Are Daily Fantasy Sports Leagues Legal?

Participation in daily fantasy sports for real money is legal in the US and Canada. The Unlawful Internet Gaming Enforcement Act (UIGEA) of 2006 contained exemptions since it’s a game of skill. The only exceptions are in Arizona, Iowa, Louisiana, Massachusetts, Montana, Nevada, New York, North Dakota, Oregon, Puerto Rico, Vermont, Virginia and Washington, where we do not operate because of state law.

See the excerpt from UIEGA below which distinguishes online sports betting versus participation in daily fantasy sports::

Fantasy Sports has a specific carve out in the Unlawful Internet Gambling Enforcement Act (UIGEA)
