DraftKings is an American gambling and technology company, best known for its offering in daily fantasy sports (DFS). Founded in 2012, it quickly grew to become one of the largest players in the American gambling market. DraftKings gave sports fans a new way to win money by creating fantasy teams and earning points based on the performances of real players – usually in games played within a single day or weekend.

In addition to fantasy sports, DraftKings has also been active as an online bookmaker and casino operator since the legalization of sports betting in the US (as of 2018). The company now offers sports betting, online casino games, and even live dealer games in states where this is legal.
