Analysis

This contract estimates a 35% probability that Gamba Ōsaka will score more goals than Vissel Kōbe in an upcoming J-League match. The probability reflects relative team form, home-field advantage if applicable, and recent scoring patterns. Movement in this market would depend on team selection announcements, injury updates to key players, or recent performance trends in the days before the match. The primary catalyst for resolving this uncertainty is the match itself, which determines actual goals scored. Related Nagoya Grampus contracts show market participants also weighting defensive strength; the relatively low 10-cent price on Vissel conceding 2.5+ goals suggests defensively solid opponents are expected.

  • Gamba Ōsaka's recent goal-scoring rate and conversion efficiency in J-League play
  • Vissel Kōbe's defensive record and goals-against average over recent matches
  • Team lineup confirmation and availability of key attacking or defensive players before match day
  • Historical head-to-head scoring patterns between these two clubs
  • Match venue and typical home-field scoring advantage, if applicable

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.
