Understanding Kalshi Trading for Red Sox vs. Guardians

Trading on Kalshi functions exactly like trading stocks, but instead of buying shares of a company, you are buying shares of an event outcome.

For instance, if you believe Parker Messick will lead the Guardians to victory, you would purchase the "Cleveland Guardians to Win: YES" contract. If the market price is currently $0.54, you pay 54 cents for that contract. If Cleveland wins, your contract matures to $1.00, netting you a profit of 46 cents per contract. If Boston wins, the contract settles at $0.00.

Because it is a live financial marketplace, you do not have to hold your contracts until the game ends. If Cleveland takes an early 3-0 lead, the price of your "YES" contract might jump from $0.54 to $0.80. You can sell your positions early to lock in a profit, or exit a failing position to minimize potential losses.
