Which cities will Russia enter by December 31?

Platform comparison

Market context

Russian forces accelerated their summer offensive near Pokrovsk in the last 48 hours, making rapid advances just north of the town and pushing east of Kostyantynivka, while simultaneously applying pressure toward Kupyansk to encircle northern Donetsk[1]. This surge aligns with a broader methodical advance through the Luhansk and Donetsk regions, where Russia has claimed approximately 4,700 square kilometres of territory in 2025 alone, a figure analysts from the Institute for the Study of War (ISW) describe as double the size of Moscow[1]. The current 22% crowd-implied probability reflects a market weighing this sustained momentum against the resilience of Ukrainian defensive positions, which recently held firm around Kostiantynivka despite heavy offensive pressure[3].

Historically, similar probabilities in 2024 and 2025 preceded the capture of key logistics hubs like Pokrovsk only after Russian forces established a persistent "fortress belt" extending 50 kilometres through western Donetsk[1]. Comparable cases suggest that initial rapid gains often stall without the consolidation of buffer zones, yet the ISW notes Russia’s explicit aim to establish artillery range over Kharkiv, driving continued pushes south of Vovchansk and toward the Belgorod border[1]. Traders should monitor the persistence of ISW shading on the ArcGIS StoryMaps layer, as the market requires control to persist through the next full assessment cycle[8].

Key catalysts include the upcoming ISW Russian Offensive Campaign Assessment, with the latest update dated 12 July 2026 highlighting Ukraine’s new mechanised attacks and intermediate-range strike campaign[9]. Watch for announcements regarding Russian glide bomb strikes in Zaporizhia or Iskander-M cluster munition use in Dnipropetrovsk, which could signal shifts in offensive pressure or defensive attrition[3]. The settlement window extends to 31 December 2026, meaning traders must track whether current advances near Pokrovsk translate into permanent territorial shading before the year ends[1].

Methodology

We track Which cities will Russia enter by December 31? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
