Analysis

This contract measures the likelihood that Brandon Johnson, the Mayor of Chicago, will be arrested before January 2027. The 16% probability reflects a combination of ongoing political scrutiny and legal proceedings. The main factors driving this level include current federal investigations and prosecutorial priorities, weighted against the absence of formal charges to date. Any significant developments in ongoing cases or new investigations could shift the probability substantially. The most concrete upcoming milestone would be any announced indictments or major legal filings, which typically receive immediate market reaction. Political dynamics and enforcement priorities at both state and federal levels remain key variables affecting the resolution of this contract.

  • No formal criminal charges against Brandon Johnson have been filed as of May 2026, placing an arrest before January 2027 approximately 8 months away
  • Federal investigations and prosecutorial activities in Chicago politics have historically moved at varying speeds, with some cases resolved in under a year while others extend years beyond indictment
  • The current probability of 16% sits substantially lower than Letitia James (65%) and John Brennan (56%), suggesting market participants assess Johnson's legal exposure as materially lower than certain other political figures
  • Media reporting on active investigations or legal developments would be the primary catalyst for significant probability shifts in either direction
  • Prior arrests or indictments in Illinois politics serve as reference points for how quickly prosecutorial action can move from investigation to formal charges

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.
