Football is back, baseball is deep into its stretch run, and Buffalo just opened a building that cost more than some countries’ GDP. But don’t worry, the taxpayers gave up a bunch of stuff to help fund it. Underneath all of it, there’s a quieter story: artificial intelligence has stopped being a press-release word in sports and started showing up in places fans actually notice.
Here are three worth paying attention to right now.

1. Baseball’s robot umps are real, and the numbers are wild
The biggest AI story in sports this year isn’t a chatbot. It’s MLB’s Automated Ball-Strike challenge system, which went live league-wide for the 2026 season. Each team gets two challenges per game. The pitcher, catcher, or batter taps their helmet or cap, Hawk-Eye tracking spits out a verdict on the videoboard in a couple of seconds, and everybody moves on. Get it right, you keep the challenge. Get it wrong, you lose it.
What’s remarkable is how often the humans were wrong. Through early August, more than 7,000 calls had been challenged and roughly 53% were overturned. That’s a coin flip. It means players are pretty good at knowing when they got squeezed — and that the strike zone was always a lot blurrier than the broadcast box suggested.
The best challengers aren’t the hitters. It’s the catchers, who see every pitch from six feet away and have the best feel for the zone. Salvador Perez has been near the top all season. Batters, meanwhile, hover well under 50% — turns out standing in the box against a 98-mph slider is a bad place to judge a two-inch miss. (Baseball Savant’s ABS dashboard has the full leaderboard if you want to fall down that hole.)
The genius of the design is that it didn’t replace the umpire. It just gave players a way to fix the worst calls without turning every at-bat into a replay review.
2. The NFL is using AI on the outside of the stadium
The most interesting NFL AI story this season isn’t about the game at all. PerVista AI, a Maryland company, is running weapons-detection systems at Northwest Stadium in Landover and Mercedes-Benz Stadium in Atlanta. The focus is the parking lots and walkways — the tailgate zone, where there are no magnetometers and everyone’s guard is down.
The system compares camera frames against a dataset of firearms. When it flags something, a human in a 24/7 operations center verifies it before anything happens. CEO Vennard Wright makes a point of the privacy design: the cameras aren’t matching faces, and nothing is retained unless there’s an actual incident. “We’re not looking for people,” he told WTOP. “We’re looking for weapons.”
Elsewhere, the league leaned on AI to build the schedule itself. The NFL works with Recentive Analytics to project viewership for essentially any game in any time slot, then tests schedule permutations against each other. With a record nine international games in 2026 — London, Melbourne, Rio, Paris, Madrid, Munich, Mexico City — the 272-game puzzle got genuinely hard to solve by hand.
3. Buffalo’s new stadium is smart, if not exactly intelligent
New Highmark Stadium opened its doors for the first time on August 8 with the Bills’ Blue & Red practice. The $2.1 billion, 60,108-seat venue is worth a mention here with an honest caveat: most of what’s impressive is automation and sensors, not AI.
Still, it’s a genuinely modern building. There’s an 18,000-square-foot standalone technology building outside the stadium — a first in the NFL — housing the network infrastructure. The natural grass field has sub-air, hydronic heating, grow lights, and wirelessly controlled irrigation, so it can survive a Buffalo December. Add the largest roof snowmelt system in the league, 65% covered seating, and infrared heaters under the decks.
Translation: the field manages its own climate. In Orchard Park, that might be the most useful technology of all.
