Kalshi is running a series of sign-up promotions that offer cash-like trading bonuses for new accounts using different promo codes, according to multiple sports outlets. The offers vary by code and can include fixed bonuses (such as $25) or larger tiers, with some promotions stating totals of up to $500 for eligible trades.

Several Fox Sports promotions advertise bonuses tied to specific upcoming events or sports windows. Examples include codes such as FOXSPORTS and FOXSPORTS55, which reference bonuses for MLB markets and other scheduled sporting matchups, plus a UFC 331 trading bonus. Yahoo Sports similarly promotes new-user codes, including TSNEWS and TSN15, describing bonuses that unlock after registering and making an initial set of trades for MLB and NFL preseason or for NFL, UFC, and MLB markets. CBS Sports highlights a college football-focused code, CBSSPORTS, naming Week 0 matchups.

Across outlets, the common theme is a promotional code for new Kalshi users, with bonus amounts and eligible sports markets depending on the specific code and timing. The details differ by event, sport, and stated bonus ceiling.
