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 Polymarket contract titled "XRP Up or Down - October 28, 6:15PM-6:30PM ET" [1]. The rules state that 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. Otherwise, it will resolve to "Down"" [1]. The resolution source is the Chainlink XRP/USD TWAP data stream, and the rules specify that other sources or spot markets do not determine the outcome [1].
The listed end time is 2026-10-28T22:30:00.000Z [1]. The rules describe the price window in the title, so the contract concerns the Chainlink TWAP over that window, not the price at the close of the window alone. A reader comparing this with a contract that uses a spot price, a different data stream, or a different time window should treat the two as measuring different things, even if the titles look similar.
Reading the snapshot
The saved record shows Up at 0.505 and Down at 0.495 [1]. These are snapshot values, not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record, which is consistent with a binary pair, but the snapshot does not show spreads, depth, or the trades behind either price.
The price observation time is 2026-10-28T09:00:05.951Z, while the source was retrieved at 2026-10-28T10:45:08.625Z [1]. The prices therefore describe the market at the observation time, not necessarily at the retrieval time. The saved provider status was "active" [1], but that describes the record at capture, not the market's status now. The contract's listed end time is later than both timestamps.
The sample covers one market from one provider event, with no partial sampling [1]. Because this is a single contract, no ranking or comparison with other outcomes is involved. The record does not show trading volume, so it offers no basis for judging liquidity.
What remains uncertain
The snapshot does not explain why the prices stand where they do, and this analysis does not attempt to infer that. The record does not show how many participants hold either side. It also does not show whether the price has changed since the observation time, what the XRP price was at the start of the window, or how the TWAP will evolve before the listed end time.
The saved sample warning states that the providers listing does not establish that every possible real-world outcome is included [1]. For this binary contract, the question is limited to Up or Down under the stated rule. A price difference between this contract and a differently worded contract on another platform would not by itself indicate an opportunity, since the resolution rules may differ.

Saved Oct 28, 2026 UTCOverview
This is a short-duration crypto contract on the price of XRP against the US dollar. Its title, "XRP Up or Down - October 28, 6:15PM-6:30PM ET," names a 15-minute window. The contract asks whether XRP's price over that window ends up or down relative to where the window began. According to the saved contract rules, the market resolves to "Up" if the time-weighted average price (TWAP) of XRP over the window is greater than or equal to the price at the beginning of that range, and to "Down" otherwise [1]. The measurement is not taken from any exchange or spot market. The rules specify that the resolution source is Chainlink's XRP/USD TWAP data stream, and that the market concerns the price according to that Chainlink feed rather than any other source [1]. Two dates matter here. The contract's listed end time is 2026-10-28T22:30:00.000Z [1], which is a closing time set by the contract and not a record that the outcome has been determined. The window itself is described in Eastern Time in the title [1]. Anyone reading the contract should check the rules for how the window and end time relate. The saved record shows one active contract in this event, with an "Up" price of 0.505 and a "Down" price of 0.495 [1]. These figures are a snapshot taken at the observation time shown in the record, not a live quote. They are not executable prices, and they should not be read as verified probabilities. Because the contract is about one short window, the outcome depends on how XRP's TWAP compares with its starting price, which is a different question from whether XRP's price is generally rising or falling.
Why It Matters
The contract measures a single, narrowly defined price comparison. It does not ask where XRP trades in general, but whether the Chainlink XRP/USD TWAP over the stated window is at or above the price at the window's start [1]. Because the rules tie resolution to one data stream, the result depends on that feed's data rather than on any other exchange or spot price [1]. The contract is therefore useful for understanding how short-window crypto contracts define their outcome, and the price shown for each side reflects a single saved snapshot rather than a verified forecast [1].
