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 on whether Bitcoin goes up or down over a fifteen-minute window, titled "Bitcoin Up or Down - October 15, 1:00PM-1:15PM ET" [1]. According to the saved rules, 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 state that the market is "not according to any other sources or spot markets" [1]. A reader should therefore compare this contract only with other contracts that use the same data stream and window.
The listed end time is 2026-10-15T17:15:00.000Z [1]. The title uses Eastern Time while the listed end time uses UTC, so readers should check the two notations against each other before comparing contracts.
Reading the snapshot
The provider observed the market at 2026-10-15T16:13:13.851Z, and the source was retrieved at 2026-10-15T18:51:33.393Z [1]. These are different times. The observation reflects prices at the time the provider recorded them, and the retrieval time reflects when this record was collected. Neither should be read as a live quote.
At observation, the saved prices were Up 0.505 and Down 0.495 [1]. These are snapshot prices, not executable quotes or verified probabilities. They show how the market was priced at that moment and nothing more. The saved data does not include volume, order depth, or trader counts, so it says nothing about liquidity or how many people took each side.
The sample covers one provider event with one market, and the coverage record marks it as complete with no partial sample [1]. Because the sample includes all saved markets for this event, there are no omitted outcomes to compare against.
What remains uncertain
The evidence does not include a resolution result, so it cannot say whether the window resolved Up or Down. The provider's status was "active" at observation [1], but the listed end time is earlier than the retrieval time, so the snapshot should not be read as describing the contract's state today.
The evidence also does not explain why prices were where they were, and a difference of 0.01 between the two outcomes is too small to support conclusions about direction. Contracts with different wording, data sources, or closing times should not be treated as equivalent or as an arbitrage opportunity merely because their prices differ.

Saved Oct 15, 2026 UTCOverview
This contract is a short-interval price market on Bitcoin, listed on Polymarket under the title "Bitcoin Up or Down - October 15, 1:00PM-1:15PM ET" [1]. It asks whether Bitcoin's price moves up or down over a fifteen-minute window. The source describes the market as resolving 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 window's listed end time is 2026-10-15T17:15:00Z, which corresponds to 1:15 PM ET on the title's date [1]. The resolution source is specified as Chainlink's BTC/USD TWAP data stream, not an exchange or general spot price [1]. The provider states that the market concerns the price according to that Chainlink data stream for the BTC/USD pair, and not according to any other sources or spot markets [1]. This matters because a trader reading the Bitcoin price on another platform could see a different number from the one used for settlement. The contract is therefore defined by the averaging method and the specific data feed, not by a headline Bitcoin price. The provider lists the market's status as active at the time of retrieval [1]. The saved record shows an observation time of 2026-10-15T16:13:13Z and a retrieval time of 2026-10-15T18:51:33Z [1]. These are different moments. The observation time is when the provider's price snapshot was taken, the retrieval time is when this record was collected, and the listed end time is when the window closes. The record does not show the final settlement outcome, so it cannot establish how the market resolved.
Why It Matters
The contract measures whether the Chainlink BTC/USD TWAP over a specific fifteen-minute window finishes at or above the value at the window's start [1]. Because it uses an average over the interval rather than a single print, the outcome depends on the path of the price during the window, not only on the endpoints. The contract's price, shown as a probability-style figure, reflects market trading on that question at a given moment. It is not a verified forecast of Bitcoin's movement, and it is not an executable quote. The rules also make clear that different data sources could give different answers, so a reader should check the named feed before comparing this contract with other Bitcoin markets [1].
