Texas earns 22nd 'best state for business' title as GDP hits $2.9T

booming economy

The Texas business sector recently received a double dose of good news.

For the 22nd consecutive year, Chief Executive magazine named Texas the best state for business. In tandem with that achievement, preliminary new estimates from the U.S. Bureau of Economic Analysis show the size of Texas’ economy jumped to $2.9 trillion in 2025, up by a nation-leading growth rate of 2.5 percent compared with the previous year.

Speaking about the Chief Executive honor, Gov. Greg Abbott says Texas benefits from pro-growth policies, a strong workforce, strategic investments in education, training for high-demand skills and the presence of critical infrastructure.

“Texas is where businesses innovate and where opportunity abounds. … We will continue to move at the speed of business as we build a more prosperous Texas for generations to come,” the governor says.

An annual Chief Executive survey of CEOs, presidents and business owners determines which state is the best for business. Texas has landed at No. 1 every year since Chief Executive launched the ranking.

“Truly, this is an incredible run that Texas has going,” says Christopher Chalk, publisher of Chief Executive. “CEOs are a tough group to please, and yet year after year Texas continues to earn the top spot—no small feat.”

It’s also no small feat for a state to notch annual gains in its gross domestic product (GDP), a measurement of economic power based on the value of goods and services produced each year.

With an estimated GDP of $2.9 trillion last year, Texas maintains its position as the eighth-largest global economy compared with the nations of the world, based on preliminary estimates from the International Monetary Fund.

In reference to Texas’ GDP growth, Abbott says the Lone Star State is “the premier destination for job creators from across the country and world. We will keep attracting world-class investment, create jobs, and expand opportunity for Texans for generations to come.”

UH med school granted $2M gift to offer student scholarships

scholarship gift

A new scholarship endowment aims to support students in the University of Houston’s recently established medical school.

The University of Houston’s Tilman J. Fertitta Family College of Medicine received a planned estate gift commitment estimated at $2.1 million to establish the Bob Diehl and Teresa Evans Diehl Scholarship Endowment. The scholarship will assist full-time medical students who demonstrate financial need and meet academic standards.

“Endowed scholarships like this do more than ease the burden of tuition—they empower our students to focus on learning, leadership and compassionate care,” Jonathan McCullers, UH vice president of health affairs and dean of the Fertitta College of Medicine, said in a news release. “We are deeply grateful to the Diehls for their vision and commitment to expanding access to health care through education.”

The endowment aims to provide annual scholarship support for students enrolled in the Fertitta College of Medicine. The gift also aligns with the university's fundraising initiative focused on expanding opportunities for students, known as Can’t Stop Houston: The Centennial Campaign, which works to expand research ahead of UH’s 100th anniversary next year.

The Diehls are both graduates from UH, and Bob Diehl spent 38 years working at UPS.

“It brings me happiness to know that my endowment will make a difference in young people's lives and in the communities that will need those future doctors,” he said in the release.

The Fertitta College of Medicine welcomed its inaugural class of 30 students in 2020 and expects classes to grow to 120 students in the coming years, according to UH. The university believes scholarship opportunities will be crucial for students to pursue medical education despite financial challenges.

“The Diehl family’s generosity will open doors for talented future physicians who are called to serve our communities but may otherwise face financial barriers to pursuing a medical education,” McCullers added.
