Gambling.com Group operates two businesses serving the online gambling industry: a performance marketing affiliate business and a sports data services business. The marketing business, which accounts for roughly 75% of revenue, attracts consumers to a portfolio of branded websites — including Gambling.com, Bookies.com, and Casinos.com — where they compare and find online casinos and sportsbooks. When a visitor registers and deposits at an operator, Gambling.com earns a fee from that operator. The company works with major operators including Flutter, DraftKings, BetMGM, and Caesars across 22 national markets. Gambling.com is paid through revenue share (an ongoing cut of a referred player's net spend over their lifetime), a fixed CPA per new depositing customer, or a hybrid of both. Historically, traffic has been driven primarily by SEO, which carries high margins but creates vulnerability to Google algorithm changes — a headwind the company experienced in 2025. Gambling.com is actively diversifying into email, social, and paid media channels to reduce this dependency. The data services segment, roughly 25% of revenue, sells real-time sports betting odds data and fantasy sports content via subscription. The OpticOdds brand serves enterprise clients like sportsbook operators who need real-time odds feeds; OddsJam serves individual sports bettors; and RotoWire serves both media companies and fantasy sports players. This segment aggregates data across 350+ sportsbooks at sub-500 millisecond latency, a capability Gambling.com argues is difficult and uneconomical for most operators to replicate internally.
