Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
The 58% probability for the current leader reflects market expectations about who will become the next UN Secretary-General, based on limited trading activity across four contracts. The UN Secretary-General position is typically determined through negotiation among Security Council permanent members and General Assembly consensus, making outcomes difficult to predict far in advance. The current leader's elevated probability suggests traders view this candidate as having stronger diplomatic backing or fewer obstacles than alternatives. Key drivers of movement would include shifts in geopolitical alignments, statements from major powers about their preferences, or public announcements of candidacy. The next significant catalyst would be formal nomination announcements and Security Council preliminary votes, which typically occur in the months immediately preceding a scheduled leadership transition. Low overall trading volume ($23,480 in 24-hour activity) suggests limited market depth and potentially volatile price movements with concentrated positions.

Key factors:
- The current 58% probability is derived from a single leading contract; the runner-up alternative trades at only 22%, indicating meaningful market differentiation between candidates
- UN Secretary-General selection requires consensus from Security Council permanent members (US, UK, France, Russia, China), meaning vetoes by any member could eliminate leading candidates regardless of their contract price
- Trading volume is concentrated and low ($23,480 across the entire 4-contract set in 24 hours), suggesting prices may reflect thin liquidity rather than deep conviction from multiple informed traders
- The next Secretary-General term will follow the current term's 2026 end date, making formal nomination announcements and Security Council veto rounds the primary catalysts for probability shifts
- Historical UN leadership transitions involve confidential diplomatic negotiations that become public only after preliminary agreement, limiting information available for market participants to price until late-stage disclosure

## 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.
