Kalshi offers new users $500 bonus for World Series prediction trades

Kalshi, a major online prediction-market exchange, announced a limited-time incentive for new registrants. Users who sign up, verify their details, and place a minimum of $25 in trades can input the referral code NYMAX to qualify for a bonus that may reach $500 on World Series prediction contracts. The deal is restricted to residents of specific U.S. states and territories and is available only to individuals 18 years of age or older.

Kalshi’s platform supports a variety of sports wagers, including golf, WNBA, NFL, and international soccer, in addition to MLB. Market data currently shows the Dodgers trading at roughly four times the odds of their nearest rival, the Yankees. The promotion is subject to terms and conditions, with standard cautions about the risks of event-contract trading.
