Heads-up — heterogeneous clusters

The top two clusters share only 7% of their title tokens — “Will New York” vs “Will Colorado have the longest losing streak in the 2026 Pro Baseball regular season”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

This probability indicates roughly a 1-in-4 chance that Philadelphia has the longest single losing streak of any Major League Baseball team during the 2026 regular season. The market is pricing in historical baseline rates for such extreme performance, adjusted for Philadelphia's roster composition and recent competitive standing. Factors supporting a higher probability would include significant injuries to key players, unexpected front-office turnover, or systematic performance collapse. Conversely, roster stability and competitive spending would lower this likelihood. The outcome will be determined over the full 162-game regular season, with clarity emerging by early October 2026 when final standings confirm which team experienced the worst consecutive-game drought.

  • Philadelphia's 2025 season performance and current roster depth relative to other MLB teams
  • Historical frequency of longest losing streaks by team and whether Philadelphia has disproportionately experienced such streaks
  • Early 2026 season results through June-July, indicating whether Philadelphia shows vulnerability to extended slumps
  • Injury severity to position players or starting pitchers during the regular season
  • Off-season roster changes and competitive balance shifts across the 30-team league

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.
