RESOLUTION RULE
Resolves on
U.S. Department of the Treasury (Daily Treasury Par Yield Curve Rates) — Daily Treasury Par Yield Curve Rate, 30-year tenor, first published value per business day
Independent check
FRED DGS30 (H.15 constant maturity, same Treasury curve)
Measurement
Daily par yield for the 30-year tenor on each business day 2026-10-01..2026-10-30; intraday values not considered
Rounding
Yields as published (two decimals)
Exceptions
The market may expire early once the threshold is met · First published value per business day governs unless the Exchange finds a material error
If the daily published par yield for the 30-year U.S. Treasury is below 5.60% on any business day between Oct 1, 2026 and Oct 30, 2026, then the market resolves to Yes.
MODEL LIMITATIONS
  • Random-walk drift assumption; no macro-release calendar effects yet
  • Contracts already decided by the published path are not forecast

Rates · Treasury yield paths — inputs: Official Daily Treasury Par Yield Curve (settlement source); EWMA volatility x bootstrapped historical daily changes. This model on the research board →
