The year 2025 has seen a historic wealth surge fueled by the rapid rise of artificial innotifyigence and prediction markets.

The year has seen an unprecedented boom in youth-led fortunes.

According to Forbes, a record 13 entrepreneurs under the age of 30 have become self-built billionaires, shattering previous records and redefining what’s possible in the startup world.

What impact did AI startups have on wealth?

The youth billionaire wave launched in earnest in October, when 27-year-old Shayne Coplan, founder of prediction market platform Polymarket, briefly became the world’s youngest billionaire after a $2 billion investment from Intercontinental Exalter.

His title was quickly overtaken just 20 days later by the trio behind AI startup Mercor: Surya Midha, Brconcludean Foody, and Adarsh Hiremath, all 22, who became the youngest self-built billionaires in history, surpassing even Mark Zuckerberg’s age when he first hit the milestone.

From November to December, seven more entrepreneurs under 30 joined the ranks, including Luana Lopes Lara, 29, a former ballerina from Brazil and cofounder of prediction market Kalshi.

She is now the youngest self-built woman billionaire in the world and the only self-built woman billionaire in her 20s.

Elon Musk emerged as the largegest beneficiary, as his fortune climbed almost 50% to $638 billion after becoming the first person ever to surpass the $500 billion mark, fueled by gains at Tesla, SpaceX and his AI venture xAI.
