Tracks the leading outcome in a winner-take-all prediction market set with 6 outcomes.

Why this matters:
Markets are pricing a 97% probability that the national debt will reach $40 trillion before the Trump Administration ends, compared to 78% for $45 trillion and 33% for $50 trillion. The national debt currently stands near $36 trillion and grows through a combination of mandatory spending, discretionary appropriations, and interest payments on existing debt. The probability reflects expectations about fiscal deficits over the remaining administration period. Primary drivers include the trajectory of federal spending relative to revenue, economic growth rates affecting tax collections, and interest rates determining debt service costs. Resolution depends on Treasury Department debt-level data releases and Congressional appropriations decisions in the remaining months of the term.

Key factors:
- Current national debt is approximately $36 trillion; reaching $40 trillion requires approximately $4 trillion in additional borrowing
- Annual federal deficits typically range from $1-2 trillion; cumulative deficits through administration end determine debt trajectory
- Interest rates and economic growth rates directly affect both debt service costs and revenue collections, creating uncertainty in deficit projections
- Remaining time in administration limits the window for debt accumulation; shorter timeframe makes higher thresholds ($45T, $50T) progressively less likely
- Monthly Treasury debt data releases provide concrete measurements to track progress toward the $40 trillion threshold

## 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.
