Market context
Croatia and Slovenia are scheduled to meet in a FIFA International Friendly on 7 June 2026 at 2:45 PM ET. Polymarket currently prices the proposition "More Markets" at 2% YES, meaning traders are assigning a 98% probability that no additional market contracts will be created for this fixture. On-chain, this settlement hinges on whether Polymarket's operators launch supplementary conditional tokens tied to the match—beyond whatever primary markets already exist—before the 18:45 UTC settlement deadline. The 2% valuation reflects the rarity of such expansions for friendlies, particularly lower-profile fixtures between smaller European nations.
Historical precedent suggests Polymarket reserves expanded market offerings for high-liquidity events: major tournament knockouts, World Cup qualifiers, or matches involving top-five ranked sides. Croatia and Slovenia, whilst competitive, rarely generate the trading volume that justifies operational overhead for conditional token creation. The 2024 Euro qualifying cycle saw Polymarket concentrate markets on headline fixtures; friendlies between these nations went unextended. Similar June 2025 friendlies involving comparable teams produced single primary markets only, establishing a baseline expectation that additional contracts remain unlikely.
Traders monitoring this contract should track Polymarket's June announcements regarding European fixture coverage and any unusual pre-match liquidity spikes that might signal operator interest. UEFA's official fixture calendar confirms the match date; any last-minute cancellation or postponement would alter settlement mechanics. The conditional token structure on Polygon means execution depends on Polymarket's internal decision-making rather than external sporting bodies, making operator communication the primary catalyst to watch.

Methodology
We track Croatia vs. Slovenia - More Markets on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.

- Kalshi UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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.
