Northern Ireland native Nigel Eccles cofounded FanDuel in 2009, at a time when fantasy sports was still just a niche hobby for diehard sports fans. He and his cofounders disrupted the industry by introducing daily fantasy sports—as opposed to season-long fantasy sports, which had long been the norm—thus allowing fans to compete more frequently. This model quickly caught on, bolstered by FanDuel’s partnerships with a number of NBA and NFL teams, with the company awarding $560 million in cash prizes in 2014. But Eccles and his company, as well as its major competitor, DraftKings, have recently come under fire from regulators for alleged insider trading, false advertising, and other malfeasance. Laws vary from state to state, and Eccles denies the accusations, but regulations that would strangle the industry continue to pose a threat.
