Quick answer: Elon Musk’s net worth in September 2026 is estimated in the high hundreds of billions of dollars and moves with Tesla and SpaceX. Forbes’ real-time profile showed about $910 billion on 29 September 2026; Bloomberg’s Billionaires Index has shown about $908 billion (as of 9 September 2026). Those are estimates, not a bank balance. Most of the fortune is equity in Tesla, Inc. and SpaceX, which went public in June 2026.
This figure is one entry in our Forbes celebrity net worth guide.
This guide explains how those estimates are built, where the shares sit, and how the number jumped above $1 trillion after the SpaceX listing and then fell back. For other large, equity-driven fortunes on this site, see Mark Zuckerberg’s net worth and MacKenzie Scott’s net worth.

What “Elon Musk net worth” actually measures
Trackers multiply estimated share counts by market prices, then add private-company marks and subtract known debt. They do not audit Musk’s taxes, spending, or margin loans in full. When Tesla’s stock moves a few percent, the headline net worth can move by tens of billions of dollars in a day.
Two reputable trackers rarely match. Forbes and Bloomberg use different Tesla share counts (including how they treat performance awards), different SpaceX marks, and different haircuts on private assets. Treat any single number as a snapshot.
Tesla: the public-market core
Musk joined Tesla’s board in 2004 and has been CEO since 2008. Public filings in 2026 have described his stake at about 11% of Tesla, excluding large blocks of restricted stock from later CEO awards that vest only if performance tests are met. In June 2026 he exercised options tied to the 2018 CEO performance award, which increased the number of shares he holds outright.
Tesla is the world’s most valuable carmaker on some market-cap snapshots in 2026. Because that equity is listed, it is the easiest piece of the fortune to mark to market — and the easiest to over-interpret. A high Tesla price does not mean Musk can sell that entire stake tomorrow without moving the stock.
SpaceX IPO and the trillionaire headline
SpaceX listed in June 2026. Reporting at the time put the company’s opening valuation near $1.8 trillion to $2 trillion, and Forbes wrote that Musk became the first person with a net worth above $1 trillion on 12 June 2026, driven largely by his SpaceX position (Forbes has cited about 38% including options).
After the IPO, estimates spiked — Wikipedia’s sourced timeline records an intraday peak near $1.45 trillion in the following week — then fell as SpaceX’s public shares sold off. By late July 2026, coverage described a drawdown of hundreds of billions of dollars from the peak. That is why a “trillionaire” label in June and an ~$870–900 billion estimate in September can both appear in the same year’s reporting.
xAI, X, Neuralink, and The Boring Company
xAI is Musk’s artificial-intelligence company. In 2025–2026, business press covered a tighter combination of xAI with X Corp. Private marks for xAI are not as transparent as Tesla. Neuralink (brain-computer interfaces) and The Boring Company (tunnels) are smaller in most published breakdowns than Tesla and SpaceX, but they still affect how complete a “net worth” story looks to readers searching related terms such as xAI valuation, Starlink, and X Corp.
Do not add those private marks to Tesla and SpaceX as if they were cash. They are illiquid, lightly disclosed, and revised when new funding rounds appear. For another founder fortune that is marked mainly after a public listing, see Ryan Smith’s net worth.
Income versus wealth
Musk’s Tesla pay has long been concentrated in stock awards, not a large cash salary. The 2018 performance grant and later award fights with Tesla shareholders are part of the public record. Annual “earnings” lists (for example creator or CEO cash estimates) are not the same as net worth. Net worth is a stock of assets; pay is a flow.
How the fortune grew (short timeline)
- 1999–2002: Zip2 sale and PayPal / X.com path created the first large cash stake.
- 2004–2008: Early Tesla investment and CEO role.
- 2012: First appearance on the Forbes billionaire list (about $2 billion in that era’s ranking).
- 2021: Tesla’s surge put him at the top of global rich lists at various points.
- 2024–early 2026: Trackers described crossings of $400B, $500B, $600B, $700B, and $800B as Tesla and SpaceX marks rose.
- June 2026: SpaceX IPO; first $1 trillion print on some lists.
- July–September 2026: SpaceX volatility; estimates back below $1 trillion on major lists.
