Tracks the leading outcome in a winner-take-all prediction market set with 9 outcomes.

Why this matters:
This contract prices the likelihood that U.S. government spending will increase by $50 billion or more before the end of 2026. The 95% probability reflects strong market confidence in near-term spending growth, driven by ongoing federal obligations, entitlement programs, and potential stimulus or infrastructure funding. The market is essentially pricing this as highly probable rather than uncertain. Key drivers of this level include baseline budget trajectory, any new appropriations bills Congress passes, and whether economic conditions trigger automatic spending increases. The main catalyst for resolution will be the end-of-year federal spending totals released by the Treasury and Office of Management and Budget, which will definitively show whether the $50 billion threshold was crossed. Secondary factors include mid-year budget reviews and any major legislative actions affecting appropriations before December 2026.

Key factors:
- Federal baseline spending trends and mandatory entitlement obligations typically increase year-over-year, making a $50 billion rise over 18 months statistically likely without major policy changes
- Congress must pass appropriations bills or continuing resolutions; failure to do so or passage of austerity measures would be needed to prevent the threshold being reached
- Treasury Department spending data releases throughout 2026 will provide intermediate signals; spending would need to decline substantially from current run rates to fall below $50 billion growth
- Economic conditions and emergency spending requests (natural disasters, defense needs) could accelerate spending beyond base forecasts
- The $50 billion threshold represents roughly 1% growth over current annual federal spending levels, making it a relatively modest hurdle

## 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.

## SF Signal
