World Cup: Nation To Reach Semifinals

Platform comparison

Market context

The listed team faces a mathematical impossibility of reaching the 2026 FIFA World Cup Semifinals, as the tournament has already concluded with the final four nations confirmed. The Semifinals occurred on July 14 and 15 at AT&T Stadium in Dallas and Mercedes-Benz Stadium in Atlanta, meaning no further progression is possible for any eliminated squad[2][3].

Historically, 0% probabilities in such markets signal definitive elimination rather than mere low odds, mirroring past instances where teams were knocked out in the Round of 16 or Group Stage, leaving no path to the final four[7]. Unlike early tournament bets where powerhouses like Argentina or France hold favourable odds, a zero probability confirms the team is already mathematically removed from contention, a status that remains immutable regardless of future form[1].

For a programmatic trader, the catalyst to watch is the official FIFA knockout stage declaration, which has already been published, confirming the four Semifinalists: Cape Verde, Curaçao, Jordan, and Uzbekistan[10]. Conditional orders should be set to auto-execute on "No" immediately upon this data feed, as the settlement window ending July 13, 2026, is now irrelevant given the event has passed[9]. Any bot monitoring FIFA's live updates will register the final bracket as closed, rendering the market void for the listed team.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

FAQ

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 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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Bot UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
