It's no secret that Austin and San Antonio are becoming some of the biggest cities in Texas, and that together, they just might rival the likes of Houston and Dallas-Fort Worth one day.

A new documentary called San Antonio-Austin: The Emerging Mega-Metro takes a deep dive into the booming 80-mile region between the Central Texas cities

Produced by KLRN, San Antonio's local PBS station, the program centers on the region's growth and the challenges that arise with such rapid expansion, such as water scarcity, environmental impacts, and increasingly common transportation and traffic woes.

They're issues that Houston residents know well, as the city's population continues to explode at a staggering rate.

"We know the area between San Antonio and Austin is growing at a tremendously rapid pace, but what is really happening is the development of a mega-metro that will be one of the biggest economic powerhouses in the world," says Shari St. Clair, the documentary's executive producer, in a release.

“We delve into the questions that need to be asked right now — how do we retain quality of life as we grow? How do we build a sustainable workforce?" St. Clair continues. "And, can San Antonio and Austin truly join forces and work together to make the most of this incredible opportunity?"

The hour-long documentary is hosted by former San Antonio mayor Henry Cisneros, who also authored The Texas Triangle: An Emerging Power in the Global Economy. The special highlights several prominent Central Texas leaders, including interviews with Austin Mayor Kirk Watson, San Antonio Mayor Ron Nirenburg, U.S. Congressman Greg Casar, and more.

As Texas is also a state of committed sports fans, the idea of a mega-metro between Austin and San Antonio is additionally explored through a sports lens. The documentary interviewed legends like Nolan Ryan, Sean Elliot, and Spurs Chairman Peter J. Holt.

Houston-Dallas high-speed bullet train gets back on the rails thanks to potential Amtrak partnership

speeding back

In the latest chapter in the saga of the high-speed bullet train between Houston and Dallas, Amtrak is now involved.

According to a press release, Texas Central Partners and Amtrak are exploring a partnership to work together on the proposed Dallas-Houston high-speed rail project that's been under consideration for more than a decade.

Amtrak has cooperated with Texas Central on various initiatives since 2016 and the two entities are now evaluating a potential partnership to determine the line's viability.

“If we are going to add more high-speed rail to this country, the Dallas to Houston Corridor is a compelling proposition and offers great potential,” says Amtrak senior VP of High-Speed Rail Development Programs Andy Byford. “We believe many of the country's biggest and fastest-growing metropolitan areas, like Houston and Dallas, deserve more high quality high-speed, intercity rail service, and we are proud to bring our experience to evaluate this potential project and explore opportunities with Texas Central so the state can meet its full transportation needs.”

The route being proposed would span approximately 240 miles, going at 250 mph, resulting in a trip that would take less than 90 minutes between the two cities.

Texas Central has been working towards getting a train rolling since 2013, including lining up a potential builder in 2021. But the project has had pushback from Texas politicians and landowners along the route; a lawsuit against the project was filed by six rural counties in 2021, and the Texas Legislature passed a law prohibiting the state from spending any funds on the project.

Facing a seeming dead end, Texas Central CEO Carlos Aguilar and its board members resigned in June 2022; Michael Bui, a consultant, has been serving as CEO since then.

Texas Central and Amtrak have submitted applications to several federal programs in connection with further study and design work, including the Consolidated Rail Infrastructure Safety and Improvements (CRISI) grant program, the Corridor Identification and Development program, and the Federal-State Partnership for Intercity Passenger Rail (FSP-National) grant program.

Amtrak previously entered into an agreement with Texas Central to provide through-ticketing using the Amtrak reservation system and other support services for the planned high-speed rail line.

"This high-speed train, using advanced, proven Shinkansen technology, has the opportunity to revolutionize rail travel in the southern U.S., and we believe Amtrak could be the perfect partner to help us achieve that,” says Bui in a statement.

Despite its detractors, the project is forecast to provide social, environmental, employment and economic benefits including reducing greenhouse gas emissions by more than 100,000 tons per year, saving 65 million gallons of fuel and removing 12,500 cars per day from I-45.

The release from Amtrak has statements from both Dallas Mayor Eric L. Johnson and Houston Mayor Sylvester Turner, who calls the collaboration between Texas Central and Amtrak "an important milestone for the City of Houston and this project."

Byford joined Amtrak in April 2023 to begin developing a team focused on high-speed opportunities throughout the U.S. In his newly created role, he will develop and lead the execution of Amtrak’s long-term strategy for high-speed rail throughout the country, including the extension of the Crescent from Mississippi through Louisiana and Texas; Kansas DOT’s Heartland Flyer Extension Corridor Identification and Development (Corridor ID) connecting Wichita to Oklahoma and Texas, and TxDOT’s applications for the Texas Triangle (Houston — Dallas – Fort Worth – San Antonio) routes.

Houston startup funding surpasses $1B in 2025 despite national slowdown

by the numbers

Houston-area startups raised more than $1 billion in venture capital during the first half of 2025 — almost double the haul for the first half of last year.

According to the new PitchBook-NCVA Venture Monitor, Houston-area startups raised $417.2 million in the second quarter of this year, compared with $281 million during the same period last year. In the first quarter of 2025, local startups collected $607.5 million in venture capital, compared with $281 million during the same period a year earlier.

Based on those figures, Houston-area startups picked up slightly over $1 billion in VC during the first half of this year, compared with $535 million in the first half of 2024.

Nationally, startups gained almost $70 billion in VC in the second quarter, down 25 percent from the same period a year ago, the PitchBook-NCVA Venture Monitor says.

Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook, explained that “the VC landscape continues to navigate a fragile recovery” and is constrained by economic uncertainty.

However, startups in certain sectors are poised to attract a great deal of attention and venture capital over the next several years, according to the report.

“Companies operating in AI, national security, defense tech, fintech, and crypto — sectors aligned with the administration’s priorities — are attracting disproportionately more investor interest, and this trend will likely continue throughout President Donald Trump’s term,” the report says.

The AI sector accounted for 64 percent of VC deal value in the first half of 2025, according to the report.
