Polymarket's BTC Up/Down markets price a simple binary question — will BTC be higher or lower at expiry — across five timeframes: 5m, 15m, 1h, 4h, and 24h. Because payouts are $1 per winning share, the share price is the market's implied probability.
Browse live BTC markets under crypto markets, or pull historical BTC Up/Down orderbook and trade data at 5m–24h resolution on the Pro plan.
