The probability that Russia will capture Kostyantynivka by July 31 surged 35.0 percentage points in the last 24 hours, climbing from 26.5% to 61.5% on Polymarket. This move reflects a significant revaluation of the event’s likelihood within one day.
Whale trading activity supported the price increase, with net inflows of $27K into YES contracts. Whale buy volume totaled $50K against $23K in sells, involving 101 unique whale participants. This alignment between whale flow and price movement indicates coordinated buying pressure rather than a divergence.
Polymarket’s 24-hour volume on this market was $49K, nearly matching whale buy volume alone, while the market’s lifetime volume stands at $202K with 587 unique traders overall. Notably, the on-chain mid-price from Polydata is 43.5%, substantially lower than Polymarket’s current YES price of 61.5%, suggesting some discrepancy between on-chain data and market prices.
The combined surge in odds and whale participation signals a rapid shift in market sentiment toward a higher perceived probability of Russian forces capturing Kostyantynivka by the end of July. This repricing and whale support highlight the market’s responsiveness to new information or changing assessments of the situation on the ground.
