Analysis

The 15% probability reflects market expectations that Napoli has roughly a 1-in-7 chance of winning Serie A in the 2026-27 season. This estimate positions Napoli behind Inter (30%), Atalanta (19%), Juventus (11%), and Milan (8%), suggesting the market views the defending or recent champion as more likely favorites. The probability reflects Napoli's recent competitive standing, squad stability over the next year, and transfer activity heading into summer 2026. Key factors that would shift this estimate include significant player acquisitions or departures, coaching changes, and early-season performance through autumn 2026. The resolution ultimately depends on final league standings in May 2027, with pre-season form and opening fixtures serving as early indicators of whether the market-implied probability remains justified.

  • Napoli's performance in the 2025-26 season and final league position, which establishes baseline competitiveness relative to rivals
  • Summer 2026 transfer window activity: significant arrivals or departures that affect squad depth, particularly in attacking or midfield positions
  • Coaching stability and tactical continuity—retention or replacement of the manager affects consistency of play and team cohesion
  • Injury record of key players throughout 2026-27, especially first-choice goalkeeper, defenders, and leading goal scorers
  • Head-to-head fixture outcomes against Inter, Atalanta, Juventus, and Milan in the first half of the season, which typically indicate title contention trajectory

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.
