Analysis

This 46% probability represents the combined market assessment that Inter Milan will win the 2026 Coppa Italia. The estimate reflects Inter's strong domestic performance and squad depth, balanced against competition from other Italian clubs like Lazio. A 9-percentage-point gap exists between venues, with Polymarket pricing Inter's chances at 50% versus Kalshi at 41%, suggesting some disagreement about Inter's relative strength. The probability would shift based on team injuries, form changes, or knockout-stage matchups as the tournament progresses. The Coppa Italia final, typically held in May, represents the key resolution point for this market, though earlier eliminations would also clarify outcomes.

  • Inter has won the Coppa Italia in 4 of the last 8 seasons (2019-20, 2021-22, 2023-24, 2024-25), indicating consistency among Italian competitors
  • Low 24-hour trading volume on most contracts ($0-3 across venues) reflects limited recent activity and potentially wide bid-ask spreads
  • Lazio is priced significantly lower (12-32 cents) despite being Serie A's second-place team, suggesting bookmakers view tournament format or knockout structure as favoring Inter
  • The 9pp venue divergence indicates different market participant confidence levels or potential data discrepancies between platforms
  • Polymarket's Inter contract at 68 cents shows stronger confidence than Kalshi's 70 cents despite lower overall platform probability, reflecting contract-level pricing variations

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (72% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

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.
