Analysis

This probability reflects traders' assessment that the Chicago pro football team will relocate somewhere within Illinois rather than to Indiana or remain in its current location by the 2028 season opener. The 51% probability indicates substantial uncertainty, with relocation to Indiana at 35% and no-move scenarios accounting for the remainder. The main drivers are ongoing stadium negotiations, local and state funding commitments, and NFL ownership decisions. A critical catalyst would be any official announcement from team ownership, the NFL, or Illinois/Chicago officials regarding stadium plans or relocation intent. Trading volume on the Illinois contract ($84 in 24-hour volume) remains modest, suggesting limited recent news flow. The outcome hinges on whether funding gaps push the team toward new Illinois locations or whether Indiana incentives prove more attractive than staying put.

  • Current stadium lease terms and renovation feasibility—whether Soldier Field upgrades are pursued or deemed insufficient
  • Illinois and Chicago political commitment to funding mechanisms for a new stadium or renovated facility within the state
  • Competitive offer structure from Indiana versus the cost and complexity of relocation within Illinois geography and market
  • NFL ownership stance and timeline for requiring stadium resolution, typically tied to capital expenditure deadlines or lease expiration
  • Real estate availability and zoning approval pace for potential new stadium sites within Illinois metropolitan areas

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.
