Snapshot observed 2026-10-19T00:00:05.826Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

This is a single binary market titled "Bitcoin Up or Down - October 19, 7:45PM-8:00PM ET" [1]. The rules state that it "will resolve to "Up" if the time-weighted average price (TWAP) of Bitcoin, 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 BTC/USD TWAP data stream, and the rules say the market concerns "the price according to the TWAP Chainlink data stream for the asset pair BTC/USD, not according to any other sources or spot markets" [1].

Three times matter here and should not be confused. The provider observed the market at 2026-10-19T00:00:05.826Z, and this tool retrieved the record at 2026-10-19T00:12:40.950Z [1]. The listed end time is 2026-10-20T00:00:00.000Z, which is expressed in UTC while the title uses ET [1]. The end time is a closing time from the contract data, not a record of how the market resolved. The evidence does not include a resolution outcome.

Reading the snapshot

At observation, the saved prices were Up at 0.505 and Down at 0.495 [1]. The market was listed as active [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The evidence contains no volume or liquidity figures, so nothing here indicates depth or how many participants are involved.

The sample covers one provider event with one market, and it is complete: the coverage record reports 1 total market, 1 included, and no partial sample [1]. The sample note states that the saved markets are included but that this "does not establish that the providers list every possible real-world outcome" [1]. Because this is a binary contract, the two prices can be read side by side, but they should not be treated as evidence about the direction of Bitcoin beyond this contract's rules.

Readers comparing this with other Bitcoin contracts should check the wording, the Chainlink TWAP basis, and the listed close time first. A different reference price, averaging method, or window would make the contracts non-equivalent, so differences in their prices would not by themselves indicate an opportunity.

What remains uncertain

The evidence does not explain why the prices are where they are, and it does not show how the market has moved since observation. It does not establish the Bitcoin price at the start of the window, the TWAP value over the window, or the final resolution. Since the retrieval time is after the observation time, the prices describe the saved snapshot only and should not be read as current quotes.
