Kaśnikowski has a career high ATP singles ranking of world No. 245 achieved on 15 April 2024. He also has a career high ATP doubles ranking of No. 688 achieved on 8 May 2023.
Kaśnikowski represents Poland at the Davis Cup, where he has a W/L record of 2–1.
In October, he reached his first Challenger final in Ortisei, Italy and moved into a new career high in the top 290 in the rankings, that he first reached on 3 July 2023.
He won his first Challenger title at the 2024 Oeiras Indoors, saving six match points in the opening round against Adrian Andreev, becoming the second-youngest Polish champion in history to win a title. Only a 19-year-old Jerzy Janowicz was younger when he won his title in St. Remy, France in 2010.
