Boom and Underdogo unveil new fantasy‑sports welcome promos

Daily‑fantasy platform Boom introduced a welcome offer for new users ahead of the World Cup round‑of‑16 match between the United States and Belgium. By entering a $5 lineup, a first‑time player receives $40 in free lineups using promo code WTOP40, subject to age and state‑eligibility requirements.

Underdog released a separate promotion for its MLB market. New registrants who deposit $5 and use promo code WTOP earn $50 in bonus entries for that night’s games on July 8, 2026. The offer also applies only to residents of legal states and requires users to meet the platform’s age limits.
