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.

Outcome proposed: Yes

No dispute

Final outcome: Yes

Polymarket traders price a 62% implied probability for the S&P 500 finishing the week of March 16 above 6,000, driven primarily by anticipation of the FOMC meeting on March 18-19, where steady 4.25-4.50% fed funds rate and updated dot plot projections could signal fewer 2025 rate cuts amid sticky inflation. Current SPX at 5,982 reflects recent gains from cooling PPI data, but hawkish CPI prints have capped upside, with VIX at 16 signaling moderate volatility. Key risks include Thursday's unemployment claims and Friday's Michigan sentiment; a close above 6,000 requires sustained momentum past resistance at 6,010, while historical March FOMC weeks average +0.8% SPX returns. Trader consensus weighs Fed rhetoric heavily against overbought tech momentum.
