2025’s Youngest Billionaires Are Redefining America’s Wealth

The 2025 edition of the Forbes 400 list features a growing group of entrepreneurs and tech leaders who have achieved billionaire status before reaching age 50. While the average age on the list is 70—with 23 individuals in their 90s—the youngest billionaires are reshaping what it means to join the ranks of America’s wealthiest.

Thirty-three people under age 50 made the list this year, up from 26 in 2024. The ten youngest, all aged 42 or below, now hold a combined net worth of nearly $357 billion, up sharply from $273 billion a year ago. Much of that increase comes from Meta CEO Mark Zuckerberg, whose personal wealth grew by $72 billion in the past year.

At the top of the list among the youngest is Edwin Chen, a 37-year-old AI entrepreneur who debuts with an $18 billion fortune. He is joined by other notable names under 40, including Robinhood’s Vlad Tenev and AppLovin investor Eduardo Vivas.

Lukas Walton, heir to the Walmart fortune, is the only one among the ten who inherited his wealth rather than earning it through startups or investing.

Here’s a look at the ten youngest billionaires on the 2025 Forbes 400:

10. Nathan Blecharczyk

Nathan Blecharczyk, 42, co-founded Airbnb and currently oversees the company’s technical operations.

He was the first engineer at the company, which began with a single air mattress and has grown into a global business with over 2 billion guest stays in more than 220 countries. His estimated net worth is $8.7 billion.

9. Mark Zuckerberg

Meta CEO Mark Zuckerberg, 41, added billions to his wealth this year as shares of Meta rose 42%. His current net worth stands at $253 billion, making him the third-richest person in the United States.

Zuckerberg heavily pushed into artificial intelligence in 2025, acquiring 49% of Scale AI for $14 billion and hiring key talent from OpenAI to lead Meta’s new AI division.

8. Dustin Moskovitz

Dustin Moskovitz, 41, helped launch Facebook alongside Zuckerberg while they were students at Harvard. He later left the company and founded Asana, a workflow software firm that went public in 2020.

With a net worth of $12 billion, Moskovitz also runs the Good Ventures Foundation with his wife, Cari Tuna. Together, they have donated nearly $4 billion to causes such as biosecurity and effective altruism.

7. Brian Venturo

At 40, Brian Venturo joins the Forbes 400 for the first time. He is the co-founder and Chief Strategy Officer at CoreWeave, which started as a crypto-mining project but pivoted to become a fast-growing provider of AI-focused cloud infrastructure. The company went public in March and has since doubled its market valuation to nearly $50 billion. Venturo holds an estimated 7% stake, valuing his fortune at $4.2 billion.

6. Baiju Bhatt

Robinhood co-founder Baiju Bhatt, also 40, has a net worth of $6 billion. Bhatt, whose parents immigrated from India, helped with Robinhood’s rise during the pandemic-fueled trading surge.

He stepped down from executive duties in 2024 but remains on the board and owns a 6% stake. The company has seen a 400% increase in its stock price, fueled by growth in crypto-related revenue and a range of new offerings, including IRAs and high-yield savings accounts.

5. Josh Kushner

Venture capitalist Josh Kushner, 40, built his $5.2 billion fortune through Thrive Capital, the firm he founded and manages. While born into a prominent New York real estate family and married to model Karlie Kloss, Kushner has earned his place on the list by backing major tech companies like Stripe and OpenAI. Thrive Capital now manages more than $15.5 billion in assets.

4. Eduardo Vivas

Eduardo Vivas, 39, built his $3.8 billion net worth through ventures in advertising tech and gaming. A high school dropout who once packed bags in a warehouse, he later founded Bright.com, which was acquired by LinkedIn in 2014. Vivas also joined AppLovin as an early investor and board member in 2018. His nearly 2% stake in the company is now worth $3.5 billion.

3. Lukas Walton

Lukas Walton, 38, inherited a portion of the Walmart fortune after his father, John Walton, died in a 2005 plane crash. With a net worth of $39.8 billion, he is the only one among the ten youngest billionaires who inherited his wealth. Though he holds stakes in Walmart and Arvest Bank Group, Walton focuses on Builders Vision, an investment firm he founded to fund sustainability efforts. The platform has invested over $3 billion since its launch in 2021.

2. Vlad Tenev

Vlad Tenev, 38, co-founded Robinhood and currently serves as its CEO. The platform now has 26 million customer accounts and is expanding into credit cards, IRAs, and other financial products.

Tenev has a net worth of $5.8 billion and continues to position Robinhood as a major competitor to established firms, such as Charles Schwab.

1. Edwin Chen

Edwin Chen, 37, is the youngest person on this year’s Forbes 400. With a net worth of $18 billion, he founded Surge AI in 2020 to improve the quality of training data for artificial intelligence models.
