Kalshi is a company that describes itself as a prediction market, but many consider it a gambling site. It allows millions of people to place trades, or bets, on events and makes money by charging a transaction fee. The company has been banned in Nevada, a decision it disputes.

Kalshi is currently facing lawsuits from four states. Despite this, the company has achieved significant success and was recently valued at $22 billion by investors.
