Analysis

This market reflects a 31% probability that CA Rosario Central will win by more than 2.5 goals against Club Libertad. The current pricing suggests Club Libertad is favored, with the spread-based contracts showing lower prices on Rosario Central's largest victory margin. The probability sits between the moneyline odds (65% for Rosario Central to win outright) and tighter spreads, indicating market participants expect either a close result or a modest Libertad victory. The main drivers of this probability are the relative strength of both teams in South American club competition, their recent form, and how goals are typically distributed in Copa Libertadores or domestic cup matches. The resolution depends entirely on the match result itself, which will determine whether Rosario Central achieves a margin exceeding 2.5 goals.

  • The moneyline contract prices Rosario Central at 65 cents (favored to win), yet the -2.5 spread is only 20 cents, suggesting markets expect a narrow margin if Rosario Central wins
  • Club Libertad's -2.5 contract trades at 6 cents, indicating low probability of a large Libertad victory; markets view a big loss by Rosario Central as unlikely
  • Recent trading volume concentrates on the -2.5 contracts ($306 in 24h volume), with minimal volume on tighter spreads, suggesting uncertainty about final margin rather than match outcome
  • Both teams compete in South American continental competition where defensive structures typically limit large victory margins
  • The 31% probability implies markets assign roughly 2-to-1 odds against Rosario Central winning by more than 2.5 goals despite favoring them to win outright

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.
