Kalshi is offering a $15 sign-up bonus for new users who enter WTOP15, deposit at least $1, and trade $10 on its prediction markets. The promotion lowers the upfront cost of getting started, but the bonus does not unlock until the trading threshold is met.
WTOP15 and $15
The offer gives new users a fixed $15 credit after three steps: use promo code WTOP15, make a first-time deposit of at least $1, and complete $10 in trades. That structure matters because the headline incentive is not handed out immediately; it arrives only after the account shows real activity.
Kalshi’s prediction markets are available in all 50 states, and users must be at least 18 to play. For a first-time user, that means the barrier to entry is low in cash terms, but the bonus is tied to trading volume rather than just opening an account.
World Cup on Kalshi
The promotion is tied to Friday’s World Cup predictions and can be used on any of today’s World Cup matches or on any World Cup match this week. The listed matchups include Australia vs. USA, Morocco vs. Scotland, Haiti vs. Brazil, and Paraguay vs. Turkiye.
Brazil carries an 86.2% win probability over Haiti, with the probabilities current as of June 19, 2026. That gives new users a concrete place to start, since the bonus can be applied to matches already priced by the market rather than requiring them to wait for a future slate.
Trade $10, unlock $15
The catch is simple: the article promotes a $15 bonus, but users must first put in at least $1 and then complete $10 in trades before the credit is unlocked. In practical terms, the offer favors users who intend to place trades anyway, not people looking for a no-action signup reward.
For anyone considering the promotion, the immediate checklist is straightforward: enter WTOP15, fund the account with at least $1, and place $10 in trades on Kalshi. The unresolved piece is how long WTOP15 stays available, so the value of the offer depends on acting while the promotion is live.
