Kalshi is a prediction-market exchange where users trade contracts tied to the outcomes of future events. Markets cover areas including sports, politics, economics, entertainment, weather and other real-world events.
Instead of conventional sportsbook odds, Kalshi contracts are generally priced between 1¢ and 99¢. The contract price can be viewed as the market's approximate implied probability.
For example, a Yes contract trading for 40¢ indicates that the market is pricing the outcome at approximately a 40% probability. A winning contract settles at $1, while an incorrect contract settles at $0. Kalshi is regulated by the Commodity Futures Trading Commission as a Designated Contract Market.

Kalshi has become one of the most prominent prediction-market platforms available to U.S. traders. Potential advantages include:
Kalshi is not risk-free. Contracts can settle at $0, meaning users can lose the full amount committed to an unsuccessful position. Trading fees, liquidity and bid-ask spreads can also affect the actual return. Always read the resolution criteria and contract rules before opening a position.
For someone already planning to open a Kalshi account, ATSBONUS provides a straightforward $25 bonus after $25 in qualifying trades. New users must complete at least $25 in qualifying Kalshi Predictions trades within 30 days to earn the $25 promotional credit.
Unlike some previous Kalshi promotions, this is a fixed $25 bonus rather than a randomized reward. That makes the value of the offer much easier to understand before signing up. Before claiming the offer, keep in mind:
If you already intend to trade on Kalshi, ATSBONUS effectively adds $25 in promotional trading credit after you meet the qualifying requirement. There is no reason to trade more than you otherwise intended simply to claim the bonus.
The ATS.io Kalshi promo code is ATSBONUS.
Eligible new users can enter ATSBONUS when registering and complete the promotional requirements to receive a randomized bonus credit.
The promotion is based on $25 of qualifying trading, rather than simply making a $25 deposit.
Funding your account without completing the required trading activity does not by itself satisfy the promotion.
The ATSBONUS welcome offer is intended for eligible new Kalshi users.
Kalshi currently allows eligible users to add a referral code within 72 hours of creating an account and before making their first deposit, whichever comes first.
It is safer to enter ATSBONUS during the initial registration process.
Bonus credit awarded through the promotion expires seven days after issuance.
Make sure you intend to trade before claiming the reward, as expired credits cannot normally be recovered.
The bonus credit itself cannot be withdrawn directly.
It must first be used for trading. Funds generated through qualifying trades may subsequently become withdrawable according to Kalshi's rules.
