Market context
Ukraine's political system has experienced significant instability since 2014, yet successful military or security-force coups remain absent from its post-independence record. The 7% implied probability reflects the low historical baseline for such events in the region, though Ukraine's ongoing war with Russia, fractured military command structures, and periodic tensions between civilian and military leadership create theoretical pathways for internal power seizures. A coup attempt would require coordinated action by substantial state actors—military units, intelligence services, or presidential guards—rather than isolated mutinies or civilian protests, a threshold that has not been crossed despite multiple political crises.
Comparable cases from post-Soviet space inform the baseline risk. Georgia's 2008 military defeat and subsequent political turbulence did not produce a coup; Moldova's repeated colour revolutions remained civilian-led. Ukraine's 2004 Orange Revolution and 2013–2014 Euromaidan were mass mobilisations, not state-actor seizures. The current conflict with Russia has consolidated rather than fractured the security establishment around President Zelenskyy, though military-civilian friction over conscription, strategy, and resource allocation persists. Historical precedent suggests Ukrainian institutional actors have preferred political manoeuvre to forcible takeover.
Traders should monitor military leadership changes, statements from senior commanders regarding civilian authority, and any public disputes between defence ministry and armed forces command. Announcements of significant personnel reshuffles, particularly within the General Staff or Security Service (SBU), warrant attention. The settlement window extends through 2026, capturing potential post-war instability if conflict dynamics shift materially. Recent reporting from Reuters and local Ukrainian media tracks factional tensions, though no credible reporting has suggested imminent coup planning as of late 2024.

UK Frequently Asked Questions
- Is Polymarket legal in my country?
- Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.
- Is Polymarket regulated by the UKGC?
- No. Polymarket is not licensed by the UK Gambling Commission (UKGC). It is a decentralised prediction market operated under US regulation. UK traders can use it but do not benefit from UKGC dispute resolution or player protection requirements.
- What are the HMRC tax rules on Polymarket profits for UK traders?
- Polymarket profits are treated as cryptocurrency disposal events by HMRC. Each USDC settlement is a taxable event subject to Capital Gains Tax (CGT). For 2026/27, the CGT rate is 18% (basic rate) or 24% (higher rate). The annual CGT exemption is £3,000. Report via HMRC Self Assessment if your total crypto gains exceed £3,000 or proceeds exceed £50,000.
- Does Polymarket KYC apply to UK users?
- Yes. Polymarket requires KYC (Know Your Customer) verification for all users, including UK residents. You must provide a government-issued photo ID and a selfie. The process typically takes 5–10 minutes via their ID verification provider.
- What is the legal difference between Polymarket and Betfair Exchange for UK traders?
- Betfair Exchange is UKGC-licensed, meaning UK consumer protections apply and winnings are typically tax-free. Polymarket is not UKGC-licensed — it operates under decentralised blockchain rules. Profits from Polymarket are subject to HMRC CGT as crypto disposals. Choose based on your regulatory preference and tax situation.
