Sports betting isn't legal in Texas, but one of our in-state reporters used the prediction market Kalshi to put money on the outcome of the Super Bowl.

Why it matters: Kalshi, which is regulated by the federal Commodity Futures Trading Commission (CFTC), is not considered a sports betting app.

• Instead, the app allows users to buy and trade contracts on the outcomes of various events. Even though some states prohibit sports gambling, Kalshi has opened up sports event trading contracts in all 50 states.

The latest: Our reporter onboarded with Kalshi using an Axios email and a debit card. She uploaded the minimum amount ($10) via debit card and then put it all on one of the teams.

• After fees were deducted, she was able to purchase a contract with her remaining $9.18. She'll get $17 if they win.
• As it ran a check on her, Kalshi returned matching data that made clear it was aware she's a Texas resident.

The big picture: The matchup this weekend between the Philadelphia Eagles and the Kansas City Chiefs could break records in legal betting in the U.S.

Context: There's been a steady drumbeat to legalize sports betting across the country since New Jersey did it in 2018.

• Texas is a major holdout.

What they're saying: Kalshi declined to comment to Axios. The CFTC and the Texas State Securities Board did not reply to Axios' requests for comment.

• Gov. Greg Abbott told the Express-News this week he's open to legalizing sports betting. But he did not name it as a priority in his State of the State speech over the weekend — and Lt. Gov. Dan Patrick has shot down its prospects in the Texas Senate.

Between the lines: Some state lawmakers have argued that many Texans are already betting on sports illegally using websites and apps.

San Antonio will have a hand in the effort to resurrect high speed air travel, a quest that recently hit a new milestone.

Why it matters: Boom Supersonic is seeking to reestablish American leadership in aviation amid a broader race for supremacy in AI, space exploration and other technologies, its CEO Blake Scholl tells Axios.

• It's the first independent company to design, build and fly a supersonic aircraft.

The latest: The XB-1 prototype of a passenger jet broke the sound barrier for the first time last week above the Mojave Desert in California.

• The prototype is one-third the size of the Overture jet that Boom plans to use for passenger flights.

Zoom in: StandardAero in San Antonio will assemble and produce the bespoke engines, called Symphony, for the Overture jet.

• The plane could carry up to 80 passengers at the speed of sound, about twice the speed of today's airliners.
• That could mean flying from Washington, D.C., to Paris in four hours, or from San Francisco to Tokyo in six hours.
• It's designed to fly on 100% sustainable aviation fuel (SAF) made from feedstocks like household solid waste, algae or used cooking oil. That means dramatically lower carbon emissions than traditional jet fuel.
• SAFs are in short supply, however, meaning until production increases, much of the plane's environmental benefits won't be immediately realized.

What's next: Boom has 130 orders and "pre-orders" from American Airlines, United Airlines and Japan Airlines — a five-year pipeline of production, Scholl says.

• Boom expects to begin commercial service by 2029.
