The S&P 500 closed at 7,674.37 on August 21, 2026, after a 1.43% weekly decline from its August 13 record of 7,798.99, amid elevated Treasury yields and geopolitical tensions around Iran that lifted oil prices. Trader focus centers on the heavy earnings calendar, headlined by Nvidia’s August 26 report alongside Salesforce and CrowdStrike, which will test AI-driven revenue momentum and sector leadership. Key data releases include the Q2 GDP second estimate, July core PCE inflation, personal spending, and durable goods orders on August 26, plus jobless claims and consumer confidence earlier in the week. The Jackson Hole Symposium beginning August 27 will provide fresh Federal Reserve communications on monetary policy, with markets pricing in the balance between inflation trajectories and labor-market resilience. These catalysts will likely drive volatility around current index levels near the upper end of the year’s range.

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.
