What is Kalshi?
Kalshi is one of the best prediction market apps, which means they provide financial exchanges on sporting event contracts. Buy and sell shares on contracts of yes-or-no predictions on March Madness and other sports, like the NBA and World Baseball Classic.
Buy shares on a contract to make a trade, and sell your shares if the price changes out of your favor. Kalshi doesn't set implied probabilities on their markets. Instead, the volume you and your fellow users trade help determine the probabilities and payouts.
