Kalshi runs hundreds of markets across sports, politics, crypto, weather and pop culture. These are some of the markets drawing the most attention today:
Prices move as news breaks and traders react, so a contract can cost more or less depending on when you trade.
Kalshi is a prediction market exchange regulated by the CFTC. Rather than betting against a house, you buy and sell contracts against other traders. Each contract is priced between $0 and $1, and that price reflects the market’s view of how likely an outcome is. If your prediction is correct, the contract settles at $1. If it is wrong, it settles at $0.
That exchange structure is the core difference from a sportsbook. There is no fixed line set by the operator, and you can sell a contract before an event ends to lock in a profit or cut a loss as prices move.
Say a contract is priced at $0.60. That implies a 60% chance of the event happening. Buy 10 shares for $6 and a correct outcome returns $10, for a $4 profit. An incorrect outcome returns nothing. Because prices shift throughout the day, the same contract can cost more or less depending on timing.
Kalshi operates under federal CFTC oversight as a designated contract market, so it is available across most of the United States. Because it is regulated at the federal level rather than state by state, it reaches some places where traditional sports betting is not yet live.
As of June 2026, the Kalshi promo code, one of the top prediction market promos, is available in 40 states plus Washington, D.C. It is not currently available in Arizona, Illinois, Massachusetts, Maryland, Michigan, Minnesota, Montana, Nevada, New Jersey and Ohio. Sports-market access is the subject of ongoing legal challenges, so this list can change.
Event contract trading involves real risk and is not suitable for everyone. Consider your own financial situation before you trade and only commit money you can afford to lose. Kalshi offers tools that include trading breaks, self-exclusion and personalized funding caps.
