Russian forces have made incremental gains in Donetsk Oblast, including the reported seizure of Markove on September 23, 2026, while Ukrainian units conducted counteradvances in the Kupyansk, Chasiv Yar, and other sectors. Both sides intensified drone and missile strikes on energy infrastructure, ports, and refineries through mid-September, with Ukraine targeting facilities deep inside Russia and Russia hitting Ukrainian cities and grids ahead of winter. Kremlin officials rejected U.S.-Ukrainian proposals for a limited energy ceasefire during UNGA meetings, reiterating demands for broader capitulation, as frontline progress remains limited to small settlements rather than major urban centers. These battlefield dynamics and stalled diplomacy shape trader assessments of potential city entries by year-end.
