Tracks the leading outcome in a winner-take-all prediction market set with 5 outcomes.

Why this matters:
Christopher Luxon, New Zealand's current Prime Minister, is priced at 44% to remain in the position at the next change of leadership, while former PM Chris Hipkins is next at 31%. This probability reflects market expectations about whether Luxon will complete his current term or lose office sooner through either electoral defeat or internal party pressure. The market is pricing in meaningful uncertainty: the second-place outcome carries 30% combined probability, suggesting traders view his position as favorable but not dominant. Key factors affecting this price include domestic economic conditions, polling trends ahead of New Zealand's 2026 general election, and internal Labour Party dynamics around Hipkins. The election itself, scheduled for late 2026, represents the primary near-term catalyst that would materially shift these probabilities. Market activity has been minimal recently across most contracts, suggesting limited new information flowing into pricing.

Key factors:
- Christopher Luxon held the premiership as of May 2026, creating incumbency advantage but also exposure to economic or political shocks before the scheduled general election
- Chris Hipkins, the main alternative, represents Labour's last elected PM; his 31% price reflects viability as a potential comeback candidate if sentiment shifts
- New Zealand's 2026 general election represents the scheduled resolution event; outcomes could either return Luxon to office or elevate an alternative candidate
- Minimal 24-hour trading volume on most contracts indicates low recent conviction or new information entering the market
- The 44% probability for the leading outcome, combined with 26% distributed among three minor candidates, suggests the market views both Luxon retention and a transition as plausible scenarios

## 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.
