The 2026 World Cup has introduced a groundbreaking officiating system that uses artificial intelligence to call offsides with unprecedented accuracy. FIFA's new Semi-Automated Offside Technology (SAOT) reduces the margin of error from 50 centimeters to just 10, leveraging 29 tracking cameras, a sensor inside the match ball, and AI-generated 3D player avatars.
When an offside violation occurs, the referee receives an instant audio alert in their earpiece, eliminating lengthy VAR reviews. Before the tournament, each player underwent a one-second digital body scan to create precise 3D models that capture exact body positions, including limbs that cameras might miss.
The system blends machine precision with human judgment: AI handles the geometric calculations of offside positioning, while referees make decisions on edge cases requiring context. This marks a pivotal moment where algorithms manage high-stakes decisions under global scrutiny.
Tennis is expected to adopt similar technology next, followed by basketball and other sports, signaling a future where AI plays a central role in officiating.
