This market will resolve according to the official closing price for S&P 500 (SPX) on the final trading day of December 2026. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. If the final trading day of the month is shortened (for example, due to a market-holiday schedule), the official closing price published for that shortened session will still be used for resolution. If no official closing price is published for that session (for example, due to a trading halt into the close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. The resolution source for this market is Yahoo Finance, specifically the S&P 500 (SPX) "Close" prices available at https://finance.yahoo.com/quote/%5EGSPC/history, published under "Historical Prices."Polymarket traders price a 26.5% implied probability for the S&P 500 closing below $6,000 by year-end 2026, edging out the $6,500-$7,000 bin at 20%, amid closely contested odds reflecting uncertainty over monetary policy and growth sustainability. March 2026 CPI surged to 3.3% year-over-year—up from 2.4% in February—exacerbating inflation fears tied to Middle East tensions and pushing Fed rate cut expectations to late 2026 or beyond, with some forecasts eyeing hikes. Despite Q1 earnings beats across tech and industrials propelling the index to records near 7,165, elevated valuations leave multiples exposed. Key swing factors include the April 28-29 FOMC decision, upcoming CPI data, and 17.4% CY2026 earnings growth delivery versus recession risks.
