Career

Early career Białecki started playing darts in 2015, at the age of 12. Białecki's first significant achievements were winning the Polish Junior Championship twice in 2017 and 2018. In 2019, he took part in international tournaments for the first time. At the beginning of 2020, he took part in PDC Q-School in order to obtain a PDC Tour Card, but was unsuccessful. He also took part in PDC Development Tour tournaments in Hildesheim, Germany, where he reached the Last 32 three times, and reached the semi-finals once, losing the match for the final with Ryan Meikle. In September 2020, he took part in the 2020 PDC World Youth Championship, advancing from group stage to the second round, where he again lost to Meikle, this time 0–6.

2021 In 2021, he took part in Q-School again, but was again unsuccessful. Good results on the Development Tour allowed Białecki to play in the 2021 UK Open. He was the first player in history to be born after the first edition of this tournament. In the first round, he faced Jim McEwan, achieved a nine-dart finish, and won the match 6–2. In the following matches of the tournament, he defeated Jitse Van der Wal (who also hit a nine-dart finish against him) and Derk Telnekes. He was eliminated in the fourth round, losing to Mensur Suljović 6–10.

In November, he also took part in the 2021 PDC World Youth Championship, but was eliminated in the group stage after going winless.

2022 Much like last year, Białecki qualified for the 2022 UK Open as a Development Tour qualifier. In this tournament, he achieved his best PDC result to date, beating Matt Campbell, Joe Murnan, Keegan Brown, Ritchie Edhouse, Ian White and Ryan Searle to reach the quarter-finals. He was eliminated by William O'Connor 9–10, despite having a match dart for a 150 checkout on double 15.

In April 2022, he took part in Denmark Open, his first senior WDF tournament and won the title, beating Ben Hazel, Andy Baetens, Dennis Nilsson, Shaun McDonald along the way before defeating Darren Johnson 6–1 in the final. This win guaranteed him qualification for the 2023 WDF World Darts Championship. In the same month, he took part in East Europe Qualifiers for the PDC European Tour and qualified for three tournaments.

In his European Tour debut at the 2022 Czech Darts Open, he lost 4–6 to Martijn Kleermaker in the first round. He was eliminated in first round of the 2022 Dutch Darts Championship, where he lost 1–6 to Jelle Klaasen.

Białecki took part in the 2022 PDC World Cup of Darts, representing Poland with Krzysztof Ratajski. In their first match, Poland struggled against Danny Baggish and Jules van Dongen of the US, but Poland won the match in a last leg decider. In the second round, Poland faced Belgium, with Białecki playing Kim Huybrechts in a singles match to start the contest. He lost the match 2–4, with Ratajski's loss to Dimitri van den Bergh sealing Poland's elimination.

At the beginning of July, he played at 2022 European Darts Matchplay. He won his first match on the European Tour with a 6–4 victory against Mervyn King. He lost 5–6 to Stephen Bunting in the second round after Białecki missed a match dart on double 20. At the end of the month, he took part in the soft-tip Polish Darts Championship. In the men's singles he beat Łukasz Wacławski in the final, winning his first senior Polish Darts Championship title and qualified for the second soft-tip EDF European Darts Championship in his career.

At the end of September 2022, he was selected by the national federation to participate in the 2022 WDF Europe Cup. On the second day of the tournament, he advanced to the finals of the pairs competition where he played together with Dariusz Marciniak. They were defeated by England's Joshua Richardson and Scott Williams 2–6.

He participated in the East Europe Qualifier for the 2023 PDC World Darts Championship. On his way to the final, he defeated Michele Turetta, Alexander Mašek and Rusty-Jake Rodriguez. In the final, he faced Christian Gödl and won 7–4.

In 2024, Białecki participated in the 2024 PDC Development Tour series. He finished 5th on the Development Tour Order of Merit, which meant that he received a two-year PDC Tour Card for the 2025 and 2026 seasons.

2025–present In his first year as a PDC Tour Card holder, Białecki won his maiden senior PDC title in July 2025, defeating Niels Zonneveld 8–6 in the Players Championship 22 final, the first time he had progressed past the last 16 of a Players Championship event. He became the third Polish player to win a PDC ranking title, after Krzysztof Ratajski and Radek Szagański.

Białecki made his second PDC World Championship appearance at the 2026 edition. Facing fourth seed Stephen Bunting in the first round, he recovered from 2–0 down to take the match to a deciding set, which he lost 4–2 in legs. Białecki broke two records on the 2026 PDC Development Tour: he became the first player to win four consecutive Development Tour titles, and compiled the longest unbeaten run in Development Tour history by winning 38 matches in a row. Exactly a year after his first ranking title, he won his second at Players Championship 26 in July 2026, defeating Mario Vandenbogaerde 8–6 in the final.
