Elon Musk became the world’s first trillionaire following SpaceX’s initial public offering on June 12. Prediction markets indicate that Mark Zuckerberg has the greatest likelihood of joining the trillionaire ranks, though the odds remain modest.
These Kalshi contracts expire in 2033, and will terminate if the designated person does not become a trillionaire by that date. At present, trading volume is modest, with just over $7,500 exchanged.
Nvidia CEO Jensen Huang is considered the second‑most likely candidate, with a 21% probability of reaching a $100 billion fortune. Forbes reports his current net worth slightly above $180 billion.
No other individual is assigned a greater than 10% probability of becoming the second trillionaire. Michael Dell, chief executive of Dell Technologies, ranks third with a 6% probability, despite his net worth of $240 billion exceeding that of Zuckerberg or Huang.
Despite the modest probabilities indicated by prediction markets, multiple trillionaires may emerge, as suggested by recent research. An Oxfam report released in January 2025 projected that five trillionaires could exist within a decade.
