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 contract covers a single five-minute window. According to the saved rules, it "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'" [1]. The rules name the Chainlink BTC/USD TWAP data stream as the resolution source and state that the 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" [1].
The listed end time is 2026-10-28T08:10:00.000Z [1]. The title's window is written in Eastern Time, so readers should compare the listed UTC end time with the title rather than with a local clock. The listed end time is when the contract closes, not the date on which it has resolved. The supplied evidence does not report a resolution outcome.
Reading the snapshot
The provider observed this market at 2026-10-27T09:00:05.939Z, and the application retrieved it at 2026-10-27T09:41:42.460Z [1]. These are two different times, and the observation is the one that matters for the prices below. The saved status is "active" [1].
The saved prices are Up at 0.505 and Down at 0.495 [1]. These are snapshot values from the observation time. They are not executable quotes, and they are not verified probabilities. The evidence does not include volume, order book depth, or trader counts, so it says nothing about how easily either side could be traded or how many participants hold each view.
The sample covers one market in one event, and the coverage record shows all markets were included [1]. Because this is the only contract in the event, there is no other outcome to compare against within this snapshot.
What remains uncertain
The evidence does not explain why the prices stand where they do. It also does not include any information about the Bitcoin price during the window, so it cannot indicate which outcome is more likely to occur. Prices from other platforms or other contract wordings should not be compared directly with this one, because differences in the window, the price source, or the close time change what each contract measures.

Saved Oct 27, 2026 UTCOverview
PredictPedia tracks a short-window Bitcoin contract from Polymarket titled "Bitcoin Up or Down - October 28, 4:05AM-4:10AM ET." The contract asks whether Bitcoin's price moves up or down over a five-minute window. Under the rules, the market resolves to "Up" if the time-weighted average price (TWAP) of Bitcoin over the stated time range is greater than or equal to the price at the beginning of that range. Otherwise, it resolves to "Down" [1]. The resolution data comes from Chainlink, not from general exchange prices. The rules name the BTC/USD TWAP data stream as the resolution source and state that the market concerns the price according to that Chainlink data stream, not any other source or spot market [1]. Anyone reading the contract should therefore check the Chainlink stream, not a headline price, to understand how the outcome is determined. The listed end time is 2026-10-28T08:10:00Z [1]. That is the close of the contract's window. It is not a statement that any particular event will occur at that time, and the rules do not describe any scheduled announcement. The contract's status as active, along with its prices, reflects the provider observation recorded in the saved data rather than the present moment. In the saved observation, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These are snapshot prices from the provider record. They are not executable quotes, and they are not verified probabilities of the outcome. The saved data also does not show trading volume or the number of participants, so those figures cannot be inferred from the price.
Why It Matters
The contract measures the direction of Bitcoin's price across a short, defined window rather than a fixed price target. It asks whether the TWAP over the window from 4:05 AM to 4:10 AM ET, as generated by the Chainlink BTC/USD TWAP data stream, is greater than or equal to the price at the start of that window [1]. Because the reference is an average over the window compared with the starting price, the outcome depends on the Chainlink data stream's values, and the rules specify that other sources do not count [1]. The prices recorded for the two outcomes show how the market valued each side at the time of the saved observation [1]. Those values describe the provider's snapshot only. They do not indicate what the outcome will be, and they do not show whether the price could be traded at that level.
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-27 at 09:00 UTC. It contains listings from Polymarket.

Frequently Asked Questions
What price source decides this contract?
The resolution source is information from Chainlink, specifically the BTC/USD TWAP data stream. The rules state that the market concerns the Chainlink data stream and not any other sources or spot markets [1].
When does the contract resolve to Up?
The contract resolves to Up if the TWAP of Bitcoin over the time range in the title is greater than or equal to the price at the beginning of that range [1].
When does the contract resolve to Down?
The contract resolves to Down if the condition for Up is not met, meaning the TWAP over the time range is below the price at the beginning of that range [1].
Do the saved prices show the chance that Bitcoin will rise?
No. The saved prices were 0.505 for Up and 0.495 for Down at the observation time [1]. These are snapshot prices from the provider record, not executable quotes or verified probabilities.
