A technology built at MIT decided the 2022 World Cup. Semi-automated offside technology (SAOT), developed by the MIT Sports Lab in collaboration with FIFA, determined that Argentine forward Lautaro Martinez was onside during Lionel Messi's 78th-minute goal in extra time, preserving a 3-2 lead. The system analyzed skeletal tracking data in real time and produced a single image that overruled the raised flag. Argentina won the championship. Without SAOT, that call goes differently.
The MIT Sports Lab, founded in 2015 by mechanical engineering professor Anette Hosoi and entrepreneur Christina Chase, is not an academic side project. It has active partnerships with FIFA, the NBA, the NFL, and Adidas. Its work touches officiating systems, player analytics, and equipment design. The lab exists because leagues and brands are drowning in tracking data they cannot process internally. MIT provides the math and engineering to extract something useful from it.
The full article is worth reading for what it reveals about the technical obstacles behind SAOT, including early skeletal data that placed players underground or floating above the pitch in anatomically impossible positions. Those problems had to be solved before any referee could trust the output. The lab's decade of accumulated work across multiple sports is the actual story here, and the World Cup final is just the most visible proof that it matters.
