A new promotion from Underdog Fantasy is giving sports fans in the United States a significant boost for Thursday Night Football. Using the exclusive promo code **FOXNEWS**, new users can deposit just $5 and instantly receive $100 in bonus cash to use on player props and pick’em contests for the Week 6 matchup between the Seattle Seahawks and the San Francisco 49ers. The offer, which runs through kickoff on October 10, 2026, is designed to attract casual bettors and seasoned fantasy players alike by lowering the barrier to entry with a high-value match.
**Contexto**
Underdog Fantasy has carved out a niche in the rapidly expanding U.S. sports gaming market by focusing on simplified pick’em games rather than traditional sportsbook odds. The platform allows users to select over/under lines on individual player statistics—such as passing yards, rushing attempts, or receptions—without needing to build a full roster. The “Play $5, Get $100” promotion is one of the most aggressive sign-up offers currently available in the legal sports gaming space, reflecting the intense competition among operators like DraftKings, FanDuel, and PrizePicks for market share.
The Seattle Seahawks enter the game with a 3-2 record, led by quarterback Geno Smith, who has thrown for over 1,400 yards through five games. The San Francisco 49ers, despite a 2-3 start, remain a statistical powerhouse on defense, ranking in the top five in yards allowed per game. The NFC West rivalry adds an extra layer of intensity, as both teams are fighting for divisional positioning early in the season. Underdog’s promotion specifically targets this high-profile primetime game, offering users a chance to bet on individual player performances—such as whether 49ers running back Christian McCaffrey will exceed 90 rushing yards or if Seahawks wide receiver DK Metcalf will record over 75 receiving yards.
**Analise**
The timing of the FOXNEWS promo code is strategic. Thursday Night Football consistently draws one of the largest television audiences of the week, and Underdog is leveraging that viewership to acquire new users at a lower cost than traditional advertising. By requiring only a $5 deposit, the platform removes the financial risk that often deters first-time users from trying daily fantasy or pick’em games. The $100 bonus is issued as bonus cash, which can be used across multiple contests but is subject to playthrough requirements—typically a 1x or 2x rollover before withdrawal. This structure ensures that users engage with the product while still providing a tangible reward.
From a market perspective, the promotion signals that Underdog is willing to spend aggressively to grow its user base ahead of the NFL season’s midpoint. The company has raised significant venture capital funding in recent years, allowing it to subsidize these high-value offers. For consumers, the deal represents one of the best risk-reward ratios currently available in legal sports gaming. However, users should read the full terms and conditions carefully, as bonus cash often expires after a set period and may not be available for all contest types. The Seahawks vs. 49ers game, with its divisional stakes and star power, provides an ideal entry point for new users to test the platform.
