66% — FIFA World Cup Group I Winner
Leader: France at 66% · Polymarket 66% · 3 contracts · $17K volume · medium confidence
Updated 2026-06-08 07:51:11 UTC

Tracks the leading outcome in a winner-take-all prediction market set with 3 outcomes.

Why this matters:
This represents the probability that France will finish first in Group I of the FIFA World Cup, currently priced at 77% by the leading market contract. France enters as a strong favorite based on their tournament history and squad depth. The probability would move higher if France wins early matches decisively, and lower if they face unexpected defeats or key injuries. The next World Cup match in Group I will provide concrete evidence to test this assessment. Market participants are pricing in France's historical performance and current roster strength, though any group upset would immediately repriced this significantly downward.

Key factors:
- France's squad composition and recent tournament performance form the baseline for this 77% assessment
- Early-tournament match results in Group I will directly test whether France performs to expectation or underperforms
- Injuries to key French players before or during group play would be a material downward catalyst
- The volume concentration in the France contract ($1350 24h volume) relative to other Group I outcomes suggests some bilateral disagreement on whether 71¢ (Polymarket price) fairly values France
- Historical precedent shows that top-seeded teams in World Cup groups win the group approximately 65-75% of the time, making 77% consistent with France's elite ranking

Contracts:
- World Cup Group I Winner: France — 66¢ Polymarket $16K (weight 93%)
- World Cup Group I Winner: Norway — 24¢ Polymarket $663 (weight 4%)
- World Cup Group I Winner: Senegal — 11¢ Polymarket $591 (weight 3%)

## 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.
