In the 2026 World Cup, every match features an Adidas‑manufactured Trionda, a fully connected ball that streams data in real time. The ball must be charged before every game, with a 0% battery taking 2½ hours to reach full power and lasting up to six hours on the field.

The Trionda’s embedded chip is now positioned on the sidewall of one panel, a shift from the previous center‑bladder design. Engineers ran over 300 lab tests to confirm that the chip’s weight does not alter flight, spin or balance. This tweak eliminated the erratic behavior that plagued the 2010 Jabulani.

During the Sweden‑Tunisia match, sensor data overturned a ref‑called offside, allowing a goal that had been disallowed. The Qatar ball could not provide that precision. The new technology also feeds into automated offside decisions, giving referees a clearer, faster verdict.

Teams now use non‑connected balls for training and the Trionda for games, distinguished by colored valves. The system’s fail‑safes and real‑time charge monitoring ensure no ball dies mid‑match, keeping the tournament’s flow uninterrupted.
