What new rules and technology debut at the 2026 World Cup?
The 2026 World Cup introduces faster semi-automated offside (flagging players just 10 cm offside), AI tracking and 3D replays, ball-tracking to judge if the ball crossed a line, referee body cameras, a 10-second limit to complete substitutions, and an 8-second limit for goalkeepers to release the ball.
- 1Semi-automated offside now alerts the assistant referee when a player is even ~10 cm offside, down from a 50 cm margin[1]
- 2FIFA built AI 3D avatars of all 1,248 players for clearer offside replays[1]
- 3New ball-tracking can show whether the ball fully crossed a line, like goal-line technology[1]
- 4Other 2026 tweaks: referee body cameras, a 10-second substitution limit, and an 8-second goalkeeper rule[2]
2026 is the most tech-heavy World Cup yet, with automation speeding up calls.
What's new with offside?
Faster semi-automated offside: AI tracks dozens of points on every player many times a second, so the flag goes up almost immediately. It now flags a player even ~10 cm offside, down from the old ~50 cm margin — but the referee still makes the final call.
What other technology debuts?
FIFA built AI 3D avatars of all 1,248 players for cleaner offside replays, and added ball-tracking that can show whether the ball fully crossed a line.
What rule tweaks are there?
Referee body cameras for broadcast angles, a 10-second limit to complete a substitution, and an 8-second limit for goalkeepers to release the ball — or the opponent gets a corner.
Think of it as soccer's version of the NFL adding chips in the ball and faster replay review — automation to speed up calls and cut dead time, while keeping a human official with the final say.
Key Takeaways
- New tech includes faster semi-automated offside, ball-tracking on goal-line calls, and referee body cameras.
