Tracks the leading outcome in a winner-take-all prediction market set with 2 outcomes.

Why this matters:
The Spanish People's Party (PP) is currently priced at a 73% probability of winning the next general election. This reflects market expectations based on recent polling, parliamentary dynamics, and political positioning in Spain. The primary factors supporting this level are the PP's standing in current polls and its coalition-building capacity. The market assigns meaningful but lower probabilities to the Socialist Party (17%) and other parties, suggesting uncertainty about fragmentation and government formation. The main catalyst that would move this probability significantly would be new polling data, shifts in coalition preferences among parties, or developments affecting voter sentiment. Spanish electoral calendars and any announced election dates would also trigger repricing as uncertainty narrows closer to the actual vote.

Key factors:
- Current polling shows the PP leading but potentially without an absolute majority, requiring coalition or confidence-and-supply arrangements
- The 73% probability implies roughly a 27% chance a different party or coalition wins, reflecting genuine uncertainty about non-PP outcomes
- Parliamentary fragmentation in Spain means seat totals do not automatically translate to government formation—coalition negotiations and party preferences directly affect final outcomes
- Any significant change in the Socialist Party's polling position or unexpected developments in regional politics could move probabilities substantially
- The timing of the next election call and its proximity to the current market date affects how much uncertainty remains in pricing

Contracts:
- Who will win the next Spanish general election?: People's Party — 79¢ Kalshi $0 (weight 50%)
- Who will win the next Spanish general election?: Spanish Socialist Workers' Party — 17¢ Kalshi $0 (weight 50%)

## 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.
