Missouri has the Busches. Nebraska has the Buffetts. New York has the Hearsts. These are among the best-known wealthy families in the U.S.

Lesser-known nationally but well-known in Texas is the Duncan family of Houston, identified by FamilyMinded.com as the richest family in Texas. The website, which rounded up a list of the richest family in each state, pegs the family's estimated net worth at $26 billion; Forbes puts it at $25.6 billion.

The Duncan family comprises the four children of the late pipeline mogul Dan Duncan.

The children — Dannine Avara, Scott Duncan, Milane Frantz, and Randa Williams — inherited a tax-free $10 billion share of their father's estate following his death in 2010, when the so-called "death tax" had temporarily been repealed, according to Forbes. Each of them has an estimated net worth of $6.4 billion, Forbes says.

Williams is perhaps the most visible of the four Duncan heirs.

Williams is the only Duncan sibling who's involved in running the family business. She is chairwoman of Houston-based Enterprise Products Partners LP, the pipeline company that her father founded in 1968. Last year, the company posted revenue of $36.5 billion. In June, Williams made a big splash with her purchase of Austin-based Texas Monthly magazine.

While the Duncans are worth close to $26 billion, their wealth doesn't come close to that of Alice Walton of Fort Worth, the richest person in Texas. Forbes estimates her net worth at $52.4 billion.

FamilyMinded.com lists Alice Walton and her fellow heirs to the Walmart fortune as the richest family in Arkansas (where Walmart is based), with an estimated net worth of $163 billion. They're also the richest family in the U.S.

5 Texas entrepreneurs rank among Forbes' richest self-made women

Must be the money

It's common knowledge Houston Rockets owner Tilman Fertitta and Gulf States Toyota owner Dan Friedkin rank among the wealthiest people in Texas. But did you know that five other entrepreneurs — collectively worth more than $4 billion — stand among the richest self-made women in the country?

Billionaire Thai Lee and millionaires Kendra Scott, Kathleen Hildreth, Whitney Wolfe Herd, and Suzy Batiz appear on Forbes magazine's new list of America's 80 richest self-made women — women who garnered wealth on their own, rather than by inheriting or winning it. And they're in great company, joining the likes of Taylor Swift, Oprah Winfrey, Kylie Jenner, Rihanna, Madonna, Celine Dion, and Beyoncé.

Thai Lee, with an estimated net worth of $3 billion, appears at No. 5 on the Forbes list. She is president and CEO of SHI International Corp., a provider of IT products and services whose more than 17,000 customers include AT&T and Boeing. Revenue at the New Jersey-based company hit $10 billion in 2018; more than 4,000 people work at SHI. Austin is home to SHI's corporate call center and is the hub for its sales division catering to small and midsize businesses.

"In early 2015, we mapped a five-year goal to reach $10 billion in revenue by the end of 2019. Through the hard work of our employees, the strength of our partnerships, and our ability to discern and solve our customers' most pressing IT and business challenges, we reached that goal 12 months early," Lee says in a February release.

At No. 40 on the list, with an estimated net worth of $550 million, is Kendra Scott. She is founder and CEO of Kendra Scott Design Inc. Annual sales at the Austin-based jewelry company hover around $360 million.

In 2017, Boston-based private equity firm Berkshire Partners invested in Scott's company at a valuation of more than $1 billion. Scott started the company in 2002 in the spare bedroom of her home. Today, Scott's business operates 100 jewelry stores, runs massive e-commerce and wholesale units, and employs more than 2,000 people. Last year, the company opened its flagship store on South Congress Avenue.

"There were so many ups and downs through this journey. There were many times that I thought I was going to lose my business. I had no investment capital. I was carrying it all on my shoulders — bootstrapping it, literally," Scott told CNN in 2018.

Kathleen Hildreth, co-founder of aviation-maintenance company M1 Support Services, appears on the list at No. 57, with an estimated net worth of $370 million. She is a West Point graduate and Army veteran who served as a helicopter pilot. Before M1 Support, she worked with defense contractors, including Lockheed Martin and DynCorp. Hildreth calls Aubrey, Texas, in the DFW area, home.

"Anything in the government's [aircraft] inventory, we do work on," Hildreth told Forbes. "You name it." Forbes adds, "The U.S Air Force, U.S. Army, U.S. Navy, and NASA are all clients of M1 Support, which relies entirely on the federal government for business. Most of its revenues come from maintaining military aircraft, including fighter jets such as F15s, F16s, and A10 Thunderbolts."

The fourth Texas entrepreneur on the list is Whitney Wolfe Herd, founder and CEO of Austin-based Bumble Trading Inc., developer of the Bumble dating app for women, and the related Bumble BFF friend-finding app and Bumble Bizz networking app. Herd launched Bumble in 2014 after co-founding dating app Tinder. With an estimated net worth of $290 million, Herd claimed the No. 72 spot on the Forbes list. This is her first year to be ranked.

Bumble counts more than 60 million users in 150 countries. The company's estimated annual revenue totals $175 million, according to Forbes. Russian billionaire Andrey Andreev is the majority owner of Bumble.

"I want to take this sucker around the planet," Herd told Marie Claire last year about the future of Bumble. "Then, who knows, maybe we'll work with [Jeff] Bezos and [Elon] Musk and take it beyond."

At No. 77, with an estimated net worth of $270 million, is Dallas' Suzy Batiz, founder of Poo-Pourri, the before-you-go toilet spray available at major retailers. More than 60 million bottles have sold since the company's founding in 2007; Pou-Pourri is now expanding into shoe and pet odors and a cleaning line.

Asked in 2016 what the riskiest thing was she had ever done professionally, Batiz said not selling her company or taking on investors.

"I had no idea if it was going to work out. It's like being on a game show," she told Forbes. "They hand you the big briefcase and you think, 'You can take this thing of money, or you can gamble and try to stay in the game.' Somehow I knew that my baby, the company, was very similar to a child. It just wasn't ready to be released into the world yet without me."

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.

Houston hospitals win $50M grant for ibogaine addiction treatment research

ibogaine funding

The Texas Health and Human Services Commission has awarded $50 million to UTHealth Houston in collaboration with The University of Texas Medical Branch at Galveston (UTMB Health) to co-lead a multicenter research trial to evaluate the effect of ibogaine, a powerful psychoactive compound, on patients suffering from addiction, traumatic brain injury and other behavioral health conditions.

The funding will establish a two-year initiative—known as Ibogaine Medicine for PTSD, Addiction, and Cognitive Trauma (IMPACT)—and a consortium of Texas health institutions focused on clinical trials and working toward potential FDA-approved treatments.

The consoritum will also include Texas Tech University, Texas Tech University Health Sciences Center El Paso, The University of Texas at Austin, The University of Texas Health Science Center at San Antonio, The University of Texas at Tyler, The University of Texas Rio Grande Valley, Texas A&M University, The University of North Texas Health Science Center, Baylor College of Medicine and JPS Health Network in Dallas.

Ibogaine is a plant-based, psychoactive substance derived from the iboga shrub. Research suggests that the substance could be used for potential treatment for patients with traumatic brain injuries, which is a leading cause of post-traumatic stress disorders. Ibogaine has also shown potential as a treatment for addiction and other neurological conditions.

UTHealth and partners will focus on ways that ibogaine can treat addiction and associated conditions. Meanwhile, UT Austin and Baylor College of Medicine will concentrate on using it to treat traumatic brain injury, especially in veterans, according to a news release from the institutions.

The consortium will also support drug developers and teaching hospitals to conduct FDA-approved clinical trials. The Texas Health and Human Services Commission will oversee the grant program.

“This landmark clinical trial reflects our unwavering commitment to advancing research that improves lives and delivers the highest standards of care,” Dr. Melina Kibbe, UTHealth Houston president and the Alkek-Williams Distinguished Chair, said in the news release. “By joining forces with outstanding partners across our state, we are building on Texas’ tradition of innovation to ensure patients struggling with addiction and behavioral health conditions have access to the best possible outcomes. Together, we are shaping discoveries that will serve Texans and set a model for the nation.”

The consortium was authorized by the passage of Senate Bill 2308. The bill provides $50 million in state-matching funds for an ibogaine clinical trial managed by a public university in partnership with a drug company and a hospital.

“This is the first major step towards the legislature’s goal of obtaining FDA approval through clinical trials of ibogaine — a potential breakthrough medication that has brought thousands of America’s war-fighters back from the darkest parts of depression, anxiety, PTSD, and chronic addiction,” Texas Rep. Cody Harris added in the release. “I am excited to walk alongside UTHealth Houston and UTMB as these stellar institutions lead the nation in a first-of-its-kind clinical trial in the U.S.”

Recently, the University of Houston also received a $2.6 million gift from the estate of Dr. William A. Gibson to support and expand its opioid addiction research, which includes the development of a fentanyl vaccine that could block the drug's ability to enter the brain. Read more here.

Tesla no longer world's biggest EV maker as sales fall for second year

Tesla Talk

Tesla lost its crown as the world’s bestselling electric vehicle maker as a customer revolt over Elon Musk’s right-wing politics, expiring U.S. tax breaks for buyers and stiff overseas competition pushed sales down for a second year in a row.

Tesla said that it delivered 1.64 million vehicles in 2025, down 9% from a year earlier.

Chinese rival BYD, which sold 2.26 million vehicles last year, is now the biggest EV maker.

It's a stunning reversal for a car company whose rise once seemed unstoppable as it overtook traditional automakers with far more resources and helped make Musk the world's richest man. The sales drop came despite President Donald Trump's marketing effort early last year when he called a press conference to praise Musk as a “patriot” in front of Teslas lined up on the White House driveway, then announced he would be buying one, bucking presidential precedent to not endorse private company products.

For the fourth quarter, Tesla sales totaled 418,227, falling short of even the much reduced 440,000 target that analysts recently polled by FactSet had expected. Sales were hit hard by the expiration of a $7,500 tax credit for electric vehicle purchases that was phased out by the Trump administration at the end of September.

Tesla stock fell 2.6% to $438.07 on Friday.

Even with multiple issues buffeting the company, investors are betting that Tesla CEO Musk can deliver on his ambitions to make Tesla a leader in robotaxi services and get consumers to embrace humanoid robots that can perform basic tasks in homes and offices. Reflecting that optimism, the stock finished 2025 with a gain of approximately 11%.

The latest quarter was the first with sales of stripped-down versions of the Model Y and Model 3 that Musk unveiled in early October as part of an effort to revive sales. The new Model Y costs just under $40,000 while customers can buy the cheaper Model 3 for under $37,000. Those versions are expected to help Tesla compete with Chinese models in Europe and Asia.

For fourth-quarter earnings coming out in late January, analysts are expecting the company to post a 3% drop in sales and a nearly 40% drop in earnings per share, according to FactSet. Analysts expect the downward trend in sales and profits to eventually reverse itself as 2026 rolls along.

Musk said earlier last year that a “major rebound” in sales was underway, but investors were unruffled when that didn't pan out, choosing instead to focus on Musk's pivot to different parts of business. He has has been saying the future of the company lies with its driverless robotaxis service, its energy storage business and building robots for the home and factory — and much less with car sales.

Tesla started rolling out its robotaxi service in Austin in June, first with safety monitors in the cars to take over in case of trouble, then testing without them. The company hopes to roll out the service in several cities this year.

To do that successfully, it needs to take on rival Waymo, which has been operating autonomous taxis for years and has far more customers. It also will also have to contend with regulatory challenges. The company is under several federal safety investigations and other probes. In California, Tesla is at risk of temporarily losing its license to sell cars in the state after a judge there ruled it had misled customers about their safety.

“Regulatory is going to be a big issue,” said Wedbush Securities analyst Dan Ives, a well-known bull on the stock. “We're dealing with people's lives.”

Still, Ives said he expects Tesla's autonomous offerings will soon overcome any setbacks.

Musk has said he hopes software updates to his cars will enable hundreds of thousands of Tesla vehicles to operate autonomously with zero human intervention by the end of this year. The company is also planning to begin production of its AI-powered Cybercab with no steering wheel or pedals in 2026.

To keep Musk focused on the company, Tesla’s directors awarded Musk a potentially enormous new pay package that shareholders backed at the annual meeting in November.

Musk scored another huge windfall two weeks ago when the Delaware Supreme Court reversed a decision that deprived him of a $55 billion pay package that Tesla doled out in 2018.

Musk could become the world's first trillionaire later this year when he sells shares of his rocket company SpaceX to the public for the first time in what analysts expect would be a blockbuster initial public offering.
