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.

The Federal Reserve’s September 25-basis-point rate hike to the 3.75-4.00% target range, responding to persistent inflation and robust retail sales, has lifted Treasury yields above 5% and introduced volatility, tempering some upside forecasts. Analyst year-end 2026 targets range from 7,400 to 8,100, reflecting earnings momentum offset by elevated oil prices near $100 and geopolitical risks. Q3 earnings releases and upcoming economic data will likely drive near-term price action and implied probabilities.
