About This Event
This market will resolve to "Up" if the time-weighted average price (TWAP) of Bitcoin, 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 BTC/USD TWAP data stream available at https://data.chain.link/streams/btc-usd-twap-60s-streams. Please note that this market is about the price according to the TWAP Chainlink data stream for the asset pair BTC/USD, not according to any other sources or spot markets.

What the contract measures
This Polymarket contract covers a short window identified in its title as "Bitcoin Up or Down - October 28, 8:15AM-8:30AM ET" [1]. According to the saved rules, it resolves to "Up" if the time-weighted average price (TWAP) of Bitcoin, 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 stated resolution source is the BTC/USD TWAP data stream, and the rules say the market is "not according to any other sources or spot markets" [1]. The listed end time is 2026-10-28T12:30:00.000Z [1].
Reading the snapshot
The saved prices are Up at 0.505 and Down at 0.495 [1]. These values come from a provider observation at 2026-10-27T15:00:05.980Z, and PredictPedia retrieved the record at 2026-10-27T17:24:43.848Z [1]. Those are historical snapshot times. They do not show current prices, and the excerpt does not say whether the market has changed since then.
The two outcome prices sum to 1.00 and differ by 0.010 [1]. Prices here are snapshots, not executable quotes, and they are not verified probabilities. The evidence does not include volume, order book depth, or trader counts, so it provides no information about liquidity or how many participants hold each view.
The sample covers one market from one provider event. Market coverage reports one total market, one included, and a partial sample flag of false [1]. This means the saved set for this event is complete. It does not establish that the provider lists every possible outcome for this window, and it supports no comparison with other platforms or contracts.
What remains uncertain
The evidence does not show the actual TWAP values, the beginning-of-window price, or the final result, so the snapshot cannot indicate how the contract will resolve. It also does not explain why prices sit where they do.
Contracts with different windows, data sources, or listed end times can have different rules even when their titles look similar. Compare the resolution wording and close times before placing this contract next to another one.

Saved Oct 27, 2026 UTCOverview
This PredictPedia entry covers a short-window Bitcoin contract listed on Polymarket under the title "Bitcoin Up or Down - October 28, 8:15AM-8:30AM ET" [1]. The contract asks whether Bitcoin's price moves up or down over a 15-minute window. The source states that the market will resolve to "Up" if the time-weighted average price (TWAP) of Bitcoin over the time range in the title is greater than or equal to the price at the beginning of that range, and to "Down" otherwise [1]. The resolution basis is specific. The source says the resolution source is information from Chainlink, specifically the BTC/USD TWAP data stream [1]. It also states that the market concerns the price according to that Chainlink TWAP data stream for the BTC/USD pair, and not according to other sources or spot markets [1]. Readers should therefore treat the contract as tied to that one data feed, not to whatever Bitcoin price appears on a given exchange or website. In the retrieved record, the market had two outcomes, "Up" and "Down" [1]. The listed end time is 2026-10-28T12:30:00.000Z [1]. That is the end time recorded in the contract data, not an announced event or a sign that anything has happened. The provider record marks the market as active [1].
Why It Matters
The contract measures the direction of Bitcoin's price across a defined 15-minute window, as represented by a Chainlink TWAP data stream [1]. Because the outcome compares the average price over the window with the price at its start, the result depends on the averaging method and the chosen feed rather than on a single moment's price [1]. A reader can use the contract's rules to see exactly what would count as "Up" or "Down," and the rules say that other sources and spot markets are not used for resolution [1]. The price shown in the market record is a snapshot of the contract's price for each outcome at the time it was observed. In the saved record, "Up" was priced at 0.505 and "Down" at 0.495 [1]. These figures are not executable quotes and should not be read as verified probabilities of the outcome.
