On June 12, 2026, Elon Musk became the first person in history with a net worth exceeding $1 trillion – a number so large that most comparisons break down immediately. A trillion dollars. Not a company worth a trillion. Not a portfolio approaching a trillion. The man himself, on paper, worth more than the GDP of all but 19 countries on Earth. And then, less than two weeks later, it was gone.
Musk’s net worth dropped below $1 trillion less than two weeks after he became the first person to reach that milestone. The speed of the reversal was almost comic. He’d climbed a mountain that no human being had ever climbed, planted a flag, and slid back down before anyone had finished writing the commemorative articles. But the story of how he got there – and why it unraveled so fast – is more interesting than the number itself.
It involves the largest IPO in history, a stock that surged 67% in four days, an AI division that burned through billions while losing every one of its founding engineers, a $116 billion Tesla payday locked up until 2028, and a broader tech sell-off that reminded everyone, once again, that gravity still applies.
The IPO That Made History
SpaceX listed on Nasdaq on June 12, 2026, at $135 per share, raising $75 billion in the largest IPO in history. For a company that had spent more than two decades operating entirely outside public markets, the debut was seismic. For more than two decades, SpaceX built rockets, launched satellites, and rewired the economics of space travel entirely out of sight of everyday investors. That changed on June 12, 2026, when the company completed the largest IPO in history, opening ownership to the public for the first time.
SpaceX priced its IPO at $135 per share and began trading at $150 on June 12. The debut helped push Musk’s net worth above $1 trillion. Musk owned roughly 42% of the company at the time of listing, and his SpaceX stake, combined with his Tesla holdings and other assets, put his net worth at more than $1 trillion.
The first few days of trading were, by any measure, euphoric. The momentum continued on June 16 when SpaceX’s stock jumped to an all-time high, pushing Musk’s fortune to a record $1.45 trillion. After an initial surge that briefly pushed SpaceX past both Amazon and Microsoft in market capitalization, shares pulled back sharply. The $225.64 peak on June 16 would turn out to be the top. What followed was a swift and brutal correction.
The Drop
SpaceX hit an all-time high of $225.64 on June 16, 2026, then fell for two straight sessions, wiping out roughly 14% in 48 hours. By June 22, the stock had peaked at $225.64 intraday on June 16 before falling in three consecutive sessions. As of June 22, SPCX was trading near $165, down roughly 27% from its peak but still up approximately 22% from the $135 IPO price.
Several things happened at once, and they compounded each other. The stock fell 16.4% in one session partly because the first week of trading in SPCX options started June 17, allowing short sellers to finally bet against the stock and hedge in a practical way. Before options trading opened, bearish investors had almost no way to bet against the stock. Once that door opened, it moved fast. The slump for SpaceX came amid a broader sell-off in the tech sector. The tech-heavy Nasdaq Composite tumbled 1.4% in morning trading, erasing $680 billion in market value.
The drop came after shares of SpaceX and Tesla fell during a broader tech sell-off, as investors became more cautious about the long-term profitability of artificial intelligence. That AI skepticism matters enormously for SpaceX specifically, because the company’s bull case rests almost entirely on its xAI division delivering returns that, by most analysts’ math, would need to be roughly 100 times its current revenue to justify the stock price.
The xAI Problem
The most striking detail buried in SpaceX’s pre-IPO filings wasn’t the $75 billion raise or the historic valuation. It was this: xAI posted a $6.36 billion operating loss in 2025. All eleven of its co-founders had departed by the end of March 2026. Every single one of them. Gone before the company went public.
Before the IPO, Musk publicly said xAI was “not built right the first time.” The $60 billion Cursor acquisition was the response to that. Cursor is an AI coding tool with around 7 million developer users, and SpaceX paid $60 billion for it. Whether that bet pays off will define whether the current stock price makes any sense at all. xAI, which SpaceX absorbed via a 100% share merger in February 2026, lost $6.355 billion on the operating line in 2025 and spent $12.7 billion in capital expenditure, wiping out Starlink’s $4.423 billion operating profit and producing a consolidated net loss of $4.937 billion for the year.
The only division of SpaceX actually making money is Starlink. According to SpaceX’s S-1 filing, Starlink accounted for approximately 61% of total company revenue in 2025, generating $11.4 billion, up roughly 50% from $7.6 billion in 2024. As of March 31, 2026, Starlink had surpassed 10.3 million active customers across 160 countries and markets, more than doubling from 4.6 million subscribers at the end of 2024. That’s a genuinely strong business. But it’s being asked to carry an AI division that, at current trajectory, resembles a controlled burn more than a growth engine.
Morningstar analysts warned before the IPO that SpaceX was “significantly overvalued,” with their discounted cash flow model placing the company’s value at $780 billion – roughly 48% below the private market valuation of $1.5 trillion heading into the listing. Morningstar viewed xAI’s economics as posing “a material threat of value destruction” to the company. NYU finance professor Aswath Damodaran, widely regarded as one of the most rigorous valuation experts in the field, valued SpaceX’s equity at between $1.25 trillion and $1.35 trillion after reading the S-1 – still below the IPO price – and said the stock was “too richly priced.”
The Tesla Pay Package Twist
Separately from the SpaceX drama, another chapter of the Musk wealth story was unfolding at Tesla. On June 16, the same day SpaceX hit its all-time high, Musk exercised the entirety of his 2018 Tesla CEO pay package. He acquired 303,960,630 shares for a paper gain of about $116 billion, according to a new SEC filing. That package had been voided by a Delaware court in 2024, reinstated by the Delaware Supreme Court in late 2025, and finally delivered in full in June 2026 – the conclusion of a years-long legal fight over what was the largest executive compensation deal in corporate history.
The catch, and it’s a significant one, is that Musk can’t spend any of it for years. Those shares are restricted and do not vest until January 19, 2028, subject to a service-based condition. He cannot sell them today. After vesting, a further five-year lockup period begins, meaning Musk cannot sell the shares until 2033.
That restriction matters because it’s part of why Musk’s paper wealth can swing so dramatically without translating into anything he can actually use. His net worth subsequently declined by 31% following a slump in SpaceX’s stock price and new restrictions on $116 billion worth of Tesla shares. Forbes counted those restricted Tesla shares as a liability, not an asset, once the service condition was attached, reducing their contribution to his calculated net worth. Combined with the SpaceX slide, the result was a fall back below $1 trillion in under a fortnight.
What the Numbers Actually Mean
The Bloomberg Billionaires Index put Musk’s net worth at $946 billion as of late June – down from about $1.11 trillion less than 14 days earlier. The speed of that move is a reminder of how artificial the “trillionaire” label was in the first place. Musk doesn’t hold $1 trillion in cash. He holds equity stakes in companies whose valuations are updated in real time by markets that can swing 15% in a single afternoon.
Despite the decline, Musk’s fortune still far exceeds that of the second-richest person. The nearest rival on the wealth rankings is Google co-founder Larry Page, whose $296 billion fortune trails Musk’s by roughly $650 billion – a margin that amounts to more than twice Jeff Bezos’s entire net worth. The drop from $1 trillion back to $946 billion is a loss most people cannot conceptualize. And yet it still leaves Musk more than three times as wealthy as the next person on the list.
There’s a structural risk most coverage has glossed over: one significant concern is the December 2026 lock-up expiry. Right now, only about 4% of SpaceX shares are available to trade. The remaining 96% is locked up until December. When that supply hits the market, the thin-trading conditions that drove shares from $135 to $225 in days could easily work in reverse. Documents filed with regulators before the IPO disclosed that SpaceX ran a $4.9 billion deficit in 2025; its AI division alone burned through $12.7 billion in capital spending. How the stock holds up once early investors and employees are free to offload shares will serve as a significant gauge of market confidence.
The Weight of Being First
The historical comparisons were inevitable. Rockefeller became the first US dollar billionaire in 1916; when Musk’s wealth was $970 billion in early June 2026, it represented approximately 3% of US GDP – a larger share of the national economy than Rockefeller’s fortune ever commanded.
Politicians were quick to use the milestone as a prompt. American political figures including Elizabeth Warren and Zohran Mamdani used the milestone to call for the implementation of a wealth tax. Oxfam’s analysis found that at $1 trillion, Musk’s wealth would exceed the combined net wealth of the bottom 46% of humanity – roughly 3.8 billion people.
The IPO also created wealth far beyond Musk. Going public created fortunes not just for Musk, but for many employees. It is estimated that the IPO made millionaires, at least on paper, of more than 4,000 SpaceX employees – not just high-level executives, but employees in roles from cafeteria workers to contract staff. Private banks, wire houses, trust companies, and registered investment advisors sent teams to California, Texas, and Florida to court new SpaceX clients.

The Number That Keeps Moving
Losing trillionaire status after 13 days sounds dramatic. In another sense, it’s just the stock market doing what it always does. Musk still has a net worth approaching $1 trillion. He still owns roughly 42% of the company that just completed the largest IPO in history. He still holds more than a billion Tesla shares, the majority of which he can’t touch until at least 2028, and the 2018 package won’t fully unlock until 2033. The title came and went faster than a news cycle, but the underlying position hasn’t fundamentally changed.
What the “lost trillionaire status” framing reveals is how much of Musk’s net worth is built on projections about what xAI might become, what Starship might eventually charge per launch, and whether a $60 billion AI coding tool acquisition turns out to be prescient or catastrophic. The uncertainty cuts in every direction, including upward.
The December lock-up expiry will be the real test. When 96% of SpaceX’s shares are finally free to trade, the market will get its first genuine read on what long-term holders actually think the company is worth. Until then, the number on any given day – whether it reads $946 billion or $1.2 trillion – is less a fact than a forecast. The trillionaire crown was always going to sit uneasily on a head whose net worth moves faster than the news cycle can refresh.
