On March 10, 2026, Forbes published its annual list of the world’s billionaires and put Elon Musk‘s net worth at $839 billion. Three months later, on June 12, Wikipedia’s summary of the Bloomberg Billionaires Index says he became the first person the index had ever valued above a trillion dollars, at $1.11 trillion. A month after that, on July 13, the same index showed him at $876 billion. Same person, same year, three very different numbers, and none of them is a mistake.
That is the first thing to understand about net worth. It is not a fact you look up. It is an estimate made on a particular date, by a particular publisher, using particular assumptions about assets that mostly cannot be sold at the listed price. This guide explains how the estimates are built, why they disagree, why founder and crypto wealth is especially hard to pin down, and how to judge any net-worth figure you come across, including ones on websites that give a precise number with no source.
How this guide was researched
We used news coverage of Forbes’s 2026 list (The Hill via AOL, the Spokesman-Review and others, which restate Forbes’s own methodology note), Forbes’s own statement as quoted by a regional magazine, and Wikipedia’s summaries of the Forbes and Bloomberg methodologies, which cite the publishers. We did not retrieve Forbes’s or Bloomberg’s own methodology pages directly, so details of their private-company valuation methods are limited to what these secondary sources report.
A note on the search results we found: many of the top pages explaining “how Forbes calculates net worth” were anonymous, undated blog posts that contradict one another and the publishers themselves, for example on dates, discounts and which assets count. We did not use them for facts. That experience is part of the lesson of this article.
What “net worth” actually means
Net worth is assets minus liabilities at a moment in time. It is not income, salary or cash in the bank. A founder who owns 10% of a company valued at $2 billion on paper has a large net worth and possibly very little spendable money.
It also needs three qualifiers every time it is quoted: who estimated it, on what date, and how. A figure without those three is not a measurement. It is a rumor with a dollar sign.
The two big trackers and how they differ
Forbes publishes two things: an annual World’s Billionaires List and a real-time ranking. The 2026 annual list was published March 10, 2026, its 40th edition, and recorded a record 3,428 billionaires with a combined net worth of $20.1 trillion, according to news coverage of the release. Forbes said it used stock prices and exchange rates from March 1, 2026, and pointed readers to its real-time ranking for daily updated figures.
According to Wikipedia’s summary of Forbes’s method, positions in publicly traded stock are priced to market on a date roughly a month before publication, privately held companies are priced using prevailing price-to-sales or price-to-earnings ratios, and known debt is subtracted. The same summary notes Forbes’s own caution that stock prices fluctuate quickly, so a person’s true wealth and ranking at the time of publication can differ from the compiled situation, and that Forbes receives three kinds of responses from subjects: some try to inflate their wealth, some cooperate but leave out details, and some refuse to answer.
Bloomberg publishes a daily index. According to Wikipedia’s summary, it updates on days when the U.S. stock market is open, covers 500 billionaires, tracks stock prices and publicly disclosed holdings, and values private companies using derived or reported information compared live with public competitors. It put the total value of its list at $11.9 trillion as of December 30, 2025.
| Feature | Forbes World’s Billionaires List | Bloomberg Billionaires Index |
|---|---|---|
| Cadence | Annual list (2026 edition: March 10) plus a separate real-time ranking | Daily, on U.S. market days |
| Pricing date for the annual list | Stock prices and exchange rates as of March 1, 2026 | Rolling, updated daily |
| People covered | 3,428 billionaires in 2026 | 500 |
| Public stock | Priced to market (annual list: about a month before publication) | Tracked with live prices |
| Private companies | Priced using prevailing sales or earnings multiples (per Wikipedia’s summary) | Valued by comparison with live public competitors (per Wikipedia’s summary) |
| Debt | Known debt subtracted | Not detailed in the sources we read |
Two more facts show how much the date and the method matter. Forbes valued Elon Musk at $839 billion as of March 1, up from $428 billion on its previous list. And the news coverage of that list also named Changpeng Zhao, listed under “cryptocurrency exchange,” at $110 billion, and Michael Saylor, listed at $3.9 billion with sources including MicroStrategy and bitcoin. For the last two, the figures depend heavily on how a private exchange stake and a large bitcoin-linked holding are priced on a given day.
Seven reasons the same person gets different numbers
1. The valuation date. Stock prices and exchange rates move daily. The Musk numbers above came from three different dates, and a price move over a few weeks can change a fortune by tens or hundreds of billions.
2. Private companies have no live price. Someone must assume one. Common approaches are the last funding round’s valuation, multiples of sales or earnings from comparable public companies, or analyst judgment. Different assumptions produce different answers, and the gap widens as the private company’s size grows.
3. Ownership stakes and dilution. A founder’s percentage shrinks with every funding round, option grant and share sale, and public records may lag behind the real cap table.
4. Share classes. Investors often hold preferred shares with rights that founders’ common shares lack, which can make the founder’s slice worth less than a simple percentage suggests. The worked example below shows how.
5. Debt and pledges. Loans against shares reduce true wealth, but they are not always visible.
6. Liquidity. A stake that cannot be sold quickly, or at all because of lock-ups or transfer restrictions, is worth less in practice than its paper value. Publishers differ on whether and how much to discount for this, and sources we saw disagree on the size of any discount, so do not quote one.
7. What counts as wealth. Real estate, art, trusts, family holdings, philanthropic pledges and currency conversions all involve judgment calls. Forbes notes that heirs’ fortunes are not combined with family members’ unless each qualifies separately.
None of these makes one publisher “right” and the other “wrong.” They make the number a range with a date on it, and responsible writers present it that way.
Founder wealth is mostly paper: a worked example
Here is a hypothetical founder, with invented numbers, to show how a headline can shrink. This is an illustration, not a real person or tax advice.
Setup. A founder owns 15% of the company’s fully diluted shares. The latest funding round valued the company at $800 million after the investment. Investors hold preferred shares equal to 40% of the company, with a combined $200 million invested under a standard “1x non-participating” preference, meaning each investor can either take back their money first or convert to common shares, whichever is worth more. Employees, angels and others hold the remaining 45% as common shares.
| Scenario | Calculation | Founder’s value |
|---|---|---|
| A. Headline from the funding round | 15% of $800 million | $120 million |
| B. Same, with a 20% discount because the shares cannot be sold | $120 million less 20% | $96 million |
| C. Company is sold for $300 million | Investors take their $200 million preference because converting would yield only 40% of $300 million, or $120 million. The remaining $100 million is split among common holders (60% of shares), and the founder holds 15 of those 60 points, or one quarter | $25 million |
| D. Scenario C after an illustrative 25% tax | $25 million less 25% | $18.75 million |
The same person is “worth” $120 million or $18.75 million depending on the question asked. A net-worth site that multiplies a funding-round valuation by an ownership percentage reports scenario A, and most readers assume it is cash. This is why serious publishers describe founder wealth as an estimate of paper value, and why scenario C is the more realistic picture of what the founder could receive if the company were sold for much less than its headline valuation.

Crypto and Web3 founders: why the numbers swing
Crypto wealth adds four extra layers of uncertainty. These are general explanations, not findings about any named person.
Circulating versus fully diluted value. A token’s headline valuation often multiplies the price by the total supply, but only part of that supply may be trading. A founder’s allocation can be worth far less if sold into a market that cannot absorb it.
Vesting and unlocks. Founder and investor tokens usually unlock on a schedule. Locked tokens cannot be sold yet, and the schedule may be public or private. A tracker that counts them at full market price is estimating, not reporting.
Liquidity and price impact. Selling a large position moves the price against the seller. A million-dollar position and a billion-dollar position are not valued the same way in practice.
Ownership of the platform itself. A founder of an exchange or protocol may own a private company, tokens or both, with limited public disclosure. Forbes’s March 2026 list gave Changpeng Zhao’s wealth as $110 billion and Michael Saylor’s as $3.9 billion, but a reader cannot reconstruct either figure without the publisher’s private assumptions.
The practical lesson: crypto net worths are among the most date-sensitive numbers in publishing. A figure from last month, or last week, may be stale.
The threshold problem: who nobody is counting
Forbes’s list is, by definition, a list of people estimated to be worth at least $1 billion. Bloomberg’s covers 500 billionaires. Neither mainstream tracker publishes figures for people below those thresholds. That means a site stating that a founder, executive or investor is worth “$40 million” or “$250 million” usually has no authoritative source. The number is typically a guess assembled from funding announcements, a title or someone else’s guess.
This is a significant problem for biography sites. Readers searching for an entrepreneur’s net worth expect an answer, and many pages supply one. A trustworthy alternative is to publish what can actually be verified: public-company holdings from regulatory filings, disclosed funding rounds, token allocations the project has published, and clear statements such as “no reliable public estimate exists.” That honesty is a quality signal, not a failure.
How to check a wealth claim yourself
You do not need to be a financial analyst. These are the primary sources behind most credible wealth reporting. This section is general knowledge about public-record sources rather than a finding from our research, and the exact forms differ by country.
If the person leads a public company:
• Proxy statements and annual reports list how many shares executives, directors and large holders own. In the United States this is the proxy statement (DEF 14A).
• Insider ownership filings (in the United States, Forms 3, 4 and 5) show holdings and trades by officers and directors, and large-holder reports (Schedules 13D and 13G) show stakes above 5%.
• The IPO prospectus shows who owned what before the listing, and the lock-up terms that restrict early sales.
• Multiply the share count by a dated closing price, then say so: “as of [date], at the [date] closing price.”
If the company is private:
• Funding announcements give round sizes and sometimes valuations. A valuation is a negotiated price for the newest shares, not an audited value of the whole company.
• Regulatory filings of fundraising, such as Form D in the United States, show amounts raised but not the cap table.
• Cap tables and internal valuations are private, so outside estimates of a founder’s ownership are inferences. Say “estimated” and show your assumption.
If the wealth is in crypto:
• Project documentation and token-allocation disclosures show planned founder and investor allocations and vesting schedules.
• On-chain data shows balances at public addresses, but linking an address to a named person is uncertain, and labels can be wrong.
• Price and liquidity matter: note whether a figure uses circulating or fully diluted supply.
For everything: court filings, regulatory actions and reputable investigative reporting sometimes disclose real figures, and they outrank anonymous estimates.
Red flags in net-worth pages
Use this checklist on any net-worth page, including your own.
- • No date. A figure with no “as of” date cannot be checked.
- • No named source. “Estimated” is not a source. Look for a named publisher, filing or disclosure.
- • False precision. A number to the dollar, such as $42,317,000, for a private person suggests a formula, not a measurement.
- • Income mixed with net worth. Salary, revenue and valuation are three different things.
- • Wide tables of strangers. If the same page template appears for hundreds of people with different names and plausible numbers, many are likely generated.
- • Circular sourcing. One site cites another, which cites a third that copies Wikipedia.
- • Claims about people below billionaire level attributed to Forbes or Bloomberg. Neither publishes them.
- • “Lifestyle” padding. Descriptions of cars, houses and habits with no sources.
- • Contradictions with the publisher. If a page says Forbes uses fiscal-year-end prices but Forbes says it used March 1 prices, the page is wrong.
How to cite net worth responsibly
A good citation answers four questions in one sentence: whose estimate, what number, what date, and where to check it.
Weak: “Founder X has a net worth of $2.3 billion.”
Strong: “Forbes estimated Founder X’s net worth at $2.3 billion on [date], according to its real-time billionaires ranking [link].”
More habits that help:
• Prefer ranges and rounded numbers when you must go beyond the publisher’s own figure, and explain the assumption.
• Use “estimated,” not “is worth,” and never present a net-worth number as the person’s bank balance.
• Compare publishers honestly. If Forbes and Bloomberg differ, report both with dates and explain that methods differ, rather than choosing the larger number.
• State the absence of data. For someone below the billionaire threshold, “no reliable public estimate exists” is a valid and useful sentence.
• Update or date-stamp. Net-worth pages for volatile assets such as crypto go stale in days. Show the date and revise when you can.
• Correct mistakes visibly. Follow your Corrections Policy.
• Remember the person. Net worth is sensitive information about a real individual. Do not publish guesses as facts, and avoid details that could create safety or privacy risks.
Our site’s Editorial & Fact-Checking Policy sets the standard that net-worth content should meet.
A methodology box for publishers
If you run a biography or news site, a short, consistent box under every net-worth figure does more for credibility than any extra paragraph. Here is a template you can copy and adapt. Fill in the brackets, and delete the sentences that do not apply.
How we handle net worth. We report a net-worth figure only when a named publisher has estimated it. Figure: [amount], [publisher], as of [date] ([link]). Net worth is an estimate of assets minus liabilities on a given date. It is not income, salary or cash on hand, and it can change daily with markets.
Estimates differ between publishers because they use different dates and valuation methods, especially for private companies and crypto. We do not publish our own estimates. If no reputable estimate exists, we say so.

Frequently asked questions
Which is more accurate, Forbes or Bloomberg?
Neither is “the” accurate figure, because both are estimates made on different dates with different methods. Bloomberg updates daily and Forbes publishes an annual list plus a real-time ranking. Compare the dates, and use the one whose method and date suit your purpose.
Why did Elon Musk’s net worth differ between Forbes and Bloomberg?
Forbes’s annual list used March 1, 2026 prices and put him at $839 billion. Wikipedia’s summary of the Bloomberg index reports $1.11 trillion on June 12 and $876 billion on July 13. The dates differ, the methods differ and the valuations of private holdings are assumptions, so the numbers are not directly comparable.
Is net worth the same as income or cash?
No. Net worth is assets minus liabilities at a point in time. Much of a founder’s wealth may be shares in a company that cannot be sold at the listed price.
Can someone be worth billions on paper and have little cash?
Yes. If most of the wealth is in company shares or tokens that are locked up, restricted or illiquid, the paper value can be large while spendable money is small.
How do websites calculate net worth for people who are not billionaires?
Usually they do not calculate it from reliable data. Forbes’s list starts at $1 billion and Bloomberg covers 500 billionaires, so figures below that level are typically guesses from funding news, titles or other websites.
Why does a person’s net worth change every day?
Public stock prices, crypto prices and exchange rates move, and trackers such as Bloomberg’s index update on market days. Annual lists freeze a single date, which Forbes’s 2026 list set at March 1.
Do trackers subtract taxes?
The sources we read say known debt is subtracted, but we did not find a statement about taxes in the methodology summaries, so check the publisher’s own methodology page.
How should I cite a net-worth figure?
Name the publisher, the number, the date and a link, for example: “Forbes estimated X’s net worth at $Y on [date].” Avoid presenting it as a fact about the person’s bank balance.
How often should a net-worth article be updated?
As often as the underlying data changes materially. For crypto-heavy wealth, that can mean weekly or faster. At minimum, show an “as of” date and revisit when a major funding round, IPO, token event or list update occurs.
Are the net-worth pages on search engines reliable?
Many are not. In our research, several highly ranked explanations of Forbes’s method were anonymous, undated posts that contradicted the publisher. Prefer pages that name their sources and dates.
A net-worth figure is a snapshot, an estimate and an opinion about assets that mostly cannot be sold at the stated price. Forbes and Bloomberg are the best public trackers we have, and they disagree because their dates, methods and judgments about private holdings differ. For founders and crypto leaders, the gap between headline wealth and realizable wealth is wider still, as the worked example showed. And for anyone below the billionaire threshold, there is usually no authoritative number at all.
The responsible response, for readers and publishers alike, is simple: ask who estimated it, on what date and how; prefer ranges and named sources to precise numbers; and say plainly when no reliable estimate exists. That standard also makes better content. Before you rely on any figure here, check the sources below and, where possible, open the publishers’ own methodology pages.
