How Many Billionaires Are in America? Counting Them Three Ways
The Million Dollar Question: Right now, how many billionaires does the United States have?
A) About 902 B) About 989 C) About 1,265 D) All three – because it depends entirely on who’s counting, when, and by what rule
Read on for the answer.
Three different organizations tried to answer this question for roughly the same stretch of time, and came back with numbers that disagree by more than 275 people and close to $2 trillion. None of them made a mistake. They just weren’t answering the same question, even though every one of them used the word “billionaire” to describe it.
What it is
“How many billionaires are in America” sounds like something a government agency could answer the way it answers how many people live in Ohio. It can’t, because no government agency tracks it. The IRS doesn’t publish a billionaire headcount. The Census Bureau’s wealth surveys top out well short of identifying individual billionaires by name. There is no filing, license, or registry that comes with the status – “billionaire” is not a legal category anyone applies for or gets certified into.
Every number you have ever seen in a headline was built privately, by a media company or a data-intelligence firm, using public records, reporting, and informed estimation. That is not a knock on the number – some of this work is genuinely rigorous – but it means three different, equally serious attempts to count the same population can land in three different places, and none of them is “wrong” by the standards they set for themselves.
Who’s counting, and why
Forbes runs the business with the most name recognition, and it actually runs three separate counting products, not one. The World’s Billionaires List is published every spring – a snapshot of every billionaire Forbes’s reporters can identify worldwide, by country. The Forbes 400 is published every autumn and is capped, by definition, at exactly 400 people – the 400 richest Americans, not every American billionaire. And underneath both sits the Forbes Real-Time Billionaires tracker, a continuously updated internal ledger Forbes uses to maintain net-worth estimates year-round, which is where the other two products draw their numbers from at different moments.
Altrata (the wealth-intelligence firm formerly known as Wealth-X) runs a different kind of business: selling data on the ultra-wealthy to private banks, insurers, luxury brands, and nonprofits that need to find and understand this population, not publish a magazine ranking of it. Its annual Billionaire Census is built for that commercial audience, which rewards being as comprehensive as possible – a bank doesn’t want to be told about only the 400 biggest potential clients in the country.
Bloomberg is often assumed to be the third rival count, and it’s worth being direct about why it isn’t, really. The Bloomberg Billionaires Index is a real-time, continuously updated ranking – but of roughly the top 500 wealthiest people in the world, not a census of any one country. It exists to power market-moving financial journalism (“tech billionaires gained $845 billion this year”) rather than to answer “how many billionaires does the US have.” Bloomberg’s index was never built to produce that number, which is itself a useful data point about why the three-way comparison people expect to find doesn’t actually exist in a clean form.
Why the counts differ
Four things do almost all the work in separating a headcount of 902 from one of 1,265.
Scope. The Forbes 400 counts exactly 400 people by design – it has done so since 1982, when the cutoff was $75 million, not a billion dollars. It was never meant to be a billionaire census; it just happens that, for the last couple of decades, essentially everyone on it has been a billionaire anyway. The World’s Billionaires List and the Altrata Census both aim for comprehensive coverage instead, which is the main reason either one is larger than 400.
Timing. Wealth estimates are snapshots, and markets move between snapshots. Forbes’s own worldwide count rose from 902 U.S. billionaires in its April 2025 list to 989 in its March 2026 list – an 87-person jump in eleven months, driven by a strong stock market and a wave of new fortunes tied to AI and data-center infrastructure. A count taken in a rising market will differ from one taken six months earlier purely because the underlying wealth changed, with no disagreement about methodology at all.
Valuation of the illiquid. A majority of billionaire wealth sits in stakes in companies that aren’t publicly traded, real estate, art, and other assets with no daily market price. Forbes and Altrata both have to estimate these, and reasonable analysts applying reasonable discount rates to the same privately held stake can land tens or hundreds of millions of dollars apart – enough, at the margin, to decide whether someone clears ten figures at all.
Residency and citizenship rules. “American billionaire” can mean citizenship, primary residence, or where someone’s fortune is domiciled, and the major counters don’t all draw that line identically. Altrata’s North America figure (1,337) runs noticeably ahead of its U.S.-only figure (1,265), which is its own small illustration of how much a count moves once you adjust the boundary by even one category.
How the counting actually works
Forbes’s method is largely reporter-built: journalists and analysts work from SEC filings, court records, real estate transactions, and direct interviews, then publish a named, individually sourced net-worth estimate for every person on the list – a slower, more labor-intensive process, but one that produces a number you can trace back to a specific person and a specific set of assets.
Altrata’s method leans more on data science: statistical modeling across public records, corporate filings, and its own proprietary wealth database, built to scale to a global list without a named estimate for every single entrant getting the same hands-on reporter treatment Forbes gives its flagship list.
Neither approach is more “correct” than the other – they’re built for different jobs. Forbes is selling journalism and a brand built on the credibility of its named rankings; Altrata is selling a database product where comprehensiveness and consistency across thousands of names matter more than a deep dive on any single one.
One wrinkle worth naming honestly: Forbes’s own September 2026 Forbes 400 coverage reported “a record 590 U.S. billionaires” too poor to make the 400 – which, added to the 400 who did make it, implies roughly 990 total U.S. billionaires. That number isn’t fully independent of the 989 figure Forbes published six months earlier in its World’s Billionaires List; both almost certainly draw on the same continuously updated Real-Time Billionaires tracker. The fact that they land within a single person of each other isn’t a coincidence proving anything beyond this: when Forbes measures broadly, in either March or September, its own tracker converges on a number near 990. The real gap opens up only when you compare that figure to Altrata’s.
What the numbers actually are
Here is every figure, with its date, side by side:
- Forbes, April 2025 (net worths as of March 7, 2025): 902 U.S. billionaires, up from 813 the year before. Global total more than 3,000, worth a combined $16.1 trillion.
- Forbes, March 2026 (net worths as of March 1, 2026): a record 989 U.S. billionaires, worth a combined $8.4 trillion. Global total a record 3,428, worth $20.1 trillion.
- Forbes 400, September 2026 (locked September 4, 2026): exactly 400 people, worth a combined $8 trillion, with a record $4.4 billion entry threshold – up $600 million from a year earlier – and, per Forbes’s own reporting, “a record 590” additional U.S. billionaires who didn’t clear that bar.
- Altrata, August 2026 (measuring year-end 2025): 1,265 U.S. billionaires, worth a combined $6,688 billion. Altrata’s North America figure (which adds Canada and other countries on the continent) runs to 1,337, worth $6.8 trillion. Global count: 3,795, an all-time high, worth $15.1 trillion.
Altrata’s U.S. number runs about 28% ahead of Forbes’s broadest 2026 figure for roughly the same period – the single largest gap among any pair of counts here, and the one that best illustrates how far “comprehensive” can stretch once an organization’s commercial incentive is to find as many billionaires as defensibly possible, rather than to publish a ranked, individually reported list.
The trend since 1982, from this site’s own Forbes 400 longitudinal panel: the Forbes 400 entry cutoff was $75 million in 1982 – not remotely a billion dollars, because “billionaire” barely existed as a cultural category yet. It crossed $250 million by 1990, $600 million by 2000, and first touched $1 billion in 2006 – the year the Forbes 400, for the first time, became a list of 400 billionaires rather than merely very rich Americans. That didn’t hold permanently: the 2008 financial crisis knocked the cutoff back down to roughly $950 million in 2009, the one year since 2006 that the 400th-richest American fell just short of ten figures, before the threshold crossed back over $1 billion in 2010 and never looked back – $2 billion by 2017, $3.8 billion in 2025, and the current record $4.4 billion. Even adjusted for inflation, that 1982 cutoff of $75 million comes to roughly $250 million in today’s dollars – meaning the real, inflation-adjusted bar to make the list has risen more than 15-fold since the list began, on top of whatever additional nominal distance the 2026 $4.4 billion threshold has put between itself and that inflation-adjusted baseline. The total wealth held by the whole 400 has grown on a similar curve: $126 billion in 1982 (about $420 billion in 2025 dollars) to roughly $6.65 trillion in 2025 and $8 trillion this year.
By state, the 2026 Forbes 400 – analyzed by Business Insider – puts California at 85 entrants, New York at 54, Florida at 49, Texas at 43, and Illinois at 18; those five states alone hold 249 of the 400. That tracks closely with this site’s own panel data for 2025 (California 81, Florida and New York tied at 53, Texas 43), which is itself a reminder that the Forbes 400’s state tallies are one of the more stable numbers in this piece – unlike the national headcount, the geography of American wealth hasn’t been reshuffling nearly as fast as the dollar figures attached to it.
Why picking the wrong number backfires
Treating any one of these as the official count causes real, specific problems, because each was built to answer a different real question.
Wealth-tax and inequality debates often cite whichever count makes the argument land harder, without naming which one. A debate about taxing roughly 1,000 households reads very differently from one about taxing nearly 1,300 – a 40% difference in who’s affected, hiding inside the same word.
Business and wealth-management targeting genuinely needs Altrata’s broader, modeled approach, because the question being asked – “who should we be trying to serve as clients” – doesn’t care whether a given billionaire ever makes a public magazine ranking. A private bank that filtered its prospect list down to just the Forbes 400 would be ignoring well over half of its actual addressable market, by any of the broader counts here.
Journalism keeps swapping numbers mid-story without flagging the swap. A piece will open with the dramatic, record-setting Forbes 400 framing – “a record 590 billionaires too poor to make the list” – then cite a completely different, broader figure two paragraphs later while discussing the overall size of the billionaire class, leaving a reader with one number in their head and a different one underneath the rest of the article.
The Forbes 400’s own “too poor” framing is its own small trap. It’s a vivid, quotable number, but treating the Forbes 400’s headline count (400) as a billionaire census – rather than the deliberately capped top-of-the-ranking product it has been since 1982 – is exactly how someone ends up citing “only 400 billionaires in America” in casual conversation when the real figure, by any count here, is well over double that.
What people get wrong
That the Forbes 400 is a billionaire census. It has been fixed at 400 names since the very first list in 1982, back when the cutoff was $75 million and most of the 400 weren’t billionaires at all. It only started looking like “the billionaire list” once the entry bar happened to cross ten figures decades later – the cap on the name never changed.
That Bloomberg publishes a rival count. It doesn’t, in any form comparable to Forbes’s or Altrata’s. Its Billionaires Index tracks roughly the world’s top 500 wealthiest people in real time for financial-market journalism, not a per-country billionaire census – there is no “Bloomberg says the U.S. has X billionaires” headline to find, because that was never the product’s job.
That growth rates across these counts are comparable. Forbes’s U.S. count rising from 902 to 989 in eleven months and Altrata’s global count hitting an “all-time high” of 3,795 describe different-sized, differently defined populations. Treating their percentage changes as tracking the same underlying reality is a category error, even when both percentages are individually accurate.
That a bigger number means the bar got lower. The dollar threshold to count as a billionaire hasn’t moved in any of these counts – $1 billion has meant $1 billion since the word existed. What moves is how many people clear that fixed line, and how generously an organization goes looking for them.
That Taylor Swift, Beyoncé, LeBron James, and Oprah Winfrey not making the 2026 Forbes 400 means they aren’t billionaires. By Forbes’s own public estimates, all four are: Taylor Swift at roughly $2 billion, Oprah Winfrey at roughly $3.4 billion, LeBron James at roughly $1.4 billion, and Beyoncé at roughly $1 billion. None of them cleared the 2026 list’s record $4.4 billion entry threshold. They’re exactly the kind of real, counted billionaire who disappears from view the moment someone mistakes “didn’t make the Forbes 400” for “isn’t a billionaire.”
Bottom line
The answer to the Million Dollar Question is D – all three are correct, depending on definition and date. Forbes’s April 2025 figure of 902 and its March 2026 figure of 989 are both real counts from the same organization’s broadest annual product, taken eleven months apart in a rising market. Altrata’s 1,265 is a real count too, from a firm whose business model rewards comprehensiveness over individually reported detail, measuring the 2025 year-end. None of the three is inflated or careless – they’re honest answers to three slightly different questions that all happen to be phrased as “how many billionaires are in America.”
The habit worth taking from this: the next time a number like “record 590 billionaires too poor for the list” or “nearly 1,300 American billionaires” crosses a headline, ask two questions before repeating it – which organization, and as of when. Those two questions take about five seconds and resolve nearly every apparent contradiction in this entire subject.
