Description of Business	Description of Business We are a digital sports entertainment and gaming company. We provide users with online and retail sports betting (together, “Sportsbook”), online casino (“iGaming”) and daily fantasy sports (“DFS”) product offerings, as well as digital lottery courier, media, and other product offerings. In May 2018, the U.S. Supreme Court (the “Court”) struck down on constitutional grounds the Professional and Amateur Sports Protection Act of 1992, a law that prohibited most states from authorizing and regulating sports betting. As of June 30, 2025, 39 U.S. states, the District of Columbia and Puerto Rico have some form of authorized sports betting. Of those 41 jurisdictions, 33 have legalized online sports betting. 32 of those 33 jurisdictions are live, and DraftKings operates in 26 of them. As of June 30, 2025, the U.S. jurisdictions with statutes legalizing iGaming are Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island and West Virginia. As of June 30, 2025, we operate our Sportsbook product offering in Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Vermont, Virginia, Washington, D.C., West Virginia, Wyoming and Ontario, Canada, and we operate retail sportsbooks in Arizona, Colorado, Connecticut, Illinois, Iowa, Kansas, Kentucky, Louisiana, Michigan, Mississippi, New Hampshire, New Jersey, Washington and Wisconsin.
