⚖️

Price = Probability

A contract at $0.67 means the market thinks there's a 67% chance the event happens.

🔄

Exit any time

You don't have to wait for resolution. If your contract moves in your favour, sell early and lock in profit.

🎯

Edge, not opinion

Profitable traders ask "is the market's probability wrong?" — not "what will happen?"

📊

Arbitrage exists

The same event can be priced differently on Kalshi vs Polymarket. That gap is a potential risk-free profit.
