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 contract is a Polymarket market titled "BNB Up or Down - October 19, 7:05PM-7:10PM ET" [1]. The source states 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 source specifies 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]. Any comparison with another BNB market should check whether it uses the same data stream, window, and comparison rule.

The listed end time is 2026-10-19T23:10:00.000Z [1]. That matches the 7:10PM ET end of the title window, but the listed end time is a contract field, not a resolution. The evidence does not show the outcome.

Reading the snapshot

The saved snapshot was observed at 2026-10-19T00:00:05.826Z and retrieved at 2026-10-19T01:18:49.799Z [1]. These are different times, and both are earlier than the listed end time. The prices below describe that observation only and should not be read as current when this text is read.

The saved 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 snapshot. The evidence does not include volume, order book depth, or trader counts, so it cannot show how much liquidity supports these prices.

The sample covers one saved market from one provider event [1]. Coverage lists one total market, one included market, and no partial sample [1]. No other platform or contract is included, so no cross-platform comparison is possible from this evidence.

What remains uncertain

The evidence does not explain why the prices were at these levels. It also does not show whether the TWAP will be at or above the starting price, since the window had not closed at the time of retrieval. The source notes that the event sample "does not establish that the providers list every possible real-world outcome" [1], though this market is a binary Up or Down contract.

Overview

This is a short-window crypto contract on the price of BNB against USD. Its title, "BNB Up or Down - October 19, 7:05PM-7:10PM ET", names a five-minute window in Eastern Time. The contract is listed on Polymarket and classified under Crypto. Its provider status at the time of retrieval was active, and its listed end time is 2026-10-19T23:10:00Z [1]. The contract's outcome depends on a time-weighted average price rather than a single trade. Under the rules, the market resolves to "Up" if the time-weighted average price of BNB over the window in the title is greater than or equal to the price at the beginning of that window. Otherwise it resolves to "Down" [1]. The two named outcomes in the saved market are Up and Down [1]. The contract is tied to one data source. The rules name Chainlink as the source, specifically its BNB/USD TWAP data stream with a 60-second interval [1]. The rules also state that the contract concerns the price in that Chainlink data stream and not prices from other sources or spot markets [1]. A reader should therefore treat the Chainlink stream, not general exchange prices, as the reference for how this contract is judged. The saved market data reports one market for this event, with no partial sampling [1]. The contract's displayed prices change over time, so any price shown in this article reflects only the moment it was recorded.

Why It Matters

The contract measures whether BNB's time-weighted average price over the five-minute window named in the title finishes at or above the price at the start of that window, as reported by the Chainlink BNB/USD TWAP data stream [1]. Because the outcome uses an average over the window rather than one trade at the end, a brief move at the close may not decide the result on its own. The rules say the contract is about that specific data stream and not about other sources or spot markets [1], so comparisons with prices elsewhere do not determine how it resolves.
