The tournament features 32 teams from around the world, competing for a $1 billion prize pool across 12 venues, making it the largest and most ambitious club soccer event in history. The tournament's format has changed from annual winter contests to a quadrennial event, drawing criticism from players and unions over the demanding fixture schedule, which exacerbates concerns about player health and safety. Notably, FIFPRO has launched a legal challenge against FIFA, alleging abuse of dominance and risking player well-being due to the increased number of matches.

The opening match saw Lionel Messi's Inter Miami draw 0-0 with Al Ahly, with goalkeeper Oscar Ustari earning Man of the Match honors. The tournament includes top clubs like Manchester City, Bayern Munich, Real Madrid, and Paris Saint-Germain, with group stages featuring notable teams from Europe, South America, Africa, and Asia. Prominent players such as Messi, Erling Haaland, Kylian Mbappe, and Harry Kane are participating, with some teams like Monterrey and Urawa Red Diamonds confident about their chances. The event also highlights ongoing political and social issues, with debates over security and immigration policies impacting the tournament's atmosphere.
