The 2026 T20 World Cup features 20 participating teams: India, Sri Lanka, Afghanistan, Australia, Bangladesh, England, South Africa, United States, West Indies, Ireland, New Zealand, Pakistan, Canada, Italy, Netherlands, Namibia, Zimbabwe, Nepal, Oman, and the UAE.
The tournament format mirrors the previous edition: 20 teams are divided into four groups of five, with round-robin play in each group. The top two teams from each group advance to the Super 8, forming two groups of four based on pre-tournament seedings for a second round-robin. The leading teams from the Super 8 then move to the knockout stage, culminating in the championship match.
