The richest people in the world's richest countries, ranked

The wealthiest names across the world's top economies

The G20 brings together the largest economies around the globe though, despite the name, it actually comprises 19 nations plus the EU and African Union. Needless to say, many of the planet's wealthiest individuals hail from G20 member states, from tech titans and retail moguls to mining magnates and energy barons.

Click or scroll on to find out who tops the rich list in each of the world's economic powerhouses, based on the Forbes Real-Time Billionaires List at time of publication.

All dollar amounts in US dollars

Argentina. Marcos Galperin, net worth: $7 billion

Buenos Aires-born entrepreneur Marcos Galperin is the founder and CEO of MercadoLibre, Latin America's answer to eBay. The e-commerce and fintech giant operates in 18 countries across the region and generates annual revenues of more than $26 billion.

Argentina currently has the weakest economy in the G20, so it’s perhaps to be expected that it also has the group’s lowest-net-worth richest person. Even so, Galperin has built an impressive fortune since launching MercadoLibre in 1999, with the self-made tech tycoon now worth an estimated $7 billion.

Türkiye. Hamdi Ulukaya, net worth: $13.5 billion

Türkiye’s wealthiest person made his fortune in the US selling Greek yogurt. The entrepreneur bought a struggling dairy factory in Upstate New York in 2005 and launched the Chobani brand two years later, helping to popularise the rich, thicker style of yogurt across the country and earning him the title of 'America's yogurt king.'

Ulukaya, who owns 65% of the company, saw his net worth surge last year after Chobani was valued at $20 billion, stealing candy king Murat Ülker's crown as the world's richest Turk.

South Africa. Johann Rupert and family, net worth: $14.5 billion

While the current US administration is pushing for South Africa to be removed from the G20, the country remains the bloc's only African member. Its richest person is Johann Rupert, chairman of Swiss luxury goods group Richemont, the company behind high-end brands including Cartier and Montblanc.

Rupert built much of his fortune through the luxury giant, which was formed in 1998 from assets linked to Rembrandt Group, the conglomerate founded by his father Anton Rupert in the 1940s.

Saudi Arabia. Prince Alwaleed Bin Talal Alsaud, net worth: $19.4 billion

Saudi Arabia's richest person is investor Prince Alwaleed Bin Talal Alsaud, who amassed his riches through investment behemoth Kingdom Holding. Through the firm he has taken stakes in a number of major companies, including the Four Seasons hotel chain, X, xAI, and Snapchat.

The royal's wealth peaked at $22.6 billion in 2015. But his wings were clipped during Saudi Arabia’s 2017 anti-corruption crackdown, when he was detained for months. He was dropped from the Forbes list in 2018 but finally made a comeback last year after returning to favor at home.

UK. Michael Platt, net worth: $20.9 billion

Far from a household name, publicity-shy Michael Platt supplanted Ineos founder Jim Ratcliffe last year to become the UK's richest person.

Dubbed the 'invisible billionaire,' the math and trading whizz discreetly co-founded investment firm BlueCrest Capital Management in 2000 after nearly a decade at JP Morgan. He then built it into one of the world's most successful hedge funds, delivering stellar returns and managing $35 billion in assets at its peak.

South Korea. Jay Y Lee, net worth: $24.7 billion

Fittingly, South Korea's wealthiest individual leads the nation's biggest and most successful conglomerate.

Samsung boss Jay Y Lee was convicted of bribery and embezzlement in 2017 and went on to serve an 18-month prison sentence. But he was fully pardoned in 2022 and remains in control of the family business, along with his enormous fortune.

Australia. Gina Rinehart, net worth: $25.2 billion

Mining magnate Gina Rinehart is the only woman who ranks as the richest person in a G20 country. A formidable business player, she transformed her late father's struggling iron ore company Hancock Prospecting into a hugely profitable business, raking in billions in the process.

Rinehart is also Australia's largest private landowner and one of the country's leading cattle producers.

Indonesia. Prajogo Pangestu, net worth: $26 billion

The son of a rubber trader, Prajogo Pangestu started out in the timber business in the late 1970s. His company Barito Pacific Timber went public in 1993 and later rebranded as Barito Pacific as it diversified beyond logging.

Pangestu's wealth spiked in 2023 after he listed coal miner Petrindo Jaya Kreasi and renewable energy firm Barito Renewables Energy. The group also controls petrochemicals giant Chandra Asri, one of Indonesia's largest integrated petrochemical producers.

Brazil. Eduardo Saverin, net worth: $35.7 billion

Eduardo Saverin co-founded Facebook with Harvard classmate Mark Zuckerberg in 2004 and still derives most of his wealth from his small but valuable stake in the social media giant's parent company Meta.

Although he's officially Brazil's richest person, Saverin actually lives in Singapore, where he works as a venture capitalist. In 2015 he launched B Capital, which now manages more than $7 billion in assets.

Russia. Alexey Mordashov and family, net worth: $36.9 billion

Russia is effectively frozen out of the global get-togethers but remains a G20 member. Unsurprisingly, its richest person is a pro-Putin oligarch.

Alexey Mordashov built his fortune around steel giant Severstal, where he still holds a controlling stake. After sanctions were imposed in 2022, he moved swiftly to transfer ownership of some of his overseas assets, including stakes in travel firm TUI and gold miner Nordgold, helping him hold on to a significant slice of his fortune.

Italy. Giovanni Ferrero, net worth: $48.2 billion

Italy's richest person by a wide margin, Giovanni Ferrero was catapulted into the billionaire club when his father Michele passed away in 2015, leaving him with 75% of the eponymous family confectionery business. Having brought the world Nutella, Kinder Surprise, and Ferrero Rocher, Ferrero Group now encompasses Nestle's US confectionery business and breakfast cereal titan WK Kellogg.

Ferrero currently serves as the company's executive chairman, having stepped down as CEO in 2017.

Japan. Tadashi Yanai and family, net worth: $57.9 billion

Heading up Japan's rich list is Tadashi Yanai, the founder of Fast Retailing, which is the parent company of global fast-fashion chain Uniqlo.

Fast Retailing has also swooped up a bevy of top brands over the years, from Helmut Lang and Theory to J Brand and Comptoir des Cotonniers.

Canada. Changpeng Zhao, net worth: $65.2 billion

Born in China and raised in Canada after emigrating there as a child, Changpeng Zhao, aka CZ, is crypto's richest tycoon. The founder of Binance, the world's largest crypto exchange, CZ has overtaken long-time Canadian rich list leader, media mogul David Thomson.

The blockchain pioneer stepped down as Binance CEO in 2023 following a US investigation. He later served four months in prison after pleading guilty to anti-money laundering violations, but received a full pardon from President Trump in October 2025.

Germany. Dieter Schwarz, net worth: $66.4 billion

Germany's wealthiest person is reclusive retail mogul Dieter Schwarz, the man behind discount supermarket giants Lidl and Kaufland. Together they form the Schwarz Group, one of the world's largest retail empires, which generates more than $160 billion in annual revenue.

Schwarz inherited the business from his father Josef. He opened the first Lidl store in 1973 and guided the budget chain's extraordinary expansion every step of the way. Not much is known about Schwarz's personal life and verified images of him are scarce.

China. Zhang Yiming, net worth: $69.3 billion

Software engineer Zhang Yiming co-founded ByteDance in 2012, launching the company from a modest Beijing apartment and turning it into one of the world’s most influential tech firms. Its flagship platform TikTok has become a global phenomenon, attracting more than a billion users and reshaping the social media landscape.

Zhang stepped away from the company's leadership in 2021 but remains its largest individual shareholder. He now lives in Singapore.

India. Mukesh Ambani, net worth: $96.8 billion

Asia's richest person as well as India's number one, Mukesh Ambani holds a 42% stake in Reliance Industries, a monster conglomerate with interests in oil, retail, media, plus a whole lot more besides.

Ambani made global headlines in 2024 for bankrolling his son Anant's star-studded nuptials to heiress Radhika Merchan to the tune of $600 million. The tycoon is also famed for his Mumbai skyscraper home, which is reportedly valued at $2 billion.

Mexico. Carlos Slim Helú and family, net worth: $119.1 billion

Mexico's wealthiest individual was also the world's richest person from 2010 to 2013, replacing Bill Gates at the top of the Forbes list.

Together with his family, Carlos Slim Helú owns 76% of sprawling conglomerate Grupo Carso. It counts mobile telecoms titan América Móvil among its extensive portfolio, which also includes everything from retail concerns to construction companies.

France. Bernard Arnault and family: $157.3 billion

Bernard Arnault heads LVMH, which he formed in 1987.

Europe's second most valuable company after chip industry supplier ASML, the luxury goods juggernaut boasts scores of distinguished high-end brands, ranging from Louis Vuitton and Christian Dior to Moët & Chandon and Tiffany & Co. Arnault also has interests in the likes of Netflix and ByteDance via his holding company Agache.

USA. Elon Musk, net worth: $831 billion

Well on the way to becoming the first trillionaire, South Africa-born Elon Musk is by far the richest person in the US, and the world.

The serial entrepreneur owns or runs a sprawling business empire spanning electric cars, space travel, artificial intelligence, and social media. But he's also no stranger to controversy, from his polarizing role in DOGE to his flirtation with the far right. Incidentally, Musk is a regular at G20 gatherings, though not always a welcome guest.
