Description

This market will resolve to "Yes" if, at any point after market creation and during the week of September 21 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.

Frequently asked questions

Currently, prediction market odds offer a unique perspective compared to traditional spot price expectations. While analysts and polls may offer forecasts for the S&P 500, this market aggregates the wisdom of the crowd, reflecting real-time monetary conviction. Discrepancies can arise due to differing methodologies and biases inherent in each approach. It’s important to remember that prediction markets incentivize accurate forecasting through financial reward, potentially leading to more informed predictions than those derived from surveys or expert opinions alone.

On Limitless, this market is priced using a continuous double auction. Traders buy and sell contracts representing different S&P 500 price levels for the week of September 21, 2026. The price of each contract fluctuates based on supply and demand, reflecting the collective belief of market participants. On Limitless, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price movements are driven by new information, changing sentiment, and strategic trading activity, creating a dynamic and responsive market for forecasting the future value of the S&P 500.

This market resolves around Sep 25, 2026, with the outcome confirmed once the S&P 500’s closing price during the week of September 21, 2026, is verifiable from credible public reporting. The market will settle based on the official closing price reported by a widely recognized financial data provider. Traders will then be paid out based on whether their chosen contract’s price level was reached, reflecting the accuracy of their predictions.

Numerous signals and events could significantly move this market. Macroeconomic data releases, such as inflation reports, GDP growth figures, and interest rate decisions by the Federal Reserve, will likely have a substantial impact. Geopolitical events, unexpected corporate earnings announcements, and major shifts in investor sentiment could also drive price fluctuations. Furthermore, any significant news related to the overall health of the US economy or global financial markets could influence trading activity and shift the probabilities reflected in this market.
