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
The contract is titled "Bitcoin Up or Down - October 20, 1:00AM-1:15AM ET" and is listed on Polymarket in the Crypto category [1]. According to the source excerpt, 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 excerpt also 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]. The listed end time is 2026-10-20T05:15:00.000Z [1].
Because the rule uses a Chainlink TWAP rather than a spot price on another venue, a reader should not assume that a price on another exchange or contract would settle the same way.
Reading the snapshot
The saved provider observation is timestamped 2026-10-19T06:00:06.076Z, and the source was retrieved at 2026-10-19T06:12:26.556Z [1]. These are snapshot times. The quoted prices were "Up" at 0.505 and "Down" at 0.495 [1]. These values are the prices recorded at that observation, not current prices, executable quotes, or verified probabilities. They also do not show how much could be bought or sold at those levels.
The saved sample includes one market from one provider event, and the coverage record reports that all markets for that event were included [1]. Volume and trader counts are not part of this evidence, so the snapshot cannot indicate liquidity or how many participants hold each side.
What remains uncertain
The evidence does not include any price movement after the observation time, so it cannot say what the prices are now. It also does not explain why the prices stand where they do. Any other contract on a different platform or with different wording or close times should be read against its own rules before comparing prices. Differences in the quoted numbers across contracts do not, by themselves, establish an arbitrage opportunity.

Saved Oct 19, 2026 UTCOverview
This PredictPedia entry covers a short-term Bitcoin price contract listed on Polymarket under the title "Bitcoin Up or Down - October 20, 1:00AM-1:15AM ET" [1]. The contract covers a 15-minute window running from 1:00 AM to 1:15 AM Eastern Time on October 20. According to the provider's rules, the market resolves to "Up" if the time-weighted average price (TWAP) of Bitcoin over that window is greater than or equal to the price at the beginning of the window. Otherwise it resolves to "Down" [1]. The rules specify which price feed counts. The resolution source is Chainlink's BTC/USD TWAP data stream, and the provider states that the market concerns the price in that Chainlink stream and not the price from any other source or spot market [1]. Anyone reading the contract should therefore check the Chainlink feed named in the rules rather than a general price chart. The listed end time is 2026-10-20T05:15:00.000Z, which corresponds to 1:15 AM Eastern Time on October 20 [1]. That end time is a contract rule. It is not a report that the window has closed or that the contract has resolved. The source material available here does not record a final resolution outcome. At the observation time of 2026-10-19T06:00:06.076Z, the provider listed the contract as active. The two outcome prices in the snapshot were 0.505 for "Up" and 0.495 for "Down" [1]. These figures are a single observed snapshot. They are not executable quotes, and they should not be read as verified probabilities.
Why It Matters
The contract measures the direction of Bitcoin's price over one 15-minute window, as recorded by a specific Chainlink TWAP data stream [1]. Because the outcome compares an average over the window with the price at the window's start, the result depends on the feed's averaged values and not on a single price printed at a single moment [1]. Users reading the contract should note that the rules tie the outcome to that feed alone, so prices or moves reported on other venues do not determine the result [1].
Snapshot context
