Eliminated for the first time from consecutive seasons
Until 2019, CSK made it to the playoffs in every season that they had been a part of. In 2020, they were eliminated in the league stage for the first time ever.
Since then, CSK followed a bizzare alternating pattern where they would be eliminated in the group stages in even years (2020, '22, '24) and become champions in odd years (2021, '23). In 2025, the pattern did not hold as CSK have been eliminated in the group stages in two consecutive IPL seasons for the first time ever.
