Analysis

This 43% probability reflects the market's assessment that Giravanz Kitakyūshū will defeat Ōita Trinita in their upcoming match. The current level suggests near-parity between the teams, with slight skepticism about Giravanz as favorites. Key drivers include recent form in the J2 League, head-to-head historical performance, and squad availability. The contract data shows mixed signals: modest odds against both teams scoring (51¢) and relatively low confidence in either team's goal-differential outcomes. The main resolution catalyst is the scheduled match itself, which will determine the outright winner and settle the binary outcome. Market depth appears shallow given minimal 24-hour volume, suggesting limited recent activity and potentially wider bid-ask spreads than implied by the 43% midpoint.

  • Giravanz Kitakyūshū's current J2 League standing and recent match results relative to Ōita Trinita's form entering the fixture
  • Both teams' goal-scoring and defensive efficiency metrics this season, reflected in the 51¢ both-teams-to-score contract suggesting moderate-to-low combined scoring expectation
  • Head-to-head historical record between the clubs in direct matchups over the past 2-3 seasons
  • Injury or suspension status of key players for either team, affecting squad quality at time of match
  • Market volume concentration showing $0 24-hour volume across all contracts, indicating minimal recent position changes or new information flowing into pricing

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.
