The world’s richest people are wealthier now than they've ever been, and more billionaires have made it onto the 2025 World's Billionaires List than ever before, according to Forbes. This year, 18 Houston-based billionaires are among the richest people in the world, with hospitality honcho Tilman Fertitta leading as the richest Houstonian.

Fertitta, 67, ranked No. 220 overall with an estimated net worth of $11.3 billion, which steadily increased from his 2024 net worth of $9.4 billion.

In addition to owning the Houston Rockets, the busy billionaire owns Texas-based hospitality and entertainment corporation Landry's, and he authored a book about business leadership in 2019. He most recently was nominated as the new United States ambassador to Italy by President Donald Trump.

Ranking 248th overall is oil and gas chairman Richard Kinder. Forbes estimates his net worth at $10.6 billion, up from $8.1 billion in 2024.

Kinder cofounded pipeline giant Kinder Morgan in 1997, and stepped down as CEO in 2015, though he still retains his seat as chairman of the board. The company is the largest energy infrastructure firm in the U.S., Forbes says, and it owns 79,000 miles of pipeline.

New to the 2025 list is Perry Homes executive chair Kathy Britton, whose company has built over 65,000 homes across the U.S., according to Forbes. Her late father, Bob Perry, founded Perry Homes in 1967. Britton ranked No. 1408 with an estimated net worth of $2.6 billion.

Mercedes-Benz mega-dealer Joe Agresti is another newbie to the list, ranking No. 2790 with a net worth of $1.1 billion. He owns Dream Motor Group with former football coach Nick Saban.

14 additional Houston-area billionaires that made Forbes 2025 world’s richest list are:

  • Houston pipeline heir Randa Duncan Williams: ranked No. 307 with an estimated net worth of $9.3 billion, up from $7.7 billion in 2024. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 311th nationally. Each has an estimated net worth of $9.2 billion, up from $7.6 billion.

Elsewhere in Texas, Austin-based billionaire Elon Musk topped Forbes' list as the world's richest person in 2025. The Tesla and SpaceX founder knocked French luxury goods magnate Bernard Arnault down to second place this year.

Forbes declared Musk the first person to reach the $300 billion status. His current net worth stands at $342 billion, which is a staggering $147 billion more than his 2024 net worth.

"It’s another record-breaking year for the world’s richest people, despite financial uncertainty for many and geopolitical tensions on the rise," said Forbes senior editor of wealth Chase Peterson-Withorn. "And, from Elon Musk to Howard Lutnick and the other billionaires taking over the U.S. government, they’re growing more and more powerful."

In Dallas-Fort Worth, Walmart heiress Alice Walton became the wealthiest woman in the world in 2025. Forbes declared Walton's net worth at $101 billion, which is $28.7 billion more than her 2024 net worth of $72.3 billion. She is now one of 15 individuals to claim 12-figure fortunes, also known as the "$100 Billion Club."

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.
