BetMGM Maryland: Legit? Inside MGM's Own Casino

BetMGM Maryland: Legal Since 2021, Housed in Its Own Casino

BetMGM Maryland has run as a licensed sportsbook since the state opened retail wagering in December 2021 — and unlike almost every other operator here, its sportsbook sits inside a casino MGM Resorts itself owns and operates. That is not marketing color; it is a structural difference worth understanding before asking whether BetMGM is legit or safe in Maryland.

Legal status in Maryland

Maryland voters authorized sports wagering through the Question 2 referendum on November 3, 2020, and the General Assembly wrote the implementing rules into House Bill 940, signed by Governor Larry Hogan in 2021. HB 940 created the Sports Wagering Application Review Commission (SWARC) to award licenses, with suitability review handled by the Maryland Lottery and Gaming Control Commission (MLGCC). BetMGM holds both a retail license tied to MGM National Harbor and a mobile license, and has operated continuously under the Maryland Lottery and Gaming Control Agency (MLGCA) since. Online casino play has never been authorized in Maryland; the latest attempt, Senate Bill 761 and its companion SB 885, died in committee in March 2026. A separate 2025 law, House Bill 352, raised the tax on mobile sports wagering revenue from 15% to 20% starting with fiscal year 2026, while retail wagering stayed at 15%.

State gambling authority: Maryland Lottery and Gaming Control Agency (MLGCA), working from licenses awarded by SWARC and suitability findings from the Maryland Lottery and Gaming Control Commission.

When Maryland's retail sportsbooks opened on December 9, 2021, the state didn't hold its launch ceremony at a random casino floor — it held it at MGM National Harbor, where then-Governor Larry Hogan and Washington football legend Joe Theismann placed the first legal bets in the state. That venue happens to be the one BetMGM's sportsbook sits inside, and it happens to be a casino MGM Resorts itself owns and operates. That is the detail worth understanding before asking whether BetMGM is legit or safe here — this isn't a licensing deal with someone else's building.

Is BetMGM Legal in Maryland?

Yes, cleanly. Maryland's constitution requires any expansion of commercial wagering to clear a statewide vote, and Question 2 did that in November 2020 by a wide margin. The General Assembly spent the following year writing House Bill 940, which Governor Hogan signed in 2021. That law created the Sports Wagering Application Review Commission (SWARC) specifically to award licenses, with the Maryland Lottery and Gaming Control Commission handling suitability review behind each approval. BetMGM holds both halves of that structure: a retail license tied to MGM National Harbor and a separate mobile license.

Is BetMGM Legit in Maryland? The Casino Is the Tell

Most sportsbooks operating in Maryland lease a counter or a lounge inside a casino someone else built — FanDuel at Live! Casino & Hotel in Hanover, for instance. BetMGM doesn't need that arrangement. MGM National Harbor in Oxon Hill is an MGM Resorts property, operated by MGM alongside the local minority investors Prince George's County required as a licensing condition, and BetMGM's retail sportsbook sits on that same floor. Maryland regulators picked that exact location to host the state's official launch event. A brand hosting the ceremony that legitimized an entire state's sports betting market, inside a building it actually owns, is a different kind of legitimacy than a logo on a rented kiosk.

Two launches, a year apart: Retail betting at MGM National Harbor opened December 9, 2021. Mobile betting didn't follow until BetMGM soft-launched its Maryland app on November 21, 2022, going fully live statewide two days later alongside six other operators.

Is BetMGM Safe to Use in Maryland?

Yes. The MLGCA requires geolocation to confirm a bettor is physically inside Maryland, identity verification before a dollar moves, and ongoing oversight from both SWARC and the Lottery and Gaming Control Commission. That's the same regulatory floor every licensed Maryland operator stands on. It's a real backstop against an unregulated offshore book disappearing with a balance — it isn't a claim that the bets themselves are a good financial decision.

The Tax Went Up, But Not Everywhere

House Bill 352, signed in 2025, raised Maryland's tax on mobile sports wagering revenue from 15% to 20% starting with the fiscal year 2026 budget — a straightforward revenue grab aimed mostly at the Blueprint for Maryland's Future education fund, the same destination the original 2020 law earmarked. Retail wagering, including BetMGM's MGM National Harbor book, kept the original 15% rate. The split matters for the state's math, not for whether a bettor's account is handled correctly either way.

No Online Casino, and No Imminent Change

Maryland has never authorized iGaming. The latest attempt — Senator Ron Watson's SB 761 ballot-referendum bill, paired with the regulatory framework in SB 885 — died in March 2026 when the Senate Budget and Taxation Committee canceled SB 761's scheduled hearing. BetMGM Casino remains a four-state product: Michigan, New Jersey, Pennsylvania, and West Virginia. Maryland bettors get the sportsbook and nothing more, regardless of what the brand offers elsewhere.

Who It Fits

Maryland bettors 21 and older who want a sportsbook with a regulatory and ownership story they can actually verify — a license tied to a casino MGM runs itself, not a rented corner of someone else's floor. It doesn't make the odds better or the outcome more predictable. Treat it as entertainment spending, not income. If gambling stops being fun, call 1-800-GAMBLER.

BetMGM Maryland — Frequently Asked Questions

Is BetMGM legal in Maryland?

Yes. Maryland voters approved sports wagering under Question 2 in November 2020, the General Assembly implemented it through House Bill 940, and BetMGM holds both a retail license — tied to MGM National Harbor — and a mobile license issued through that framework. It has operated without interruption since Maryland's market opened.

Is BetMGM legit in Maryland, or is the MGM name just branding?

It's more than branding. BetMGM's Maryland retail sportsbook operates inside MGM National Harbor in Oxon Hill, a casino MGM Resorts itself owns and operates alongside local minority investors required under Prince George's County's licensing terms. When Maryland's retail market opened on December 9, 2021, the state's launch ceremony was held at that sportsbook, with then-Governor Larry Hogan and Washington football alumnus Joe Theismann placing the first bets there. Most competing books in Maryland lease space inside someone else's casino; BetMGM's is inside its own.

Is BetMGM safe to use in Maryland?

Yes. BetMGM operates under MLGCA licensing with geolocation confirming an in-state bettor, identity verification at signup, and oversight from both SWARC and the Maryland Lottery and Gaming Control Commission. That regulatory structure is the same one every one of Maryland's licensed mobile operators answers to — it does not make BetMGM's bets a safer financial decision, just a legally accountable one.

Does BetMGM have an online casino in Maryland?

No. Maryland has never authorized iGaming, and the most recent push to change that — Senator Ron Watson's SB 761 ballot-referendum bill and its regulatory companion, SB 885 — collapsed in March 2026 when the Senate Budget and Taxation Committee canceled SB 761's hearing. BetMGM Casino stays limited to Michigan, New Jersey, Pennsylvania, and West Virginia; Maryland bettors only get the sportsbook.

Did Maryland raise taxes on BetMGM?

Yes, on the mobile side. House Bill 352, signed in 2025, raised the tax on mobile sports wagering revenue from 15% to 20% starting with the state's fiscal year 2026 budget. Retail wagering — including BetMGM's sportsbook at MGM National Harbor — stayed at the original 15% rate. Most of that revenue is earmarked for the Blueprint for Maryland's Future education fund, a destination written into the 2020 law itself.

Where is BetMGM's retail sportsbook in Maryland?

Inside MGM National Harbor in Oxon Hill, which opened as one of Maryland's first retail sportsbooks on December 9, 2021. Mobile betting came almost a year later: BetMGM soft-launched its Maryland app on November 21, 2022, and went fully live statewide on November 23, 2022, alongside six other operators.
