#### Discovering Events

Add a **Discover Polymarket (or Kalshi) Events** panel to browse active markets. Filter by:

* **Trending** - Most active events by volume
* **Category** - Politics, sports, crypto, entertainment, etc.
* **Watchlists** - Events you're following

Click any event to see available markets, current odds, and trading activity.

#### Trading Predictions

Add these panels to trade prediction markets:

* **Predictions Markets** - List of available outcomes for an event
* **Predictions Trade** - Place bets on specific outcomes
* **Predictions Event Chart** - Probability changes over time
* **Predictions Order Book** - Real-time order book
* **Predictions Positions** - Track your open positions and P\&L

#### How It Works

Prediction markets let you buy shares representing different outcomes. Shares pay $1 if that outcome occurs, $0 if it doesn't. Current prices reflect market consensus on probability.

Example: If "Yes" shares trade at $0.65, the market estimates a 65% chance that outcome happens.

#### Sports

Defined brings sports markets into the same interface. Browse games and events, follow live odds, and trade outcomes in USDC right alongside prediction markets. Sports coverage is still expanding as we add more leagues and event types.
