The market “Will Russia capture Kostyantynivka by July 31?” experienced a sharp drop in its YES price over the last 24 hours, falling 22.0 percentage points from approximately 62.5% to 40.5% on Polymarket. This represents a significant repricing of the probability that Russia will capture the city within the stated timeframe.
Notably, whale activity diverged from this downward price move. Large traders bought $32K worth of YES contracts and sold $16K, resulting in a net $16K inflow into YES positions. This contrasts with the price decline, indicating that whales were increasing exposure to the YES outcome even as overall market prices trended lower.
The 24-hour volume on Polymarket for this market was $23K, which is below the whale buy volume, suggesting that the largest trades influenced the price movement but did not fully align with the direction of the price change. Across the market’s lifetime, total volume stands at $239K with 639 unique traders participating.
Additionally, the Polymarket YES price at 40.5% differs from the Polydata on-chain midpoint of 29.0%, highlighting some discrepancy between the exchange price and on-chain data.
This divergence between whale flow and price action signals a complex market dynamic where large traders appear to be betting against the prevailing price trend. The substantial price drop combined with whale buying suggests differing interpretations of the likelihood of Russia capturing Kostyantynivka by July 31.
