Will Russia capture all of Kostyantynivka by July 31, 2026?

Prediction markets put the probability at 6%: Will Russia capture all of Kostyantynivka by July 31, 2026. Currently, markets see this as unlikely (6% YES). Russia’s armed forces aim to capture remaining 20% of ukraine’s donetsk region by year-end.

What’s Happening

Russia's military is intensifying its push to seize the remaining 20% of Ukraine's Donetsk region before the end of 2026, with recent tactical gains reported around Kostyantynivka and Pokrovsk. President Vladimir Putin said on June 28 that Moscow will press ahead with its battlefield aim of fully capturing four Ukrainian regions, rejecting Kyiv's ceasefire proposals. The question of whether Russia will fully capture all of Kostyantynivka by July 31 sits within this broader Donbas campaign, where Russia has occupied over 80% of the Donbas since 2014 but continues to grind through fortified urban belts.

Analysts caution that the pace of Russian advance argues against a rapid fall of Kostyantynivka. The Institute for the Study of War assessed on July 1 that Russian gains have been "largely gradual and creeping for over a year," with the rate of advance steadily decreasing since November 2025. Russian forces have also been unable to reverse Ukrainian counterattacks in the Kupyansk and Oleksandrivka directions from late 2025 and spring 2026. President Volodymyr Zelenskyy noted on June 29 that Russia's leadership has set 15 separate deadlines to fully capture Donetsk since the full-scale invasion began, none met. [ISW, Jul 2]

The structural factor determining whether Russia can capture all of Kostyantynivka by July 31 is the gap between stated objectives and the foot-paced reality of attritional warfare. After 1,588 days of fighting as of July 1, Moscow has not achieved its core aims, and Ukraine has taken the fight into Russian territory. For a full Russian capture of Kostyantynivka by July 31 to occur, the offensive would need to break sharply from the creeping tempo observed over the prior year — a discontinuity current front-line data does not support.
