Tracks the leading outcome in a winner-take-all prediction market set with 10 outcomes.

Why this matters:
This market measures whether Andrew Mountbatten-Windsor will be legislatively removed from the British line of succession before January 1, 2027. At 55%, traders view passage as more likely than not but uncertain. The probability reflects the political feasibility of pursuing such legislation in the UK Parliament, balanced against the question of whether there is sufficient political will to advance it. Key dynamics include public opinion on the royal family, parliamentary priorities, and whether recent events create momentum for constitutional change. The main catalyst would be significant political developments or parliamentary action on related succession matters before year-end 2026. Current trading volume is minimal, suggesting limited market participation and potentially wider uncertainty bounds than the headline price indicates.

Key factors:
- UK Parliament has not recently prioritized legislation altering line of succession; such bills face procedural and political obstacles requiring substantial support
- Public sentiment regarding Andrew Mountbatten-Windsor and his removal specifically would need to translate into legislative action by December 31, 2026
- No scheduled parliamentary vote or formal bill introduction currently reported would indicate imminent floor consideration
- The broader pattern of legislative activity on royal prerogatives and constitutional matters suggests this remains a lower-priority reform relative to other UK governance issues
- Trading volume of $0 in 24 hours indicates minimal market conviction, suggesting the 55% price may not reflect deep analyst consensus

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
