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 is titled "Bitcoin Up or Down - October 27, 8:30AM-8:45AM ET" [1]. According to the excerpt, 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 named resolution source is the BTC/USD TWAP data stream. The excerpt states that the market concerns "the price according to the TWAP Chainlink data stream," not "any other sources or spot markets" [1].

The listed end time is 2026-10-27T12:45:00.000Z [1]. This is the contract's closing time, not a resolution result. The excerpt does not report an outcome, so this snapshot cannot say which side won.

Reading the snapshot

The saved record was observed at 2026-10-26T21:00:06.062Z and retrieved at 2026-10-26T21:06:23.335Z [1]. These times describe when the record was captured. They do not establish the market's state when you read this page. The provider status was recorded as active at observation only.

At observation, the Up outcome was priced at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The excerpt includes no volume, order book depth, or trader counts, so it says nothing about liquidity or how many participants hold each view.

This sample covers one market from one provider event, and the record does not flag a partial sample [1]. Because only one contract appears, there is no other outcome in the sample to compare against, and no cross-platform comparison is possible from this evidence.

Wording matters when comparing contracts. A contract with a different time window, a different price source, or a different TWAP definition has different resolution rules, so its prices do not measure the same thing.

What remains uncertain

The evidence does not explain why the prices sit where they do. It contains no information about the current Bitcoin price, recent news, or the reasons any trader holds a position. It also contains no record of how similar contracts have resolved. Whether the Up or Down outcome occurs depends on the Chainlink TWAP data over the listed window, which the evidence does not include. Readers should check the resolution source directly and confirm the market's current status on the platform before relying on any figure here.

Overview

This PredictPedia entry covers a short-term Bitcoin price contract on Polymarket titled "Bitcoin Up or Down - October 27, 8:30AM-8:45AM ET" [1]. The contract is a binary market with two outcomes, Up and Down. Its result depends on a single measurement: the time-weighted average price (TWAP) of Bitcoin over the time range named in the title, as generated by Chainlink [1]. The contract's rules state that it resolves to "Up" if that TWAP is greater than or equal to the price at the beginning of the range. Otherwise it resolves to "Down" [1]. The resolution source is the BTC/USD TWAP data stream published by Chainlink, not any other price feed or spot exchange market [1]. The rules say explicitly that the contract concerns only the Chainlink stream for the BTC/USD pair, and not other sources or spot markets [1]. The title gives the window in Eastern time, while the listed end time in the saved provider record is 12:45 UTC on October 27, 2026 [1]. The record also shows an active status for the contract [1]. Those are the provider's listed times for the contract's close, not a statement about when the outcome has been determined. The saved record was observed at 21:00 UTC on October 26, 2026, and retrieved at 21:06 UTC the same day [1]. Any price shown with this entry reflects that earlier moment and should not be read as a live quote.

Why It Matters

The contract measures whether Bitcoin's average price over a fixed 15-minute window, as recorded in one Chainlink data stream, finishes at or above the price at the start of that window [1]. Because it uses a time-weighted average rather than a single instant, the outcome depends on the path of the TWAP across the window and not only on the value at the end. Because the rules name one data stream, the contract can differ from outcomes in other markets or on other price feeds, and the rules exclude those other sources [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-26 at 21:00 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.

Frequently Asked Questions
