Prediction markets and combos
Polymarket's live markets, the five-minute crypto rounds, and multi-leg combos.
Markets
The Oracle lists Polymarket's open markets with their live prices; each market has its own trade page with the price chart, order book and resolution rules. Buying an outcome at price p costs p per share and pays $1 per share if it wins.
Up or down rounds
Short crypto rounds for BTC, ETH, SOL and XRP over 5 minutes, 15 minutes, 1 hour and 4 hours: will the coin close the window at or above its opening price? Rounds settle on Chainlink's price; the card charts use a public spot feed that tracks it closely.
Combos
A combo joins 2 to 50 compatible outcomes into one position that pays only if every leg wins. Polymarket prices combos by RFQ: market makers quote within 400 ms and you accept by signing within 10 seconds. Kronos reads Polymarket's public catalog of combo-enabled markets to mark which picks can combine.
How orders are placed
- Each user gets a Polymarket deposit wallet; a Kronos prediction service signs orders with Polymarket's SDK and attributes them with a builder code.
- Funding moves USDG or USDC from Robinhood Chain over Polymarket's own bridge.
- Geo-restrictions are enforced server-side and fail closed.
