Analysis
Markets are pricing a 65% probability that Bill Belichick departs his current coaching role by January 1, 2028, with higher confidence (31% probability) that an exit occurs before January 1, 2027. The probability reflects ongoing speculation about Belichick's tenure, influenced by team performance, contract terms, and reported discussions about his future. The 2026 NFL season serves as the primary catalyst—Win-loss records, playoff positioning, and any official statements from team ownership or Belichick himself will likely resolve much of this uncertainty. Near-term performance in September through December 2026 will be the key driver; sustained poor results or public conflict typically accelerates coaching departures, while playoff contention or strong team trajectory would push probabilities lower.
- ›Current 2026 NFL season results and playoff trajectory: poor performance or team dysfunction would increase exit probability; playoff contention would decrease it
- ›Expiration or renegotiation of Belichick's contract terms and whether ownership has expressed confidence or concern publicly
- ›Statements from team ownership or Belichick regarding his long-term commitment; any reported negotiations with other teams would meaningfully raise exit probability
- ›Historical coaching tenure patterns: NFL coaches at Belichick's age and experience level typically face higher turnover pressure if team performance declines
- ›Absence of recent contract extensions or public renewal discussions as of late August 2026, which would typically signal ownership commitment

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.
