Caesars Washington DC: Legal, and the Original Arena Book

Caesars Washington, D.C.: Legal, From the Original Arena Book

Caesars Washington, D.C. is legal district-wide, and the sportsbook behind it predates the Caesars name in the city. The Capital One Arena book that anchors Caesars’ D.C. license opened in May 2021 as William Hill’s sportsbook — reportedly the first retail sportsbook built inside a US professional sports venue — months before the William Hill-to-Caesars rebrand reached it. That history, not a 2024 startup story, is the real answer to whether Caesars is legal, legit, and safe to use here.

Legal status in Washington, D.C.

D.C. legalized sports wagering under the Sports Wagering Lottery Amendment Act of 2018, which capped commercial sportsbooks at four Class A licenses tied to specific venues: Audi Field, Capital One Arena, Nationals Park, and Elizabeths East. William Hill partnered with Monumental Sports & Entertainment, the arena's owner, in October 2019 and opened the Capital One Arena book in May 2021; the William Hill-to-Caesars rebrand followed that August. For nearly three years, Caesars' D.C. mobile betting only worked inside a roughly two-block radius around Capital One Arena, while the D.C. Lottery's own app (GambetDC, later rebuilt on FanDuel's platform) handled mobile bets everywhere else in the District. The Sports Wagering Amendment Act of 2024, which took effect July 15, 2024 after a budget-signing dispute briefly accelerated its timeline, let existing Class A licensees take mobile bets anywhere in D.C. rather than just near their venue. Caesars and BetMGM both went district-wide within days of each other that July. The D.C. Council paired the expansion with a tax hike, raising the Class A rate from 10% to 20% of gross gaming revenue effective August 1, 2024. In September 2024, the Office of Lottery and Gaming also approved Caesars as the District's exclusive sports-betting kiosk supplier, putting self-service kiosks into 53 D.C. businesses and replacing GambetDC's old retail kiosk role.

State gambling authority: D.C. Office of Lottery and Gaming (OLG)

Caesars Washington, D.C. has been legal district-wide since July 15, 2024, but the sportsbook behind that license is older than the Caesars name in this city. The Capital One Arena book opened in May 2021 under the William Hill brand, months before the William Hill-to-Caesars rebrand reached it — and it’s reportedly the first retail sportsbook ever built inside a US professional sports venue, predating BetMGM’s Nationals Park book by nearly eight months.

Is Caesars Legal in D.C.? The Capital One Arena License

D.C.’s 2018 sports-betting law capped commercial sportsbooks at four Class A licenses, each tied to a specific venue: Audi Field, Capital One Arena, Nationals Park, and Elizabeths East. William Hill partnered with Monumental Sports & Entertainment, the arena’s owner, in October 2019 and opened the book in May 2021 — first as a temporary setup inside the box office, later expanded in 2022 to add betting windows, kiosks, and a Guy Fieri restaurant concept. The William Hill-to-Caesars rebrand landed that August, so Caesars inherited an already-open, already-operating license rather than starting one from scratch.

The two-block catch, for nearly three years: the original Class A license only let Caesars take mobile bets within about two blocks of Capital One Arena. Everywhere else in the District, the only mobile sportsbook was the D.C. Lottery’s own app — first GambetDC, later rebuilt on FanDuel’s platform.

What Changed in 2024

The Sports Wagering Amendment Act of 2024 let existing Class A licensees — Caesars and BetMGM both — take mobile bets anywhere in D.C., not just near their venue. A budget-signing dispute at the mayor’s office briefly pushed the law’s effective date up, but Caesars and BetMGM went live district-wide within days of each other on July 15, 2024. The D.C. Council paired the expansion with a tax increase, raising the Class A rate from 10% to 20% of gross gaming revenue effective August 1, 2024.

Caesars also runs the kiosks: in September 2024, D.C.’s Office of Lottery and Gaming approved Caesars as the District’s exclusive supplier of self-service sports-betting kiosks, placing them in 53 local businesses and replacing the retail-kiosk role GambetDC used to hold. It’s a separate approval from the mobile license, but the same operator underneath.

Is Caesars Legit in D.C.?

Yes, and the Capital One Arena book is the strongest evidence of it in the District. It predates the market’s 2024 expansion by three years, it survived a corporate rebrand without interruption, and it runs on the same Liberty betting platform Caesars uses in roughly two dozen other licensed states. That’s a long, continuous operating record inside a single arena, not a brand that showed up for the 2024 gold rush.

How Safe Is Caesars in D.C.?

The D.C. Office of Lottery and Gaming licenses and audits Caesars’ Class A sportsbook the same way it oversees every other operator in the District, with geolocation confirming the bettor is physically inside D.C. and the usual self-exclusion and deposit-limit tools available in the app. There’s no Caesars Palace Online Casino here — D.C. hasn’t legalized online casino play at all, so the license covers sports wagering only.

Who It Fits

Adults 21+ physically located in D.C. who want a sportsbook with the longest continuous retail track record in the city, now without the old two-block restriction. Caesars isn’t the only citywide option — FanDuel runs the Lottery’s own platform and BetMGM holds the Nationals Park license — but Caesars’ arena book has been open the longest of any of them.

Caesars Sportsbook Washington, D.C. — Frequently Asked Questions

Is Caesars legal in Washington, D.C.?

Yes, district-wide, since July 15, 2024. Caesars holds a Class A sportsbook license tied to its retail book at Capital One Arena, and a 2024 law let that license cover mobile betting anywhere in D.C. instead of just the blocks around the arena.

Why was Caesars limited to a small area of D.C. before 2024?

Because that's what the original Class A license allowed. D.C.'s 2018 law tied each of its four Class A licenses to one venue and let mobile betting work only within about two blocks of it, carving out the territory the D.C. Lottery's own citywide app didn't reach. Outside that radius, the Lottery's app was the only mobile option in the District.

Is Caesars legit in D.C., given the Capital One Arena book?

Yes — it's arguably the most credentialed retail book in the city. The sportsbook opened inside Capital One Arena in May 2021 under a partnership between William Hill and Monumental Sports & Entertainment, reportedly the first retail sportsbook ever built inside a US professional sports venue. Caesars Entertainment inherited it in the 2021 acquisition and rebrand, and it's run on the same Liberty betting platform Caesars uses in roughly two dozen other states.

Is Caesars safe to use in D.C.?

Yes. The D.C. Office of Lottery and Gaming licenses and audits Caesars’ Class A sportsbook under the same framework it applies to every operator in the District, with geolocation confirming the bettor is physically inside D.C. and standard self-exclusion and deposit-limit tools available in the app.

Does Caesars run D.C.’s sports-betting kiosks, too?

Yes. In September 2024, the Office of Lottery and Gaming approved Caesars as the District's exclusive supplier of self-service sports-betting kiosks, placing them in 53 D.C. businesses and taking over the retail-kiosk role GambetDC used to hold. That's separate from the mobile app, but it's the same Caesars license underneath.

Does Caesars have an online casino in D.C.?

No. D.C. has not legalized online casino play at all, and Caesars Palace Online Casino only operates in New Jersey, Pennsylvania, Michigan, and West Virginia. The Capital One Arena license covers sports wagering only.
