Best online sportsbook Michigan is a two-name race on volume — FanDuel ahead, DraftKings close behind — but the part worth actually understanding is how Michigan built the market those two names compete in. This is one of the only states where tribal nations and commercial casinos hold entirely separate, parallel paths to an online sports betting license, and that structure is still adding new operators five years after launch.
One Law, Two Licensing Tracks
Michigan's Lawful Sports Betting Act, signed by Governor Gretchen Whitmer in December 2019, didn't hand the market to a handful of commercial casinos the way most states do. It built two tracks at once: the three Detroit commercial casinos — MGM Grand Detroit, MotorCity, and Hollywood Casino at Greektown — can each authorize an online platform, and so can any of the state's 15 federally recognized tribes. DraftKings' original Michigan license, for instance, runs through the Bay Mills Indian Community, not a Detroit casino at all.
Michigan sports betting, by the numbers
- Launch date: January 22, 2021, noon
- Regulator: Michigan Gaming Control Board
- Licensing tracks: 15 tribes + 3 Detroit commercial casinos
- Tax rate: 8.4% of adjusted gross receipts on sports betting
- Tax split: tribal operators pay 8.4% to the state; commercial operators split 70% state / 30% City of Detroit
- Newest operator: bet365, approved April 2026 via the Little Traverse Bay Bands of Odawa Indians
FanDuel Ahead, DraftKings Close, BetMGM at Home
FanDuel carried roughly $111 million in Michigan handle in August 2026, worth $11.7 million in gross receipts and up 3.8% year over year. DraftKings held second at a $91.1 million handle — down 11.6% from a year earlier — and BetMGM sat a clear third at $32.9 million, a number that makes sense once you remember MGM Grand Detroit is a real casino on the Detroit River, not just a licensing deal on paper. Caesars and ESPN Bet fill out the established field, each riding one of the state's tribal or commercial authorizations.
The Market Keeps Growing Because the Cap Doesn't Exist
Most states fixed their sportsbook seat count years ago and haven't moved since. Michigan hasn't, because there's no single number of licenses to exhaust — any of 15 tribes can still bring on a new platform provider. That's exactly what happened in April 2026, when the Michigan Gaming Control Board approved Hillside Michigan LLC, doing business as bet365, to operate for the Little Traverse Bay Bands of Odawa Indians. It's a small operator by current handle, but it's proof the Michigan model isn't done adding names.
Worth Betting Legally in Michigan Now?
Yes, for anyone 21 or older physically in the state. FanDuel and DraftKings have run without interruption since the January 2021 launch, the tribal-commercial split is a licensing detail rather than something that touches a bettor's payout, and the state's active enforcement against unlicensed offshore books is a point in the legal market's favor, not against it. None of that makes sports betting a way to make money — it's 21-and-over entertainment with the house holding the edge, and the Michigan problem gambling helpline, 1-800-270-7117, is free around the clock.
The short list
- 1. FanDuel — Michigan's highest-volume app since at least 2025
FanDuel posted roughly $111 million in Michigan handle and $11.7 million in gross receipts in August 2026, up 3.8% year-over-year, the state's steady frontrunner.
- 2. DraftKings — A close second, licensed through Bay Mills Indian Community
DraftKings launched in Michigan on day one, January 22, 2021, tethered to the Bay Mills Indian Community, and still runs second at a $91.1 million August 2026 handle despite an 11.6% year-over-year dip.
- 3. BetMGM — Home-market edge from MGM Grand Detroit
BetMGM holds a commercial license through MGM Grand Detroit, one of the city's three commercial casinos, and carried about $32.9 million in handle and $4.5 million in revenue in August 2026.
- 4. Caesars Sportsbook — Running through a Detroit commercial license
Caesars Sportsbook operates in Michigan under a commercial license tied to one of Detroit's three casinos, part of the state's dual tribal-commercial licensing structure.
- 5. ESPN BET — Live under a tribal platform-provider deal
ESPN Bet operates in Michigan through a tribal gaming partnership, one of several national brands riding Michigan's model of licensing platform providers under existing tribal or commercial gaming authority.
The honest verdict
FanDuel is the practical pick on current volume — it carried about $111 million in Michigan handle in August 2026 and $11.7 million in gross receipts, up 3.8% year-over-year. DraftKings ran second at a $91.1 million handle and $9.4 million in revenue, down 11.6% from a year earlier, with BetMGM a distant third at $32.9 million in handle and $4.5 million in revenue — unsurprising in the one state where BetMGM's namesake casino anchors MGM Grand Detroit. Caesars and ESPN Bet round out the established field, each tethered to a tribal or commercial license the way every Michigan operator has to be. The newest name is bet365, approved by the Michigan Gaming Control Board in April 2026 to run as the internet platform provider for the Little Traverse Bay Bands of Odawa Indians — a reminder that Michigan's operator list isn't fixed the way it is in states with a flat cap on licenses. None of that changes what this still is: 21-and-over entertainment with a built-in house edge, not an income strategy, and the Michigan problem gambling helpline at 1-800-270-7117 is free and confidential.
Questions this list actually answers
What is the best online sportsbook in Michigan?
FanDuel on current volume — about $111 million in handle and $11.7 million in gross receipts in August 2026, up 3.8% year-over-year. DraftKings is close behind at a $91.1 million handle, with BetMGM a distant third at $32.9 million, boosted by its MGM Grand Detroit tie.
Is online sports betting legal in Michigan?
Yes. The Lawful Sports Betting Act, part of a package Governor Gretchen Whitmer signed in December 2019, authorized it, and the Michigan Gaming Control Board turned on retail and online wagering at noon on January 22, 2021 — one of the earliest and fastest-moving launches of that era.
Why does Michigan have so many sportsbook apps?
Because licensing runs two tracks at once. Fifteen federally recognized tribes and the three Detroit commercial casinos — MGM Grand Detroit, MotorCity, and Hollywood Casino at Greektown — can each authorize an online sports betting platform provider, so the operator list keeps growing instead of being capped at a fixed number of seats the way it is in most states.
Is bet365 available in Michigan?
Yes, as of April 2026. The Michigan Gaming Control Board approved Hillside Michigan LLC, doing business as bet365, to operate as the internet gaming and sports betting platform provider for the Little Traverse Bay Bands of Odawa Indians — the newest tribal-tethered launch in the state.
Does Michigan tax online sports betting differently than retail?
Yes, and the split runs through who holds the license, not the bet type. Online sports betting carries an 8.4% tax on adjusted gross receipts; tribal operators pay that full rate to the state, while commercial operators split it 70% to the state and 30% to the City of Detroit. Online casino play is taxed on a separate tiered schedule from 20% up to 28% depending on yearly receipts.
Who regulates online sports betting in Michigan?
The Michigan Gaming Control Board, which licenses both the tribal platform-provider deals and the three Detroit commercial casinos' online operators, and which issued cease-and-desist orders to 45 unlicensed offshore gambling sites in April 2026 as part of its enforcement push.
