Analysis

This 35% probability reflects market expectations that Gamba Ōsaka will achieve a positive result (win or draw) in an upcoming match against Vissel Kōbe. The current level suggests traders view Vissel Kōbe as slight favorites, likely based on recent form, head-to-head records, or home-field advantage. Key factors influencing this probability include each team's current league position and recent performance streak, injury status of key players, and whether the match is played at a neutral venue or one team's home ground. The probability will shift materially once the match is played, with outcome data immediately resolving the uncertainty. Until then, any significant roster changes, coaching announcements, or official confirmation of venue could move the market. Low trading volume on related contracts suggests limited liquidity, which may cause wider bid-ask spreads and larger price swings from individual trades.

  • Current league standings and recent match results for both Gamba Ōsaka and Vissel Kōbe in the 2026 season
  • Confirmed starting lineups and availability of key players, particularly any injuries or suspensions announced before match day
  • Whether the match is played at Gamba's home venue, Vissel's home venue, or a neutral location
  • Head-to-head historical performance between these teams over the past 2-3 seasons
  • Match date and time confirmation, as any postponement or schedule change could affect team preparation and odds adjustment

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.
