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

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.
