Analysis

Andoni Iraola is currently the leading candidate to become Chelsea's next manager with a 24% implied probability, meaning bettors estimate roughly a one-in-four chance he fills the role. This reflects the multi-candidate nature of managerial transitions, where multiple qualified candidates typically compete for high-profile positions. The probability would rise if Iraola moves closer to formal negotiations with Chelsea or if competing candidates are ruled out through appointment elsewhere. It would fall if Chelsea publicly pursues alternative candidates or if Iraola secures his position at a current club long-term. The key catalyst remains Chelsea's decision timeline—whether the club accelerates a managerial search immediately or delays announcement, which would resolve uncertainty and consolidate probability mass around the eventual appointment.

  • Iraola's current employment status and contractual flexibility with his existing club
  • Number and caliber of competing candidates still in active consideration for the role
  • Public statements or reporting from Chelsea leadership regarding managerial search timeline and priorities
  • Track record of other manager-to-Chelsea transitions and typical decision velocity for the club
  • Whether other top clubs in Europe make competing managerial appointments, reducing the candidate pool

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.
