Understanding Kalshi Trading for Astros vs Mariners

Trading on Kalshi is fundamentally different from other forms of prediction. You are not playing against a "house" but rather trading against other participants. If you believe the Mariners will win, you buy "Yes" contracts. If you think they will lose, you can either buy "No" contracts or sell "Yes" positions.

The price of a contract is a direct reflection of the market's confidence. For example, if a "Yes" contract for an Astros victory is trading at $0.46, the market believes there is a 46% chance of that happening. If your analysis suggests the probability is actually higher, you might see value in purchasing that contract. Your total return is determined by the difference between your entry price and the $1 settlement value, minus any exchange fees.
