Up/Down Markets
Up/Down markets are recurring short-interval crypto predictions: will the price of an asset be up or down at the end of this window? A new round opens the moment the last one closes, around the clock.
Assets and intervals
Section titled “Assets and intervals”| Interval | Assets |
|---|---|
| 5 minutes | BTC, ETH, SOL, XRP |
| 15 minutes | BTC, ETH, SOL, XRP |
| 1 hour | BTC, ETH, XRP |
| 4 hours | BTC, ETH, SOL, XRP |
| 1 day | BTC, ETH, XRP |
Find them under Crypto in Predictions, or in the Live Crypto rail on the discovery page. A timeframe switcher and round navigation let you hop between intervals and browse recent finished rounds.
How a round works
Section titled “How a round works”- The round opens and locks in its Price to beat — the asset’s price at the moment the round started, from the same Chainlink price feed Polymarket uses to resolve the market.
- You trade Up or Down while the round runs. Prices for each side move with the market’s live odds, and the page shows the live price against the price to beat, a countdown, and a live chart.
- The round closes. If the asset’s price ends above the price to beat, Up wins; below, Down wins. Resolution follows on-chain within moments, and winnings are claimable like any other market.
One-Tap trading
Section titled “One-Tap trading”Rounds measured in minutes don’t leave time for an order form. 1-Tap mode puts three preset buy amounts directly on the trading panel — $5 / $25 / $100 by default, editable — and a single tap fires a market buy on your chosen side instantly. Each preset tile shows what you’d win at the current odds.
1-Tap is on by default for Up/Down rounds (except the daily variant) and can be toggled off in the panel.
Reading the odds
Section titled “Reading the odds”Up/Down prices are probabilities like any prediction market: Up at 55¢ means the market prices a 55% chance the asset closes the window higher. Because crypto moves fast, the odds swing hard inside a round — a side that was 80¢ can be 20¢ minutes later. Early entries buy uncertainty cheap; late entries buy confidence at a premium.
