Major catalysts include the FIFA World Cup in North America, where Erling Haaland, Lamine Yamal, and Kylian Mbappé could generate global interest through standout performances, and the Winter Olympics, potentially elevating figure skater Alysa Liu.

Late-season injuries, viral moments, or unexpected breakthroughs remain realistic variables that could shift the crowded field before year-end resolution.
