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 is a single short-window contract on XRP. It resolves to "Up" if the time-weighted average price (TWAP) of XRP, generated by Chainlink, 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 resolution source is the XRP/USD TWAP data stream from Chainlink, and the rules state that other sources or spot markets do not determine the outcome [1].
The title gives the window as "October 28, 9:30AM-9:45AM ET." The listed end time in the provider data is 2026-10-28T13:45:00.000Z [1]. That is 9:45 AM Eastern on the same date, so the listed close matches the title. The contract's rules describe the comparison against the starting price, so a reader should not assume it compares the end price against the price at the start of the window alone.
Reading the snapshot
The saved snapshot was observed at 2026-10-27T18:00:06Z and retrieved at 2026-10-27T18:49:04Z [1]. At observation, the provider status was "active" [1]. The quoted prices were 0.505 for "Up" and 0.495 for "Down" [1].
These are prices from one saved observation, not executable quotes or verified probabilities. Both outcomes sit close to each other in that snapshot. The data does not include volume, order book depth, or the number of traders, so it says nothing about liquidity or how many participants hold either view. The coverage record shows one market in this event, with no partial sample flag [1]. Because this is the only market in the saved event, there is no other outcome in this record to compare against.
What remains uncertain
The snapshot is from before the window opens, and the data supplied here does not show prices after the observation time. The evidence does not explain why the prices are where they are. It also does not show the actual XRP price path or the Chainlink TWAP value, so the resolution outcome is not known from this record.
Contracts with different windows, assets, or data sources resolve on different rules and should not be compared as if they were the same bet. A difference in price between two contracts is not, by itself, an arbitrage opportunity.

Saved Oct 27, 2026 UTCOverview
This is a short-duration crypto contract on Polymarket titled "XRP Up or Down - October 28, 9:30AM-9:45AM ET." It asks whether the price of XRP measured over a 15-minute window will finish at or above where that window started. The contract is categorized under Crypto and is listed with an end time of 2026-10-28T13:45:00.000Z [1]. The resolution rule is specific. The market resolves to "Up" if the time-weighted average price (TWAP) of XRP, generated by Chainlink, 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]. Both outcomes are therefore decided by a single average-based comparison rather than by the price at the final moment of the window. The resolution source is named in the contract rules as information from Chainlink, specifically its XRP/USD TWAP data stream with a 60-second averaging interval [1]. The rules also state that the market concerns the price according to that Chainlink data stream "and not according to any other sources or spot markets" [1]. A trader reading the contract should therefore focus on the Chainlink stream, not on prices shown on exchanges or other price pages, even when those prices look similar. The contract is one of several recurring intraday XRP contracts that share this structure, but the evidence supplied here covers only this single event. The provider lists it as active [1]. The price snapshot in this article reflects the provider observation at the time recorded in the application's dated status note and should not be read as a live quote.
Why It Matters
The contract measures whether the Chainlink XRP/USD time-weighted average price over the 9:30 to 9:45 AM ET window is greater than or equal to the price at the start of that window [1]. Because the comparison uses an average rather than a single print, a brief move at the end of the window may affect the result differently than it would under a closing-price rule. The contract's wording also limits the measured price to one data stream, so the resolution depends on that feed's values rather than on general market consensus [1]. Readers should keep the observation time, retrieval time, listed end time, and eventual resolution distinct, since the source records these as separate points [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-27 at 18:00 UTC. It contains listings from Polymarket. Market descriptions and listed closing times define the contracts; they do not establish that the real-world outcome has occurred. This article does not include a separately verified news update. [1]
