According to Kalshi prediction market traders, Mark Zuckerberg has a 32% chance of reaching a $1T net worth before 2033, making him the clear favorite to become the world's second trillionaire after Elon Musk. Nvidia's Jensen Huang is his closest contender with a 21% chance, while Michael Dell ranks third with a 6% probability. Zuckerberg's estimated net worth sits below $200B today, but investors believe Meta's AI investments could boost long-term growth. Huang's net worth is around $182B, ballooned by Nvidia's dominance in AI chips. The contracts utilize Forbes' billionaire estimates, with total trading volume standing just over $7,500. Elon Musk's rise to trillionaire status followed SpaceX's public debut on 12 June; his wealth has fallen by about $350 billion due to weaker SpaceX shares, but he remains the wealthiest person with a net worth of $946.7 billion. An Oxfam report published in January 2025 forecasts the world may produce up to five trillionaires over the next 10 years.
