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

The contract is titled "Bitcoin Up or Down - October 26, 10:15AM-10:30AM ET" [1]. According to the rules excerpt, the market will resolve 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. The rules state that the 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" [1]. A contract on a different platform, or one that references a different data source, would not measure the same thing, so its price should not be compared directly.

Reading the snapshot

The saved snapshot was observed at 2026-10-25T18:00:06.091Z and retrieved at 2026-10-25T18:08:16.751Z [1]. It lists Up at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. In this snapshot the two prices sum to 1.00, which reflects a single binary pair.

The sample contains one market from one provider event. Coverage is recorded as one of one market, and the sample is not marked as partial [1]. The evidence includes no volume figures, so it says nothing about liquidity or how many traders are active.

The listed end time is 2026-10-26T14:30:00.000Z, and the provider status at observation was active [1]. This snapshot does not show any price after its observation time.

What remains uncertain

Only one contract is supplied, so there is no cross-platform comparison to draw. The evidence does not explain why the prices sit where they do. Because the outcome depends on a TWAP over the window compared with the starting price, the result is not determined by a single spot print. The evidence gives no further detail on how the data stream behaves in practice.

The prices reflect the moment of observation only. The snapshot dates from October 25, 2026 in UTC, so it should not be read as the current price at any later time.

Overview

This PredictPedia entry covers a short-term Bitcoin contract listed on Polymarket under the title "Bitcoin Up or Down - October 26, 10:15AM-10:30AM ET" [1]. It belongs to the crypto category and is a binary contract with two outcomes, Up and Down [1]. The contract's resolution rule compares two values. 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 the 15 minutes shown in the title, and the listed end time is 2026-10-26T14:30:00.000Z [1]. The rule names a specific data source. The resolution source is Chainlink's BTC/USD TWAP data stream [1]. The rule states that the contract concerns the price reported by that Chainlink stream for the BTC/USD pair, and not prices from other sources or spot markets [1]. A reader therefore needs to know that the outcome is determined by that feed, not by whichever exchange price appears in other charts.

Why It Matters

The contract measures the direction of Bitcoin's price over one specific 15-minute window, as defined by a Chainlink TWAP data stream [1]. Because the comparison uses an average over the window against the price at the window's start, the result depends on the time-weighted path of the price and not only on its final value [1]. The contract's rules make the designated Chainlink feed the basis for resolution, so the feed's definition of the price controls the outcome [1].
