There are few clubs in the world as exclusive as The Forbes 400, and in 2025, the cost of entry has climbed higher than ever.
To secure a place among the wealthiest individuals now requires a minimum net worth of $3.8 billion, an increase of $500 million from last year, reflecting buoyant equity markets and a surge in asset values.
Despite the steep threshold, more than 90% of last year’s billionaires successfully retained their positions.
Still, over 10 new names managed to muscle their way into the elite club, reflecting both entrepreneurial agility and the market’s shifting opportunities. Their fortunes span industries as varied as coffee retail, cancer diagnostics, and the rapidly expanding artificial intelligence sector.
For the sake of this article, we will look at only 10 of these individuals. Cumulatively, these newcomers are valued at $96 billion. About three of them command individual fortunes above $10 billion, a sign that new wealth creation is accelerating at the very top of the pyramid.
The data also highlights how innovation-led industries, particularly AI, are increasingly shaping global wealth dynamics. For perspective, the combined wealth of these new entrants alone surpasses the GDP of several African economies.
- Net worth: $5.3 billion
- Source of wealth: Advertising technology
Andrew Karam, 43, is the cofounder of AppLovin, the software company that has become one of the most powerful players in digital advertising. Since its 2021 IPO, the stock has soared more than sevenfold, lifting the company’s market value far beyond its debut valuation of $25 billion.
Karam owned about 4% of AppLovin as of late 2024, before stepping below the SEC’s disclosure threshold and eventually leaving the company in December that year to focus on philanthropy and investing.
AppLovin began in 2012 as a mobile game developer before pivoting to advertising technology, a bet that has paid off spectacularly. In 2020, nearly three-quarters of its revenue came from gaming, but the business was sold in mid-2025 for more than $700 million. Meanwhile, the company’s AI-driven adtech platform has grown by almost 15,000% in four years, generating $3.2 billion in revenue in 2024 alone.
A graduate of Tufts University with degrees in economics and engineering, Karam previously cofounded Social Hour and Style Page, a social platform for designers.
Technology and Trade. The two T’s that make billionaires.
