Underdog, a rapidly growing sports betting and daily fantasy sports platform, has launched a promotion that allows users to play $5 and receive $100 in bonus bets for the upcoming college football game between Iowa and Ohio State. The offer, accessed with the promo code FOXNEWS, is part of a broader strategy by sportsbooks to attract new customers in an increasingly crowded market. The promotion underscores the economics of customer acquisition in the U.S. sports betting industry, where operators are willing to offer substantial upfront incentives to gain market share.
**Context**
Since the U.S. Supreme Court struck down the Professional and Amateur Sports Protection Act (PASPA) in 2018, sports betting has expanded rapidly across the country. As of 2026, more than 30 states have legalized sports wagering, creating a fiercely competitive landscape. Major players like DraftKings, FanDuel, BetMGM, and Underdog are vying for a slice of the market, which the American Gaming Association estimates generates tens of billions of dollars in annual handle. To stand out, operators frequently deploy sign-up bonuses, risk-free bets, and deposit matches. Underdog’s latest offer — a $5 stake yielding $100 in bonus bets — is among the most aggressive, representing a 20-to-1 return on the initial wager.
The promotion is tied to a high-profile college football matchup: the Iowa Hawkeyes vs. the Ohio State Buckeyes, a Big Ten conference game that draws significant national attention. The use of the FOXNEWS promo code indicates a marketing partnership with Fox News, leveraging the network’s broad audience to drive new user sign-ups. Underdog, founded in 2020, initially focused on daily fantasy sports before expanding into sports betting. The company has positioned itself as a challenger brand, emphasizing user-friendly interfaces and innovative promotions.
**Analysis**
The economics behind such promotions are driven by the high customer acquisition cost (CAC) typical in the sports betting industry. Industry analysts note that operators often spend hundreds of dollars to acquire each new user, factoring in marketing expenses, bonus offers, and affiliate commissions. The lifetime value (LTV) of a bettor — which includes recurring deposits, wagering volume, and potential cross-selling of other products — must exceed the CAC for the business model to be sustainable. Underdog’s $5-to-$100 offer is a calculated risk: the upfront cost of $100 in bonus bets is high, but the company expects that a portion of new users will become regular customers, generating long-term revenue.
However, the aggressive promotion also attracts scrutiny from regulators. Several states have implemented rules to limit the size and frequency of bonus offers, citing concerns about problem gambling and consumer protection. For example, Ohio and New Jersey have capped the value of sign-up bonuses or required clear disclosure of terms. Underdog’s offer is likely structured as a series of bonus bets that must be used within a specific timeframe, with wagering requirements that reduce the effective value. Such mechanics are common in the industry to manage risk and ensure that the promotion remains profitable for the operator.
The Iowa vs. Ohio State game itself is a major driver of betting volume. College football, particularly rivalry games and conference matchups, attracts substantial wagering interest. The promotion may also be timed to capitalize on the start of the college football season, when fan engagement is at its peak. By tying the offer to a specific game, Underdog can measure the effectiveness of the campaign and adjust future strategies.
From a broader economic perspective, the proliferation of sports betting promotions reflects the maturation of the U.S. market. As legalization spreads, competition intensifies, and operators must find new ways to differentiate themselves. The partnership with Fox News — a major media outlet — highlights the convergence of sports media and gambling. Similar deals have been struck between sportsbooks and networks like ESPN, CBS, and NBC, creating a symbiotic relationship where media companies earn revenue from advertising and affiliate fees while sportsbooks gain access to large audiences.
