The Federal Reserve’s September 16 decision to raise the federal funds target range by 25 basis points to 3.75–4.00%—its first hike in over three years—served as the dominant catalyst for S&P 500 and SPY price action during the week of September 14. Updated Summary of Economic Projections showed median PCE inflation at 3.7% for 2026 and a steeper policy path than June forecasts, reinforcing trader focus on persistent price pressures and potential further tightening. Equities responded with immediate selling, as the index fell 0.4% to 7,551.81 and SPY closed at 754.05 on September 16, extending a weekly decline of roughly 1.4%. Market-implied odds now embed a higher-for-longer stance, with Treasury yields flattening and the dollar strengthening. Traders are monitoring subsequent economic releases and any follow-through selling for resolution of weekly closing levels near current ranges.

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.The Federal Reserve’s September 16 decision to raise the federal funds target range by 25 basis points to 3.75–4.00%—its first hike in over three years—served as the dominant catalyst for S&P 500 and SPY price action during the week of September 14.
