Otherwise, this market will resolve to "No." All prices recorded during regular trading hours of the primary exchange for the instrument, as reflected in Yahoo Finance's 1-minute interval ("1m") data, will be considered. Periods when the market is officially closed (e.g., holidays or maintenance breaks) will not be considered. All times referenced are local to the primary exchange on which the index trades.

The resolution source for this market is Yahoo Finance — specifically, the 1-minute interval ("1m") chart data for S&P 500 (SPX) available at https://finance.yahoo.com/quote/%5EGSPC/.The S&P 500 closed at 7,673.52 on September 8, 2026, near recent highs amid 18% year-over-year gains driven by broad earnings expansion. Elevated inflation remains the dominant factor shaping trader positioning, with July headline PCE at 3.7% and core at 3.4%, fueled by energy prices, tariffs, and AI-related capex pressures. The Federal Reserve, under Chair Kevin Warsh, has held the federal funds rate at 3.50–3.75% while signaling potential hikes, with futures pricing roughly two 25-basis-point increases by mid-2027. Solid 2–2.5% GDP growth and resilient labor data support equities, yet geopolitical tensions in the Middle East add volatility. Key near-term catalysts include the September 15–16 FOMC meeting with updated dot-plot projections, August CPI and PPI releases, and ongoing Q3 earnings reports that could clarify whether AI-driven profit momentum sustains index levels through year-end.
