This is a short-window price contract on XRP, listed on Polymarket under the title "XRP Up or Down - October 20, 1:45AM-1:50AM ET" [1]. It asks whether XRP's price will move up or down over a five-minute window. The contract resolves to "Up" if the time-weighted average price (TWAP) of XRP over the time range in the title is greater than or equal to the price at the beginning of that range. Otherwise, it resolves to "Down" [1]. The price measure is specific. The resolution source is Chainlink's XRP/USD TWAP data stream, not spot prices from exchanges or other sources. The rules state that the market is about the price according to that Chainlink data stream for the XRP/USD pair, and not according to any other sources or spot markets [1]. A contract like this therefore depends on how one particular data feed averages the price, which can differ from the price shown on a trading screen at a given moment. The listed end time is 2026-10-20T05:50:00.000Z [1]. That is the time the contract is set to close, which is distinct from the time it resolves. The source excerpt describes the resolution rule but does not state a separate resolution timestamp, so the end time should not be read as confirmation of an outcome. At the time of the snapshot, the listing showed two outcomes. "Up" was priced at 0.505 and "Down" at 0.495 [1]. These are snapshot values from the provider's data, not executable quotes or measured probabilities. The market is listed with an active status in the provider data [1].
