Bitcoin Up or Down - August 18, 3:50PM-3:55PM ET

Up/Down markets let you predict whether an asset finishes the interval higher or lower than the price it started at.

The Price to Beat is the asset price when the interval started. Polymarket settles the market by comparing it against a Chainlink time-weighted average price (TWAP), not the exact price at the moment time runs out. If that average finishes above the Price to Beat, "Up" wins; below it, "Down" wins. An exact tie resolves "Up".

Prices are sourced from Polymarket's CLOB (Central Limit Order Book) and the starting price comes from the Gamma API or Chainlink oracles.
