The Turkish incumbent won the race with 52.16%, while Kılıçdaroğlu got 47.84% of the votes and 99.85% of the ballot boxes have been opened so far.
In a speech in Istanbul late Sunday, President Erdoğan said Türkiye's 85 million-strong citizens are the winners in the national elections that concluded today.
More than 64.1 million people were registered to vote, including over 1.92 million who earlier cast their ballots at overseas polling stations.
Nearly 192,000 ballot boxes were set up for voters across Türkiye.
On May 14, no candidate won the required 50% in the first round, triggering Sunday's runoff, although Erdoğan took the lead with 49.52%.
On that day, Erdoğan's People's Alliance also won a majority in parliament.
