This market will resolve to "Yes" if the Treasury 30-year yield is lower than the listed value for any date between September 3, 2026 and September 30, 2026. Otherwise this market will resolve to "No". This market will resolve as soon as the Treasury 30-year yield is lower than the listed value, or once data is available for September 30, 2026. If no qualifying value is published and data is not available for September 30, 2026 by October 14, 11:59 PM ET, this market will resolve to "No". The resolution source for this market is the Department of the treasury, specifically the data listed under "Daily Treasury Par Yield Curve Rates" for the column "30 Yr" (see: https://home.treasury.gov/resource-center/data-chart-center/interest-rates/TextView?type=daily_treasury_yield_curve&field_tdr_date_value=2026).Elevated fiscal supply pressures and a rising term premium continue to anchor the 30-year Treasury yield near 5.24% as of September 4, 2026, after trading above 5% on more than 55 days this year—the most since 2006. Persistent federal deficits near 5.8% of GDP, coupled with heavy corporate issuance for AI infrastructure, have reduced demand for long-duration bonds and widened the real yield component. Recent Treasury buybacks provided only temporary relief, while the Fed under Chair Kevin Warsh has priced in roughly 70% odds of a September hike amid sticky core inflation readings. Key near-term catalysts include the September 11 CPI release and the September 15–16 FOMC meeting, which could shift market-implied odds if labor data or policy signals ease concerns over sustained higher rates.
