As Yubileyny grew, the nearby city of Korolyov also developed dynamically. Ultimately, with an exception of a segment of a border with the Yaroslavl Highway, Yubileyny became completely surrounded by the territory of Korolyov. This segment constituted the northern border of a ribbon-shaped area of land that was annexed by the town with the sole purpose of establishing a border with an entity other than Korolyov. Nevertheless, effective June 2014, Yubileyny was merged into Korolyov and ceased to exist as a separate town.
