In Massachusetts, where sports betting via the internet is now legal, DraftKings plans to open its online betting website on March 10th, subject to regulatory approval. The US sportsbook behemoth is legitimate in all other US states that permit sports betting, but the unveiling in Massachusetts is unique because it is the location of DraftKings' corporate headquarters and the place where it was established. In addition, DraftKings will provide users in The Bay State with expansive signup promotions to use its service, similar to what it did in a number of its other state launches.
