Market context

Japan and Iceland are scheduled to play a FIFA International Friendly on 31 May 2026 at 6:25 AM ET. The market in question tracks whether additional betting or prediction-market contracts will be created for this fixture beyond those already listed. The 0% implied probability suggests the crowd expects no further markets to materialise, though the settlement window extends to just after the scheduled kick-off time, leaving a narrow window for new offerings to be added and resolved.

Historical precedent shows that friendly matches between lower-ranked nations rarely attract secondary market proliferation on prediction platforms. Major sportsbooks typically concentrate liquidity on single moneyline, spread, and total-goals contracts for such fixtures, with ancillary markets (first goalscorer, corner counts, card totals) appearing only when aggregate betting interest justifies the operational overhead. Iceland's FIFA ranking (currently around 61st) and Japan's position (ranked 19th) place this encounter outside the tier of matches that routinely spawn multiple derivative contracts on retail prediction platforms.

Traders monitoring this contract should track whether either national federation announces squad rotations, injury updates, or tactical experiments in the weeks preceding the match—developments that sometimes prompt sportsbooks to launch novelty markets. The timing of the fixture, early in the North American morning, may also suppress market creation, as prediction platforms typically concentrate resources on evening European or prime-time US events. Any announcement from major platforms regarding expanded offerings for this friendly would likely emerge within 48 hours of the match date.

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

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.

Is this market available outside the US?

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
