NATO/EU troops fighting in Ukraine by 2025?

Platform comparison

Market context

No active NATO or EU combat deployment to Ukraine has been publicly confirmed in the past 24-48 hours, and the market is still trading at 0% because the bar for a Yes is very high: it requires officially acknowledged, active military personnel from a NATO or EU state entering Ukraine for combat-related purposes, not just aid, training, or command support. NATO continues to describe its role as supplying weapons, ammunition and other military equipment, while longstanding alliance policy has been to avoid deploying combat troops into Ukraine.[2][15]

That makes this a low-probability market unless a major policy break occurs. Comparable episodes have usually produced headlines about support, advisers, or possible future security guarantees rather than confirmed combat troops. Reuters/AP reporting in 2024 noted that NATO Secretary-General Jens Stoltenberg said there were “no plans for NATO combat troops on the ground in Ukraine”, and several European leaders reiterated that they would not send soldiers; even where discussion has shifted, it has often centred on post-ceasefire guarantees rather than current battlefield deployment.[3][8][9] Reports of foreign personnel already in Ukraine have generally involved training, intelligence, arms-control, or other non-combat roles, which would not satisfy this market’s wording.[4][12]

For traders, the main catalysts are formal government announcements, summit language from NATO or EU leaders, and any bilateral agreement that explicitly authorises uniformed personnel to operate inside Ukraine in a combat role. The closest watchpoints are statements from France, the UK, Germany, Poland and the Baltic states, plus any change in the “coalition of the willing” discussion around security guarantees after a ceasefire or peace plan.[8][13] Absent a public and specific commitment, the default reading remains no combat deployment before the end-2025 settlement window.

UK Frequently Asked Questions

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
