**Strong August CPI data released on September 11 has emerged as the dominant driver of near-term S&P 500 sentiment ahead of the September 14–18 trading week.** The print showed headline inflation accelerating on rebounding gasoline prices, pushing implied probabilities of a 25-basis-point Fed funds rate hike at the September 16 FOMC meeting to roughly 90 percent via CME FedWatch. With the index closing at 7,656.98 on September 11—up 0.86 percent that session but still about 2 percent below its August 13 record of 7,816.70—traders are weighing the tension between persistent price pressures and resilient corporate earnings, particularly in AI-related names. The benchmark trades at approximately 19 times forward earnings amid the pullback, while Treasury yields have risen in response to the hawkish repricing. Key upcoming releases, including August retail sales on September 16 and the FOMC decision itself, will likely set the tone for volatility and directional moves during the week.

This market will resolve to "Yes" if, at any point after market creation and during the week of September 14 2026, any 1-minute candle for S&P 500 (SPY) has a final "High" or "Low" price equal to or beyond (above for ↑ High Prices, below for ↓ Low Prices) the listed price. Otherwise, this market will resolve to "No".
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.**Strong August CPI data released on September 11 has emerged as the dominant driver of near-term S&P 500 sentiment ahead of the September 14–18 trading week.** The print showed headline inflation accelerating on rebounding gasoline prices, pushing implied probabilities of a 25-basis-point Fed funds rate hike at the September 16 FOMC meeting to roughly 90 percent via CME FedWatch.
