The expanded 48-team tournament is not just a sporting operation. It is a continental security test.
The 2026 FIFA World Cup will be the largest tournament in football history: 48 teams, 104 matches, three host countries and an attention footprint stretching across the planet. That scale creates joy. It also creates vulnerability.
A recent CSIS brief described the tournament as the largest sporting event ever held and a potential magnet for foreign terrorist groups and domestic extremists. Major sporting events have long appealed to violent actors because they combine crowds, symbolism, media attention and operational complexity.
The Global Terrorism Index 2026 provides the wider threat landscape. It found that Islamic State and its affiliates remained the deadliest terrorist organisation in 2025, though active in fewer countries, while IS, JNIM, TTP and al-Shabaab together accounted for 3,869 deaths — about 70% of all terrorism fatalities.
This matters for the World Cup because security risk is no longer a single-profile problem. It is not only a question of one international group attacking one iconic venue. Authorities must consider lone actors, online radicalisation, soft targets, transport networks, cyber-enabled disruption, protest spillovers and politically charged immigration enforcement around stadiums.
There are also geopolitical overlays. Iran’s football federation has alleged ticket-allocation problems shortly before the tournament, while visa uncertainty and regional tensions have already affected preparations. Somalia’s Omar Abdulkadir Artan was reportedly denied entry to the United States, preventing a potential historic officiating milestone.
Security officials now face a paradox: the safer the event feels, the less visible their success becomes. But over-securitisation carries its own risk — turning football spaces into political checkpoints.

The Next Signal
The opening week will show whether security agencies can maintain both safety and civility. In a mega-event, crowd confidence is itself a security asset. Lose that, and every queue begins to feel like a fault line.
