The richest billionaires in America have a collective worth of $8 trillion in 2026, a staggering $1.4 trillion increase since last year, says Forbes. American billionaires are so wealthy that it now takes an unprecedented $4.4 billion net worth to be considered one of the richest people in the country. And one local billionaire has regained the title as Houston's wealthiest resident.

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. In all, 43 billionaires across Texas made it on the 2026 list, and 10 are based in Houston. Seven of them have ties to the energy industry.

Oil tycoon Jeffery Hildebrand, 67, now reigns as the No. 1 richest Houstonian, the 9th richest Texan, and the 88th richest person in America for 2026. Hildebrand's net worth has surged $4.7 billion since last year, bringing his current net worth to $14.7 billion. He cofounded Hilcorp, one of the largest privately owned oil and natural gas producers in the U.S., in 1990 and served as its CEO until 2018. He still serves as the chairman of the company.

Kinder Morgan chairman Richard Kinder is the No. 2 richest in Houston. Kinder, 81, was dubbed Houston's richest billionaire in the 2025 Forbes 400 list. His net worth has increased from $11.1 billion to $12.9 billion in just one year. He is the 11th richest Texan and the 100th richest person in America.

Houston pipeline heir Randa Duncan Williams ranks 124th on the list with an estimated net worth of $11.7 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 128th nationally. Each has an estimated net worth of $11.6 billion. Scott Duncan ties for No. 137 with an $11.3 billion estimated net worth.

Energy exploration chief executive George Bishop of GeoSothern Energy ranks No. 380 with an estimated net worth of $4.5 billion. Last year: $4.7 billion.

Here's how the rest of Houston's billionaires, outside of the energy industry, ranked on this year's list:

Toyota mega-dealer Dan Friedkin, 61, is the 102nd richest American with an estimated net worth of $12.9 billion, up from $9.7 billion last year. He most notably owns Gulf States Toyota, which sold $14.5 billion worth of Toyotas in 2025, per Forbes.
Hospitality honcho Tilman Fertitta, 69, has a net worth of $12.3 billion and is the 110th richest American. Fertitta owns hospitality corporation Fertitta Entertainment and the NBA team Houston Rockets. He most recently purchased the WNBA's Connecticut Sun and plans to relocate them to Houston under the Houston Comets name in 2027. He also keeps himself busy as President Trump's ambassador to Italy.
Texans owner and CEO Cal McNair, 64, ranks as the 218th richest person in America with an estimated net worth of $7.7 billion.

Texas billionaire Elon Musk, Houston energy execs named richest in America by Forbes

report

SpaceX and Tesla co-founder Elon Musk has topped Forbes' list as the wealthiest person in America for the third time. Musk is one of seven Austin billionaires who have made the new Forbes 400, a list of the 400 richest people in the United States for 2024.

Forbes estimates Musk's net worth in 2024 as $244 billion, which is $7 billion less than his estimated net worth last year. Musk, 53, is the cofounder of seven companies, including SpaceX, xAI, The Boring Company, among others. He serves as the CEO of Tesla, which is headquartered in Austin.

In 2022, Musk famously acquired Twitter in a $44 billion deal.

"Forbes estimates that the social media company, which he renamed X, is worth nearly 70 percent less as of August 2024.," Forbes wrote in Musk's profile.

Most recently, court filings revealed Musk shifted his plans to relocate X's headquarters from San Francisco to Bastrop, a city 30 miles southeast of Austin. He originally stated he would be moving the company's headquarters to Austin in July 2024, after California Governor Gavin Newsom signed a new law that barred school districts from requiring staff to notify parents of their child’s gender identification change.

A dozen of Houston's illustrious billionaires have also made the cut on the list. Houston hospitality king and Rockets owner Tilman Fertitta is the 12th richest Texan and the 99th richest person in the United States, according to Forbes' list, released October 1.

Forbes estimates Fertitta's net worth in 2024 as $10.1 billion, which has steadily climbed from his 2023 net worth of $8.1 billion. Fertitta, 67, purchased the Houston Rockets in October 2017 for $2.2 billion. The billionaire also owns Texas-based hospitality and entertainment corporation Landry's. In 2019, Fertitta embarked on a new venture as an author.

"Fertitta released his first book titled Shut Up And Listen! in September [2019], detailing his experiences in the dining and entertainment industries," Forbes wrote in Fertitta's profile.

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

According to the report, America's elite class is now worth $5.4 trillion collectively, which is a $1 trillion jump since 2023.

“The Forbes 400 is richer than ever, and it’s harder than ever to be one of the 400 richest people in America," said Forbes senior editor Chase Peterson-Withorn in a press release.

In all, 43 Texas billionaires made the list. Newcomers include Houston-based Westlake Corporation co-owners Albert Chao, James Chao, and their respective families. According to their Forbes profiles, the Chaos own nearly 25 percent of Westlake Corporation, which produces low-density polyethylene that is used for food packaging and other products.

"His father, T.T. Chao, moved the family from Taiwan to the U.S. and founded Westlake in 1986," Albert Chao's profile says. "Albert and brother James Chao are credited with helping launch the company. Albert was CEO from 2004 to July 2024, when he became executive chairman. James was chairman from 2004 to July 2024, when he became senior chairman."

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

Oil and gas chairman Richard Kinder ranks No. 112 nationally with an estimated worth of $9.3 billion.
Houston pipeline heir Randa Duncan Williams ties for No. 126 with an estimated net worth of $8.6 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 130th nationally. Each has an estimated net worth of $8.5 billion. Scott Duncan ranks No. 137 with an $8.3 billion estimated net worth.
Toyota mega-dealer Dan Friedkin and Houston oil tycoon Jeffery Hildebrand tie for 156th nationally with an estimated net worth of $7.6 billion.
Houston Texans owner Janice McNair ties for No. 210 nationally with an estimated net worth of $6.2 billion.
Energy exploration chief exec George Bishop of The Woodlands ranks No. 266 with an estimated net worth of $5 billion.

Missing from the 2024 list is local hedge fund honcho John Arnold, who ranked No. 345 nationally in 2023 but now ranks No. 991 in 2024 with an estimated net worth of $3.3 billion. As of October 1, Forbes estimates Arnold's net worth at $2.9 billion.

Solid-state generator company secures $9M in financing, names CTO

fresh financing

ATS Energy has secured a $9 million investment to help commercialize its solid-state generator technology, a representative from the company tells Energy Capital.

The Colorado-based company is a member of Houston's Greentown Labs climatech community and was named the second most-promising startup in the Innovations for Traditional Energy, Electricity, & the Grid track during CERA Week's Energy Venture Day and Pitch Competition in March.

ATS's technology converts industrial waste heat into electricity via its proprietary thermoelectric cartridges, according to a news release. The cartridges convert the otherwise wasted thermal energy directly into usable electricity with no turbine, no moving parts and no emissions.

"We have spent years building a proven track record of breakthrough technology," Doug Hudson, CEO of ATS Energy, said in the release. "What has developed over the past year is that markets are moving toward ATS Energy, said in the release. We've moved well beyond early interest to commercial commitments, active proposals and a pipeline that continues to expand across multiple industrial sectors. That puts us in a tremendous position to meet the moment in delivering energy to industry. This investment responds to real commercial opportunity, and it positions ATS Energy to scale production, meet customer demand faster, and drive commercial deployments."

According to the release, ATS plans to complete and deploy its first commercial generator using the thermoelectric cartridges by mid-2027. The company shared that it plans to begin revenue-generating operations next year, as well.

ATS has also named Edward Ganja as its new CTO. Ganja previously served as a technology advisor for ATS and spent more than 30 years at Shell, most recently as vice president of catalyst and analytical technology in Houston, according to LinkedIn.

"Having worked closely with the team as a Technology Adviser, I am thrilled to step into the Chief Technology Officer role to lead our technology strategy and advanced materials scale-up," Ganja shared in a LinkedIn post. "ATS is tackling crucial energy challenges, and I look forward to working with our talented team, partners, and industry colleagues to accelerate our commercial development and technological footprint."

A representative from the company shares that ATS has three employees in Texas, including two in Houston. The company is targeting industrial facilities, including Gulf Coast refineries and petrochemical plants, for its production model, which will leverage established manufacturing capabilities to help quickly scale its commercial pipeline.

"We are scaling manufacturing with the discipline required for commercial-grade industrial deployment, moving beyond proof-of-concept to deliver mission-critical equipment," Terry Hill, COO of ATS, added in the release. "We've been building the supply chain, identifying the right manufacturing partners and putting the processes in place to move toward repeatable production. By leveraging contract manufacturing, we can focus our capital on the technology, the product and our customers rather than building factories. Just as importantly, we're working to reduce the time between installations so we can respond to the demand we're seeing in the market."

ATS won the prestigious Earthshot Prize in the Fix Our Climate category in 2024. The Earthshot Prize, founded by Prince William, awards £1 million to five energy startups each year over a decade.

Trump says he's ending restrictions on methane emissions from oil drilling

In the News

President Donald Trump said Tuesday that his administration is “terminating” a Biden-era rule that aimed to cut planet-warming emissions of methane from oil and gas drilling.

Trump said during a campaign rally in Texas that the change would save companies and consumers billions of dollars and unlock 210 million barrels of oil. That’s equivalent to about 10 days of U.S. petroleum consumption.

The move aims to encourage more domestic drilling as Trump faces criticism over high fuel prices amid the war in Iran.

Methane is responsible for about a third of planet-warming greenhouse gas emissions, scientists estimate.

Cuts in methane emissions have emerged in recent years as a global priority to slow the rate of climate change. Oil and gas operations are the largest industrial source of methane, which is the main component in natural gas and far more potent to the atmosphere than carbon dioxide in the short term.

The invisible gas leaks from equipment and is released into the atmosphere or burned off as a waste product by oil drillers.

Environmental Protection Agency Administrator Lee Zeldin previewed the changes last month, saying they would eliminate the agency’s “Super Emitter Program” that requires companies to investigate and repair major methane releases from oil and natural gas facilities. The agency would also set less restrictive standards for small oil and gas wells.

Trump said during Tuesday's rally in Lubbock for Texas Republican Senate candidate Ken Paxton that Biden's plan “crushed the small operators” with crippling regulations.

“I’m officially terminating Biden’s expensive and unnecessary methane regulations to save consumers and energy producers $45 billion in costs,” Trump said.

The loosening of the emissions rule comes as Trump and Republicans in Congress have been methodically dismantling climate policies enacted under former President Joe Biden. That's included the revocation of a scientific finding that was central to U.S. action on greenhouse gas emissions, lower fuel economy standards for vehicles and a move to repeal emission restrictions for coal and natural gas power plants.

Environmental groups said the latest rollback will let companies continue polluting the atmosphere with gas that could be captured and provide energy to millions of households.

Environmental Defense Fund President Fred Krupp said it gives a “free pass” to companies at the expense of American consumers.

“EPA should be fighting this waste, not making it easier,” he said.

Zeldin has said the methane rule would have cost $18 billion and was holding back the U.S. energy industry.

The Biden methane rule was announced by officials including former Vice President Kamala Harris during a 2023 U.N. climate conference in the United Arab Emirates.

Federal officials under Biden said it would prevent an estimated 58 million tons (52.6 million metric tonnes) of methane emissions by 2038 and reduce other pollutants that cause health problems.

By 2034, the rule was projected to yield $98 billion in benefits. That figure was derived by calculating the future “social costs” of greenhouse gas emissions on public health and the environment, an approach rejected by Trump's EPA.

While previous regulations focused only on new oil and gas wells in the U.S., the Biden rule regulated existing wells. Operators also would have needed to plug leaking methane from smaller wells that produce just 6% of the nation’s oil and gas while accounting for up to half of all methane emissions from oil and gas fields.

The final rule was published in 2024. The EPA last year imposed an 18-month delay to give companies time to meet new inspection requirements and other provisions.

The rule was crafted to be coordinated with a methane fee, approved in the 2022 climate law. The fee program would have levied a “waste emissions charge” of as much as $1,500 per metric ton of methane on energy producers that exceed a certain level of methane emissions.

The fee marked the first time the U.S. government directly imposed a fee, or tax, on greenhouse gas emissions. Congress repealed it weeks after Trump took office.

Officials also tried to rein in methane from oil and gas under former President Barack Obama, but that effort was scaled back during Trump's first term.

Houston energy company expands battery storage deal with Samsung

battery boost

Houston-based Alpha Omega Power, which develops, invests in and runs utility-scale battery energy storage systems, has signed a deal to add more storage capacity from a subsidiary of South Korean tech giant Samsung.

The latest deal adds 1 gigawatt-hour of storage capacity to Alpha Omega’s existing contract with Samsung SDI America, bringing total storage capacity to 1.5 gigawatts.

The Michigan-based Samsung subsidiary is manufacturing the systems’ cells and modules at a plant in Indiana, Alpha Omega said. Samsung SDI plans to deliver them by the end of this year.

“This second agreement strengthens our domestic supply chain supporting the next generation of energy infrastructure,” Paul Choi, CEO of Alpha Omega, said in a press release.

Houston-based Fengate Asset Management owns Alpha Omega. In 2023, they formed a partnership to build, acquire, and operate utility-scale battery energy storage projects in the U.S. Their 200-megawatt Vertus battery facility in Galveston County came online this month.

Alpha Omega plans to use the Samsung SDI systems to improve grid reliability and meet greater demand for power in markets served by the Electric Reliability Council of Texas (ERCOT) and the Salt Lake City-based Western Electricity Coordinating Council.

ERCOT covers 90 percent of power customers in Texas. The Western Interconnection grid covers all or part of 14 states, as well as parts of Canada and Mexico.

Samsung SDI is the only non-Chinese supplier of rigid-metal “prismatic” energy storage batteries in North America, according to Alpha Omega.

“With strong durability and fire safety compared with pouch-type batteries, its prismatic batteries have helped the company meet the stringent requirements of U.S. energy companies,” Alpha Omega said.

The Samsung Battery Box 1.7 equipment being purchased by Alpha Omega offers AI-powered algorithms and 25 years of continuous use, along with greater energy density than its predecessor. It also features the ability to directly inject fire-extinguishing agents on a module-by-module basis.
