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 contract covers a 7:30 AM to 7:45 AM ET window on October 28, and the listed end time is 2026-10-28T11:45:00.000Z [1]. It resolves to "Up" if the time-weighted average price (TWAP) of Bitcoin, generated by Chainlink, over that window is greater than or equal to the price at the beginning of the window. Otherwise it resolves to "Down" [1]. The named resolution source is the BTC/USD TWAP data stream, and the provider states that the contract 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 market with a Bitcoin contract on another platform should check whether that contract uses the same source, averaging method, and time window.

Reading the snapshot

The saved prices were observed at 2026-10-27T12:00:05.938Z and retrieved at 2026-10-27T13:32:04.129Z [1]. They describe that earlier observation, not live conditions at the time of reading. The saved outcomes were Up at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The gap between them is small, and the evidence does not explain why the prices stood where they did.

The sample covers one market from one provider event. The coverage record shows one market in total, one included, and no partial sample [1]. The provider notes that the sample does not establish that all possible real-world outcomes are listed [1]. The evidence also contains no volume or trader count, so it cannot show how liquid the market was or how many participants held either view.

What remains uncertain

The evidence does not show the current price, the price at the start of the window, or the final TWAP. It also does not show the resolution result, because the window closes at the listed end time and no resolution record is supplied. The provider status recorded in the snapshot was "active" [1], but that status describes the saved observation, not the market today. Readers should check the provider page for the latest state before drawing conclusions.

Overview

This is a short-duration crypto contract from Polymarket titled "Bitcoin Up or Down - October 28, 7:30AM-7:45AM ET." [1] It asks whether Bitcoin's price will rise or fall over a 15-minute window. According to the contract rules, 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 resolution source is Chainlink. The rules name its BTC/USD TWAP data stream, which uses 60-second intervals, as the source. [1] The rules also say the market concerns the price in that Chainlink data stream for the BTC/USD pair, and not the price from any other source or spot market. [1] This means the outcome depends on that specific data feed, so a reader should check the feed named in the rules rather than a general Bitcoin price chart when following the contract. The listed end time is 2026-10-28T11:45:00.000Z. [1] The contract is described as active in the source. [1] The dated price snapshot below reflects the observation time recorded in the source and does not describe current trading.

Why It Matters

The contract measures whether the time-weighted average price of Bitcoin over a fixed 7:30 to 7:45 AM ET window ends at or above the price at the start of that window, as defined by the Chainlink BTC/USD TWAP data stream. [1] Because the comparison uses an average over the window rather than a single moment, the result depends on how the price moved across the full 15 minutes. [1] The rules also make the named data stream the only reference, so the contract's outcome is tied to that feed's data rather than to other exchanges or spot prices. [1] The recorded prices were 0.505 for "Up" and 0.495 for "Down" at the observation time. [1] These figures are snapshot prices from the provider, not executable quotes or verified probabilities, and they should not be read as a forecast of Bitcoin's direction.
