World Cup: Nation To Reach Semifinals

Platform comparison

Market context

The 2026 FIFA World Cup is underway, with the knockout stage now determining which nations advance to the semifinals in Dallas and Atlanta. The listed team currently holds a 0% chance of reaching that stage, implying they have been mathematically eliminated or are not yet qualified for the tournament. This mirrors historical precedents where nations like Switzerland in 2014 or Croatia in 2018 were initially dismissed before making deep runs, though such cases require active qualification and no prior elimination. In contrast, teams eliminated in the group stage of previous World Cups, such as Italy in 2010, never recovered, reinforcing how early exits lock in "No" outcomes permanently.

Traders should monitor official FIFA announcements regarding qualification status, group-stage results, and potential cancellations, as the settlement window closes on 13 July 2026. Recent fixtures show Portugal and England progressing, while teams like Ghana and Panama face elimination, per ESPN’s live match updates[8]. Divergence between platforms is notable: Polymarket displays decimal odds (e.g., 1.00 for 0% probability), whereas Kalshi and Betfair use implied probability percentages and require KYC verification, creating fee and access disparities. Smarkets offers lower fees but limited liquidity on niche sports markets, while Betfair’s higher liquidity may not reflect real-time elimination data as swiftly as Polymarket’s on-chain resolution.

Methodology

We read World Cup: Nation To Reach Semifinals from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
