The article analyses the cycles of international system’s evolution and the ensuing world order shifts. Basing on Kondratiev waves theory and cycles of international system’s analysis, the author proposes that the period of 2025-2040 will correlate with the revolutionary phase of the global market’s development, which is typically characterized by profound and widespread geoeconomic and geopolitical shifts, leading to the whole international system’s reformatting. The structural similarities, observed in previous revolutionary phases of the global market’s history, as well as monitoring of some recent developments in a number of regions, prompt the author to predict a high probability of systemic reforms at the major nations’ and global levels during the period of 2025-2033.
