The records that could be broken in the T20 World Cup are

Most boundaries record:
Mahela Jayawardene of Sri Lanka has hit the most fours in the T20 World Cup with 111 boundaries. Virat Kohli, with 103 fours, is close behind and could potentially break this record. Rohit Sharma, with 91 fours, and David Warner, with 86, are also contenders.

Fastest century record:
Chris Gayle holds the record for the fastest century in T20 World Cup history, having scored centuries in 47 and 50 balls. However, Jan Nicol Loftie of Nepal made the fastest century this year in just 33 balls. With 20 teams participating, including some weaker teams, a strong batsman could potentially break Gayle’s record against them.

Most catches as a fielder record:
AB de Villiers of South Africa tops the list with 23 catches in the T20 World Cup. David Warner, with 21 catches, could set a new record with just a few more. Rohit Sharma and Glenn Maxwell, both with 16 catches, are also in the race.

Record of winning all ICC trophies:
Last year, Pat Cummins led Australia to win the ICC Test Championship and the ODI World Cup. If Australia wins the T20 World Cup this time, they will be the first team to hold all ICC trophies simultaneously.

Record for most runs in a single edition:
With an increased number of teams, the number of matches is also increasing. A team will have to play a total of 9 matches to reach the final. Therefore, the record for most runs in a single edition of the T20 World Cup could also be broken. Currently, Virat Kohli tops the list with 316 runs in 6 matches during the 2014 T20 World Cup. This record could be broken by him or someone else this year.
