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."Robust corporate earnings growth, fueled by AI-driven capital spending and productivity gains, underpins the S&P 500's 2026 advance to roughly 7,750 as of mid-August, with year-to-date gains near 14%. Trader consensus on Polymarket assigns the highest implied probability (38%) to a close above 8,000, reflecting upward revisions in EPS estimates toward $350 and Wall Street targets clustered at 7,600–8,100. Sticky inflation, elevated energy prices, and narrow market leadership introduce downside risks that temper probabilities for levels below 7,000. Upcoming economic releases and any shifts in Fed communications on rates remain key near-term catalysts that could refine these market-implied odds.
