Elon Musk is worth roughly $870 billion as of August 14, 2026, according to Forbes’ Real-Time Billionaires index — still the richest person on the planet, and not particularly close. Larry Page sits a distant second at about $283 billion, with Jeff Bezos third around $272 billion. Musk’s fortune is more than triple either one.
Almost none of that money is cash. It’s equity — mostly SpaceX and Tesla stock — which is why the number can swing by tens of billions of dollars in a single week. A fresh regulatory filing just gave the clearest picture yet of the biggest piece of that puzzle: Musk owned 48.4% of SpaceX as of June 30, 2026.

SpaceX Is Now Carrying the Fortune
SpaceX went public on June 12, 2026, raising about $85.7 billion in the biggest IPO on record and briefly pushing its market cap past $2 trillion. Before that listing, analysts had to guess at Musk’s stake using private funding rounds. Now there’s an actual stock price to point to.
That price puts his 48.4% stake at more than $900 billion, per Reuters’ estimate at the time of the filing. Worth noting: that’s the market value of his shares, not spendable cash. If SpaceX stock climbs, his paper wealth climbs with it. If it drops, billions vanish just as fast — without Musk selling a single share.
How Much Tesla Does He Own?
A July 2026 SEC filing put Musk’s beneficial Tesla ownership at 699.6 million shares — 19.9% of the class. Split two ways: 413.15 million shares sit in the Elon Musk Revocable Trust, while 286.43 million are restricted shares still tied to vesting conditions, meaning they’re not all equally liquid or “his” in the same sense.
Then there’s the pay package. Reuters reported in August 2026 that Musk’s latest Tesla compensation structure could ultimately be worth up to $1 trillion — but only if he hits demanding performance targets tied to Tesla’s valuation. Treat that figure as a ceiling, not money already banked.
SpaceX Absorbed xAI
Musk founded xAI in 2023, folding in Twitter/X (bought for $44 billion in 2022) not long after. In February 2026, SpaceX acquired xAI outright, making it a SpaceX subsidiary per Tesla’s annual filing. Tesla itself invested about $2 billion into SpaceX in March 2026, after converting a planned xAI investment into SpaceX shares once the merger closed. Musk’s space, AI, and social-media interests now sit under one roof.
Neuralink and The Boring Company
Both privately held, both much smaller pieces of the pie. Neuralink builds brain-computer interfaces; Musk is CEO. The Boring Company works on underground tunneling and transit infrastructure. Neither trades publicly, so their value only gets marked whenever a new funding round happens — making them the hardest parts of his fortune to pin down.
How He Actually Built the Fortune
Musk’s money didn’t start with Tesla. He co-founded Zip2 with his brother Kimbal in the 1990s; Compaq bought it in 1999. The proceeds fed into X.com, which became part of PayPal — and when eBay bought PayPal for about $1.5 billion in stock in 2002, Musk walked away with a major payout as its largest shareholder.
He didn’t sit on it. Same year, he founded SpaceX. Two years later, he became an early Tesla investor, then its CEO in 2008. Those two bets are what eventually turned a few hundred million dollars into hundreds of billions.
Timeline:
- 1999 — Zip2 sold to Compaq
- 2002 — PayPal sold to eBay for ~$1.5B
- 2012 — Musk enters the Forbes billionaire ranks
- 2021 — Becomes the world’s richest person during Tesla’s surge
- 2022 — Buys Twitter for $44B
- Feb 2026 — SpaceX acquires xAI
- June 2026 — SpaceX goes public
- Aug 2026 — Forbes pegs him at ~$870B
Yes, He Was Briefly a Trillionaire
When SpaceX went public on June 12, 2026, Forbes valued Musk above $1 trillion — the first person it had ever put in that bracket. It didn’t last. SpaceX shares slid, and by late July his estimated fortune had dropped below $700 billion. It recovered as the stock rebounded, landing back around $869.9 billion by mid-August.
A $300 billion swing in two months is the clearest proof that a headline net-worth number is a snapshot of asset prices, not a bank balance.
Net Worth ≠ Cash in Hand
Musk’s actual cash position isn’t public, and it’s a fraction of $870 billion. Turning a meaningful chunk of his equity into cash would mean selling shares, eating tax bills, and moving markets in the process. He’s historically borrowed against shares as collateral instead of selling them — standard practice for founders sitting on concentrated stock positions, but a reminder that “net worth” and “money he could spend today” are very different things.
Life Outside the Balance Sheet
Born in Pretoria, South Africa, on June 28, 1971, Musk studied in Canada at Queen’s University before transferring to Penn for degrees in physics and economics. He briefly enrolled at Stanford, then dropped out to chase internet startups — the decision that led to Zip2, PayPal, SpaceX, and Tesla.
He’s been married three times (to author Justine Wilson, and twice to actress Talulah Riley) and has children with several partners, including Wilson, musician Grimes, and Neuralink executive Shivon Zilis — a family that’s grown and shifted enough that any fixed count goes stale fast. On property: he said in 2020 he’d sell most of his physical assets and has offloaded several California homes since. Real estate is a rounding error next to his equity stakes.
Why the Number Moves So Much
Three things drive the volatility:
- SpaceX — Musk’s 48.4% stake means small percentage swings move tens of billions.
- Tesla — still a major shareholder, so Tesla’s stock price does the same thing on a smaller scale.
- Private valuations — Neuralink and The Boring Company are only priced when they raise money, so their contribution is more guesswork than the public holdings.
Different trackers also value restricted shares, options, and private stakes differently, which is why Forbes and Bloomberg rarely land on the exact same figure.
Is He Still No. 1?
Yes — as of August 14, 2026, Forbes has him at $869.9 billion, well clear of second place. But that position hinges almost entirely on two stocks. A sharp drop in either SpaceX or Tesla shares could close the gap fast.
FAQ
What is Elon Musk’s net worth in 2026? About $869.9 billion as of August 14, 2026, per Forbes — moving with his stock holdings.
How much of SpaceX does he own? 48.4%, per a filing covering the period through June 30, 2026.

How much Tesla stock does he hold? 699.6 million shares (19.9% of the class) as of a July 2026 SEC filing, including unvested restricted shares.
Did he really hit $1 trillion? Briefly — Forbes’ first-ever trillionaire valuation, on June 12, 2026, right after SpaceX’s IPO. It didn’t hold.
What companies does he run? SpaceX and Tesla are the core two. Neuralink and The Boring Company round it out; xAI is now a SpaceX subsidiary after the February 2026 merger.
Where does most of the money come from? His SpaceX and Tesla equity — not salary, not cash income.
Bottom Line
Elon Musk’s net worth sits at roughly $870 billion as of August 14, 2026. The figure itself is temporary — what matters is the structure behind it: a 48.4% stake in a newly public SpaceX, a substantial Tesla position, and smaller private bets in Neuralink and The Boring Company. SpaceX’s IPO made his fortune easier to track but no less volatile — one sharp move in either stock can shift his estimated wealth by tens of billions in a day. Any number you see attached to his name needs a date stamped on it. Today’s is about $869.9 billion, still No. 1 in the world.
