Snapshot observed 2026-10-19T06:00:06.076Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

This is a single Polymarket contract titled "Bitcoin Up or Down - October 20, 1:25AM-1:30AM ET" [1]. It resolves to "Up" if the time-weighted average price (TWAP) of Bitcoin, 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 named source is the Chainlink BTC/USD TWAP data stream, and the rules state that other sources or spot markets do not govern resolution [1]. The listed end time is 2026-10-20T05:30:00.000Z [1]. This is a closing time from the contract data, not a record of how the market settled, and the evidence does not show a resolution outcome.

Reading the snapshot

The provider observed the market at 2026-10-19T06:00:06.076Z, and the record was retrieved at 2026-10-19T06:45:04.178Z [1]. Those are the only timestamps this evidence supports. At observation, the saved outcomes were Up at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record, so the saved pair reflects a two-way split at that moment. The 0.010 gap between them describes only that observation.

The sample covers one market from one provider event, and the record is not flagged as partial [1]. Because there is only one contract, there is no other market to compare, and no cross-platform comparison is possible. The evidence does not include volume, so it says nothing about liquidity or the number of traders.

What remains uncertain

The evidence does not show prices after 06:00 UTC on October 19, 2026. It also does not show whether the market has since closed or resolved, or what the final TWAP was. It does not explain why the prices stand where they do. The title uses Eastern Time, while the listed end time is given in UTC, so readers should confirm the conversion before relying on the window. Any comparison with other Bitcoin contracts should first check that the start point, window length, and data source match.
