How to read these odds

Each price reflects the implied probability of an outcome. A lower price (further from even) means a higher payout if that side wins. Because Kalshi, Polymarket, ProphetX, BettorEdge, BetOpenly, SX Bet and more are independent markets, the same outcome can carry different prices at the same moment. Comparing them and taking the best available number is line shopping, and over many bets that edge compounds.
