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, 2:40PM-2:45PM ET" [1]. The rules state that the 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"" [1]. The resolution source is the Chainlink BTC/USD TWAP data stream, and the rules say 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 2026-10-28T18:45:00.000Z [1]. That is the contract's closing time, not a confirmed resolution time. The evidence does not show when or how the outcome was determined.

Reading the snapshot

The saved provider observation was taken at 2026-10-27T21:00:06Z, and the source was retrieved at 2026-10-27T21:39:15Z [1]. These prices describe that observation only. They are not live quotes and may not reflect current conditions.

At the observation time, the saved prices were 0.505 for "Up" and 0.495 for "Down" [1]. These figures are snapshot prices, not executable quotes or verified probabilities. The gap between them is small, but the evidence does not explain why the prices stood where they did.

The sample covers one market from one event. The coverage record reports one total market and one included market, with no partial sample [1]. Because only this contract is present, there is no cross-platform or cross-contract comparison to make. The evidence also does not report trading volume or the number of traders, so neither can be used to judge depth or consensus.

What remains uncertain

The evidence does not show the Bitcoin price at the start of the window, the TWAP during the window, or the final outcome. It also does not show prices after the observation time. Readers should not treat the snapshot as the market's position today, since the saved data is from earlier on the same day.

The sampling note says the providers' saved markets are included, but "This does not establish that the providers list every possible real-world outcome" [1]. Since this contract is binary, its two outcomes are the only ones in the saved data, but that does not extend to any broader claim about the market.

Overview

This is a short-term binary market on Bitcoin's price direction. According to the market 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 title specifies a window of October 28, 2:40PM to 2:45PM ET [1]. The rules name the resolution source as the Chainlink BTC/USD TWAP data stream, and state that the market concerns only the price in that stream, not other sources or spot markets [1]. This means that a price difference on another exchange or market does not by itself determine the outcome of this contract. The listed end time is 2026-10-28T18:45:00.000Z [1]. That is the time written in the contract rules, and it does not show that the market has closed or been settled. At the observation time of 2026-10-27T21:00:06Z, the saved listing showed an "Up" price of 0.505 and a "Down" price of 0.495 [1]. These are snapshot prices from a single observation. They are not executable quotes, and they are not verified probabilities of the outcome. The saved sample contains only this one market for this event, and it includes all saved markets for the event, so it does not show whether any other contracts exist for the same price window.

Why It Matters

The contract measures whether Bitcoin's time-weighted average price over a five-minute window, as recorded in the Chainlink BTC/USD TWAP data stream, finishes at or above the price at the start of that window [1]. Because the rules compare the average over the window with the starting price, the contract tracks the direction of the averaged price relative to that starting point, rather than the price at a single instant [1]. The rules also limit the outcome to that one data stream, so the contract's result depends on that source specifically [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-27 at 21:00 UTC. It contains listings from Polymarket.
