Flutter Entertainment is an Irish-American multinational and the world's largest online betting company, owning well-known brands such as Paddy Power, Betfair, FanDuel, and PokerStars. It was created in 2016 through the merger of Paddy Power and Betfair, and rebranded as Flutter in 2019 to better reflect its growing family of consumer brands. A major turning point came in 2018 when it acquired a controlling stake in FanDuel, making it a powerhouse in the US sports betting market after the federal prohibition was overturned. In 2019, Flutter acquired The Stars Group for $6.95 billion, cementing its status as the global revenue leader in online gambling. Listed on both the New York and London Stock Exchanges, the company has also faced regulatory scrutiny, including a £2.2 million fine in 2018 for failing to protect problem gamblers and inadequate anti-money laundering checks.
