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 single Polymarket contract titled "Bitcoin Up or Down - October 28, 8:20AM-8:25AM ET" [1]. 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 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] A reader should therefore compare this contract against other Bitcoin markets only after checking whether each one uses the same data source, averaging method, and time window.

The title gives the window in Eastern Time, while the listed end time is recorded in UTC as 2026-10-28T12:25:00.000Z [1]. The two are the same instant in this record, but the difference in notation is worth noting when comparing contracts with different timestamp formats.

Reading the snapshot

The provider observation time is 2026-10-28T03:00:06.402Z, and the source was retrieved at 2026-10-28T04:50:54.587Z [1]. These prices describe the provider data at the observation time, not a live quote at the time you read this.

The saved prices were "Up" at 0.505 and "Down" at 0.495 [1]. Because the snapshot shows only these two outcomes for one market, it can be read as a simple comparison of the two quoted sides. These are snapshot prices, not executable quotes, and they are not verified probabilities.

The sample covers one market from one platform. The coverage record lists one total market, one included market, and no partial sample [1]. This is a complete saved record for this event only. It does not show whether other contracts on this topic exist.

What remains uncertain

The evidence does not include the trading volume, order book depth, or number of participants, so it cannot indicate how easily a position could be entered or exited. It also does not explain why the prices stand where they do.

The record shows the status as "active" at the observation time [1]. It does not confirm whether the contract is open or how it will settle. Resolution depends on the Chainlink TWAP calculation described in the rules, and the evidence does not include an outcome.

Overview

This market is a short-interval price contract on Bitcoin, titled "Bitcoin Up or Down - October 28, 8:20AM-8:25AM ET." It 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 window is therefore a five-minute period, and the outcome depends on how the average over that period compares with the starting price, not on where the price ends. The contract names Chainlink as the resolution source, specifically the BTC/USD TWAP data stream [1]. The rules state that the market concerns the price in that Chainlink data stream for the BTC/USD pair, not any other source or spot market [1]. A trader reading the price on an exchange or another data feed could therefore reach a different view than the one that settles the contract. The saved record lists an end time of 12:25 UTC, which matches the 8:25 AM ET end of the window in the title [1]. In the saved snapshot, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These figures are prices from a single observation, not executable quotes or verified probabilities, and they should not be read as a forecast of Bitcoin's direction.

Why It Matters

The contract measures whether the Chainlink BTC/USD TWAP over a specific 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, the result reflects movement across the whole interval. The contract's value is tied to that one data stream, so the rules define what counts, not general market sentiment. The saved prices were observed at 03:00 UTC on October 28, 2026, and the record was retrieved at 04:50 UTC [1]. Those times describe the snapshot only. The contract's closing time and its resolution are separate events, and the saved record does not show how the market settled.

Snapshot context

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.
