Elon Musk ranks No. 1 among the world's billionaires, with Forbes putting him at $839B on its 40th annual World's Billionaires list in March 2026.
His fortune compares at more than double his 2025 figure and well ahead of every peer on both major wealth trackers. The World's Billionaires list is an annual estimate of billionaire net worth based on stock holdings, private-company valuations, and other assets. Musk's lead comes mainly from SpaceX and Tesla equity, so his ranking moves with those valuations rather than cash income.

How far ahead is Musk?
On the U.S. ranking, the gap is very large. USA Today reporting on the Forbes 400 put Musk at No. 1 with $908B in September 2026, over $530B ahead of No.
2 Jeff Bezos at $378B, in USA Today's Forbes 400 report. The global gap was also wide. Forbes reported Musk at $839B in March 2026, the highest total ever recorded then, in Forbes 2026 billionaires coverage. That March total was more than triple the next fortunes:.
- Larry Page, $257B, No. 2 globally
- Sergey Brin, $237B, No. 3 globally
- Jeff Bezos, $224B, No. 4 globally
Where does the fortune come from?
Musk owns about 42-43% of SpaceX and about 12-13% of Tesla. He also holds stakes in xAI and X holdings.
SpaceX and xAI together account for roughly 65% of his total in early 2026 estimates. That mix means SpaceX valuation changes now matter more for his rank than Tesla share-price moves alone.
Could the Tesla pay package widen the lead?
Tesla shareholders approved a roughly $1 trillion, 10-year Musk pay package on Nov. 6, 2025.
Support exceeded 75%. The award pays only if Tesla hits demanding milestones, including an $8.5T market capitalization. If those targets are met, the package would add a large new layer of Tesla-linked wealth on top of his current stake.
Why do the numbers change between trackers?
Each ranking is an estimate, not a bank balance. Private-company values, Tesla shares, and market timing can shift the total by tens or hundreds of billions. Bloomberg Billionaires Index listed Musk at No.
1 at about $929B on Oct. 1, 2026, confirming his lead across both major real-time trackers, in Bloomberg data cited by Global Startups Insights. One October 2026 comparison had Bloomberg at $914B while Forbes real-time showed about $981B. A SpaceX IPO or sharp Tesla move can add or erase hundreds of billions without changing his spending power.
