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 short-window crypto contract on the price of BNB. Under the resolution rules, the 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"" [1]. The stated resolution source is the BNB/USD TWAP data stream, and the rules specify that 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]. Readers should therefore compare this contract only with other contracts that use the same resolution wording and source.
Reading the snapshot
The saved record lists two outcomes: "Up" at 0.505 and "Down" at 0.495 [1]. These prices were observed at 2026-10-27T00:00:05.999Z and retrieved at 2026-10-27T01:11:34.523Z [1]. They are snapshot prices, not executable quotes or verified probabilities. The record covers one market within one event, and it is not flagged as a partial sample [1]. The sample warning adds that it "does not establish that the providers list every possible real-world outcome" [1]. For a binary Up or Down contract, the two listed outcomes are the saved set, but the caveat still limits what the record proves.
The title gives the window in ET, "4:30PM-4:45PM ET," while the listed end time is 2026-10-27T20:45:00.000Z [1]. Readers should check the time-zone relationship themselves when matching the window to the close. The provider status was recorded as active at retrieval [1].
The evidence contains no volume or trader counts, so it says nothing about liquidity or how many participants hold either side.
What remains uncertain
The supplied evidence does not explain why the two prices sit where they do. It does not show a current price, an executable trade, or the final outcome. Because only one provider event is included, there is no basis for cross-platform comparison, and a price difference between differently worded contracts would not by itself indicate an opportunity. Resolution will depend on the Chainlink TWAP comparison described in the rules [1].

Saved Oct 27, 2026 UTCOverview
This is a short-term crypto price contract from Polymarket, titled "BNB Up or Down - October 27, 4:30PM-4:45PM ET." It asks whether the price of BNB, measured in US dollars, will finish the 4:30 PM to 4:45 PM ET window at or above where it stood at the start of that window. The contract's rules say it will resolve to "Up" if the time-weighted average price (TWAP) of BNB over that range is greater than or equal to the price at the beginning of the range, and to "Down" otherwise [1]. The measurement is a TWAP rather than a single spot price, so the result depends on the average across the window instead of the price at one moment [1]. The resolution source is Chainlink's BNB/USD TWAP data stream, which the rules identify by name [1]. The rules also state that only this Chainlink data stream counts, and not other sources or spot markets [1]. A trader reading the contract should therefore look at that specific data feed rather than at general price tickers. The listed end time is 2026-10-27T20:45:00.000Z [1]. The record was observed at 2026-10-27T00:00:05.999Z and retrieved at 2026-10-27T01:11:34.560Z, so the figures below describe that earlier snapshot. The contract's close and its eventual resolution are separate events, and the record does not show a resolved outcome. In the saved snapshot, the "Up" outcome was priced at 0.505 and the "Down" outcome at 0.495 [1]. These are snapshot prices from the provider, not executable quotes or verified probabilities. The saved sample covers one market for this event, and the record indicates that all saved markets for the event are included. That does not establish that the provider lists every possible outcome for the window.
Why It Matters
The contract measures the direction of BNB's price over a 15-minute window, using a time-weighted average from a named data feed rather than a single trade or spot quote [1]. Because the rules fix the reference price at the start of the range and compare it against the TWAP across the range, the contract turns on the path of the average price during the window, not only on the endpoints [1]. Its rules also limit the outcome to one data source, which sets a clear basis for how the result is determined [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-27 at 00:00 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. [1]
Frequently Asked Questions
What price does the contract compare?
It compares the time-weighted average price of BNB over the 4:30 PM to 4:45 PM ET window against the price at the beginning of that window, using the Chainlink BNB/USD TWAP data stream [1].
Which data source decides the outcome?
The rules say the resolution source is information from Chainlink, specifically the BNB/USD TWAP data stream, and that other sources or spot markets do not count [1].
When does the market end?
The listed end time is 2026-10-27T20:45:00.000Z [1]. This is the scheduled close recorded in the contract data, not a record of how the market resolved.
Do the prices show the chance of an "Up" result?
The saved prices were 0.505 for "Up" and 0.495 for "Down" [1]. These are snapshot prices from the provider and are not executable quotes or verified probabilities.
