Mark Zuckerberg will achieve a net worth of $1 trillion by December 31, 2026.

Elon Musk's net worth, which initially surpassed $1.1 trillion following SpaceX's $75 billion IPO, has since fallen by $240 billion due to a drop off in the company's value. Despite this fluctuation, prediction markets continue to identify Mark Zuckerberg as the most likely next individual to reach the trillion-dollar milestone, albeit still considering it a long shot.
