Tracks the leading outcome in a winner-take-all prediction market set with 6 outcomes.

Why this matters:
This probability reflects the likelihood that a specific artist will be selected to perform at the 2026 FIFA World Cup halftime show in the United States. The 9% represents the leading candidate's estimated probability based on market pricing. The main factors driving this level include FIFA's typical selection criteria (artist popularity, commercial appeal, and logistical feasibility), the artist's touring schedule and availability in mid-July 2026, and historical patterns from previous World Cup halftime performances. The uncertainty will narrow significantly once FIFA officially announces the performing artist, typically 4-6 months before the tournament. Market pricing reflects the distributed nature of this decision across approximately 20 distinct artist possibilities rather than concentration around a single frontrunner.

Key factors:
- Coldplay is trading at 52¢, indicating roughly 52% implied probability—substantially higher than the 9% leader listed, suggesting potential data misalignment or multi-artist contracts
- FIFA typically announces halftime performers 120-180 days prior to the World Cup final, creating a discrete resolution event around January-February 2026
- Artist availability and touring commitments in June-July 2026 are verifiable constraints that would affect selection feasibility
- The 24-hour trading volume is concentrated in Coldplay ($82) with minimal activity in alternatives, suggesting limited market depth for non-frontrunner outcomes
- Historical World Cup selections have favored artists with global commercial reach and no scheduled conflicts, narrowing the realistic candidate pool

## 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.
