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

Why this matters:
This contract estimates a 30% probability that Trump will deploy the National Guard to at least one U.S. city during 2026. The market is pricing this as an uncommon but meaningful outcome. The probability reflects uncertainty around whether Trump administration policies will prioritize National Guard deployments for domestic purposes, potentially in response to public safety concerns or civil unrest. Key drivers include the administration's approach to domestic security priorities and whether conditions emerge that officials believe warrant deployment. Resolution depends on whether any official National Guard activation for domestic purposes occurs in any U.S. city by December 31, 2026. The tight clustering of prices near 30% suggests limited consensus on likelihood.

Key factors:
- Trump administration's stated domestic security priorities and operational doctrine for National Guard deployment compared to precedent
- Occurrence and severity of any public safety incidents, civil unrest, or emergencies in U.S. cities that could trigger deployment consideration
- Legal and political constraints, including Posse Comitatus Act limitations and congressional dynamics that would affect deployment decisions
- Historical frequency of domestic National Guard deployments during comparable periods to establish baseline expectations
- Contracts currently tied between multiple outcomes at 30%, indicating market uncertainty rather than strong conviction in any single deployment outcome

## 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.
