Underdog Fantasy has rolled out a new welcome promotion for August 2026, giving fresh users the chance to play a $5 entry and receive $50 in bonus entries when they sign up with the promo code FOXSPORTS. The offer is designed to make daily fantasy sports more approachable for newcomers and for players looking to transition into sports‑betting‑style wagering.
The launch coincides with the final week of the NFL preseason, which features 10 games—including the Commanders visiting the Ravens and the Texans taking on the Panthers—alongside a marquee MLB matchup between the Dodgers and Tigers.
Underdog’s mobile‑first platform centers on pick’em contests, best‑ball drafts and simple snake drafts, offering a clean interface that simplifies the entry‑building process. To claim the bonus, new users register an account, enter the FOXSPORTS code, deposit a minimum of $10, and play a $5 entry. Once that first entry settles, the $50 in bonus entries are credited automatically.
The promotion is available in every state where Underdog Fantasy operates, covering a broad portion of the U.S. market. Eligibility requires participants to be 21+ years old, meet the $10 deposit and $5 entry thresholds, and use the bonus entries within a 14‑day turnover window.
By emphasizing a low‑minimum, guaranteed‑value welcome bonus, Underdog aims to attract casual players who want immediate, risk‑free bonus entries without committing large amounts of capital up front.
