On this December 16, 2025, Elon Musk makes history as the first human being to cross the unimaginable threshold of a $600 billion personal fortune. According to Forbes, his wealth now stands at approximately $677 billion, fueled by a new valuation of SpaceX at $800 billion. Bloomberg corroborates this meteoric rise, estimating his net worth at nearly $638 billion.

In the unforgiving world of the ultra-wealthy, fortunes shift in the blink of an eye. Larry Ellison, cofounder, chairman and chief technology officer of Oracle, demonstrated this truth with dazzling clarity this week: propelled by a meteoric surge in his company’s stock, he briefly ascended to the pinnacle of global wealth, though his reign on that throne was destined to be fleeting.
