Heads-up — heterogeneous clusters

The top two clusters share only 13% of their title tokens — “Boston Legacy FC vs Denver Summit FC Winner” vs “Will Boston Breach win”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

This probability represents the estimated likelihood that Boston Legacy FC will win their matchup against Denver Summit FC. The 35% aggregate probability reflects meaningful disagreement between venues: Kalshi traders price Boston's chances at 24%, while Polymarket traders estimate 39%, a 15-percentage-point gap suggesting uncertainty about team strength or upcoming match conditions. The contract volume is notably thin across most markets, indicating limited liquidity and potentially wider bid-ask spreads. Resolution depends on the match outcome, which will be determined on the scheduled game date. Factors like recent team performance, roster changes, head-to-head history, and venue conditions would typically influence such estimates, though current market depth is insufficient for high confidence in either direction.

  • Polymarket prices Boston's win probability 15pp higher than Kalshi, suggesting disagreement on valuation or access to different information sources
  • The Denver Summit FC winner contract on Kalshi trades at 33¢ (implying ~67% Denver probability), creating apparent inconsistency with the 35% Boston aggregate
  • Most secondary markets show zero 24-hour volume, indicating thin liquidity and potential pricing inefficiency
  • Draw probability is explicitly priced at 27¢ on Polymarket, suggesting material tie likelihood that may not be fully reflected in win-only contracts
  • The Boston Breach unrelated contract has $3,102 daily volume while Boston Legacy contracts show $60 or $0, indicating these teams operate in different liquidity tiers

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.
