Is sports betting legal in Nevada?
Yes. Nevada licenses sports books in person and through wagering accounts you can use on your phone inside the state, for adults 21 and over, regulated by the Nevada Gaming Control Board and Nevada Gaming Commission.
The oldest legal market
Nevada is where legal betting in America grew up. The Nevada Gaming Control Board dates the state's modern era of legal gaming to 1931, when the "Wide Open Gambling" bill was signed, and the Board itself to 1955. Sports books are licensed as "sports pools" under Nevada's gaming statutes and run under Regulation 22, Race Books and Sports Pools. The Board's documents I read don't give a single date when sports betting started, so I won't put one here.
The age is 21. The Board's own court filing cites NRS 463.350: a person under 21 may not play, place wagers at or collect winnings from any game or sports pool.
How the accounts work
You can bet at the counter in any casino with a book, or from your phone through a wagering account with a licensed book. The phone part comes with a catch most visitors don't expect. Regulation 22 says that before a book takes a sports bet over an account, the patron has to show a government picture ID to an employee in person, at the book or at a place the Board has approved, under Regulation 5.225. And every account holder has to acknowledge that betting from outside Nevada is prohibited by law. So the app works on the Strip and in Reno. It doesn't work once you've driven home to California.
I like Nevada books for one reason above the rest: there are a lot of them, and they don't all hang the same number. If you're in Las Vegas I'd carry two or three accounts and shop every bet. The half point you pick up by walking across the street is the cheapest edge you'll ever find.
Winnings are taxable income; the IRS is clear on that.
Where the offshore books fit
Offshore books aren't licensed by Nevada, and the Board treats unlicensed wagering as unlawful in the state. A Nevada book that shorts you answers to a regulator with real teeth. An offshore one answers to nobody you can reach. Our offshore sportsbooks page explains the difference, and the VPN page covers why faking your location gets accounts closed.
Nevada books have to show account holders the 24-hour Problem Gamblers HelpLine, 1-800-522-4700, and our responsible gambling guide covers the limits you can set on an account.
