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 16, 4:40AM-4:45AM ET" [1]. The rules say 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, and the rules state 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].
The listed end time is 2026-10-16T08:45:00.000Z [1]. That is the close time for the contract, not a record of how the contract resolved. The supplied evidence does not show a resolution outcome.
Reading the snapshot
The provider observed this market at 2026-10-15T16:13:13.851Z, and the source was retrieved at 2026-10-15T18:58:07.190Z [1]. These are past times relative to the retrieval time. The saved quotes are "Up" at 0.505 and "Down" at 0.495, and the status is active [1].
These are snapshot prices, not executable quotes or verified probabilities. The gap between the two outcomes is 0.010 in this snapshot. Because the two prices come from one saved observation, they do not show how the market has moved since then. The evidence also does not explain what drove the prices.
The sample covers one market from one provider event. The coverage record reports one total market, one included market, and no partial sample [1]. The provider notes that the saved markets "does not establish that the providers list every possible real-world outcome" [1]. Here, the only outcomes are the two binary sides shown.
Volume data is not supplied, so this snapshot cannot be used to judge liquidity.
What remains uncertain
The evidence does not include a current price, a resolution result, or any other market for the same window. It also does not compare this contract with contracts on other platforms, so no cross-platform comparison is possible from these sources. Any difference in wording, window, or close time between contracts would need its own rules to be checked before comparing prices.

Saved Oct 15, 2026 UTCOverview
This contract is a short-window Bitcoin price market titled "Bitcoin Up or Down - October 16, 4:40AM-4:45AM ET" in the crypto category on Polymarket [1]. It asks whether Bitcoin's price moves up or down over one five-minute window, and it has two outcomes, "Up" and "Down" [1]. The resolution rule is specific. 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 price used is not a single trade or a spot exchange quote. It is the Chainlink BTC/USD TWAP data stream at the URL listed in the source, and the source states that the market is about the price according to that stream and not according to any other sources or spot markets [1]. The listed end time is 2026-10-16T08:45:00.000Z, which is the close point of the contract [1]. The title gives the window in Eastern Time, while the listed end time is expressed in UTC [1]. The end time is a contract rule. It is not evidence of when a result has been determined or announced.
Why It Matters
The contract measures the direction of Bitcoin's price across one short, defined window, using the Chainlink BTC/USD TWAP data stream as the reference [1]. Because the rule compares the average price over the window with the price at the window's start, the outcome depends on that averaged series rather than on the final price alone [1]. Traders reading the contract should therefore check the data stream named in the rules, not general Bitcoin price headlines or other exchanges, since the source explicitly excludes other sources and spot markets [1]. The saved event contains one market, and that market has the two outcomes described above [1]. This is a single contract rather than a field of several outcomes, so it does not show how other windows or other assets are priced.
