Market context

Russia’s spring-summer 2026 offensive has largely stalled, with Ukrainian forces halting advances and Russian gains in May 2026 covering only a fraction of the territory secured in May 2025[1]. Over the past six months, Russian forces have lost 281.1 square kilometres of controlled territory while gaining just 40.64 square kilometres, underscoring a net contraction rather than expansion[1]. This mirrors 2025 patterns where Russia claimed roughly 4,700 square kilometres—double Moscow’s size—but faced fierce resistance that prevented decisive breakthroughs in the Donbas[2]. With current crowd-implied probability at just 1% for Russia entering Sloviansk by June 30, the market correctly reflects this historical inertia: Russian infiltration missions near Lyman and Kostyantynivka have repeatedly failed to establish lasting control[3][5].

Traders should monitor ISW’s daily frontline updates, particularly shading indicating “Assessed Russian Infiltration” or “Control” around Sloviansk’s outskirts, as persistence through the next full update is required for resolution[4]. Key catalysts include any renewed Russian assaults southwest of Dobropillya or northwest of Pokrovsk, where ISW notes infantry are being pulled forward for intensified operations[3]. Additionally, long-range drone strikes targeting Ukrainian logistics—such as the 265 Shahed-type drones launched on 31 May–1 June—could disrupt defensive lines and enable limited advances[1]. Recent Ukrainian strikes on Russian control points near Pochayevo and Gorky may also alter frontline dynamics, making ISW’s 24 June map update critical for assessing near-term risk[3].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
