From golfing with Donald Trump at the Mar-a-Lago Club estate, to lounging on yachts and boarding private jets, AI billionaires are increasingly emerging as the new jet-setting elite.

Tech trailblazers live in sprawling mansions in Palm Beach, Miami and Hawaii, enjoying the luxurious lifestyle afforded by their contributions to innovation.

Fuelled by the AI boom, a new generation of power brokers has emerged, mirroring the meteoric rise of entrepreneurs in the late-1990s dot-com frenzy.

The sector is fast becoming the defining technology of our time with UN Trade and Development reports projecting the global AI market will soar to $4.8trillion by 2033 – a 25-fold increase in just a decade.

And for those leading the tech revolution comes a life of ultimate luxury, from mega-yachts and lavish holidays to multi-million-pound estates.

xAI founder Elon Musk owns a fleet of private Gulfstream jets and vintage cars while Ian Hathaway, who controls OpenAI's Startup Fund, was recently spotted hand in hand with former tennis star Eugenie Bouchard on a sunny getaway in Lake Como.

And it's not just men on top: 31-year-old Lucy Guo unseated Taylor Swift as the world's youngest self-made woman billionaire in 2025.

Now, her Instagram is full of glamorous snaps of the American sunning herself on the beach, walking catwalks and jet-setting across the world on extravagant holidays.

San Francisco, meanwhile, has seen an astonishing housing boom supercharged by AI with the median sale price in the city as of May 2026 at a record high of $1.76million.

Ian Hathaway began his career as an economist but he now leads the investment fund of US AI research organisation OpenAI, the maker of ChatGPT.

Having worked for the fund since 2021, Hathaway took over the reins from CEO Sam Altman in 2024 after he stepped down.

The $175million OpenAI Startup Fund invests in early-stage AI startups where it believes AI can have a transformative effect – including in healthcare, law, education and energy and infrastructure.

Before joining OpenAI, Hathaway was an investor at Haystack, a San Francisco-based seed-stage VC firm, which made early investments in companies such as Instacart and Doordash, as well as cloud infrastructure company HashiCorp, petcare service provider Wag and equity management platform Carta.

In June, he was listed in Global Corporate Venturing's 2026 Powerlist – representing 100 individuals spearheading the future of the corporate venturing industry.

Weeks later, the investor was photographed with tennis glamour girl Eugenie Bouchard in northern Italy.

The Canadian sports star, 32, was dressed in a cream minidress as she relaxed in the sunshine with the venture capital investor on the shores of Lake Como.

Bouchard was seen hand-in-hand with Hathaway as they headed out for a stroll after canoodling together in the swimming pool at Villa D’Este, a luxurious resort.

It came after she wrapped a much-praised debut in broadcasting at the Wimbledon Championships.

Bouchard, who retired from professional tennis in 2025 following the Canadian Open, shared several photos and videos on Instagram from her Italian trip – though Hathaway doesn’t make any appearances in the posts.

The Instagram-loving 'world's youngest self-made female billionaire'

Lucy Guo, a computer science college dropout, has an estimated net worth of $1.5billion after cofounding data labelling giant Scale AI with Alexander Wang in 2016.

Guo left the business two years later in 2018 holding on to much of her stake, and that same year she made the Forbes' 30 Under 30 list.

In 2022, she founded Passes – a platform for influencers and celebrities to connect with fans that's similar to Patreon and OnlyFans – raising $50million from investors.

She owns three main residential properties: a newly constructed mansion in LA’s Hollywood Hills, overlooking the Sunset Strip, for nearly $30million, a $6.7million condo in Florida, and a farmhouse-style home in LA, which she secured at $4.2million.

Her mansion in the Hollywood Hills has a cantilevered glass living room, an infinity pool with a spa, a sunken fire pit, and a 5,000 square foot garden, according to the property listing.

She posts dazzling photos to her 208,000 Instagram followers of her attending exclusive parties, DJing at festivals and boarding private jets.

'Honestly, I still feel the same as that little girl, like my life pre-money and post-money, it hasn’t really changed that much,' Ms Guo told CNBC Make It. 'I still find deals like I pretty much only order buy-one-get-one-free on Uber Eats.'

While Guo does enjoy some downtime, extended time off from her company is not ever on the cards.

'I've never really had a real vacation,' she told Fortune. 'Even when I'm on vacation I'm working at least eight hours per day.'

Outside of work, Guo is a fitness fanatic and can often be found keeping fit at Barry's Bootcamp, a boutique, high-intensity workout class which she attends twice a day.

In April 2025, she celebrated reaching a mind-blowing 3000 classes and credited her 'discipline' over prioritising sleep as the secret to her achievement.

The AI mogul who dumped his wife for a younger woman

Chey Tae-won is a South Korean billionaire businessman and the chairman of SK Group, one of Korea's largest conglomerates with interests in telecom, semiconductors, chemicals and energy, among others.

With a net worth of $5.3billion, he is South Korea's ninth richest person.

But the dramatic downfall of his marriage meant he immediately entered the history books of his country for a reason other than his business success.

He was the billionaire atop blockbuster memory chip maker SK Hynix.

She was the daughter of a past president.

Together, Chey and Roh Soh-yeong were South Korea’s romanticised ‘marriage of the century' for 27 years.

Last week, Chey was ordered to pay his ex-wife 944bn won (£489million) in a case that local media dubbed the 'divorce of the century'.

It was the fallout from a marital betrayal from more than a decade ago, when the AI mogul penned a scandalous three-page letter to a South Korean newspaper.

In the confession that shook the nation, he described how he loved another woman and had fathered a child with her.

This picture taken on June 26 shows Roh Soh-yeong, director of Art Center Nabi, arriving at a court to attend her retrial regarding the division of assets with her former husband SK Group Chairman Chey Tae-won at the Seoul High Court in Seoul

In court papers cited by local media, he said he didn’t believe his marriage could be redeemed and quoted the opening of Leo Tolstoy’s novel Anna Karenina: the Russian tragedy centred around an infidelity: 'Happy families are all alike; every unhappy family is unhappy in its own way.'

He married Kim Hee-young – the woman 15 years his junior with whom he had already fathered a child – in 2015.

Roh later sued Kim over the affair, and a court ordered Chey and Kim to jointly pay her roughly $1.5million in damages.

The tech mogul posts Instagram photos of himself to his almost 90,000 followers, posing with Silicon Valley chief executives such as Jensen Huang, OpenAI CEO Sam Altman and Microsoft CEO Satya Nadella.

Chey, who goes by 'Tony' in the West, enjoyed a golfing session at Palm Beach's Mar-a-Lago before a meeting with President Donald Trump last autumn, while Joe Biden had called him a 'pal' during a 2022 visit.

The cash award to Roh is a record for South Korea, even though substantially lower than a settlement of 1.38 trillion won ordered by the appeals court in 2024.

Fund managers and analysts said it meant Chey may still need to sell shares in units of SK Group or use them as collateral to raise funds for payment, but probably would not affect management control of the conglomerate.

'This likely won't affect management control of SK Group,' said Park Ju-gun, head of corporate analysis firm Leaders Index.

SK Group's international profile has soared on the back of the artificial intelligence boom.

Its chip affiliate, SK Hynix, has become a key supplier of high-bandwidth memory (HBM) chips used with Nvidia's AI processors, making the company one of the biggest beneficiaries of surging demand for advanced semiconductors.

Elon Musk's pronatalist fantasy and his love of private jets

If in business Elon Musk seeks endless innovation and danger, his private life is defined by the same turbulence and chaos.

Musk has welcomed 14 children with four different partners: Justine Wilson, Grimes, Shivon Zilis and St. Clair.

Beginning with the arrival of his firstborn son in 2002, who tragically passed away at ten months old, the tech billionaire's children are: Nevada, Vivian, Griffin, Kai, Saxon, Damian, X Æ A-Xii, Exa, Strider, Azure, Techno, Arcadia, Seldon Lycurgus, and Romulus.

Following the death of Nevada, Musk and his then-wife Wilson subsequently welcomed twins Vivian and Griffin, followed by triplets Kai, Saxon, and Damian.

After their divorce in 2008, Musk later welcomed three children with Grimes, four children with former Tesla employee Zilis, and, most recently, a son named Romulus with Ashley St. Clair.

His eldest daughter, Vivian, has admitted she has a hard time keeping track of just how many siblings she has.

'I will say I do not actually know how many siblings I have, if you include half-siblings,' the model told Teen Vogue, adding that she is on 'good terms' with those she does know, despite having a difficult relationship with her father.

The tech mogul, who has a net worth of $719billion, operates a fleet of four private jets and once owned seven homes.

In 2020, however, Musk took to X to announce that he was 'selling almost all physical possessions' and 'will own no house'.

He sold all seven of his homes in California for $128million, and said he would reside in a small rental home in Texas, believed to be worth $50,000.

Now, the SpaceX founder has made his base in multiple traditional, stucco houses near each other in a nondescript, upscale suburban area about a 15-minute drive from downtown Austin.

The pronatalist CEO bought the properties intending to create a compound where the mothers of his children could live with their offspring – but many of them have refused to stay there.

Nvidia CEO Jensen Huang's Hawaii hideaway

In 2025, Jensen Huang's Nvidia became the first company in the world to reach a valuation of $5trillion.

Nvidia is the computer chip designer spearheading the artificial intelligence revolution.

Its technology – once used to create graphics for video games – is capable of training AI models to perform tasks like image, facial and speech recognition as well as generating text for chatbots like ChatGPT.

He is the seventh richest person in the world with a net worth of $172.6billion, according to Forbes.

It marks an astonishing reversal of fortune for a shy former Denny's worker who was bullied at his Kentucky school after arriving from Thailand when he was nine.

But then everything about Huang's story is astonishing and showcases the powerful potential of when hard work, perseverance and good luck combine.

Today, the 63-year-old father of two lives with his wife Lori on San Francisco's Billionaires' Row where homes cost tens of millions of dollars and you can count tech giants Larry Ellison and David Sachs as neighbours.

The 11,400-square-foot, seven-bedroom property boasts panoramic views of the city's Gold Coast and has an estimated worth of $38million.

His property portfolio totals approximately $53million across three dwellings, including a $6.9million estate in Los Altos Hills, and an $8million compound in Maui.

As his wealth has ballooned, Huang too has transformed. Once a geeky, unassuming computer scientist, he is now a Silicon Valley rockstar – armed always in his trademark black leather jacket and with a tattoo of the Nvidia logo on his left arm.

The OpenAI CEO worth $3.3billion

Sam Altman, the 41-year-old CEO of OpenAI and a prolific venture investor, has a net worth of $3.3billion.

He bought a luxury mansion in San Francisco's Russian Hill neighbourhood for $27million in 2020, though he would later sue its developers and contractors for issues such as 'substandard work' and 'financial embezzlement', Realtor.com reported.

He also purchased three more lots around the six-bedroom, seven-bathroom San Francisco property.

The LLC he bought the mansion through said it was 'reported to be the most expensive home listing in San Francisco history', when it was first put on the market.

The billionaire also owns a 950-acre ranch in Napa County.

He bought the property for $15.7million in 2020.

The total value of his real estate portfolio is $124million.

In January 2024, Altman married his partner, Oliver Mulherin, in a seaside ceremony.

In April this year, a 20-year-old man approached the gate of his San Francisco home and hurled a molotov cocktail at the building before fleeing.

The suspect, Daniel Moreno-Gama, was arrested less than two hours later while allegedly trying to break into the headquarters of OpenAI with a jug of kerosene, a lighter and an anti-AI manifesto.

Federal and California state authorities subsequently charged Moreno-Gama with a range of crimes, including attempted arson and attempted murder.

He pleaded not guilty in May and his preliminary hearing is scheduled for August 19 after he requested a voluntary extension.

The Facebook founder worth $232billion

A 19-year-old Mark Zuckerberg first started Facebook in 2004 for students to match names with photos of classmates.

From his Harvard dorm room, the businessman managed to steer the platform from a university-based social site to the largest social network in the world.

Since then, Zuckerberg has rebranded Facebook Inc. into Meta Platforms Inc., with a focus on building the metaverse and developing major AI initiatives.

The Facebook boss has been investing billions of dollars in data centres and the best research talent in a bid to dominate the superintelligence space, and he even created an AI version of himself with the intention to offer 'conversation and feedback' to his staff.

As he continues his battle to conquer the world of AI, the billionaire has also been developing his vast property portfolio.

With an estimated net worth of $232billion, Zuckerberg already owns homes in Lake Tahoe, Palo Alto and Kauai and is reported to be developing a sprawling $170million mega mansion in Florida.

And when he is not working, the tech-entrepreneur has been known to take up extravagant hobbies.

Zuckerberg has been honing his hydrofoiling skills, having been pictured multiple times having fun in the water on his $12,000 Efoil board, which allows users to glide above the water at speeds up to 25mph.

He also actively trains in martial arts. He is a blue belt and trains with top-tier coaches and fighters, notably earning gold and silver medals in his competitive Brazilian jiu-jitsu debut.
