Why did it move?

Structured · 4 factors
  1. 1

    Down 4pp over 24h

    Now 87¢; flat in the last hour.

  2. 2

    Resolution-risk signal firing

    Expires in 51h with open resolution ambiguity.

  3. 3

    Wide spread — 21.0¢

    Bid-ask spread is wide enough that intraday moves overstate any tradeable edge. Most of the headline pp move would be eaten by spread on a market order.

  4. 4

    Expiry in 51h

    Market resolves within 72 hours — the move likely reflects information about the resolution event itself rather than longer-horizon repricing. Verify the resolution source.

What to track next

  • Verify the resolution source on this page — exchange feed, official release, news consensus — before treating any move as new information.
  • Set an alert for resolution status changes — expiry is in 51 hours.

Verification actions only — never trade recommendations.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

Market Description

This market will resolve to "Yes" if the Close price for S&P 500 (SPY) on April 27, 2026 is higher than the listed price. Otherwise, this market will resolve to "No." If the two specified prices are exactly equal, this market will resolve to "No". Closing prices will be used exactly as published by Pyth, without rounding. If S&P 500 (SPY) does not trade at all during the regular session, the market will resolve 50-50. For a standard full trading session, the closing price refers to the Pyth "Close" value of the 1-minute candle corresponding to the final minute of regular trading hours on the primary exchange. If the specified day has no valid Pyth Close value for the 1-minute candle corresponding to the end of regular trading hours on the primary exchange, the market will use the last valid Pyth price achieved during the regular trading hours of the primary exchange as the effective closing price. If no valid Pyth price exists for that trading day due to a system outage, data failure, or other technical disruption, the official closing price published by the primary exchange on which the listed security trades will be used to determine the closing price for that day. If the listed date is not a trading day under the applicable trading-hours schedule as listed on Pyth, this market will resolve 50-50. In the event of a stock split, reverse stock split, or similar corporate action affecting the listed security 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 will be Pyth, specifically the "Close" values for the relevant 1-minute candle available at https://pythdata.app/explore/Equity.US.SPY%2FUSD.
