16% — 2026 FIFA World Cup Winner Leader: France at 16% · Polymarket 16% · 8 contracts · $5.8M volume · medium confidence Updated 2026-06-08 07:51:02 UTC Tracks the leading outcome in a winner-take-all prediction market set with 8 outcomes. Why this matters: This 20% probability represents the combined market estimate that France will win the 2026 FIFA World Cup. The estimate reflects strong recent performance by France and a relatively balanced competitive field among top contenders. Market pricing is driven primarily by squad strength and historical tournament performance; the probability would shift based on pre-tournament injury announcements, major roster changes, or qualification/friendly match results. The tournament itself begins in mid-June 2026, and any significant squad disruptions or form changes in the months leading up to qualification completion will likely move prices substantially. Early-stage friendly matches and confederation playoffs occurring through May-June 2026 will provide concrete data on current team strength. Key factors: - France won the 2022 World Cup and reached the final in 2018, providing documented recent success that supports elevated market valuation compared to longer-shot competitors - Polymarket contracts price France at 17¢ while Kalshi averages 35¢ across 5 contracts, indicating significant disagreement between venues that reflects genuine uncertainty in valuation methodology or risk appetite differences - Brazil, Spain, England, and Portugal collectively represent 44¢ in Polymarket pricing, suggesting the market views the tournament as genuinely competitive with no dominant favorite - 24-hour trading volumes exceed $190,000 on each top contract, indicating sufficient liquidity and market confidence in pricing rather than illiquid outlier valuations - France squad composition and injury status through May 2026 represents a concrete, observable factor; any retirement announcements from key players or major injuries would directly resolve current uncertainty Contracts: - World Cup Winner : France — 16¢ Polymarket $584K (weight 10%) - World Cup Winner : Spain — 16¢ Polymarket $437K (weight 8%) - World Cup Winner : England — 11¢ Polymarket $554K (weight 10%) - World Cup Winner : Portugal — 10¢ Polymarket $993K (weight 17%) - World Cup Winner : Argentina — 9¢ Polymarket $220K (weight 4%) - World Cup Winner : Germany — 5¢ Polymarket $833K (weight 14%) - World Cup Winner : Netherlands — 4¢ Polymarket $940K (weight 16%) - World Cup Winner : Norway — 3¢ Polymarket $1.2M (weight 21%) --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours. ## SF Signal - SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration. - No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only. --- *Last verified: 2026-06-08T07:20:11.933Z* By SimpleFunctions — https://simplefunctions.dev/ Cite as: "16% per prediction markets (SimpleFunctions, June 2026)" Canonical: https://simplefunctions.dev/answer/fifa-world-cup-winner Full data: https://simplefunctions.dev/api/public/query?q=2026%20FIFA%20World%20Cup%20Winner Provider: SimpleFunctions — https://simplefunctions.dev
