DraftKings Inc (NASDAQ:DKNG) is facing a class-action lawsuit for allegedly deceptive advertising related to its $1,000 bonus bet offer. The suit claims the terms were misleading, requiring a $5,000 deposit and $25,000 wager within 90 days to qualify. The bonus was also non-withdrawable credit. The Public Health Advocacy Institute, known for litigation against addictive product manufacturers, filed the suit, drawing attention to the risks of addiction in sports betting. DraftKings' stock value has tripled this year, and the lawsuit is supported by Richard Daynard, a legal expert who previously led actions against Big Tobacco.
