Heads-up — heterogeneous clusters
The top two clusters share only 25% of their title tokens — “Who will perform” vs “Who will be named in Epstein documents released in 2026”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis
This 15% probability indicates a modest chance that a major artist will perform at the closing ceremony of the 2026 FIFA World Cup in Rio de Janeiro. The estimate reflects limited public announcements about the event's entertainment lineup, with the World Cup taking place in mid-2026. Key drivers of this probability are official FIFA announcements regarding performers, the typical practice of revealing halftime and closing ceremony entertainment weeks before the event, and historical precedent from previous World Cups. The main catalyst will be FIFA's formal announcement of the closing ceremony performers, likely occurring in the months immediately preceding the tournament. Market pricing suggests traders assign higher confidence to other entertainment events, particularly the World Cup halftime show, where Coldplay trades at 59%. Uncertainty remains about whether Todo Mundo no Rio will feature a dedicated major performer versus a local or ensemble performance.
- ›FIFA typically announces halftime and closing ceremony performers 4-12 weeks before World Cup matches begin
- ›Historical World Cup closing ceremonies have featured both internationally recognized artists and regional/ensemble performances, creating ambiguity about what qualifies as 'performing'
- ›Coldplay trades at 59% for the halftime show while this event trades at 15%, suggesting market participants assign significantly lower probability to a major artist at the closing ceremony
- ›Brazil's artist roster and FIFA's preferred partnership with specific entertainment agencies historically influence final performer selection
- ›No public statements from FIFA about closing ceremony entertainment have been made as of June 2026, leaving the decision largely unannounced

How we compute these odds
SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.
For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.
Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
