The S&P 500 closed at 7,711.76 on August 28, 2026, after touching an intraday high of 7,816.70 earlier in the month, reflecting roughly 3% gains for August and 12.65% year-to-date. Strong Q2 corporate earnings—particularly from AI infrastructure and technology leaders—have driven the advance, with S&P 500 EPS growth estimates for 2026 revised upward to around 25-30% year-over-year amid heavy capex spending by hyperscalers. Recent comments from Fed Chair Warsh at Jackson Hole, reaffirming the inflation fight and raising rate-hike probabilities, prompted a modest pullback and higher Treasury yields. Traders are monitoring any final August economic releases and equity positioning as the month concludes, with elevated valuations leaving room for volatility from inflation data or policy signals.

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.
