About This Event
This market will resolve to "Up" if the close price is greater than or equal to the open price for the BTC/USDT 1 hour candle that begins on the time and date specified in the title. Otherwise, this market will resolve to "Down". The resolution source for this market is information from Binance, specifically the BTC/USDT pair (https://www.binance.com/en/trade/BTC_USDT). The close « C » and open « O » displayed at the top of the graph for the relevant "1H" candle will be used once the data for that candle is finalized. Please note that this market is about the price according to Binance BTC/USDT, not according to other exchanges or trading pairs.

What the contract measures
This contract is a one-hour Bitcoin candle question. It resolves to "Up" if the close price is greater than or equal to the open price for the BTC/USDT 1 hour candle that begins at the time in the title, and to "Down" otherwise [1]. The resolution source is Binance, specifically the BTC/USDT pair, and the rules state that "this market is about the price according to Binance BTC/USDT, not according to other exchanges or trading pairs" [1]. The rules also say the open and close shown for the relevant "1H" candle will be used "once the data for that candle is finalized" [1].
The listed end time is 2026-10-21T06:00:00.000Z [1]. The title, however, uses the clock label "1AM ET." Readers comparing these should rely on the candle definition in the rules rather than converting the title by hand, because the two time references are written in different zones.
Reading the snapshot
The market shows "Up" at 0.5 and "Down" at 0.5 [1]. The provider observed these prices at 2026-10-19T06:00:06.076Z, and this system retrieved the source at 2026-10-19T07:51:09.543Z [1]. These are snapshot values from that observation window. They are not live quotes, executable prices, or verified probabilities, and this record does not establish what the price is now.
The sample contains one market from one provider event. Coverage shows one total market, one included market, and no partial sample [1]. The saved event includes all markets captured for it, but that does not establish that every possible real-world outcome is listed. Because only the two outcomes are shown, there is nothing to compare across other contracts in this record. The record also includes no volume or trader data, so it says nothing about liquidity or how many participants hold either side.
What remains uncertain
The evidence does not explain why the prices sit at 0.5, and it does not show any movement over time. It also does not provide any news, outcome, or information about the actual candle, since the candle has not closed within the listed end time as of the snapshot. Comparing this contract with similarly named contracts on other platforms would require their own rules, because a different pair, exchange, or close time would change what is being measured. Any difference in quoted prices across such contracts should not be treated as an opportunity without matching those terms.

Saved Oct 19, 2026 UTCOverview
This contract is a short-term binary market on the direction of Bitcoin's price over a single one-hour candle. It is titled "Bitcoin Up or Down - October 21, 1AM ET" and sits in the Crypto category on Polymarket [1]. The contract resolves to "Up" if the closing price of the BTC/USDT one-hour candle is greater than or equal to its opening price. If the close is lower than the open, it resolves to "Down" [1]. The resolution source is Binance, specifically the BTC/USDT trading pair. The open and close values shown at the top of the Binance one-hour chart for the relevant candle are used once that candle's data is finalized [1]. The rules state that the market concerns the Binance BTC/USDT price only, not prices on other exchanges or other trading pairs [1]. The listed end time is 2026-10-21 06:00 UTC, which corresponds to the 1AM ET label in the title [1]. That end time is the scheduled close of the contract's measurement window under the rules, not a record of when the market settled. The provider recorded the event as active at the time of the observation, which was 2026-10-19 06:00 UTC [1]. Any price shown in this article reflects that earlier snapshot and is not an executable quote or a verified probability.
Why It Matters
The contract measures whether Bitcoin's price, as recorded by one exchange's BTC/USDT one-hour candle, ends the hour at or above where it started [1]. Because the resolution uses the Binance pair specifically, the outcome depends on that venue's data rather than a broader market average [1]. Traders and readers can use the contract's rules to understand exactly which price comparison decides the result. Reading the market's prices requires care, since a snapshot of prices at one moment does not show how the market will settle [1].
