5 clusters across 20 contracts.

These contracts were grouped by title similarity. The headline aggregate combines all clusters; verify the cluster you actually need before quoting a number.

Heads-up — heterogeneous clusters

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 market estimates a 30% probability that a match between CA Newell's Old Boys and Instituto AC Córdoba will see fewer than 1.5 goals scored. The odds suggest roughly a 70% chance of 2 or more goals in the fixture. Key drivers of this probability include the historical scoring patterns of both teams in their respective Argentine leagues, their recent form and defensive records, and any roster changes or injuries affecting key players. The primary catalyst will be the actual match result on the scheduled date, which will definitively resolve whether the total goals fall below or meet/exceed the 1.5 threshold. Market movement before kickoff would reflect updated team news, betting syndicate positioning, or shifts in perceived defensive capabilities. The low aggregate volume ($0 24h reported) suggests limited market participation currently, which could allow larger position changes to move odds more substantially than in higher-volume markets.

  • Recent goal-scoring rates for both CA Newell's Old Boys and Instituto AC Córdoba across their last 5-10 competitive matches
  • Defensive efficiency metrics: goals conceded per match for each team this season
  • Confirmed team lineups, injuries to key offensive or defensive players, and any recent tactical changes
  • Head-to-head historical scoring patterns if these teams have played previously
  • Betting market concentration: whether sharp money has established large positions that could shift quoted probabilities before kickoff

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.
