FanDuel Group is a major American gambling company, headquartered in New York City, that offers sports betting, daily fantasy sports (DFS), horse racing, and online casino services. Originally founded in Edinburgh, Scotland in 2009 by Nigel Eccles and others, the company grew into a billion-dollar enterprise by 2015, directly rivaling DraftKings in the DFS market. In May 2018, FanDuel merged with the U.S. operations of Irish bookmaker Paddy Power Betfair (now Flutter Entertainment), which used FanDuel's brand to expand into sports betting across states like New Jersey and Pennsylvania. A proposed 2016 merger with DraftKings was blocked by the Federal Trade Commission in 2017, which argued the combined entity would hold a 90% monopoly on daily fantasy sports. FanDuel also made headlines in 2015 when a DraftKings employee inadvertently leaked data and won $350,000 on FanDuel, prompting rules against employees playing at rival sites. Today, FanDuel Group operates sportsbooks in multiple U.S. states, making it a dominant force in the rapidly growing legal sports betting industry.
