Breakdown of the average billionaire's wealth worldwide 2026, by assets and age

Breakdown of the average billionaire's wealth around the world in 2026, by asset allocation and age

Public holdings make up the largest share of the average billionaires wealth, but the mix changes sharply with age. Billionaires under 50 hold about 63 percent of their wealth in public, listed shares, against about 40 percent for those aged 50 and over.

The way the average billionaire holds wealth is one of the least understood aspects of great fortune, and it turns out to depend heavily on age, shifting from concentrated equity among the young to a diversified mix among the old.

On the Altrata and Wealth-X figures, billionaires under 50 hold about 63 percent of their wealth in public shares, 20 percent in private holdings, 13 percent in liquid assets and 4 percent in real estate and luxury, a far more concentrated mix than older billionaires.

It is one of the clearest illustrations of how great wealth is really held, cutting through the popular image of yachts and mansions to show a billionaire class whose fortunes are, above all, ownership of businesses.

It is a breakdown that reveals as much about the sources of great wealth as about how it is invested, since the industries that mint young billionaires are precisely those whose fortunes are held in listed shares.

Few charts capture the changing shape of a fortune over a lifetime as clearly as this one, tracing the path from the concentrated equity of a young founder to the broad, diversified holdings of an established billionaire.

The rest is split between private business holdings, liquid assets such as cash and dividends, and a small share in real estate and luxury. The wider wealth picture sits in our billionaire wealth by industry, wealth by gender and wealth by region coverage.

Public shares fall with age: billionaires under 50 hold about 63 percent of their wealth in public shares, falling to about 40 percent by age 50, as private and liquid holdings rise.

The heavy weighting toward public shares among younger billionaires reflects the rise of technology founders, whose fortunes are tied to the listed equity of their companies, a link our Nasdaq stock market coverage frames.

A note on the data. The figures show the breakdown of the average billionaires wealth in 2026 by asset allocation and age, from the Altrata and Wealth-X Billionaire Census. Assets are public holdings, private holdings, liquid assets, and real estate and luxury, and shares are approximate.

The Billionaire Census draws on Altratas database of the global billionaire population, assessing all asset holdings including publicly and privately held businesses and investable assets, making it one of the most detailed sources on billionaire wealth.

The categories are public holdings, meaning listed company shares, private holdings, meaning stakes in unlisted businesses, liquid assets, meaning cash and dividends, and real estate and luxury assets such as property, art and yachts.

Billionaire Asset Allocation by Age

The table sets out the average billionaires asset allocation by age group in 2026. It shows public holdings falling and private and liquid assets rising as billionaires age, with real estate and luxury a small share throughout.

Reading across the age groups shows public holdings falling from 63 percent to about 40 percent, private holdings rising from 20 to about 32 percent, and liquid assets rising from 13 to about 24 percent.

Because the shares are averages across a large and varied population, individual billionaires can differ widely, but the broad pattern of a shift from public shares to a diversified mix with age is consistent.

How Is the Average Billionaires Wealth Split?

Across all billionaires, public holdings are the largest asset class at about 42 percent of wealth, followed by private holdings on about 31 percent, liquid assets on about 22 percent and real estate and luxury on about 5 percent.

Taken across the whole billionaire population, the allocation is weighted overwhelmingly toward business ownership, a defining feature that sets billionaire wealth apart from the wealth of ordinary households.

Across all billionaires, public holdings make up about 42 percent of wealth, private holdings about 31 percent, liquid assets about 22 percent and real estate and luxury about 5 percent, so business ownership makes up nearly three quarters of the total.

The weighting of billionaire wealth toward business ownership, public and private, is the single most important fact about how the very wealthy hold their fortunes, and it sets them apart from everyone else.

The overwhelming weight of business ownership in billionaire wealth, public and private together, is the defining feature that separates the balance sheet of a billionaire from that of an ordinary household.

The concentration of billionaire wealth in business ownership rather than property or cash is perhaps the single most important thing to understand about how the very wealthiest hold their money.

It is a distinction that shapes everything from how billionaires are taxed to how their wealth is passed on, and it begins with the simple fact that most of it is ownership of companies.

The overall allocation is heavily weighted toward business ownership, public and private, which together make up nearly three quarters of billionaire wealth, a concentration our billionaires around the world coverage frames.

Business ownership dominates: public holdings are about 42 percent of billionaire wealth and private holdings 31 percent, so business ownership makes up nearly three quarters of the total.

The dominance of business holdings over cash and property is the defining feature of billionaire wealth, distinguishing it from the wealth of ordinary households, which is held far more in property and pensions than in company shares.

Why Do the Young Hold So Much in Shares?

Public holdings, meaning listed company shares, are the largest single asset class for the average billionaire, but they dominate among the young. Billionaires under 50 hold about 63 percent of their wealth in public shares, far more than older billionaires.

The dominance of public, listed shares in young billionaire wealth is the single most distinctive feature of the age breakdown, and it separates the technology-driven young from every older cohort.

Billionaires under 50 hold about 63 percent of their wealth in public shares against about 40 percent for those aged 50 and over, one of the sharpest differences by age in the whole of billionaire wealth.

The scale of the difference in public holdings between young and old billionaires, more than twenty percentage points, is one of the most striking single findings in the asset-allocation data. The dominance of public shares in young billionaire wealth, and its steady decline with age, is the single clearest thread running through the whole of the asset-allocation data.

Because so much of the wealth of the young is a single listed shareholding, it is also the most transparent, visible daily in the share price, unlike the private and cash holdings that dominate older fortunes.

The concentration of young billionaire wealth in public shares reflects the rise of technology founders, whose wealth is largely the listed equity of the companies they built, a pattern our biggest companies by value coverage frames.

Highest among the young: public holdings make up about 63 percent of wealth for billionaires under 50, falling to about 40 percent for those aged 50 and over.

For billionaires aged 50 and over, public holdings fall to about 40 percent of wealth, as fortunes are gradually diversified into private holdings and liquid assets, a shift that comes with age and the sale of founding stakes.

The fall in public holdings with age, from about 63 percent among the young to about 40 percent among the old, is mirrored by a rise in private and liquid holdings, tracing the diversification of wealth over a lifetime.

How Do Private Holdings Change With Age?

Private holdings, meaning stakes in unlisted businesses, are a larger share of wealth for older billionaires. They make up about 20 percent of wealth for those under 50 but rise to about a third for billionaires aged 50 and over.

The larger place of private business holdings in older billionaire wealth reflects both the maturing of their companies and the deliberate diversification that tends to come with age and the transfer of wealth.

Private holdings rise from about 20 percent of wealth for billionaires under 50 to about 33 percent for those aged 50 to 70 and about 31 percent for those aged 70 and over.

The rise of private holdings with age reflects the natural broadening of a fortune, as a founder who began with a single listed company gradually acquires stakes in other, unlisted ventures.

The growing weight of private business holdings with age is a reminder that much of the worlds great wealth sits in companies that never appear on any stock exchange, held quietly within families.

The larger private share among older billionaires reflects the maturing of their businesses and the broadening of their holdings beyond a single listed company, a diversification our global stock markets by country coverage frames.

Rises with age: private business holdings rise from about 20 percent of wealth for the under 50s to about a third for older billionaires.

Private holdings are especially important for billionaires outside technology, in industries such as manufacturing, real estate and consumer goods, where much wealth is held in family-owned, unlisted businesses rather than listed shares.

The importance of private holdings outside technology reflects the many industries, from manufacturing to consumer goods, where great wealth is held in family-owned businesses that have never been listed on a stock exchange.

Why Do Older Billionaires Hold More Cash?

Liquid assets, meaning cash, income and dividends, rise steadily with age. They make up about 13 percent of wealth for billionaires under 50 but about 24 percent for those aged 70 and over, as older billionaires hold more of their wealth in cash.

The steady rise in liquid holdings with age is one of the clearest patterns in the data, reflecting a natural shift toward cash and safety as billionaires grow older and plan for succession.

Liquid assets rise from about 13 percent of wealth for billionaires under 50 to about 22 percent for those aged 50 to 70 and about 24 percent for those aged 70 and over.

The steady climb in cash holdings with age is one of the most consistent patterns in the data, and it speaks to the changing priorities of billionaires as they move toward succession and philanthropy.

The larger cash cushion of older billionaires is one of the clearest signs of how priorities shift with age, from building a fortune to preserving it and preparing to pass it on.

The rising liquid share with age reflects a natural shift toward safety and diversification, as older billionaires cash out founding stakes and hold more in liquid form, a shift our gold and other stores of value coverage frames.

Cash rises with age: liquid assets rise from about 13 percent of wealth for billionaires under 50 to about 24 percent for those aged 70 and over.

The larger cash holdings of older billionaires give them flexibility for philanthropy, succession planning and diversification, priorities that tend to grow in importance with age and the transfer of wealth to the next generation.

The larger cash holdings of older billionaires are not idle wealth but a deliberate provision for philanthropy, succession and diversification, priorities that grow in importance as billionaires age.

What Do Young Billionaires Hold?

Younger billionaires look very different from older ones. Those under 50 hold about 63 percent of their wealth in public shares and only about 20 percent in private holdings, the most concentrated allocation of any age group.

The distinctive profile of billionaires under 50, dominated by public shares, is a direct reflection of the technology boom that has minted so many young fortunes in listed equity.

The profile of the young billionaire, holding most of their wealth in the listed shares of a single company they founded, has become one of the defining images of the technology era of wealth creation.

The profile of the young billionaire, holding most of their wealth in the shares of a single company, is the direct product of the technology boom and the speed with which it has created new fortunes.

Their fortunes, tied to the daily movement of a single share price, are both the most visible and the most volatile of any age group, capable of swinging by billions in the space of a single trading session.

The distinctive allocation of young billionaires reflects the technology sector, which has the youngest and most self-made billionaires, whose wealth is overwhelmingly the listed equity of the firms they founded and still control.

Concentrated in equity: billionaires under 50 hold about 63 percent of their wealth in public shares, the most concentrated allocation of any age group, driven by technology founders.

This concentration also makes young billionaire wealth more volatile, since it rises and falls with the share price of a single company, unlike the more diversified holdings of older billionaires spread across private stakes and cash, a spread our billionaire share by region coverage sets in a wider context.

The concentration of young billionaire wealth in a single listed company makes it far more volatile than the diversified holdings of older billionaires, rising and falling sharply with the share price.

What Do Older Billionaires Hold?

Older billionaires hold a more balanced mix. Those aged 70 and over hold about 40 percent in public shares, about 31 percent in private holdings and about 24 percent in liquid assets, a far more diversified allocation than the young.

The balanced allocation of older billionaires, spread across public shares, private stakes and cash, is the product of decades of diversification and the practical demands of passing on great wealth. The contrast between the concentrated young founder and the diversified older billionaire captures, in a single comparison, how great wealth tends to evolve over the course of a lifetime.

The diversified holdings of older billionaires are the accumulated result of decades of investment decisions, gradually spreading a fortune that often began as a single concentrated stake.

The balanced allocation of older billionaires reflects decades of diversification, as founding stakes are sold and wealth is spread across private businesses, cash and investments, a shift our US financial markets coverage frames.

A diversified mix: billionaires aged 70 and over hold about 40 percent in public shares, 31 percent in private holdings and 24 percent in liquid assets, a far more balanced mix.

The larger liquid and private holdings of older billionaires reflect both prudence and the practicalities of succession, as wealth is prepared for transfer to heirs and foundations, a process that favors diversified, liquid holdings over concentrated equity.

The diversified, liquid-heavy allocation of older billionaires reflects the practical work of preparing great wealth for transfer to heirs and foundations, which favors flexible holdings over concentrated equity.

How Sharp Is the Age Contrast?

The contrast between the youngest and oldest billionaires is the sharpest in the data.

Those under 50 hold about 63 percent of their wealth in public shares and just 20 percent in private holdings, while those aged 70 and over hold a far more even spread across the four asset classes, a divergence our billionaire population by region coverage complements through geography.

A sharp contrast: billionaires under 50 hold far more in public shares and far less in private and liquid assets than those aged 70 and over.

Equity out, diversification in: as billionaires age from under 50 to 70 and over, public holdings fall sharply while private and liquid assets rise.

How Does Allocation Vary by Industry?

Asset allocation varies by industry as well as age. Technology billionaires hold about 70 percent of their wealth in public shares, the most of any industry, while real estate billionaires hold far more in private and property assets.

The variation in asset allocation by industry is as revealing as the variation by age, and the two are closely linked, since the youngest billionaires are concentrated in the most equity-heavy sector.

Technology billionaires hold about 70 percent of their wealth in public shares, the most of any industry, against about 40 percent for banking and finance and only about 20 percent for real estate billionaires.

The variation in allocation by industry, closely tied to the age profile of each sector, is one of the most useful ways of understanding why billionaire wealth is held so differently across the population.

The equity-heavy allocation of technology billionaires, whose wealth is the listed stock of their companies, is the single biggest reason young billionaires hold so much in public shares, since their wealth is the stock of their firms.

Technology leads: technology billionaires hold about 70 percent of their wealth in public shares, the most of any industry, against about 20 percent for real estate billionaires.

Billionaires in banking and finance, manufacturing and real estate hold more balanced allocations, with larger private and liquid shares, reflecting the different ways wealth is held across industries and the older age of those sectors billionaires.

The link between industry and allocation, with technology equity-heavy and real estate property-heavy, explains much of the variation by age, since the age profile of billionaires differs so sharply between sectors.

How Much Is in Property and Luxury?

Real estate and luxury assets, from property to art, cars and yachts, are a small share of billionaire wealth, about 4 to 5 percent across all age groups. This is far smaller than most people assume for the very wealthy.

The small place of real estate and luxury in billionaire wealth is one of the most surprising findings, running counter to the popular image of the super-rich and their yachts, jets and mansions.

At about 4 to 5 percent of wealth, real estate and luxury is by far the smallest of the four asset classes, a fraction of the public and private business holdings that dominate billionaire wealth.

The gap between the popular image of billionaire wealth, all yachts and mansions, and the reality of business holdings is one of the most instructive lessons in the whole of the asset-allocation data.

Despite their visibility, luxury assets such as art, yachts and jets make up only a few percent of billionaire wealth, a share our alternative assets coverage frames against the newer asset classes.

Business vs property: billionaires hold about three quarters of their wealth in business ownership and only about 5 percent in property, the reverse of ordinary households, who hold about half their wealth in property.

Real estate remains attractive to billionaires as a store of value and something tangible to pass on, but as a share of total wealth it is dwarfed by their public and private business holdings, which make up the great majority of their fortunes, as our top billionaire countries coverage shows for the largest holders.

The modest share of real estate and luxury, despite its high visibility, underlines how much billionaire wealth is working capital in businesses rather than assets held for enjoyment or display.

Billionaire Asset Allocation in Numbers

A few figures capture the picture. Billionaires under 50 hold about 63 percent of their wealth in public shares, against about 40 percent for those aged 50 and over, while private and liquid holdings rise with age.

These figures together show how billionaire wealth is actually held, and how it shifts from the concentrated equity of the young founder to the diversified holdings of the older, established billionaire.

Taken together, the figures describe how billionaire wealth is held and how it changes with age, from the concentrated equity of the young to the diversified holdings of the old. These figures together provide a rare window into how the very wealthiest people actually hold their money, correcting many of the assumptions that surround the lifestyles of the super-rich.

These figures matter because asset allocation shows how billionaire wealth is actually held, and how it shifts with age, a picture our wealth per adult by country and wealthiest women coverage complements.

Ownership dominates: public and private business holdings together make up about 73 percent of billionaire wealth, with liquid assets about 22 percent and real estate and luxury only about 5 percent.

Together they describe a billionaire class whose wealth is overwhelmingly business ownership, concentrated in listed shares among the young and more diversified among the old. For now, the breakdown shows a billionaire class whose wealth is overwhelmingly business ownership, held as concentrated public equity by the young and as a diversified mix by the old.

Billionaire Wealth by Asset and Age: The Big Picture

Taken together, the breakdown of the average billionaires wealth by asset and age in 2026 shows a sharp shift from concentrated public shares among the young to a diversified mix among the old, a clear pattern across the billionaire class.

The crossover with age: public shares fall from about 63 percent of wealth for the young to about 40 percent for the old, while diversified private and liquid holdings rise to make up the majority.

Whether the equity-heavy allocation of young billionaires proves lasting will depend on the technology sector, but for now billionaire wealth remains overwhelmingly business ownership, shifting toward diversification with age.
