The Markets tab is the main screen of Previa. It shows live prediction markets from supported platforms in a single, searchable list.

The market scanner

Each market card shows:
  • Question — The prediction being traded (e.g., “Will Bitcoin exceed $100K by March 2026?”)
  • YES / NO price — Current market odds displayed as a price bar (e.g., 72% YES / 28% NO)
  • Platform badge — Which exchange the market is on (Kalshi or Polymarket)
  • Category badge — The topic area (Politics, Crypto, Economics, etc.)
  • 24h change — How much the price has moved in the last 24 hours
  • Volume — Total trading volume
  • AI score — The Previa confidence score (0-100), if available
