This market will resolve to "Yes" if the official closing price for S&P 500 (SPX) on the final day of trading of the specified week (normally Friday) is higher than the listed price. Otherwise, this market will resolve to "No". If the final session 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, 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." Note: S&P 500 (SPX) is represented by ^GSPC on Yahoo Finance.

Trader consensus on Polymarket assigns a 42% implied probability to the S&P 500 closing above 6,000 by the end of the March 16-21 week, reflecting caution ahead of the FOMC meeting on March 18-19 amid sticky inflation signals. The index currently trades at 5,912, just 1.5% shy of the threshold, buoyed by recent tech earnings but pressured by rising 10-year Treasury yields near 4.3%. Key catalysts include Tuesday's CPI report (forecast 0.3% MoM core) and Thursday's PPI, with markets pricing a 75% chance of a 25bps Fed cut. Historical FOMC weeks see average SPX gains of 0.4%, but dot plot revisions could spark volatility, per VIX at 14.2.
