This is a market on the likelihood of Russia capturing Kostyantynivka by a specific date.
Russian forces have conducted a prolonged grinding offensive against Kostyantynivka, a key transport and defensive hub in Ukraine’s Donbas “fortress belt,” as their main effort in the 2026 spring-summer campaign. Tactical Russian infiltrations reached eastern, southern, and western districts by early July, prompting Kremlin claims of full capture that Ukrainian officials and independent assessments rejected, with Ukrainian units continuing to hold central and northwestern sectors and clearing infiltrators. Both sides rely heavily on drones for logistics interdiction and strikes, while Russian infantry advances remain incremental and costly amid Ukrainian defensive fire. The contested status and associated information operations continue to shape trader views on whether incremental Russian gains will produce consolidated control by any near-term resolution date.
