The official World Cup ball now has something in common with a phone, a smartwatch, and nearly every other piece of modern tech: it needs to be charged.
Adidas’ Trionda, the match ball being used at the 2026 World Cup, is more than just a four-panel soccer ball with a red, green, and blue design meant to nod to the United States, Mexico, and Canada. It is also a connected device. Inside the ball is a small motion sensor that tracks its movement hundreds of times per second and sends data to the VAR room in real time.

That may sound like a strange detail for a sport still built around feet, grass, bodies, and instinct. But during Sweden’s win over Tunisia, the ball already proved its worth, as the internal sensor helped decide whether a record-setting goal should count.
In the 84th minute of Sweden’s win over Tunisia on Sunday, June 14, midfielder Mattias Svanberg came off the bench and scored with his first touch, just 12 seconds after entering the match. The goal would make him the fastest substitute ever to score at a World Cup, but it was initially ruled out for offside.

The review came down to one hard-to-see detail: whether Sweden forward Alexander Isak had made a slight touch on the ball before it reached Svanberg. If he had not touched it, Svanberg would remain offside. If he had, the phase of play would reset, and the goal could count.
According to an ESPN VAR review of the incident, officials used Adidas’ connected ball tracking technology to determine that Isak had indeed made contact. The touch was so slight that it was difficult, if not impossible, to judge clearly with the naked eye…but the sensor registered it. VAR overturned the original offside decision. Svanberg’s record-setting goal stood.
Connected ball technology is not new to the World Cup. Adidas first used a sensor-equipped match ball at the 2022 World Cup in Qatar. For 2026, the technology has been updated, though, with a side-mounted 500Hz chip inside one of Trionda’s four panels, allowing the ball to send real-time, three-dimensional movement and touch data to VAR.
In a World Cup increasingly shaped by technology, the smallest touch can now be enough to make history.
