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 event asks whether Bitcoin will be up or down over a short window. The source says the 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"" [1]. The title's window is 8:25AM to 8:30AM ET on October 16 [1].
The resolution source is the Chainlink BTC/USD TWAP data stream, and the source states that the market concerns "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]. A reader comparing this contract with a different Bitcoin market should check whether that market uses the same data stream, averaging method, and time window.
The listed end time is 2026-10-16T12:30:00.000Z [1]. This is the contract's listed close time, not a record of how the market has resolved. The evidence does not show a resolution outcome.
Reading the snapshot
The saved snapshot was observed at 2026-10-15T16:13:13.851Z and retrieved at 2026-10-15T18:15:25.956Z [1]. The prices below are from that observation, not from the current time.
- Up: 0.505
- Down: 0.495 [1]
These are snapshot prices, not executable quotes or verified probabilities. The gap between them is small in this snapshot. The evidence does not explain why the prices stand where they do, and it does not show trading volume, liquidity, or how many traders hold either position.
The coverage record lists one market in this event, with no partial sample [1]. The selection rule includes all saved markets for this event. The source also notes that this "does not establish that the providers list every possible real-world outcome" [1]. Because this is a binary contract with one event, there is no other outcome to compare against here.
What remains uncertain
The evidence does not include a current price, a resolution result, or any news about Bitcoin. It also does not show a comparison with other platforms or other Bitcoin contracts. Differences in wording, data source, or close time could make two similar-looking Bitcoin contracts behave differently, so a price difference between them alone would not indicate a trading opportunity.

Saved Oct 15, 2026 UTCOverview
This is a short-term binary contract on Polymarket about the price of Bitcoin during a specific five-minute window, titled "Bitcoin Up or Down - October 16, 8:25AM-8:30AM ET" [1]. The contract's listed end time is 2026-10-16T12:30:00Z [1]. The provider describes the market as active in the evidence reviewed [1]. The outcome is decided by comparing two values. The market resolves 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. Otherwise, it resolves to "Down" [1]. The contract therefore asks whether the average price across the window ends at or above where the window started, rather than whether the price at a single moment is higher. The resolution source is Chainlink's BTC/USD TWAP data stream, identified in the contract rules as a 60-second TWAP stream [1]. The rules state that only this Chainlink data stream counts, not other sources or spot markets [1]. This matters because a Bitcoin price on a different exchange or data feed could differ from the Chainlink series used for settlement. The listed end time, the window in the title, and the resolution source are separate things. The title names the window, the end time marks when the contract closes, and resolution depends on the Chainlink data for that range [1]. A date in the contract rules describes the contract terms only and does not indicate that any event is scheduled to occur.
Why It Matters
The contract measures whether Bitcoin's Chainlink BTC/USD TWAP over the stated five-minute window finishes at or above the price at the start of that window [1]. Because it uses an average rather than a single print, a brief move at the end of the window does not by itself determine the result. The rules also make Chainlink's data stream the only settlement reference, so readers should check that series rather than general market price reports when interpreting the outcome [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-15 at 16:13 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]
Frequently Asked Questions
What determines whether this market resolves Up or Down?
The market resolves Up if the Chainlink BTC/USD TWAP over the window in the title is greater than or equal to the price at the beginning of that window. Otherwise it resolves Down [1].
Which data source is used to settle the contract?
The resolution source is information from Chainlink, specifically its BTC/USD TWAP data stream with a 60-second TWAP setting [1]. The rules state that other sources and spot markets are not used for this contract [1].
Why does the averaging method matter?
The contract compares a time-weighted average over the window against the starting price, not a single price at the close [1]. The result can therefore differ from a simple comparison of the start and end prices shown elsewhere.
When does the contract end?
The listed end time is 2026-10-16T12:30:00Z, which is the end of the window named in the title [1].
