Kalshi is offering a “trade $10, get $10” incentive tied to Sunday’s Philadelphia 76ers–Boston Celtics matchup, the company announced on April 19, 2026.
Users who enter promo code NYPMAX and place at least $10 in trades on the platform will receive an additional $10 credited to their accounts. The promotion is listed as a limited-time offer and is valid only for the market linked to the Eastern Conference showdown.
Kalshi operates as a regulated event-trading exchange, allowing customers to buy and sell contracts based on the outcomes of real-world events, including professional basketball games. The NYPMAX code does not require an additional deposit beyond the initial $10 trade to unlock the bonus.
The Boston Celtics and Philadelphia 76ers are long-standing rivals, and their latest meeting has attracted heightened interest on betting and prediction markets. Kalshi’s promotion is designed to spur activity ahead of tip-off.
According to Kalshi’s terms, the bonus funds are applied after the qualifying trade is executed. Standard platform rules and federal trading limits continue to apply.
