Elon Musk is no longer a trillionaire on paper. SpaceX shares closed Monday, July 20, at $119.85, down 3.3% for a seventh consecutive losing session and well below the $135 price set for the company’s June initial public offering.
Forbes’ real-time tracker estimated Musk’s fortune at about $785.2 billion on July 20. That still makes him the world’s richest person by a wide margin, but it leaves him roughly $215 billion short of the trillion-dollar mark he crossed when SpaceX began trading on June 12.
The reversal has been fast. SpaceX reached $225.64 on June 16, briefly lifting Musk’s estimated wealth to about $1.45 trillion. Monday’s close was nearly 47% below that peak and put SpaceX’s market value near $1.59 trillion, according to market data and The Wall Street Journal.
The numbers behind the fall
Musk’s fortune moves heavily with SpaceX because he owns roughly 4.8 billion shares and has options for 350 million more shares at an exercise price of about $8.40, according to Forbes and a June 17 SEC filing. At Monday’s close, the common shares alone had a gross market value of roughly $575 billion. The options had about $39 billion of intrinsic value before taxes and other adjustments.
That arithmetic is only a sensitivity check, not a personal balance sheet. Wealth trackers apply their own discounts and assumptions to restricted shares, options, private assets, debt and taxes. Musk also owns a large Tesla stake, so Tesla’s closing price matters alongside every move in SpaceX.
What “on paper” really means
The label matters because Musk does not have $785 billion sitting in cash. Most of the estimate is tied to securities whose quoted value can change by tens of billions in a single session. Selling a huge block could push the price down, trigger taxes and reduce his control of the companies.
The same mechanics explain how he became a trillionaire so quickly. SpaceX’s IPO made fewer than 5% of its shares available for public trading, according to Reuters. Heavy demand for a small float pushed up the market price used to value billions of Musk-held shares that he did not sell.
Could Musk become a trillionaire again?
Yes, and the threshold is closer than the headline number may suggest. A simple calculation using about 5.15 billion SpaceX shares and options implies that every $1 change in SpaceX could move Musk’s gross holdings by roughly $5.15 billion before tracker discounts. Filling a $215 billion gap would therefore take about a $42 rise in SpaceX—to roughly $162 a share—if Tesla and everything else stayed unchanged.
That is not a forecast. SpaceX’s first public earnings report and the release of more insider shares after the lockup period could both change the calculation. Axios reported that as many as 1.37 billion shares may become eligible for sale after the company reports second-quarter results.
Bottom line: Musk remains extraordinarily wealthy, but by the leading live estimate he is not a trillionaire now. His brief trillion-dollar crown was a market-price milestone, and another sharp SpaceX or Tesla rally could put it back within reach.
