America's wealthiest billionaires are $1.2 trillion richer in 2025, bringing their collective worth to a staggering $6.6 trillion. And Houston's own Richard Kinder has become the richest billionaire in the city, according to the new Forbes 400.

The Kinder Morgan chairman is the 11th richest Texas resident and ranks as the 108th richest American. Kinder also dethroned Tilman Fertitta to claim the title as the wealthiest Houstonian.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies.

Kinder's wealth

The publication estimates Kinder's net worth at $10.6 billion, up from $8.1 billion last year. He also appears among Forbes' separate list of the richest billionaires in the world.

"It’s been a year unlike any we’ve seen in the four decades we’ve tracked America’s billionaire class,” said Forbes senior editor Chase Peterson-Withorn in a press release. "The super-rich at the very top are richer than ever — and between the White House and the booming stock market, they’re as powerful as they’ve ever been."

Kinder, 80, co-founded oil and gas pipeline firm Kinder Morgan in 1997, which is now known as one of the largest American energy infrastructure companies. He stepped down as CEO in 2015, though he still chairs the board of directors.

Kinder and his wife, Nancy, also founded Houston-based nonprofit the Kinder Foundation in 1997. The organization provides "major gifts to public causes with the intention of helping people realize healthy and rewarding lives," according to its website.

In May 2025, the Kinders pledged $150 million to Texas Children's Hospital and MD Anderson to create the Kinder Children's Cancer Center.

"Our philanthropic efforts center on supporting transformational projects in Houston, and this initiative exemplifies that mission in every way," said Kinder in a press release. "We were deeply impressed by the extraordinary leadership and unwavering commitment of both UT MD Anderson and Texas Children’s to pursue a bold, collaborative model of care. It is a rare and powerful moment when two leading organizations come together to create something entirely new – something capable of reshaping the future of pediatric cancer care."

The richest Houstonians

In all, 43 Texas billionaires made it on the 2025 Forbes 400 list, and 10 are based in the Houston metro.

Hospitality honcho Fertitta, 68, is the second-richest billionaire in Houston, and his net worth has jumped from $10.1 billion last year to $11 billion in 2025. He owns the Golden Nugget Casinos, the Houston Rockets, Texas-based restaurant and entertainment company Landry's, and also serves as the U.S. Ambassador to Italy.

"Serving as President Trump's ambassador to Italy 'is a real job,' says Fertitta, who personally oversaw the renovation of Villa Taverna, the ambassador's residence in Rome," Forbes wrote in his profile.

Fertitta most recently put his ritzy 250-foot-long superyacht on the market for about $192 million, with Forbes saying he "has a bigger one on order."

Here's how the rest of Houston's billionaires fared on this year's list:

  • Oil tycoon Jeffery Hildebrand ties for No. 123 nationally with an estimated net worth of $10 billion. Last year: $7.6 billion.
  • Toyota mega-dealer Dan Friedkin ranks 128th nationally with an estimated net worth of $9.7 billion. Last year: $7.6 billion.
  • Houston pipeline heir Randa Duncan Williams ranks 130th with an estimated net worth of $9.5 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 135th nationally. Each has an estimated net worth of $9.4 billion. Scott Duncan ranks No. 141 with a $9.2 billion estimated net worth.
  • Houston Texans owner Janice McNair ranks 201st nationally with an estimated net worth of $7.3 billion. Last year: $6.2 billion.
  • Energy exploration chief exec George Bishop of The Woodlands ranks No. 325 with an estimated net worth of $4.7 billion. Last year: $5 billion.

Richest billionaires elsewhere in Texas

The richest person in America in 2025 is none other than Austin-based Elon Musk. Musk, 54, saw his net worth skyrocket to $428 billion this year, or $184 billion more than his 2024 net worth. He claimed the No. 1 spot for the fourth time.

Walmart heiress Alice Walton of Fort Worth was dubbed the wealthiest woman in America for 2025. Walton, 75, simultaneously holds the title as the richest woman in the world. Forbes estimates Walton's net worth at $106 billion (up from $89.2 billion last year) and proclaims her as the first female centibillionaire (a person with a 12-digit fortune) in America. Now that's wealth.

"Tariffs. Inflation. Slowing employment. None of it has hit the fortunes of America’s billionaires," Forbes said. "A decade ago, when it took $1.7 billion to make The Forbes 400, a net worth of $3.8 billion was comfortably within the top half of the ranking — now that lofty sum is the minimum required."

Local billionaires Jeffery Hildebrand and Tilman Fertitta top list of richest in Houston, per Forbes

meet the billionaires

According to Forbes, half of all of the world’s billionaires are less wealthy than they were in 2022. But that’s not the case for most Houston-area billionaires like oil tycoon Jeffery Hildebrand, who was named the richest man in the city.

The 2023 edition of Forbes’ World’s Billionaires List declared Hildebrand’s net worth at $10.2 billion, placing him as the 171st richest person in the world. His fortune is $2.7 billion higher than his 2022 net worth of $7.5 billion, when he ranked No. 316 on the list.

As CultureMap reported, in 2015, Hildebrand made headlines when he gifted each of his 1,381 employees a $100,000 holiday bonus.

Houston’s favorite hospitality mogul and Rockets owner Tilman Fertitta is the city’s second-richest man, with his net worth climbing up to $8.1 billion. He ranked No. 256 on Forbes’ list, substantially higher than his No. 471 rank in 2022 when his net worth was $5.6 billion. Fertitta is surely living life to the fullest after hosting Miami rapper Pitbull at his San Luis Salute celebration earlier this year.

His Forbes rank is No. 1434.An honorable mention (and billionaire newbie) is Amy Adams Strunk, the controlling owner of the Tennessee Titans and daughter of Houston Oilers owner Bud Adams. She has a residence in Waller (about 40 miles northwest of Houston) and her net worth is $1.7 billion — making her No. 1725 on the list.One name missing from Forbes 2023 report is software entrepreneur Robert Brockman, who passed away last August. Brockman fell from grace after he was charged in the largest tax fraud case in U.S. history in 2020. Forbes listed his 2022 net worth at $4.7 billion. He is survived by his wife, son, and two grandchildren.Elsewhere in Texas, Elon Musk reigns as the richest man in the state and in its capital city of Austin with a net worth of $180 billion. The Tesla and Space-X founder is the second richest person in the world, wedging his way between No. 1 Bernard Arnault of France (overseer of the LVMH empire of 75 fashion and cosmetics brands, including Louis Vuitton and Sephora), with a net worth of $211 billion; and No. 3 Jeff Bezos, the American Amazon founder, worth $114 billion.

Dallas Cowboys owner Jerry Jones'$13.3 billion net worth won him the title of Dallas' richest person, and the 12th richest sports owner on Forbes' "World's Richest Sports Owners 2023." His net worth is up from $10.6 billion last year.

The Fort Worth-based Walmart family heiress Alice Walton earned a spot on Forbes’ list as the third richest woman in the world. Her fortune is pegged at $56.7 billion, down slightly from $65.3 billion last year.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

Intuitive Machines forms partnership with Italian companies for lunar exploration services

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
