Caesars Sportsbook's legal states

Caesars Sportsbook takes online bets in Arizona, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Wyoming, plus D.C. and Puerto Rico. Regulators in most of them list Caesars or its operating company, American Wagering, Inc., as licensed. It doesn't take online bets in the other eight states where mobile betting is legal, or in any of the 11 states with no legal sportsbook.

The app checks your location before every bet, so the state you're standing in is what counts. An Illinois resident can bet on Caesars while visiting Indiana, and the same account stops working on the drive home to Wisconsin, where Caesars doesn't operate.

Novig, a CFTC-regulated prediction market, is available in every state except Nevada, Arizona and Michigan, with its status in Ohio and Missouri contested.

How the licenses work

Caesars owns casinos in many of its states, and in those it usually bets under its own property's license: Horseshoe Baltimore in Maryland, Harrah's Philadelphia in Pennsylvania, Caesars Virginia in Danville. Where it doesn't own a casino, it partners with someone who holds a license. That's the Arizona Diamondbacks, Grand Victoria in Elgin, Illinois, Red Mile in Lexington and Kansas Crossing in Pittsburg, Kansas. In Massachusetts, Caesars holds a Category 3 online license tethered to Encore Boston Harbor, and the app launched there on March 10, 2023.

In three states, Caesars operates under a tribe's license. In North Carolina, it runs the Eastern Band of Cherokee Indians' license, which ties it to Harrah's Cherokee. In Michigan it runs online betting for the Grand Traverse Band of Ottawa and Chippewa Indians. Maine's law gives mobile betting to the four Wabanaki Nations, and Caesars is the partner of three of them, the Houlton Band of Maliseet Indians, the Mi'kmaq Nation and the Penobscot Nation, with DraftKings working with the Passamaquoddy Tribe.

The newest state is Missouri. Voters approved Amendment 2 in November 2024, and Caesars took its first bets there on December 1, 2025, online and at Harrah's Kansas City and Horseshoe St. Louis. The Missouri guide covers that state's launch. In D.C., Caesars holds the Class A license at Capital One Arena, and it also runs betting kiosks at lottery retailers across the District.

Nevada: a separate app, in-person sign-up

Nevada licenses sports betting through its casinos, and Caesars runs its Nevada book under the Caesars name with its own app. Nevada law requires mobile sports wagering accounts to be activated in person, so you can download the app anywhere but need to show ID at a Caesars sportsbook before your first bet. Caesars lists hundreds of Nevada locations, among them Caesars Palace, Harrah's and the Flamingo, and many bar kiosks that came over with the William Hill business. The Nevada guide explains the in-person rule and its history.

Where the app works only inside a casino

Mississippi allows mobile sports betting only on a casino's premises, so the Caesars app there works only at properties such as Harrah's Gulf Coast in Biloxi and Horseshoe Tunica. Washington limits sports betting to tribal casinos, and Caesars runs the sportsbook at Muckleshoot Casino Resort, where the app works on-site, plus a betting kiosk at Mistequa Casino Hotel in Chewelah.

Caesars also has retail-only operations in Nebraska, at Harrah's Columbus, and in New Mexico, at tribal casinos including Inn of the Mountain Gods. Its Oregon presence is a kiosk at Ko-Kwel Casino. In Florida the Caesars site sends visitors to a William Hill horse racing book, and Hard Rock Bet remains the only legal sportsbook app under the Seminole compact.

Caesars online casino states

Caesars runs online casinos in Michigan, New Jersey, Pennsylvania and West Virginia, the only places it offers both sportsbook and casino games on its apps. It uses two brands, Caesars Palace Online Casino and Horseshoe Online Casino, though not both in every state. In June 2026, Caesars announced plans with the three Wabanaki Nations it partners with to launch online casino games in Maine after the state finishes its rules, and that hadn't launched by late October.

States without Caesars Sportsbook

Online betting is legal in Arkansas, Connecticut, Delaware, Florida, New Hampshire, Oregon, Rhode Island and Vermont, but Caesars doesn't take online bets in any of them. Several of those markets have only one or a few licensed apps, often run for the state lottery or a tribe. The guide on how to check a sportsbook's license covers each state's regulator list.

In the 11 states with no legal sportsbook, Caesars can't take bets at all. CFTC-regulated prediction markets, Novig among them, list sports contracts in most of them.
