Tracks the leading outcome in a winner-take-all prediction market set with 2 outcomes.

Why this matters:
This market estimates the likelihood that Messi will out-contribute Ronaldo in combined goals and assists during the 2026 FIFA World Cup. At 46%, it reflects modest confidence in Messi's edge, with the runner-up outcome at 28%. The probability sits below 50-50 despite Messi being favored, suggesting meaningful uncertainty about both players' participation levels, fitness, and tournament performance. Messi's participation is heavily priced (93% on Polymarket), but his actual goal-contribution rate relative to Ronaldo depends on playing time, age-related decline, and team performance. The market will sharpen as the tournament approaches in June 2026, when squad selections are finalized and early-round performances become visible. Key drivers include confirmation of both players' selection, their roles within their respective teams, and how many minutes each receives in group and knockout stages.

Key factors:
- Messi's playing time and fitness status at age 39, relative to Ronaldo's expected availability and minutes at 41
- Both players' team squad depth and attacking support structure in the tournament
- Historical goal-contribution rates in international tournaments for players in their late 30s and 40s
- Whether either player is selected as a primary striker versus deployed in supporting attacking roles
- Tournament progression of Argentina and Portugal, which affects cumulative minutes and match opportunities

Contracts:
- Will Lionel Messi or Cristiano Ronaldo have more goal contributions in the FIFA World Cup?: Lionel Messi — 91¢ Kalshi $3K (weight 25%)
- Will Lionel Messi or Cristiano Ronaldo have more goal contributions in the FIFA World Cup?: Cristiano Ronaldo — 8¢ Kalshi $8K (weight 75%)

## 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 Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
