This is a short-window crypto price contract on Polymarket, titled "XRP Up or Down - October 19, 9:30PM-9:35PM ET" [1]. The contract asks whether XRP's price over a five-minute window will end up at or above where it started. According to the event listing, it resolves to "Up" if the time-weighted average price (TWAP) of XRP over the window in the title is greater than or equal to the price at the beginning of that window. Otherwise it resolves to "Down" [1]. The measurement is based on a specific data feed rather than on any exchange or general market price. The listing names Chainlink's XRP/USD TWAP data stream as the resolution source and states that the market concerns the price according to that stream, not other sources or spot markets [1]. Anyone reading the contract should therefore check the Chainlink feed named in the rules, since a different price source could show a different result. The listed end time is 01:35 UTC on October 20, 2026, which corresponds to 9:35 PM ET on October 19 as written in the title [1]. Timing matters here. The contract's outcome depends on the average over the full window compared with the opening price, not on where the price sits at the final moment alone. At the time the saved market data was observed, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These are snapshot prices from the observation time. They are not executable quotes, and they should not be read as verified probabilities of an outcome.
