Kalshi event‑trading platform adds sports contracts and $10 new‑user promo

Kalshi is a regulated futures exchange that lets traders buy contracts whose payoff depends on the outcome of real‑world events, such as elections or economic indicators. Contracts are priced from 0 to 100, reflecting the market’s implied probability, and settle at 100 if the event occurs and 0 otherwise. This structure enables participants to monetize predictions and offers an alternative to traditional asset‑based trading.

The platform is promoting sports‑related contracts, illustrated by a market on the June 20, 2026 Athletics vs. Diamondbacks game with implied probabilities for win‑loss outcomes and total runs. New users who register with promo code “WSN”, fund the account with at least $20 and trade 100 event contracts receive a $10 bonus. The promo details and contract pricing are publicly listed on Kalshi’s site.
