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
The contract covers the BNB Up or Down window from 3:00AM to 3:05AM ET on October 20. The rules say 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 named resolution source is the BNB/USD TWAP data stream, and the rules state that other sources or spot markets do not determine the outcome [1].
The listed end time is 2026-10-20T07:05:00.000Z [1]. This is the contract closing time, not the time the market has resolved. The provided evidence does not show a resolution result.
Reading the snapshot
The saved provider observation is timestamped 2026-10-19T09:00:05.974Z, and the record was retrieved at 2026-10-19T09:22:05.926Z [1]. The prices below describe that earlier observation only. They do not show the market now.
The single saved outcome prices were Up at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes or verified probabilities. The two prices sum to 1.00 in this record, so the saved values describe one binary contract on one provider event.
The sample contains one Polymarket market from one event. The coverage record shows one market, all included, with no partial sample [1]. The provider's sample warning says the saved markets do not establish that every possible real-world outcome is listed [1]. This sample therefore cannot be compared with other platforms or other BNB contracts without mixing unlike windows and wording.
What remains uncertain
The evidence does not explain why the prices were where they were, and it does not show trading volume, liquidity, or the number of participants. A small gap between Up and Down in a single snapshot does not indicate how the window will close. Readers should also note that a different contract with a different window or resolution source is not directly comparable, even if its displayed price differs.

Saved Oct 19, 2026 UTCOverview
This is a short-interval price contract titled "BNB Up or Down - October 20, 3:00AM-3:05AM ET" in the crypto category, listed on Polymarket [1]. The contract's rules say it resolves to "Up" if the time-weighted average price (TWAP) of BNB, 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 resolution source is the Chainlink BNB/USD TWAP data stream, and the rules state that the market concerns only that Chainlink data stream for the BNB/USD pair, not other sources or spot markets [1]. The listed end time is 2026-10-20T07:05:00Z [1]. That date appears as a contract rule and does not show that the market has closed or been resolved. The provider status at the time of retrieval was recorded as active [1]. The outcomes are "Up" and "Down" [1]. Each outcome's price is a snapshot from the provider at the observation time shown in this article, not a live or executable quote, so it should not be read as a verified probability of the outcome.
Why It Matters
The contract measures the direction of BNB's price over a five-minute window, as defined by a specific data feed. Under its rules, the outcome depends on whether the Chainlink TWAP over that window is at or above the price at the window's start [1]. Because the TWAP averages prices across the window, the result can differ from a comparison of the start and end prices alone. The rules also limit the market to the Chainlink BNB/USD data stream, so other exchanges or spot prices do not decide the outcome [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-19 at 09:00 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 does an "Up" outcome require?
Under the rules, "Up" resolves if the Chainlink BNB/USD TWAP over the title's time range is greater than or equal to the price at the beginning of that range [1].
Which price source decides the result?
The resolution source is the Chainlink BNB/USD TWAP data stream. The rules say the market is about that feed and not any other sources or spot markets [1].
Does the listed end time mean the market has already resolved?
No. The listed end time of 2026-10-20T07:05:00Z is a date in the contract rules [1]. It is not evidence that the market has closed or that an outcome has been recorded.
Does a price difference between two similar contracts create an arbitrage opportunity?
Not on its own. Contracts with different rules, time windows or resolution sources can have different prices, and this contract's rules are limited to the Chainlink BNB/USD TWAP data stream [1].
