BetMGM Maine: Locked Out of a Market That Already Picked Winners

BetMGM Maine is not a pending license or a gray-area workaround — it is a 23-state-plus-D.C. sportsbook that simply never got a seat at Maine's table. Maine legalized mobile sports betting back in 2023, built the whole market around four tribal licenses, and both available commercial slots filled before BetMGM's joint-venture ownership structure ever came up for a vote.

Legal status in Maine

Maine legalized online sports wagering under LD 585, signed by Governor Janet Mills in May 2022 and live for betting since November 3, 2023. Rather than license sportsbook operators directly, the law reserves mobile wagering rights for the state's four federally recognized tribes — the Passamaquoddy Tribe, the Penobscot Nation, the Houlton Band of Maliseet Indians, and the Mi'kmaq Nation — and lets each tribe pick exactly one commercial brand to run its app. The Passamaquoddy picked DraftKings. The other three tribes all picked Caesars Sportsbook. That fills every tribal slot the law allows, and BetMGM was not the brand either side chose. The statute also permits up to ten retail licenses for racetracks, casinos, and off-track betting facilities, but those are tribal and commercial-track licenses too, not a side door BetMGM can walk through the way it reaches Oregon or Washington bettors through a partner casino counter. Online casino is a newer, separate question: Governor Mills let LD 1164 become law without her signature on January 7, 2026, authorizing the same four tribes to each bring in one iGaming partner. As of this writing none of the four has publicly named one.

State gambling authority: Maine Gambling Control Unit (MGCU), Department of Public Safety — licenses the tribal sportsbook partnerships and, going forward, the iGaming partnerships created by LD 1164.

BetMGM Maine does not exist as a sportsbook, and the reason is timing more than anything else. Maine legalized mobile sports betting years ago, built the entire market around four tribal licenses, and both of the commercial brand slots those tribes could fill were already taken by the time anyone was asking whether BetMGM’s joint-venture ownership made it a good partner. It simply never got invited to that conversation.

How Maine’s Two Apps Filled Up Before BetMGM Showed Up

LD 585 took a different approach than most states that legalize sports betting. Instead of licensing sportsbook operators directly, Maine reserved mobile wagering rights for its four federally recognized tribes — the Passamaquoddy Tribe, the Penobscot Nation, the Houlton Band of Maliseet Indians, and the Mi'kmaq Nation — and let each one choose a single commercial brand to run the actual app. Betting went live November 3, 2023. The Passamaquoddy settled on DraftKings. The other three tribes all landed on Caesars Sportsbook. That is every license the law allows, filled by two operators, and neither negotiation ever involved BetMGM.

Live in Maine: DraftKings (Passamaquoddy Tribe) and Caesars Sportsbook (the other three tribes). Not live: BetMGM, or any commercial brand outside those two.

Is BetMGM Legit, Without a Maine Product to Point To?

Yes — legitimacy and local licensing are separate questions, and Maine is a clean example of why. BetMGM is still the 50/50 joint venture between MGM Resorts International and Entain, still live in 23 states plus D.C. as of September 2026, and still coming off a record 2025 by revenue. None of that changes because one small New England market happened to fill its two available slots with other brands first.

No Retail Side Door, Either

BetMGM reaches some dark-for-mobile states through a tethered retail model — Oregon and Washington bettors can use the app only while physically inside a specific partner casino. Maine's law does carve out up to ten retail sportsbook licenses in addition to the four mobile ones, but those retail seats also belong to the tribes and existing commercial tracks already running the market, not to BetMGM. There is no Maine casino floor where walking in with a phone would unlock the app the way it does out west.

How Safe Is Any of This for a Maine Bettor?

Split the question by what actually exists. DraftKings and Caesars operate here under real tribal licenses and Maine Gambling Control Unit oversight — a genuine regulatory backstop, the same kind BetMGM itself relies on in its 23 licensed states. There is no BetMGM account to evaluate the safety of in Maine, because the state never licensed one. Anyone reaching a BetMGM-branded product from a Maine IP address is outside whatever protections the state's tribal licensing structure provides.

The Door That Is Still Open: Online Casino

Maine's sportsbook story is settled, but its casino story just started. Governor Mills let LD 1164 become law without her signature on January 7, 2026, giving the same four tribes the right to each bring in one online casino partner. Nobody has announced a pick yet. BetMGM already runs a real, if narrow, casino product — Michigan, New Jersey, Pennsylvania, and West Virginia only — so unlike the sportsbook race it already lost, the iGaming race in Maine has not been run.

Sportsbook slots: 4 tribal licenses, all 4 claimed (DraftKings x1, Caesars x3) since November 2023. iGaming slots: 4 tribal licenses authorized January 7, 2026, 0 publicly claimed as of this writing.

What This Means If You're in Maine

There is no BetMGM sportsbook to sign up for here, and nothing on the horizon suggests that changes — both tribal slots are spoken for and neither tribe has signaled a switch. The casino side is a different, open story worth watching if a tribe announces an iGaming partner. Until then, treat any gambling as entertainment spending, not income, 21+ where it is actually legal, and call 1-800-GAMBLER if it stops feeling that way.

BetMGM Maine — Frequently Asked Questions

Is BetMGM legal in Maine?

Not as a sportsbook a Maine resident can download. Maine legalized mobile sports betting in 2023, but it did so by handing four exclusive licenses to its federally recognized tribes rather than opening a bid process BetMGM could enter. The Passamaquoddy Tribe partnered with DraftKings; the Penobscot Nation, the Houlton Band of Maliseet Indians, and the Mi'kmaq Nation all partnered with Caesars. Both commercial seats are filled, and neither belongs to BetMGM.

Is BetMGM safe to use from a Maine address?

There is no BetMGM account to open from Maine, so the usual licensing-and-geolocation safety checklist does not apply here the way it would in New Jersey or Michigan. What is worth knowing: Maine's sports wagering law applies only to the licensed tribal operators, and the state has not pursued individual bettors who use offshore or out-of-state apps — but no regulator stands behind a Maine BetMGM account, because none exists.

Is BetMGM legit, even with no Maine product?

As a company, yes. BetMGM is the 50/50 joint venture between MGM Resorts International and Entain, licensed and operating in 23 states plus Washington D.C. as of September 2026, and it posted roughly $2.8 billion in net revenue in 2025. Maine's absence from that list is a function of the state's four-tribe licensing cap filling up in 2023, not any doubt about BetMGM's standing elsewhere.

Why did both tribal slots go to DraftKings and Caesars instead of BetMGM?

Maine never ran a process that pitted the three brands against each other in public. Each tribe negotiated its own commercial partnership privately and chose a partner on its own timeline — the Passamaquoddy settled on DraftKings, and the other three tribes converged on Caesars. Nothing in LD 585 required considering BetMGM specifically, and nothing in the public record points to why the tribes went the way they did. It was not a bid BetMGM lost; it was a negotiation BetMGM was not part of.

Does BetMGM reach Maine through a retail counter, like it does in Oregon or Washington?

No. In Oregon and Washington, BetMGM uses a tethered model — a bettor has to be physically present at a specific partner casino to use the app. Maine's law does allow up to ten retail sportsbook licenses alongside the four mobile ones, but those retail licenses also run through the tribes and commercial tracks already in the market, not through BetMGM. There is no physical location in Maine where opening the BetMGM app would work.

Could BetMGM Casino get into Maine through the new iGaming law?

That is a genuinely open question, unlike the sportsbook one. LD 1164, effective January 7, 2026, lets each of the same four tribes bring in one online casino partner, and as of this writing none has announced a choice publicly. BetMGM already runs a real casino product — just a narrower one than its sportsbook, limited to Michigan, New Jersey, Pennsylvania, and West Virginia today — so a Maine tribe choosing BetMGM as its iGaming partner is plausible in a way a BetMGM sportsbook no longer is. Nothing has been announced, and the sportsbook slots filling up first with other brands is not a guarantee about how the iGaming slots go.
