Analysis

This market is asking whether a soccer match between Hokkaidō Consadole Sapporo and RB Ōmiya Ardija will produce more than 4.5 total goals. The current 61% probability favoring over 1.5 goals (reflected in the leading contract price) suggests traders believe a low-scoring outcome is more likely, with the 33¢ price on the over 4.5 contract indicating skepticism about a high-scoring game. The probability distribution across multiple goal thresholds reflects uncertainty about both teams' offensive and defensive capabilities relative to historical performance. The match result will provide definitive resolution once played. Market depth appears limited, with zero 24-hour volume across contracts, suggesting thin liquidity and potentially wider bid-ask spreads.

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.
