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 market, titled "Bitcoin Up or Down - October 26, 4:00PM-8:00PM ET," is listed on Polymarket [1]. According to the excerpt, 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. The excerpt states 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 contract comparing Bitcoin prices using a different source, window, or wording would not measure the same thing.

The listed end time is 2026-10-27T00:00:00.000Z [1]. Readers comparing this with the ET time range in the title should confirm the time zone conversion themselves. The listed end time is a close-time field, not a resolution result. The supplied evidence does not report an outcome.

Reading the snapshot

The saved observation was taken at 2026-10-25T21:00:06Z and retrieved at 2026-10-25T22:44:05Z [1]. This is a past snapshot. It does not show the market's current state, and the reported status of "active" applies only to the saved record [1].

The saved prices are Up 0.5 and Down 0.5 [1]. These are snapshot prices, not executable quotes or verified probabilities. The evidence does not include volume, depth, or trade counts, so it cannot show liquidity or how many participants are involved. It also does not explain why the two prices are equal.

The sample covers one market in one event. The coverage record reports one total market, one included market, and no partial sample [1]. The provider warning states that including all saved markets "does not establish that the providers list every possible real-world outcome" [1]. Because this is a binary Up or Down contract, the two quoted outcomes are the full set in this record, but the saved record alone does not establish that no other related contract exists.

What remains uncertain

The supplied evidence does not include the Bitcoin price at the start of the range, any later price, or the final TWAP value. It therefore does not determine whether the contract resolves Up or Down.

Current market prices, current status, and any change since the observation time are not in the evidence. The 0.5 snapshot should not be read as a forecast or as a measure of accuracy. Other Bitcoin contracts with different windows, sources, or close times should not be compared directly with this one.

Overview

This is a short-window Bitcoin contract listed on Polymarket under the title "Bitcoin Up or Down - October 26, 4:00PM-8:00PM ET" [1]. Its rules say 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 contract uses a single price source. The rules name information from Chainlink, specifically the BTC/USD TWAP data stream, as the resolution source [1]. The rules also state that the market concerns the price according to that Chainlink data stream, and not any other sources or spot markets [1]. Because of this, the outcome depends on the Chainlink series rather than on the price shown on any particular exchange. The listed end time is 2026-10-27T00:00:00.000Z, and the provider status at the time of retrieval was active [1]. The end time is the contract's closing time under its rules. It is not a separate announced event or a statement about when the outcome will be known.

Why It Matters

The contract measures whether the Chainlink BTC/USD time-weighted average price over the stated window is at or above the price at the start of that window [1]. Because it compares an average over the window with a starting price, it asks about the direction of the averaged price in that interval, not about a fixed price level [1]. The rules state that only the Chainlink data stream counts, so a different exchange price or spot market would not determine the result [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-25 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.
