• The Waltons have reclaimed the title of the world's wealthiest family
• The Walmart family fortune has grown by 66% since last year to a record $432 billion.
• Jim, Rob, Alice, and the other Waltons are richer than the royal families of Abu Dhabi and Qatar.

The Waltons are once again the world's wealthiest family, ranking ahead of Gulf royalty, luxury fashion houses, and industrial dynasties.

The heirs to the Walmart fortune have grown their wealth by 66% since last year to a record $432 billion as of December 5, meaning they've regained the No.1 spot on Bloomberg's annual list of the world's richest families.

That wealth figure exceeds the market value of some of America's biggest companies including Home Depot ($412 billion), Procter & Gamble ($402 billion), and Netflix ($396 billion).

Abu Dhabi's ruling family, the Al Nahyans, topped the ranking last year with an estimated $305 billion fortune that dwarfed the Waltons' $260 billion. The two clans switched places this year with the Al Nahyans now worth $324 billion, more than $100 billion less than the Waltons.

Qatar's ruling dynasty, the Al Thanis, placed third this year with $173 billion to their name. France's Hermès family, which includes the Birkin maker's artistic director and executive chairman, landed in fourth with $171 billion. Rounding out the top five were the Kochs, the legendary US industrialists worth an estimated $149 billion.

The richest families on the planet also include Saudi Arabia's rulers, candy dynasties Mars and Ferrero, and the Wertheimer family behind Chanel.

Family fortunes

Walmart founder Sam Walton's three surviving children — Jim, Rob, and Alice — have each grown about $43 billion richer this year, per the Bloomberg Billionaires Index.

The trio joined the $100 billion club in September and ranked among the 15 richest people on the planet as of December 12 with north of $112 billion to each of their names.

Lukas and Christy Walton, the son and widow of Sam's late son, John T. Walton, also feature on Bloomberg's rich list with net worths of about $40 billion and $18 billion each.

The five Waltons' combined fortune has ballooned by more than $150 billion this year, representing a big chunk of the 25 richest families' total wealth gain of $407 billion.

The Walton family's wealth bump has been fueled by a roughly 80% surge in the retailer's stock price this year. Sam Walton gave each of his four children a 20% stake in the family enterprise early on, and his three surviving kids each own upward of 11% of Walmart — now a company valued north of $750 billion — through a family trust. They've also raked in more than $15 billion from stock sales and dividends over the years, Bloomberg says.

• The world's 10 biggest wealth gainers have grown $790 billion richer in 2024.
• Elon Musk leads the list with a $257 billion gain that has boosted his net worth to $486 billion.
• Mark Zuckerberg, Jeff Bezos, Larry Ellison, and Jensen Huang are all up more than $70 billion.

Ten people have grown their personal fortunes by a combined $790 billion this year — a figure larger than the market value of Walmart ($767 billion).

The biggest wealth gainers of 2024 include Tesla CEO Elon Musk, Meta CEO Mark Zuckerberg, Amazon chairman Jeff Bezos, Oracle chairman Larry Ellison, and Nvidia CEO Jensen Huang, according to the Bloomberg Billionaires Index.

The buzz around artificial intelligence, a solid outlook for the US economy, and market expectations about Donald Trump's second term in office have boosted their companies' stock prices, benefiting them as major shareholders.

3. Jeff Bezos

Year-to-date wealth gain: $72.9 billion

Net worth: $250 billion

Ellison purchased more than 1.5% of Tesla prior to joining its board in December 2018, making him the electric-vehicle maker's second-largest individual shareholder after Musk. He's believed to have retained his stake, now worth upward of $20 billion, since resigning as a director in 2022.

5. Jensen Huang

Year-to-date wealth gain: $70 billion

8. Jim Walton

Year-to-date wealth gain: $45.1 billion

Source of wealth gain: Walmart stock

Jim Walton is the youngest son of Walmart founder Sam Walton and, like his siblings, one of the retailer's largest shareholders with an 11%-plus stake.

Walmart stock has climbed 82% this year, fueled by resilient consumer spending in the face of historic inflation and soaring interest rates in recent years. The surge led to Walton amassing a $100 billion fortune for the first time in September.

9. Alice Walton

Year-to-date wealth gain: $44.4 billion

Net worth: $114 billion

Source of wealth gain: Walmart stock

Alice Walton is the only daughter of Walmart founder Sam Walton.

She overtook L'Oréal heiress Françoise Bettencourt Meyers in August to become the world's richest woman.

10. Rob Walton

Source of wealth gain: Walmart stock

Rob Walton is the eldest son of Sam Walton and an heir to the Walmart fortune.

• On Wednesday, Gautam Adani was charged by US prosecutors in a massive bribery scheme.
• The charges have spurred an investor revolt and at least one customer to back out of major deals.
• Adani is the 2nd-richest person in India, behind Mukesh Ambani.

Gautam Adani, the second-richest person in India, is facing bribery charges in the US and business tumult globally.

Adani is the founder and chairman of the Adani Group, a multinational conglomerate with businesses spanning energy, mining, ports, and airports. The Adani Group owns India's largest commercial port and has a controlling stake in Mumbai's international airport.

On Wednesday, New York prosecutors said Adani executives paid hundreds of millions of dollars in bribes to the Indian government and hid them from US investors. The Adani Group called the allegations "baseless." 

The charges wiped out billions from Adani's and his brother's paper fortunes. Shares of companies related to Adani, including his flagship Adani Enterprises, Adani Green Energy, and Adani Ports and Special Economic Zone Ltd., crashed 20% in the first two hours of trade on Thursday, wiping out more than $30 billion.

The charges led to immediate business fallout. Following the news, Adani Green Energy canceled plans to raise $600 million in US dollar-denominated bonds, the company said in a statement to the National Stock Exchange of India. On Thursday, Kenya's president canceled deals with the Adani Group for its main airport and for power line construction. 

A short seller's report sent stocks down

The indictment isn't the first serious bout of trouble for Adani.

A 2023 report by Hindenburg Research, an investment-research firm and short seller, sent Adani's wealth on a downward spiral. In the report, which Hindenburg said took two years to compile, the short-seller accused the Adani Group of a "brazen stock manipulation and accounting fraud scheme." Adani companies' stocks tumbled but later recovered.

The Adani Group has said it was exploring legal action against Hindenburg and released a 413-page report which said that Hindenburg's claims were "nothing but a lie." It called Hindenburg's document a "malicious combination of selective misinformation and concealed facts relating to baseless and discredited allegations." 

Hindenburg criticized the group's response, saying it failed to address many of its questions.

Adani Group did not ultimately sue Hindenburg over the report.

From diamond sorter to tycoon

Adani was born in Ahmedabad, in the Indian state of Gujarat, in 1962. He dropped out of university after his second year studying commerce, according to Silicon India. He then turned to the diamond industry, first as a sorter and then as a trader in Mumbai.

After his brother purchased a plastic company, Adani started working with him and began importing PVC. In 1988, he set up Adani Enterprises.

Today, the Adani Group comprises 10 listed companies with a combined 46,000 employees.

The billionaire is a key ally of Prime Minister Narendra Modi, whose government has inked infrastructure and other deals with Adani's companies. Bloomberg deemed Modi "the foundation of the tycoon's empire."
