On Forbes Italia’s 2024 billionaire list, Elon Musk was estimated at $195 billion, Jeff Bezos at $194 billion, Larry Ellison at $141 billion and Jensen Huang at $77 billion. These are estimates from that list, not final year-end figures or a complete ranking limited to people with engineering credentials.
Here, “engineer” includes people with formal engineering credentials and people described by sources as having technical backgrounds. Net worth means an estimate of assets minus liabilities; it is not salary, annual income or cash available to spend. Because estimates move with share prices and private-company valuations, each figure below is tied to its source and date.
How to read a 2024 wealth ranking
There is no single, consistently measured 2024 leaderboard of billionaires who all meet one strict definition of “engineer.” Forbes Italia’s 2024 list ranks billionaires generally, while Interesting Engineering’s 2024 article identifies a broader group of billionaires with engineering or technical backgrounds. The figures from those publications should not be combined into one precise ranking: they use different snapshots and may apply different inclusion criteria.
The four Forbes Italia figures below are useful dated comparisons, but they do not establish the final value of each person’s fortune on December 31, 2024. Forbes Italia reported the following estimates on its 2024 list:

#1 Best Overall
| Person | 2024 estimate | Main wealth source | Role and ownership context |
|---|---|---|---|
| Elon Musk | $195 billion (Forbes Italia, 2024 list) | Tesla and SpaceX | Founder and executive; wealth trackers value public Tesla shares and estimate the value of private SpaceX interests. |
| Jeff Bezos | $194 billion (Forbes Italia, 2024 list) | Amazon | Amazon founder; his fortune is chiefly associated with his Amazon equity. |
| Larry Ellison | $141 billion (Forbes Italia, 2024 list) | Oracle | Oracle co-founder and major shareholder; Forbes reported roughly 40% ownership in September 2024. |
| Jensen Huang | $77 billion (Forbes Italia, 2024 list) | Nvidia | Nvidia co-founder and chief executive; his fortune is closely tied to Nvidia equity. |
These are list estimates, not amounts the individuals earned during 2024 or held as cash. For Musk, Ellison and Huang in particular, later 2024 estimates shifted as markets repriced their companies.
How these fortunes were made
Elon Musk: Tesla and SpaceX
Musk’s estimated fortune is associated mainly with his Tesla and SpaceX interests. Forbes’s asset breakdown dated November 22, 2024, estimated $195 billion in Tesla value in its accounting and discussed his SpaceX interest, options and valuation assumptions. That figure is an estimate of assets, not a cash balance or a record of what he had sold.
Tesla is publicly traded, so changes in its share price can quickly alter the estimated value of a large holding. SpaceX is private, making its valuation less directly observable in a public market; estimates depend on the valuation assumptions used by the tracker. The two components therefore do not have identical levels of market-price transparency.
Jeff Bezos: Amazon
Bezos’s wealth is chiefly tied to Amazon equity. His engineering education and his role in founding Amazon help explain the technical and entrepreneurial path behind the fortune, but the central wealth mechanism is ownership in the company he built. Blue Origin and his other interests are separate from Amazon’s central role in estimates of his wealth.

Larry Ellison: Oracle
Ellison’s fortune is chiefly associated with his substantial Oracle ownership. Forbes reported that he held roughly 40% of Oracle in September 2024. When Oracle’s share price rises or falls, the estimated value of that stake changes, affecting his reported net worth and ranking even if he has not sold shares.
Jensen Huang: Nvidia
Huang’s fortune is closely tied to Nvidia equity. In 2024, investor enthusiasm for Nvidia and demand associated with artificial intelligence coincided with a sharp rise in the company’s share price, lifting the estimated value of his stake. The link is between company valuation and estimated wealth, not a claim that the share-price increase was personal income.

A large ownership stake connects a person’s estimated fortune to the value assigned to the business. For publicly traded companies, wealth trackers can mark shares to the current market price; for private companies, they must use valuation estimates. If that value changes, the reported net worth can change even when the owner has not sold anything.
This paper gain is different from salary, dividends, realized proceeds from selling shares and available cash. A net-worth estimate does not show how much an individual could spend immediately, how much tax a sale might trigger, or what value could actually be realized by selling a large holding.
Best Value
Fortune’s November 29, 2024 report linked large estimated gains for Musk, Ellison and Huang to market growth and investor enthusiasm, including AI-related gains for Nvidia and Oracle. It reported estimated gains by that date of $119 billion for Musk, $83.2 billion for Ellison and about $80 billion for Huang. These are Fortune’s then-current estimates, not year-end totals or amounts of cash received.
What the comparison can—and cannot—tell you
- It shows ownership as the main wealth engine. For these figures, company equity and private-company stakes matter far more than engineering pay.
- It is a snapshot, not a permanent order. Public share prices and private-company valuation assumptions can change, so a person’s position depends on the list’s date and method.
- It is not an exhaustive engineer-only ranking. The cited sources do not offer one complete ranking using the same credential test and one end-of-year valuation method.
