About This Event
This market will resolve to "Up" if the time-weighted average price (TWAP) of BNB, 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 BNB/USD TWAP data stream available at https://data.chain.link/streams/bnb-usd-twap-60s-streams. Please note that this market is about the price according to the TWAP Chainlink data stream for the asset pair BNB/USD, not according to any other sources or spot markets.

What the contract measures
This is a single Polymarket contract on the BNB price over a five-minute window, titled "BNB Up or Down - October 20, 4:25AM-4:30AM ET" [1]. The rules state that it "will resolve to "Up" if the time-weighted average price (TWAP) of BNB, 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 BNB/USD TWAP data stream, and the rules say the market is "about the price according to the TWAP Chainlink data stream for the asset pair BNB/USD, not according to any other sources or spot markets" [1]. A reader comparing this contract with a BNB price elsewhere should note that a different source or a spot price could produce a different outcome.
The listed end time is "2026-10-20T08:30:00.000Z" [1]. This is a date in the contract's listing, not a confirmed event date, and the excerpt does not establish when or how the outcome will be published.
Reading the snapshot
The provider observation time is 2026-10-19T09:00:05.974Z, and the source was retrieved at 2026-10-19T10:00:08.355Z [1]. These are two different times, and both describe the moment the record was saved, not the present moment for a reader.
The saved quoted prices are "Up" at 0.505 and "Down" at 0.495 [1]. These are snapshot values. They are not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record, but a reader should not treat either figure as the likelihood of the outcome.
The record includes one market from one platform. The coverage data shows one total market, one included market, and no partial sample [1]. The saved status is "active" [1]. Because only this single contract appears, there is no cross-contract or cross-platform comparison to make from this snapshot.
What remains uncertain
The excerpt does not show trading volume, liquidity, the number of traders, or any reason the prices are where they are, so none of those can be inferred. The record also does not show prices after the observation time, so it cannot describe the contract's current pricing.
The sample warning notes that the saved data does not establish that providers list every possible real-world outcome [1]. Here, the saved contract is a binary Up or Down market, so no omitted outcomes are indicated in the excerpt itself.
Readers comparing this contract with a similar market on another platform should check that the windows, sources, and listed end times match before comparing prices, because differences in wording can change what each contract pays out.

Saved Oct 19, 2026 UTCOverview
This is a short-window crypto price contract on BNB against US dollars, listed on Polymarket under the title "BNB Up or Down - October 20, 4:25AM-4:30AM ET" [1]. The contract resolves to "Up" if the time-weighted average price (TWAP) of BNB 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 outcome therefore depends on how the average over the five-minute window compares with the starting price, not on where the price ends the window. The resolution source is Chainlink's BNB/USD TWAP data stream [1]. The source states that the contract concerns the price in that Chainlink data stream for the BNB/USD pair, and not any other source or spot market [1]. Traders reading the market price should therefore keep in mind that a different exchange quote for BNB could show a different picture from the one this contract settles on. The listed end time in the contract record is 2026-10-20T08:30:00.000Z [1]. The title expresses the window in Eastern Time, so the two timestamps refer to the same contract but in different formats. The record describes a contract that is active, meaning it has not yet reached its listed end time as of the retrieved record [1].
Why It Matters
The contract measures whether the Chainlink BNB/USD TWAP over the stated five-minute window is at or above the price at the start of that window [1]. Because the comparison uses an average over the window against a starting price, the contract is about the direction of BNB's average price during a short interval as recorded by one named data stream [1]. Readers should treat any displayed price for the two outcomes as a snapshot from the saved record rather than a live quote or a verified probability [1].
