Underdog Fantasy Sports has launched a promotional offer for the upcoming MLB Division Series between the New York Yankees and the Tampa Bay Rays, allowing new users in eligible states to deposit just $5 and receive $100 in bonus funds by using the promo code FOXNEWS. The promotion, advertised across FOX News digital platforms, is designed to attract a wave of new customers during one of baseball’s most-watched postseason rounds. The move underscores the aggressive customer-acquisition strategies that define the rapidly expanding US sports betting market, where platforms compete fiercely for market share through sign-up bonuses and media partnerships.
**Context**
The promotion comes as the MLB postseason enters its critical division series stage, with the Yankees and Rays facing off in a best-of-five matchup that draws significant viewership and betting interest. Underdog Fantasy Sports, a company that started as a daily fantasy sports operator and later expanded into sports betting, has been using high-value deposit matches and risk-free bets to build its user base. The FOXNEWS promo code is part of a broader trend of sportsbooks aligning with media outlets to gain credibility and reach. FOX News, a major cable news network, has increasingly integrated sports betting content into its programming, including segments on odds and picks. While the exact financial terms of the arrangement between Underdog and FOX News are not publicly disclosed, such cross-promotions typically involve revenue-sharing or flat-fee advertising deals.
The offer itself is structured as a deposit match: a new user deposits $5, and Underdog credits the account with $100 in bonus bets. The bonus funds are subject to wagering requirements, meaning users must place bets with the bonus money before any winnings can be withdrawn. This model is standard in the industry, as it encourages engagement while limiting the operator’s immediate liability. The Yankees-Rays series provides a high-stakes, high-attention event that maximizes the promotion’s visibility. Sportsbooks often time their biggest offers around marquee sporting events—the Super Bowl, March Madness, and the World Series—to capitalize on peak consumer interest.
The US sports betting market has grown exponentially since the Supreme Court struck down the federal ban on sports wagering in 2018. As of 2025, more than 30 states have legalized some form of sports betting, with New York, New Jersey, and Pennsylvania leading in handle. The industry is now a multi-billion-dollar sector, with operators spending heavily on marketing. Customer acquisition costs (CAC) have risen sharply, with some platforms spending hundreds of dollars to acquire a single user. Promotions like Underdog’s “Play $5, Get $100” are loss leaders designed to build a user base that will generate long-term revenue through repeat betting and cross-selling of other products like daily fantasy contests.
**Analise**
This promotion is economically significant for several reasons. First, it highlights the intense competition among sportsbooks for a finite pool of new bettors. With the market maturing, operators are forced to offer increasingly generous incentives to stand out. Underdog, while smaller than giants like DraftKings and FanDuel, has carved out a niche by focusing on a younger, more casual audience and by leveraging social media and influencer partnerships. The use of the FOXNEWS code specifically targets a demographic that trusts the FOX brand—often older, more conservative viewers—who may be new to legal sports betting. This strategic targeting reflects a sophisticated understanding of market segmentation.
Second, the promotion reveals the economics of customer lifetime value (LTV). A $100 bonus on a $5 deposit represents a 20-to-1 ratio, which is unusually high even by industry standards. For Underdog to justify this cost, it must be confident that the average new user will deposit and wager enough over time to recoup the outlay. Industry estimates suggest that the average sports bettor has an LTV of several hundred dollars, but churn rates are high—many users sign up for a bonus, use it, and never return. Operators therefore rely on a small percentage of heavy bettors to subsidize the majority. The Yankees-Rays series, with its high volatility and multiple games, provides ample opportunity for users to place bets and potentially lose their bonus funds, accelerating the operator’s path to profitability.
Third, the promotion underscores the symbiotic relationship between media companies and sportsbooks. FOX News, like many media outlets, has faced declining linear television viewership and is diversifying into digital revenue streams. Sports betting partnerships offer a new source of advertising income and audience engagement. In return, sportsbooks gain access to a trusted editorial environment and a built-in audience. This trend is not without controversy—some critics argue that it normalizes gambling and exposes vulnerable viewers to addiction risks. However, from an economic perspective, the integration of betting content into news media is a logical response to market demand and regulatory shifts.
