Snapshot observed 2026-10-18T00:00:06.191Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

This is a single binary market on whether the one-hour BTC/USDT candle beginning at the time in the title closes at or above its open. The rules state that the 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" [1]. Otherwise it resolves to "Down" [1].

The resolution source is Binance, specifically the BTC/USDT pair. The rules say the market "is about the price according to Binance BTC/USDT, not according to other exchanges or trading pairs" [1]. A reader comparing this contract with a Bitcoin price market on another platform, or with a different trading pair, should expect the outcomes to be defined differently.

The title gives the time in ET, but the listed end time is 2026-10-18T02:00:00.000Z [1]. Readers should convert between these time zones carefully before comparing timing.

Reading the snapshot

The saved snapshot was observed at 2026-10-18T00:00:06.191Z and retrieved at 2026-10-18T00:29:45.460Z [1]. The provider status at retrieval was listed as active [1]. These are two different times: the observation time is when the provider data was captured, and the retrieval time is when this record was fetched. Neither is the contract's closing time, and neither shows how the market stands now.

The saved prices were Up at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes, and they should not be read as verified probabilities. The gap between them is 0.01 at the observation time. The record does not include volume, order book depth, or trader counts, so it says nothing about liquidity or how many participants hold each view.

The sample covers one market, with 1 of 1 saved markets included and no partial sample flag [1]. The saved event contains only this market, so there is no other outcome in this record to compare against. The record also notes that the sample does not establish that the provider lists every possible outcome [1].

What remains uncertain

This snapshot does not show the market's price after 00:00:06 UTC on October 18, 2026. It also does not show the final result, the Binance open or close values for the candle, or whether the candle has finalized. The rules say the close and open "will be used once the data for that candle is finalized" [1], and the record does not confirm that this has occurred.

The record does not explain why the prices are where they are. Any reason for a price move would be speculation based on this evidence.
