Elon Musk is no longer the world’s first trillionaire after a sharp decline in Tesla’s share price reduced his estimated net worth below the $1 trillion mark.
On June 12, 2026, Musk made financial history when SpaceX’s Nasdaq debut pushed his estimated fortune above $1 trillion for the first time. In the days that followed, some estimates placed his net worth as high as $1.5 trillion, making him the first person ever to reach the trillion-dollar milestone.
The record, however, lasted only a few weeks. Tesla experienced its largest single-day stock decline in more than a year, with shares dropping more than 14% after the company released its latest earnings report. Investors reacted to weaker-than-expected results and slower progress on Tesla’s artificial intelligence initiatives and planned robotaxi program, leading to a significant sell-off.
The decline in Tesla’s market value reduced Musk’s personal fortune by an estimated $18.6 billion in a single day. As a result, his net worth is now estimated to be between $725 billion and $730 billion, placing him below the trillion-dollar threshold he had briefly surpassed.
Despite the decline, Musk remains the wealthiest person in the world by a substantial margin, with an estimated fortune still well ahead of the second-richest individual. His wealth continues to be closely tied to the performance of companies including Tesla and SpaceX, meaning fluctuations in their market valuations can have a significant impact on his overall net worth.
The rapid rise above $1 trillion, followed by an equally swift drop below that level, highlights how quickly personal fortunes can change when they are largely based on publicly traded company valuations. In just six weeks, Musk went from becoming the first trillionaire in history to falling below the milestone, while still retaining his position as the world’s richest person.
