About
Kambi Group is a leading B2B provider of sports betting services, headquartered in Stockholm, Sweden, and publicly traded on Nasdaq First North Growth Market. Founded in 2010 as a spin-off from Unibet, Kambi provides the complete sports betting technology stack — including odds compilation, risk management, trading operations, and front-end sportsbook software — to regulated gaming operators across North America, Europe, Latin America, and Asia-Pacific. Its clients include major brands such as Penn Entertainment, Rush Street Interactive, and 888sport.\n\nThe Kambi platform handles billions of betting transactions annually across pre-match and in-play markets covering over 200,000 live events per year. The company employs a large team of traders and risk managers who work alongside automated algorithms to set lines and manage exposure. This hybrid human-plus-technology approach to trading is a key differentiator from pure-software competitors. Kambi's managed services model means operators can launch sportsbooks quickly without building proprietary trading infrastructure.\n\nKambi has been central to the rapid expansion of regulated sports betting in the United States following the 2018 Supreme Court ruling that overturned PASPA. The company partnered with multiple US operators to provide the underlying sportsbook platform during the state-by-state legalization wave. While competition from in-house technology builds by large operators has intensified, Kambi continues to invest in its platform capabilities and has expanded its client base in emerging regulated markets globally.
