Elon Musk's net worth fell below $900 billion on Monday, July 13, 2026, as SpaceX shares continued to decline [1].

The drop marks a significant shift in the valuation of Musk's primary assets. Because SpaceX is a cornerstone of his wealth, the volatility of its share price directly impacts his status as one of the world's wealthiest individuals.

SpaceX shares fell 4.45% to just under $140 [3]. This movement brings the stock price closer to its original IPO valuation. According to reports, the shares have dropped more than 30% from a recent peak [4].

Estimates of Musk's current fortune vary across financial trackers. Forbes said that his net worth fell below $900 billion [1]. However, other reports from MSN estimated his wealth at approximately $957 billion [4].

Despite the recent tumble, some market observers maintain a positive outlook on the company's future. "Analysts remain overwhelmingly bullish on the rocket maker," Forbes analysis said [1].

The decline in share value has stripped Musk of his trillionaire status. Yahoo Finance analysis said that SpaceX stock remains Musk's most valuable asset [2]. The downward trend follows a period of high valuation that previously pushed his net worth into record territory.

Market analysts are monitoring whether the stock will stabilize at the IPO price or continue to slide. The current volatility reflects a broader adjustment in how investors value the private aerospace company's growth potential relative to its initial public offering price.

The decline in Musk's net worth underscores the high concentration of his wealth in SpaceX and Tesla. When a single asset like SpaceX experiences a 30% drop from its peak, it creates massive swings in his personal balance sheet. This volatility demonstrates the risk associated with wealth tied to high-growth tech stocks, where market sentiment can erase billions in paper wealth regardless of the company's operational success.
