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 is titled "Bitcoin Up or Down - October 27, 11:25AM-11:30AM ET" [1]. 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 from Chainlink, and the source 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]. Read the rule carefully: the test compares an average over the window with the starting price, not the price at the end of the window.
Reading the snapshot
The saved snapshot was observed at 2026-10-26T21:00:06Z and retrieved at 2026-10-26T22:01:40Z [1]. It shows a provider status of active and a listed end time of 2026-10-27T15:30:00Z [1]. These times describe when the data was captured, not the current state of the market.
The snapshot records Up at 0.505 and Down at 0.495 [1]. These are prices from one saved observation. They are not executable quotes, and they are not verified probabilities. The gap between them is small, and the snapshot does not explain why the prices were where they were.
The sample covers one market from one provider event, and it is complete for that event: the coverage record lists one total market, one included, and no partial sample [1]. The source does not establish that the provider lists every possible outcome for this window, but for a binary Up or Down contract that limitation is minor. No other platform appears in the evidence, so no cross-platform comparison is possible.
What remains uncertain
The evidence does not include any trading volume, liquidity depth, or number of participants, so it cannot indicate how easily a position could be entered or exited. The evidence also does not show the Chainlink TWAP values for the window, so the eventual outcome cannot be determined from this record. A reader comparing this contract with another should first check that the wording, data source, and listed close time match, since a different window or reference feed would settle on a different question.

Saved Oct 26, 2026 UTCOverview
This PredictPedia entry covers a short-term Bitcoin price contract listed on Polymarket under the title "Bitcoin Up or Down - October 27, 11:25AM-11:30AM ET" [1]. The provider's saved event record shows one market in this event, with two outcomes, Up and Down [1]. The provider record describes the status as active at the time it was observed, and it lists an end time of 2026-10-27T15:30:00.000Z [1]. That observation is a past snapshot. It does not establish that the market is still open or that it has resolved. The contract's rules define its outcome by a price measurement rather than by a spot quote. According to the provider's excerpt, the market 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 rules name the resolution source as information from Chainlink, specifically the BTC/USD TWAP data stream [1]. The rules also limit which data counts. The provider states that the market concerns the price according to the Chainlink TWAP data stream for the BTC/USD pair, and not according to any other sources or spot markets [1]. A trader reading the Bitcoin price on an exchange or aggregator therefore would not be reading the measure that settles this contract, unless that figure matched the Chainlink stream.
Why It Matters
The contract measures whether Bitcoin's 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 the rules specify this exact data stream and exclude other sources and spot markets, the outcome depends on that measurement and not on general market sentiment about Bitcoin [1]. Understanding the settlement method is necessary before interpreting any displayed price for the contract. The displayed price is a snapshot from the provider's record and does not show what a trader could execute at that moment, and it is not a verified probability of the outcome.
