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 is a short-window Bitcoin contract on Polymarket with a single listed market, "Bitcoin Up or Down - October 20, 3:25AM-3:30AM ET" [1]. The rules say 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 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 2026-10-20T07:30:00.000Z [1]. The title uses Eastern Time while the listed end time is in UTC, so readers should convert the two before comparing them. The end time is when the contract closes, not the moment it resolves on any other record.
Reading the snapshot
The saved snapshot was observed at 2026-10-19T09:00:05.974Z and retrieved at 2026-10-19T09:54:09.859Z [1]. It shows "Up" at 0.505 and "Down" at 0.495 [1]. These are prices recorded at the observation time. They are not executable quotes, not verified probabilities, and they may not reflect conditions at the time you read this page. The outcomes sum to 1.000 in this snapshot, but that is a property of the recorded numbers and does not establish a tradable spread.
The coverage record lists one market for this event, with no partial sample [1]. Because this is one binary contract, there is no comparison field, no other platform, and no ranking to interpret. The snapshot does not include volume, so nothing here addresses liquidity or how many participants are active.
What remains uncertain
The evidence does not explain why the prices are where they are, and this summary does not offer a reason. It also does not show any news, recent market movement, or forecasting track record for this contract type. The source describes a provider event and does not establish outcomes beyond the two listed. Whether the market will resolve "Up" or "Down" cannot be determined from this snapshot, which was taken before the contract's listed end time.

Saved Oct 19, 2026 UTCOverview
This is a short-interval binary contract on the price of Bitcoin, listed on Polymarket under the title "Bitcoin Up or Down - October 20, 3:25AM-3:30AM ET" [1]. It has two outcomes, "Up" and "Down" [1]. The contract 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 resolution source is Chainlink. The rules name its BTC/USD TWAP data stream with a 60-second window as the reference, and state that the market concerns that Chainlink stream rather than other sources or spot markets [1]. This means the outcome depends on that specific data feed, so a different exchange price or a general spot quote would not determine resolution under these rules [1]. The listed end time is 2026-10-20T07:30:00.000Z [1]. That date and time is the contract's closing time under its rules. It is not a scheduled event or an announcement. The title's ET window and the listed UTC end time both refer to the same closing point in the contract's rules [1]. The prices in this market snapshot are Up at 0.505 and Down at 0.495 [1]. These values were observed at 2026-10-19T09:00:05.974Z and retrieved at 2026-10-19T09:54:09.884Z [1]. They are provider snapshots at the observation time. They are not executable quotes, and they are not verified probabilities of the outcome. The contract has not closed at the time of this snapshot, and the saved record shows it as active [1]. The volume figures for the market are not shown in the saved record, so no conclusions about liquidity or trader count can be drawn from it.
Why It Matters
The contract measures whether the Chainlink BTC/USD TWAP over the stated window finishes at or above the price at the start of that window [1]. Because it uses an average over the window rather than a single instant, the result depends on the feed's averaged data across the period, as the rules describe [1]. Traders following this contract are therefore tracking a defined data-feed outcome over a short interval, not a general view of Bitcoin's price. The rules also specify that other sources and spot markets do not determine the result [1].
