Trader consensus on Polymarket overwhelmingly prices a Q1 S&P 500 decline at 93.5% implied probability (<0% return), anchored by stretched valuations—Shiller CAPE ratio exceeding 35—and fading momentum from 2024's 24% rally fueled by AI hype and rate cuts. Recent FOMC signals of policy normalization, persistent inflation above 2% target per November CPI (2.7% core), and historical mean reversion (Q1 median return of -1.2% after 20%+ prior-year gains) bolster this bearish positioning, with real capital reflecting institutional caution. Challenges include blowout Q4 earnings beats or renewed Fed dovishness ahead of January FOMC, potentially sparking 2-5% upside if growth surprises positively.

The percentage change in the S&P 500 Index (SPX) in the specified quarter will be calculated by comparing the official closing price for the S&P 500 Index (SPX) for the final trading day of the quarter to the official closing price for the S&P 500 Index (SPX) for the final trading day of the previous quarter, as reported by the Wall Street Journal. The closing price for the final trading day of the previous quarter will be subtracted from the closing price for the final trading day of the specified quarter, and then that difference will be divided by the closing price for the final trading day of the previous quarter.
Percentage changes will be rounded to two decimal places away from zero (e.g. a percentage change of 4.995% would be considered 5.00%, and a percentage change of 4.993% would be considered 4.99%)
If any relevant trading day 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 a relevant trading day (for example, due to a trading halt into the close, system issue, or other disruption), this market will use the most recent official price published by the specified resolution source as the effective closing price.
If the percentage change in the S&P 500 Index (SPX) in the first quarter of 2026 falls exactly between two listed brackets, this market will resolve to the higher bracket.
The resolution source for this market will be the Wall Street Journal, specifically the daily CLOSE prices for the S&P 500 Index (SPX) published on the S&P 500 Index (SPX) historical prices page (https://www.wsj.com/market-data/quotes/index/SPX/historical-prices).
