About This Event
This market will resolve to "Up" if the time-weighted average price (TWAP) of XRP, generated by Chainlink, of the time range specified in the title is greater than or equal to the price at the beginning of that range. Otherwise, it will resolve to "Down". The resolution source for this market is information from Chainlink, specifically the XRP/USD TWAP data stream available at https://data.chain.link/streams/xrp-usd-twap-60s-streams. Please note that this market is about the price according to the TWAP Chainlink data stream for the asset pair XRP/USD, not according to any other sources or spot markets.

What the contract measures
This Polymarket event, titled "XRP Up or Down - October 28, 12:40AM-12:45AM ET" [1], asks whether a short price window will end higher or lower than it began. According to the provider's rules, the market "will resolve to "Up" if the time-weighted average price (TWAP) of XRP, generated by Chainlink, of the time range specified in the title is greater than or equal to the price at the beginning of that range" [1]. Otherwise it resolves "Down" [1].
The resolution source is the Chainlink XRP/USD TWAP data stream, and the rules state that the market concerns "the price according to the TWAP Chainlink data stream for the asset pair XRP/USD, not according to any other sources or spot markets" [1]. A price on a different exchange or index is therefore not the reference for this contract, even if it looks similar.
The listed end time is 2026-10-28T04:45:00.000Z [1]. That is the contract's close time, not a confirmed resolution time. The supplied evidence does not show when or how the market was settled.
Reading the snapshot
The provider observed the market at 2026-10-27T09:00:05.939Z, and the source was retrieved at 2026-10-27T09:06:38.657Z [1]. The status recorded at observation was "active" [1]. These timestamps describe a past snapshot, not live trading.
The saved prices were Up at 0.505 and Down at 0.495 [1]. Read as snapshot prices, these put the Up outcome slightly above even, but the gap is only 0.010. These are not executable quotes, and the evidence does not confirm them as probabilities. The evidence also contains no volume or trader count, so it says nothing about how deep the market is or how many participants hold each side.
The sample covers one market from one platform. The coverage record shows one total market, one included, and no partial sample [1]. Because only Polymarket appears here, no comparison with other platforms is possible. Averaging or ranking across other providers' contracts would combine different rules and close times, so this snapshot should be read on its own terms.
What remains uncertain
The evidence does not explain why the Up and Down prices sit where they do, and it does not report any news or event behind them. It also does not show what XRP's price was at the start of the window or how it moved during the window, so the outcome cannot be determined from the supplied material. The sample warning notes that the included markets do not establish that the provider lists every possible outcome [1]. Finally, the observation is from 2026-10-27 and does not reflect prices at the time of reading.

Saved Oct 27, 2026 UTCOverview
This is a short-window price contract on XRP, listed on Polymarket under the title "XRP Up or Down - October 28, 12:40AM-12:45AM ET" [1]. The contract is in the crypto category and covers one five-minute window. Its outcomes are "Up" and "Down" [1]. The rule is based on an average price rather than a single moment. According to the rules, the market 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 start of that window. Otherwise it resolves to "Down" [1]. The price is measured over the whole window, so a brief move near the start or end affects the result less than a sustained move would. The resolution source is Chainlink's XRP/USD TWAP data stream [1]. The rules state that only this Chainlink data stream counts, not other sources or spot markets [1]. A trader therefore needs to understand the Chainlink feed, not just the price on a particular exchange. The event record shows a provider status of active at the time it was observed, with a listed end time of 2026-10-28T04:45:00Z [1]. This is the contract's scheduled closing time under its listing. It is not a report of what happened in that window, and no outcome has been recorded in the supplied evidence.
Why It Matters
The contract measures whether XRP's time-weighted average price over a five-minute window finishes at or above its starting price, as reported by Chainlink's XRP/USD TWAP data stream [1]. Because it uses an average over the window and a single named data feed, the result depends on how that feed behaves during those five minutes. Prices for the two outcomes show how the market valued each side at the time of the snapshot, but they are not executable quotes or verified probabilities.

Frequently Asked Questions
What determines whether this market resolves Up or Down?
It resolves Up if the TWAP of XRP over the stated window is greater than or equal to the price at the beginning of that window, and Down otherwise [1].
Which price source is used?
The rules specify Chainlink's XRP/USD TWAP data stream. The market is about that feed and not any other sources or spot markets [1].
When is the market scheduled to close?
The listed end time is 2026-10-28T04:45:00Z, and the title gives the window as 12:40AM to 12:45AM ET [1]. The end time is a contract rule, not a report that the window has already been resolved.
