Analysis

This market is pricing a 31% chance that Chapecoense defeats Red Bull Bragantino in an upcoming match. The probability reflects moderate uncertainty, with a 5 percentage point gap between Polymarket (35%) and Kalshi (30%), suggesting some disagreement across trader bases. Bragantino is favored as the likely winner at current odds. The main drivers of this probability are each team's recent form, head-to-head history, and squad availability. The match itself will resolve this uncertainty definitively—either Chapecoense wins outright or they don't. Pre-match factors like team news, injuries, or lineup changes could shift the probability in the days leading up to kickoff, while live performance during the match will determine the final outcome. The cross-venue gap suggests traders on Polymarket see slightly elevated value in a Chapecoense victory compared to Kalshi participants.

  • Chapecoense's recent league form and current standing relative to Bragantino's position in the Brazilian football table
  • Head-to-head record between the two clubs over the past 3-5 meetings, including goals scored and defensive records
  • Availability of key players—injuries, suspensions, or absences for either squad in the days before the match
  • Home or away status for this fixture and each team's record at their respective venues this season
  • Polymarket traders pricing Chapecoense 5 percentage points higher than Kalshi traders, indicating potential disagreement on underlying team strength or recent momentum

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.
