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 the window titled "Bitcoin Up or Down - October 20, 12:00AM-12:15AM ET" [1]. According to the saved rules, it resolves to "Up" if the time-weighted average price (TWAP) of Bitcoin, generated by Chainlink, 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 resolution source is the Chainlink BTC/USD TWAP data stream, and the rules 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]. A reader comparing this with a contract on another platform should check whether that contract uses the same data source, averaging method, and time window, because differences in wording change what is being priced.
The listed end time is 2026-10-20T04:15:00.000Z [1]. The title uses ET, while the listed end time is in UTC, so readers should convert carefully. The end time marks when the contract closes. It is not evidence of how the window resolved, and this snapshot does not show a resolution.
Reading the snapshot
The provider observed the market at 2026-10-19T06:00:06.076Z, and the record was retrieved at 2026-10-19T06:18:16.076Z [1]. These are past snapshot times, not live data. The saved prices are 0.505 for "Up" and 0.495 for "Down" [1]. These are snapshots, not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record, but that does not make them a confirmed forecast.
The coverage record lists one market in the saved event, and no partial sample is flagged [1]. Since this is a single binary contract, there is no other outcome in this snapshot to compare across platforms. The record also contains no volume figure, so nothing here speaks to liquidity or to how many traders are active.
What remains uncertain
The saved evidence does not explain why the prices sit where they do, and this summary does not infer a cause. It also does not show any news, any equivalent contract on another platform, or the outcome of the 12:00 to 12:15 AM ET interval. Prices that differ between contracts with different rules are not an arbitrage signal. Readers who need current conditions should consult the provider directly, since this record reflects only the saved observation time.

Saved Oct 19, 2026 UTCOverview
This PredictPedia entry covers a short-term Bitcoin price contract titled "Bitcoin Up or Down - October 20, 12:00AM-12:15AM ET." It is listed in the crypto category on Polymarket and has two outcomes, Up and Down [1]. The contract is about a fifteen-minute window, and its title states the window's time range [1]. The resolution rule compares two prices. The market resolves to Up if the time-weighted average price (TWAP) of Bitcoin over the window is greater than or equal to the price at the beginning of that window. Otherwise it resolves to Down [1]. The contract therefore asks whether the average price during the window holds at or above the starting price, rather than whether the price at the end of the window is higher. The resolution source is Chainlink's BTC/USD TWAP data stream, which the source identifies as a 60-second TWAP stream [1]. The rules say the market concerns the price in that Chainlink data stream for the BTC/USD pair, and not prices from other sources or spot markets [1]. A reader comparing this contract with a price chart from another exchange should expect that the chart may not match the resolution data. The saved event lists an end time of 2026-10-20T04:15:00.000Z [1]. In the saved snapshot, observed at 2026-10-19T06:00:06.076Z, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These figures are a single observation from that time. They are not executable quotes, and they should not be read as verified probabilities. The saved sample contains one market for this event, so there is no broader field of outcomes to compare.
Why It Matters
The contract measures whether Bitcoin's time-weighted average price over a specific fifteen-minute window is at or above the price at the start of that window, using the Chainlink BTC/USD TWAP data stream as the reference [1]. Because the rule is tied to one data stream and one time window, the outcome depends on that stream's readings and not on the broader market. The contract's listed end time and its resolution rule are the terms that determine how it settles [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-19 at 06:00 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 does the Up outcome mean for this contract?
Up resolves if the time-weighted average price of Bitcoin over the stated window, as generated by Chainlink, is greater than or equal to the price at the beginning of that window [1].
What does the Down outcome mean?
Down is the result if the Chainlink TWAP over the window is below the price at the beginning of the window [1].
Which price feed decides the result?
The rules name Chainlink's BTC/USD TWAP data stream as the resolution source and state that other sources or spot markets do not determine the outcome [1].
Do the listed prices show the chance that Bitcoin rises?
The saved prices are a snapshot of Up at 0.505 and Down at 0.495 at one observation time [1]. They are not executable quotes or verified probabilities.
