Market context
Ukraine's political system has remained formally intact despite two years of full-scale Russian invasion, though military and security structures have undergone significant centralisation under wartime command. A coup attempt—defined here as a coordinated effort by state actors to seize control unlawfully—would represent a sharp departure from Ukraine's post-2014 trajectory of institutional resilience, even as the country has endured extraordinary stress. The 7% implied probability reflects the low baseline risk of such an event, though traders should distinguish between isolated security incidents and the threshold of a genuine coup attempt requiring coordination across military or security factions.
Historical precedent offers limited direct comparison. Ukraine experienced the 2004 Orange Revolution and 2013–2014 Euromaidan upheaval, both driven by mass protest rather than state-actor conspiracies. Military factions have occasionally clashed with civilian leadership—notably tensions between President Zelenskyy and General Valery Zaluzhny in 2023–2024—but these remained within institutional bounds. Comparable post-Soviet states have seen genuine coup attempts (Georgia 2008, Belarus 2020), though neither Ukraine's current military command structure nor its security apparatus has demonstrated the factional cohesion required for such an action. The market's 7% probability sits above the historical baseline but below scenarios involving state collapse or foreign occupation.
Traders monitoring this market should track command-structure announcements, military leadership changes, and statements from security services. Recent reporting from Reuters and BBC Ukraine has documented tensions between civilian and military authorities over mobilisation policy and strategy, though these remain within normal civil-military friction. The settlement window extends to end-2026, capturing any potential instability during continued wartime operations. Across platforms, Polymarket's 0.07 decimal odds and Kalshi's equivalent pricing reflect consensus scepticism, though liquidity varies; Betfair and Smarkets show comparable implied probabilities with differing fee structures affecting effective odds for traders.
Methodology

Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
