World Cup: Nation To Reach Semifinals

Platform comparison

Market context

The 2026 FIFA World Cup is underway, with the knockout phase beginning in early July and the semifinals scheduled for 14 and 15 July in Arlington and Atlanta. For any listed nation, the current 0% implied probability to reach the semifinals signals that the team is either already eliminated, has not qualified, or is mathematically unable to advance from its group. This mirrors historical patterns where new debuting nations like Cape Verde, Curaçao, Jordan, and Uzbekistan face steep odds, often failing to progress past the group stage despite strong pre-tournament hopes [4][6].

Historically, only powerhouse teams such as Argentina, France, Spain, England, and Brazil have consistently reached the last four, with Spain holding a 39.0% pre-tournament chance to make the semifinals according to the Opta supercomputer [2]. Argentina, the defending champion, has surged to favourite status after dominating its group, while nations like Norway and Morocco are viewed as dark horses with modest but non-zero prospects [1][2]. The consensus heavily favours these top-tier teams, leaving little value in mid-tier contenders unless a contrainer angle emerges from unexpected group-stage upsets.

Traders should monitor the official knockout bracket released after the group stage, as dependencies on match results will determine elimination or advancement. Key catalysts include Spain’s return of Lamine Yamal, which has reshaped their contender status, and the USA’s advancement as Group D winner, setting a high-stakes clash with Bosnia and Herzegovina on 1 July [5][8]. Any delay in declaring the semifinal matchups beyond the 25 July deadline would trigger a “No” resolution, making schedule adherence a critical watchpoint [1]. Recent odds confirm Argentina at -165 and France at +100 as the clear leaders, with value potentially lying in underdogs like Colombia or Norway if group dynamics shift unexpectedly [1].

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

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'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.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 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.
