Elon Musk Net Worth: $862.4 Billion, and 82.5% Is Locked Up

Elon Musk is worth $862.4 billion as of 27 August 2026, and 82.5% of that sits in a company whose shares have existed for 74 days — shares he is contractually barred from selling until June 2027. That single sentence describes a change in the structure of the world’s largest fortune that almost no coverage has registered. Musk did not just get richer or poorer this year. The way his wealth is measured changed, permanently, on 12 June.

Until SpaceX listed, his biggest asset was a private mark — a number derived from occasional funding rounds and updated a few times a year. It is now a live tape that reprices every 15 seconds. And the arithmetic that follows from that is stark: every $1 move in SpaceX stock moves Musk’s net worth by $5.12 billion. Every $1 move in Tesla moves it by $0.70 billion. His most famous company is now roughly one-seventh as important to his wealth, per dollar, as the one he took public ten weeks ago.

What $397 billion of evaporation actually looks like

Hold his share counts constant and vary only price, and the destruction is measurable to the dollar.

Musk’s 4,766,475,230 economically-owned SpaceX shares were worth $961.9 billion at the stock’s peak close of $201.80 on 16 June. At $139.63 they are worth $665.5 billion. That is −$296.3 billion. His 699,580,882 Tesla shares — the full SEC beneficial-ownership figure — were worth $342.7 billion at Tesla’s $489.88 peak close in December and are worth $241.9 billion now, a fall of −$100.8 billion.

Together: $1.305 trillion at the two peaks, $907.5 billion today, −$397.1 billion or −30.4%.

The attribution is the part worth sitting with. Three-quarters of the loss — 74.6% — came from SpaceX, an asset that was not publicly traded ten weeks ago. Tesla, the company that dominates every headline about Musk’s wealth, accounts for barely a quarter.

On Forbes’ own methodology, peak net worth was roughly $1.204 trillion on 16 June, against $862.4 billion today — a decline of $341.4 billion, or 28.4%. We compute that figure ourselves rather than cite one, because the widely-circulated peak numbers ($1.0trn, $1.1trn, $1.32trn, $1.45trn) are mutually inconsistent and none is traceable to a primary source.

Why Forbes and the SEC disagree about Tesla — by $105 billion

There is a methodology gap here that materially understates Musk’s Tesla position, and it is worth understanding before you quote any net worth figure.

Forbes counts 395,620,252 Tesla shares. Musk’s Schedule 13G/A reports beneficial ownership of 699,580,882 shares, or 19.9%. The difference is exactly 303,960,630 — the entire 2018 CEO performance award, which Musk exercised on 16 June at $23.34 a share.

What happened to those shares is instructive. Of the exercised block, 17,531,857 shares were withheld at $404.66 to cover tax under a net-share settlement; the Form 4 footnote states plainly that “the transaction did not involve any open-market sales of securities.” The remaining 286,428,773 became restricted stock subject to a service condition that does not vest until 19 January 2028.

So Forbes excludes them, which is defensible — they are not freely disposable. But it means the headline $862.4 billion omits roughly $105.1 billion of Tesla economics that the SEC does count. Any comparison between trackers, or across time, has to hold that methodology constant or it is measuring nothing.

The lockup nobody read properly

SpaceX’s IPO prospectus released shares in calendar tranches: 7% on 20 August, more on 9 September, 24 September, 9 October and 24 October. We covered the first of those in our report on the 319 million-share unlock.

Musk is in none of it. His agreement with the underwriters runs 366 days, and the prospectus is explicit: “Shares held by Mr. Musk will not be subject to any early release provisions.” Not the price triggers, not the calendar tranches, nothing. His entire 6.42 billion-share position is frozen until 12 June 2027.

That produces an unusual condition for a person at the top of a wealth ranking: fully marked to market, and fully illiquid. He absorbs every downtick in real time and can monetise none of it for another ten months.

There is a second detail in that document that has been widely missed. A separate clause would have released an additional 455.8 million shares early if SPCX closed at least 30% above its $135.00 IPO price — that is, at $175.50 or higher — on five of the ten trading days ending at the first earnings date on 4 August. The actual closes were 115.26, 118.24, 115.07, 113.50, 116.41, 112.55, 112.20, 108.37, 114.53 and 125.33. Zero of ten. The trigger failed, which means the December tranche is now the larger 797.6 million shares rather than 328.4 million.

The margin question, answered properly

Tesla is down 30.7% from its high, and Musk has pledged Tesla stock against personal borrowing, so the forced-sale question comes up every time the stock falls. On the disclosed facts, it is not close.

Tesla’s 2025 proxy discloses 235,998,721 shares pledged as collateral — 57.1% of his trust-held stock, worth $81.6 billion today. That number sounds alarming until you read the policy that governs it, which caps CEO borrowing at “the lesser of $3.5 billion or twenty-five percent (25%) of the total value of the pledged stock.”

Twenty-five percent of today’s collateral is $20.4 billion, so the binding constraint is the $3.5 billion absolute cap — just 4.29% of current collateral value. The same proxy discloses that as of end-2024, actual borrowing against all director and officer pledges was “less than 1% of the total value of the pledged shares.”

By our calculation, Tesla would have to fall to roughly $59 — another 83% — before a fully drawn $3.5 billion loan even touched the 25% policy limit. A 30% drawdown is not a margin event. It is not within sight of one.

One caveat we will state plainly rather than bury: the 235,998,721 figure is dated 15 September 2025. Tesla has not filed a 2026 proxy, and the 10-K incorporates Part III by reference. No more current pledge disclosure exists anywhere.

Where xAI went

A large share of published Musk net worth estimates still carry xAI as a separate private holding. It is not one.

SpaceX acquired X.AI Holdings Corp outright on 2 February 2026. Musk’s own Form 4 footnote reads: “Received when the Issuer completed its acquisition of X.AI Holdings Corp. (‘xAI’), pursuant to which xAI became a wholly-owned subsidiary of the Issuer.” X Corp — the former Twitter — had already folded into xAI in March 2025, so the whole structure now sits inside SpaceX and is captured in the SPCX share price.

There is no aggregate valuation for that deal in any filing, because it was accounted for as a reorganisation under common control, which produces no purchase-price allocation. Any “$X billion for xAI” figure in circulation is a press estimate, not a disclosed number. The last auditable private mark was $75.46 per share, confirmed three ways: the Series E price, the employee cash-election price in the merger, and ARK Venture Fund’s Level-3 valuation.

SpaceX also closed a $60 billion all-stock acquisition of Cursor developer Anysphere on 14 August, issuing 389,289,254 Class A shares — which diluted Musk from about 47.6% to 46.2%, six days before the first unlock tranche.

What Musk himself said about listing

Because SpaceX’s IPO materials were filed with the SEC, the interviews around it are primary documents rather than press paraphrase. Asked by JPMorgan chief executive Jamie Dimon why he listed now, Musk said:

“I’ve been asked for many years about taking SpaceX public — probably almost 10 years that people have been suggesting to me that I should take SpaceX public. We’ve been cash flow positive since around 2014 or 2015 and have been self-funding. Our private equity rounds were not fundraising rounds; they were liquidity rounds for investors and employees… What’s different now is that we’re embarking on a significant capital growth phase.”

— Elon Musk, CEO, SpaceX, in a filed Free Writing Prospectus, 8 June 2026

Dimon, in the same filing, offered the assessment that “Elon is the Edison of our time,” noting SpaceX had “built more than 650 rockets” and had “nearly 10,000 Starlink satellites in orbit.”

The most revealing disclosure, though, is in Musk’s Form 3. His 1.3 billion restricted SpaceX shares vest against conditions including market-capitalisation milestones “ranging from $500 billion to $7.5 trillion” and “the Issuer’s establishment of a permanent human colony on Mars with at least one million inhabitants.” A second tranche of 302 million shares requires “non-Earth-based data centers capable of delivering 100 terawatts of compute per year.” Those are filed vesting conditions, not rhetoric — and they are excluded from every net worth figure in this article.

The gap to second place

Larry Page is the world’s second-richest person at $279.7 billion, followed by Jeff Bezos at $268.1 billion, Sergey Brin at $258.0 billion and Michael Dell at $240.2 billion, all per Forbes on 27 August.

Musk is 3.08 times the second-richest person alive. Put differently: after shedding close to $400 billion of paper wealth in ten weeks, his lead over second place is still more than double Page’s entire fortune. Over the ten days from 17 to 27 August that gap widened by $21.7 billion.

We are not going to claim a full-year trend on that. No dated 1 January 2026 baseline for either man was obtainable, and a year-to-date net worth figure is conceptually broken in 2026 anyway, because his largest asset switched from a private estimate to a live market price halfway through the year.

A note on what we could not verify

Bloomberg’s Billionaires Index returned a CAPTCHA wall on every endpoint we tried, by two separate methods. We have therefore not printed a Bloomberg figure, and readers should treat the Bloomberg numbers circulating in secondary coverage as second-hand. Musk’s ownership percentages of the Boring Company and Neuralink are not disclosed in any filing and cannot be verified; Forbes lumps all private holdings into a single $14.1 billion line. Neither the reported $20 billion Boring Company round (which had not closed) nor Neuralink’s $42 billion secondary mark appears in a filed document.

FAQ

What is Elon Musk’s net worth today?

$862.4 billion as of 27 August 2026, per Forbes’ Real-Time Billionaires index, up $6.8 billion or 0.80% on the day. That figure comprises $665.5 billion of SpaceX stock, $45.9 billion of SpaceX options, $136.8 billion of Tesla stock and $14.1 billion of private holdings. He is ranked first in the world.

How much of Elon Musk’s wealth is Tesla?

Only 15.9% on Forbes’ methodology. SpaceX now accounts for 82.5%. This is a reversal of the position that held for most of the last decade, and it happened when SpaceX listed on 12 June 2026 and its shares began repricing daily. On the SEC’s broader beneficial-ownership basis Tesla is worth more — $241.9 billion rather than $136.8 billion — because the SEC counts 286 million restricted shares that Forbes excludes.

Can Elon Musk sell his SpaceX shares?

No. His shares carry a 366-day lockup running to 12 June 2027, and the prospectus states that shares held by Musk “will not be subject to any early release provisions.” Other holders are released in calendar tranches beginning 20 August 2026, but Musk is excluded from all of them. His stake is fully marked to market and fully illiquid.

Is Elon Musk at risk of a margin call on his Tesla shares?

Not on the disclosed facts. He has pledged 235,998,721 Tesla shares, but Tesla’s policy caps CEO borrowing at the lesser of $3.5 billion or 25% of pledged value, and the company disclosed that actual borrowing against all officer pledges was under 1% of pledged value at end-2024. By our calculation Tesla would need to fall roughly another 83%, to about $59, before a fully drawn facility reached the policy limit. Note the pledge figure dates from September 2025; no more recent disclosure exists.

How much has Elon Musk lost in 2026?

Holding his share counts constant, his two public stakes fell from $1.305 trillion at their respective peaks to $907.5 billion at the 26 August close — a decline of $397.1 billion, or 30.4%. About 74.6% of that came from SpaceX and 25.4% from Tesla. On Forbes’ methodology, peak net worth of roughly $1.204 trillion on 16 June has fallen to $862.4 billion, down 28.4%.

Who is the second-richest person in the world?

Larry Page, at $279.7 billion per Forbes on 27 August 2026, ahead of Jeff Bezos at $268.1 billion. Musk is 3.08 times richer than Page. His lead over second place, at $582.7 billion, is more than twice the size of Page’s entire fortune.
