Quick answer
Adam Foroughi is the richer ad-tech billionaire — and it is not close. Foroughi, the AppLovin co-founder and CEO, is worth $11.6 billion per Bloomberg (September 2026). Jeff Green, the founder and CEO of The Trade Desk, sits at roughly $4.2 billion in recent estimates — a fortune that has more than halved as his company's stock collapsed about 68% year-to-date in 2026. Both men built independent advertising technology companies to fight the Google-Meta duopoly. Both are getting crushed by the market in 2026. But Foroughi's empire is roughly three times the size of Green's — and their paths to the top could not be more different.

Foroughi: the bootstrapper who wouldn't dilute
Foroughi's fortune is a monument to ownership concentration. Born in 1980 in Tehran, he fled Iran with his family during the Iran-Iraq War, grew up in Southern California, and graduated from UC Berkeley in 2001 before working as a derivatives trader. After two modest ad-tech startups (Lifestreet Media, Social Hour), he co-founded AppLovin in 2012 — and when venture capitalists rejected the pitch, he bootstrapped instead, raising a $280 million leveraged loan in 2018 rather than diluting, alongside a $400 million KKR investment.
The payoff came with AXON 2.0, AppLovin's AI ad engine, which drove a ~519% stock surge in 2024 and carried Foroughi to $27.3 billion in December 2025. Roughly 99% of his $11.6 billion net worth is that one ~11% stake — the most concentrated fortune in big tech. He barely sells: about $1.9 million in insider sales in March 2026, a rounding error.
Green: the programmatic pioneer from Microsoft
Jeff Green's road ran through the establishment. Born in 1977 (age 49), a USC marketing communications graduate, he founded the ad exchange AdECN — acquired by Microsoft in 2007 — then advised strategy for Microsoft's Online Services division, overseeing the monetization of Facebook ads, MSNBC, and Hotmail. In 2009 he co-founded The Trade Desk in Ventura, California with fellow ex-Microsoft employee Dave Pickles, raising $120 million in venture capital along the way.
The Trade Desk operates a demand-side platform (DSP) — software that lets advertisers buy programmatic ads across the open internet, deliberately independent of Google's and Meta's walled gardens. Its September 2016 IPO was hailed as one of the decade's best, with the stock trading at nearly 14 times the IPO price within three years. By 2020 the company was worth $28.6 billion, and Forbes estimated Green's wealth at $6 billion in 2023. Green has also pledged to give away 90% of his wealth through his Dataphilanthropy foundation — a philanthropic commitment Foroughi has never made.
Different sides of the same war
The strategic contrast is the interesting part. AppLovin is supply-side and mobile-first: it helps app developers monetize, with AXON deciding which ad to show 1.4 billion daily users. The Trade Desk is demand-side and open-internet: it helps brands buy ads programmatically across websites, streaming, and now connected TV — Green announced Ventura, The Trade Desk's own TV operating system, in November 2024.
Both positioned themselves as the independent alternative to the duopoly. Foroughi competes with Meta and Alphabet in mobile; Green argues the open internet needs an independent broker rather than another walled garden. In 2024–2025 both stocks were AI darlings. In 2026 both are cautionary tales.
2026: the year both fortunes cracked
Nobody in ad tech escaped 2026. AppLovin's 53.8% year-to-date fall — the third-worst in the S&P 500 — cost Foroughi $13.5 billion, the sixth-largest dollar loss of any billionaire. The Trade Desk's fall was steeper in percentage terms: down roughly 68% year-to-date, with the market cap collapsing to about $5.6 billion from a 52-week high near $56 a share.
Green's crash had company-specific accelerants: reported technical problems and delayed adoption of Kokai, The Trade Desk's AI platform, plus class-action lawsuits alleging misstatements about its performance — with reports that Green and former executives sold over $465 million in stock during the class period. Green responded with conviction: a reported $150 million personal purchase of Trade Desk shares, betting his own money on the recovery. Foroughi's response was the opposite: hold everything, sell nothing, wait.
Pay packages vs ownership: the real scoreboard
On headline pay, Green wins by a mile: his $834 million 2022 package (mostly stock options) was one of the largest in corporate history, versus Foroughi's $83.4 million peak year in 2023 (which made him only the 8th highest-paid US CEO). But pay is the small number for both men. Foroughi's ~11% AppLovin stake is worth $11.6 billion — about 14 times Green's entire pay package. Green's single-digit-percentage Trade Desk holding, at a ~$5.6 billion market cap, is worth a fraction of Foroughi's position.
| Wealth component | Foroughi | Green |
|---|---|---|
| Company stake value | ~$11.6B (~11% of AppLovin) | ~$4B (single-digit % of TTD) |
| Peak annual pay | $83.4M (2023) | $834M (2022) |
| 2025–2026 cash selling | ~$1.9M (Mar 2026) | Buying: ~$150M personal purchase |
| Philanthropy pledge | None public | 90% via Dataphilanthropy |
The scoreboard, then: Foroughi is roughly 3x richer, holds a far larger slice of a far larger company, and has never meaningfully sold. Green took the bigger pay package, raised venture capital instead of bootstrapping, and is now publicly buying the dip in his own stock. Two founders, two philosophies, one brutal year.
Who wins from here?
The bull case for Foroughi is scale: AppLovin's $5.48 billion in trailing revenue, 80%+ margins, and the push of AXON into e-commerce advertising — a market many times larger than mobile gaming, which AppLovin exited via the $400 million Tripledot sale in 2025. The bull case for Green is independence: if the open internet keeps growing at a ~23% compound rate through 2030, as analysts project, The Trade Desk's DSP remains the purest play on it — and at a ~$5.6 billion market cap, the bar for a rebound is low.
For now, the verdict is arithmetic: $11.6 billion beats ~$4.2 billion, and an 11% stake in a ~$100 billion company beats a smaller slice of a $5.6 billion one. But both fortunes are single-stock bets in an industry being rewritten by AI — and 2026 proved how fast the scoreboard can change. Green is betting $150 million of his own money that the open internet wins; Foroughi is betting his entire fortune, untouched and unsold, that AXON's edge is real. Two founders, two philosophies, one brutal year — and the next twelve months will decide which conviction was wisdom and which was stubbornness. For the full Foroughi fortune breakdown, how he made it, and the companies he owns, those are the deep dives.
Frequently asked questions
Who is richer: Adam Foroughi or Jeff Green?
Adam Foroughi is richer. Bloomberg values Foroughi at $11.6 billion (September 2026) versus roughly $4.2 billion for Jeff Green in recent estimates. The gap reflects AppLovin's much larger market value — even after both stocks crashed in 2026.
What is Jeff Green's net worth in 2026?
Jeff Green, the founder and CEO of The Trade Desk, is estimated at around $4.2 billion in recent reports, down from about $6 billion in Forbes' 2023 estimate. The decline follows a ~68% year-to-date collapse in The Trade Desk's stock in 2026, which cut the company's market cap to about $5.6 billion.
How are AppLovin and The Trade Desk different?
Both are independent advertising technology companies, but they sit on opposite sides of the market. AppLovin (Foroughi) is supply-side and mobile-first: its AXON engine helps app developers sell ad inventory, reaching 1.4 billion daily users. The Trade Desk (Green) is a demand-side platform (DSP): it helps advertisers buy programmatic ads across the open internet.
Did both CEOs lose money in 2026?
Yes — brutally. Foroughi lost about $13.5 billion as AppLovin fell 53.8% year-to-date, the third-worst S&P 500 stock. Green fared even worse in percentage terms: The Trade Desk dropped roughly 68% year-to-date on troubles with its Kokai AI platform and class-action lawsuits, shrinking his fortune by more than half.
Who gets paid more: Foroughi or Green?
Green's headline pay is bigger. He received an $834 million pay package in 2022 (mostly stock options), while Foroughi's peak pay year was 2023 at $83.4 million. But Foroughi's ~11% AppLovin ownership dwarfs Green's stake in dollar terms — pay packages are the small number for both founders.
Is Adam Foroughi married?
Yes. Forbes lists Foroughi's marital status as married, and he has children — family trusts are referenced in AppLovin's ownership disclosures. He is famously private and keeps his family life out of the public eye.
How old is Adam Foroughi in 2026?
Adam Foroughi was born in 1980 in Tehran, Iran, and is 46 years old in 2026. His family fled to the United States during the Iran-Iraq War; he grew up in Southern California and graduated from UC Berkeley in 2001.
Where does Adam Foroughi live?
Forbes lists his residence as Truckee, California, near Lake Tahoe. He keeps a deliberately low profile despite running AppLovin from its Palo Alto headquarters.
