Analysis

This prediction reflects market expectations that U.S. total public debt will exceed $38.97 trillion by May 28, 2026, with traders assigning a 91% probability to this outcome. The high confidence reflects the consistent trajectory of federal debt accumulation driven by ongoing budget deficits, which have persisted despite economic growth. Debt levels are primarily shaped by the gap between federal revenues and spending, influenced by factors like interest rates, economic growth, and legislative fiscal decisions. The resolution hinges on the Treasury Department's official public debt figures released after May 28, 2026, which typically occurs within days of month-end. Current contract spreads show traders distinguish between finer debt thresholds—91% for above $38.82T but only 52% for above $39.47T—suggesting uncertainty about the precise debt level while confidence remains high that moderate growth will occur.

  • Recent quarterly debt growth rates and Treasury issuance patterns provide the baseline for extrapolating to May 2026
  • Interest rate environment and refinancing costs affect both deficit dynamics and debt service obligations heading into the resolution date
  • Congressional fiscal actions between now and May 2026, including spending bills and revenue measures, directly determine year-over-year debt accumulation
  • Economic growth rates influence both tax revenues and demand for Treasury borrowing, creating offsetting pressure on debt levels
  • The official Treasury Department public debt figure released after May 28, 2026 serves as the single resolution mechanism that determines contract settlement

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
