The S&P 500 closed at 7,650.50 on September 18, 2026, up 0.17% that session but off 0.08% for the week and roughly 1.9% below its August 13 record of 7,799. Trader focus centers on the Federal Reserve’s September 16 decision to raise the target range 25 basis points to 3.75–4.00%, accompanied by a dot plot signaling further tightening and “higher for longer” guidance that has tempered risk appetite. With the index still up more than 15% year-over-year and trading near elevated valuations, the light economic calendar for the week of September 21—featuring only Richmond Fed manufacturing, new home sales, durable goods orders, and University of Michigan sentiment—offers limited near-term catalysts, leaving monetary policy expectations and any shifts in Treasury yields or equity sector rotation as the dominant drivers of price action.

Only prices achieved during the regular trading hours of the primary exchange on which the listed security trades (typically 9:30 AM – 4:00 PM ET) will be considered. Prices occurring during pre-market or after-hours trading will not qualify.
Prices will be used exactly as published by Pyth, without rounding.
In the event of a stock split, reverse stock split, or similar corporate action affecting the listed company during the listed time frame, this market will resolve based on split-adjusted prices as displayed on Pyth.
The target price will be adjusted proportionally to reflect any stock splits. Resolution will be based on the historical price data as shown on Pyth after any adjustments have been applied.
The resolution source for this market is Pyth — specifically, the S&P 500 (SPY) "High" and "Low" prices available at https://pythdata.app/explore/Equity.US.SPY%2FUSD, with the chart settings configured for 1-minute candles.
Historical 1-minute candles may be accessed by appending a Unix timestamp (seconds) to the Pyth chart URL using the "t=" parameter. Any timestamp within the listed market time frame may be used to view the relevant candle data (e.g., https://pythdata.app/explore/Equity.US.SPY%2FUSD?t=1773432000)
If the relevant Pyth data is unavailable due to a system outage, data failure, or other technical disruption that prevents verification of the required 1-minute candle data, the official daily high/low price published by the primary exchange on which the listed security trades will be used to determine whether the listed price was reached during the applicable trading session.
