Analysis

This market reflects traders' assessment that RB Ōmiya Ardija and Iwaki FC have roughly equal likelihood of winning their matchup, with one outcome priced 17 percentage points higher than the second-place option. The current 50% probability suggests no clear consensus favorite, which typically reflects either balanced team strength, limited recent data, or disagreement about lineup or form. Movement in this probability would depend on updates to team injury status, recent results, or weather conditions affecting play. The match itself serves as the resolution event, making pre-match information like team news and starting lineups the primary catalysts for probability shifts in the hours before kickoff.

  • Relative league position and recent win-loss records of both RB Ōmiya Ardija and Iwaki FC in their current competition
  • Availability of key players due to injuries, suspensions, or other absences heading into the match
  • Historical head-to-head record and goal differential in direct matchups between the two teams
  • Market depth and trading volume relative to other soccer markets, indicating confidence level among traders
  • Distance traveled and schedule fatigue if one team is playing their second match in a short window

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.
