Which cities will Russia enter by December 31?

Platform comparison

Market context

Russia’s campaign to seize additional Ukrainian cities by the end of 2026 hinges on whether its forces can overcome entrenched defences and sustain offensive momentum after failing to meet earlier Kremlin deadlines for capturing Donetsk and Luhansk oblasts[1][3]. The 22% crowd-implied probability reflects a market that acknowledges Russia’s continued pressure but remains sceptical of a breakthrough before the settlement window closes, especially given that Russian forces made no confirmed advances on 30 June 2026 despite launching 154 drones overnight[3].

Historically, Russian territorial gains in Ukraine have been incremental and often reversed; for instance, ISW confirmed Russian control over Pokrovsk and Rivne only after prior offensives ended, while towns like Novoserhiivka were taken but did not lead to rapid expansion into major cities[4]. Comparable cases show that even when Russia claims “new territorial gains”, sustained control of urban centres remains rare without overwhelming artillery and manpower advantages, which have not materialised in 2025–2026[1][2].

Traders should monitor ISW map updates for persistent shading indicating Russian control, as temporary incursions do not qualify for settlement[1]. Key catalysts include Kremlin announcements on military deadlines, which have repeatedly proven unrealistic, and the frequency of long-range drone strikes targeting Ukrainian energy infrastructure, which could degrade defensive capacity[3][8]. Any shift in Russian subordinate main efforts—particularly toward encircling northern Donetsk or approaching Kharkiv within tube artillery range—would significantly alter the odds[6].
