The probability that Russia will capture Kostyantynivka by July 31 rose sharply by 33.0 percentage points on Polymarket over the past 24 hours, climbing from 33.5% to 66.5%. This significant repricing reflects a rapid shift in market sentiment toward the likelihood of this event.
Whale activity aligned with this price movement, with a net $18K flowing into YES contracts during the same period. Whale buy volume was $34K, outpacing $16K in sell volume, spread across 75 unique whale traders. This buying pressure from large traders supported the upward move in odds, indicating conviction behind the shift.
Despite the sharp increase in Polymarket’s YES price, Polydata’s on-chain overview price remains lower at 43.5%, suggesting some divergence between on-chain mid-market data and Polymarket’s live price. The market’s 24-hour volume was $26K, contributing to lifetime volume of $171K with 538 unique traders participating.
The combined price surge and whale buying activity signals a strong market reassessment of Russia’s chances to capture Kostyantynivka within the specified timeframe. Whales moving in concert with price changes adds weight to the shift, reflecting a growing consensus rather than isolated speculation.
