Elon Musk became the world’s first trillionaire thanks to his stake in SpaceX after the company’s public debut on June 12. Prediction market traders think that Mark Zuckerberg has the best chance of being next, but it’s still a long shot.
Speculators on Kalshi give the Meta CEO a 32% chance of becoming the world’s second trillionaire. His net worth is estimated at just under $200 billion, according to Forbes, which Kalshi uses to determine whether to resolve the contract to “yes” or “no.” That means his net worth would have to quadruple to earn the title.
The contracts on Kalshi related to the question also expire by 2033, meaning if the person listed on the contract doesn’t become the second trillionaire by that point the contract will close. Kalshi’s event contracts related to the question also currently have low volume, with just over $7,500 traded.
Traders on the platform give Nvidia CEO Jensen Huang the next best odds, with 21% chance of obtaining a 13-digit net worth. His current net worth according to Forbes is a little north of $180 billion.
No one else is seen as having a more than 10% chance of becoming the second trillionaire. Michael Dell, CEO of Dell Technologies, has the third best chances, at 6%. That’s despite his current net worth, $240 billion, being greater than that of Zuckerberg or Huang’s.
Despite the low odds from prediction market traders, more than one trillionaire may be in the pipeline, if previous research is to be believed. An Oxfam report from January 2025 estimated that within a decade there would be five trillionaires.
Disclosure: CNBC and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.
