest engine of Silicon Valley's most influential venture firm.
