The S&P 500 extended its longest weekly winning streak since late 2023, closing the prior week at 7,473.47 and posting fresh record highs during the holiday-shortened week of May 25, 2026, with closes at 7,519.12 on May 26 and 7,563.63 on May 28 amid intraday peaks above 7,599. Tech leadership, including semiconductor gains tied to strong first-quarter AI-related earnings, combined with easing oil prices and hopes for reduced geopolitical tensions to support equity sentiment. Broader participation from small-caps and defensives emerged alongside the ongoing rally, while 10-year Treasury yields hovered near recent lows and year-ahead earnings growth expectations climbed toward 25%. Memorial Day closure on May 25 limited trading volume, leaving the index’s path sensitive to any late-week 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" 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 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.
