Bitcoin Up or Down - August 13, 4:00PM-8:00PM ET
Market Details
How Up/Down Markets Work
Up/Down markets let you predict whether an asset's price will be higher or lower at the end of the interval compared to the starting price.
The Price to Beat is the asset price when the interval started. If the price is above it when time runs out, "Up" wins. Below it, "Down" wins.
Prices are sourced from Polymarket's CLOB (Central Limit Order Book) and the starting price comes from the Gamma API or Chainlink oracles.

Slippage protection: rejects fills above 91.8¢. Sizing allows for the worst case: $0.26 covers the fee and that price move, and is only spent if the fill lands there.
