Terminal

The terminal is where you browse and trade prediction markets.

​
Market feed

The terminal shows live markets from Kalshi and Polymarket in a single feed. Each market card displays:
  • Market title and category
  • Source venue (Kalshi or Polymarket)
  • Current YES/NO prices
  • Volume
  • Recent price movement
Markets are organized by category: politics, sports, crypto, finance, and entertainment.

​
Crypto price brackets

Siren has dedicated crypto price bracket markets for BTC, ETH, SOL, XRP, DOGE, BNB, and HYPE. These cards include:
  • Live token price
  • Sparkline chart showing recent price action
  • Bracket ranges (e.g., “BTC above $100k by Friday”)
  • YES/NO pricing for each bracket

​
Search and signals

Use the search bar to find specific markets by keyword. The signals feed highlights markets with unusual activity, fast price moves, or high volume spikes.

​
Trade panel

Click any market to open the trade panel. The panel shows:
  • Current YES and NO prices
  • Your position in this market (if any)
  • Amount input
  • Trade confirmation
Pick a side, enter your amount, and confirm. Siren handles routing, adaptive execution, and result reporting. For markets with a linked token, you can also swap the underlying token directly through Jupiter without leaving the terminal.
