The top two clusters share only 0% of their title tokens — “FK Bodø/Glimt vs. Molde FK” vs “Bitcoin vs. Gold vs. S&P 500 in 2026”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

This 30% probability indicates that Newell's Old Boys is expected to not win against Instituto AC Córdoba in an upcoming match. The current assessment reflects the relative strength disparity between the two Argentine clubs, with Instituto AC positioned as the likely favorite. Key factors that could shift this probability include recent team form, head-to-head historical performance, player injuries or absences, and home-field advantage. The resolution of this market depends on the match outcome, which will be determined once the scheduled fixture is played. Changes in the probability before kickoff would primarily reflect updated information about team conditions, betting market movement, or late-breaking news affecting either squad's composition or tactical approach.

  • Newell's Old Boys' recent performance record in the Argentine league and their current position in the standings
  • Instituto AC Córdoba's form and goal-scoring efficiency in recent matches
  • Head-to-head historical results between the two clubs over the past 2-3 seasons
  • Availability of key players for Newell's Old Boys, including injuries or suspensions affecting their starting lineup
  • Home or away designation for the match, as venue typically influences win probability by 5-15 percentage points in Argentine football

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.
