Is Sports Betting Legal in Michigan? Yes, Plus Online Casino (2026)

✓ Last verified: 2026-08-13

Yes. Sports betting is legal in Michigan, both online and at casinos, for anyone 21 or older. Retail sportsbooks opened at Detroit’s casinos in March 2020, and statewide mobile betting launched on January 22, 2021. Michigan is one of the deepest markets in the country, and it is something most states are not: a full online-casino state too. On the same January 2021 day, Michigan became the first US state to switch on online sports betting, online casino, and online poker all at once. That dual market puts it in the same tier as New Jersey and Pennsylvania.

If you are 21+ and inside Michigan, about a dozen apps are competing for your action. Here is how it works.

How Michigan got here

Governor Gretchen Whitmer signed the Lawful Sports Betting Act in December 2019, part of a bipartisan package that legalized sports betting, online casino, and online poker together. The rollout came in two stages:

Retail first. MGM Grand Detroit and Greektown Casino took Michigan’s first legal sports bets on March 11, 2020, with MotorCity Casino a day later, just before COVID-19 closed the casinos.
Online next. Mobile sports betting, online casino, and online poker all went live together at noon on January 22, 2021, run through the Detroit commercial casinos and Michigan’s tribal casinos. Michigan is frequently cited as the first state to open all three online verticals on a single day.

Everything is regulated by the Michigan Gaming Control Board (MGCB).

The dual market: sports betting AND online casino

This is Michigan’s defining feature. Unlike Ohio, New York, or most states, Michigan runs a full legal online casino alongside sports betting. That makes it one of only about seven states with legal iGaming, and a genuine peer of New Jersey and Pennsylvania.

The scale is enormous: Michigan’s online gambling revenue set a record in 2025, and its online casino win of roughly $3.1 billion trailed only Pennsylvania. The gap has been closing fast: in June 2026 the two states finished within about $2 million of each other for the month. Treat any annual ranking with care, because the two regulators do not publish the figure the same way and trackers often quote a different measure than the state itself does. For a Michigan bettor, that means the same licensed apps often offer both a sportsbook and a full casino under one account.

The tax

Michigan taxes sports betting at 8.4% of receipts, applied to both online and retail, and the rate has not changed since launch. For the three Detroit commercial casinos, that 8.4% is split between the state and the City of Detroit rather than added on top, with a separate 1.25% municipal services fee. Online casino is taxed far more heavily, on a graduated scale of roughly 20% to 28%. A 2026 budget push to raise the iGaming tax and add a per-bet sportsbook fee was stripped out before it became law, so the rates held.

At 8.4%, Michigan is one of the gentler-taxed competitive markets, well below New York’s 51% or Pennsylvania’s 36%, which generally means better promotions and pricing for bettors.

Who you can bet with

Michigan has 13 live sportsbook apps:

bet365, FanDuel, DraftKings, BetMGM, Caesars, BetRivers, Fanatics, FireKeepers, theScore Bet, Four Winds, Eagle Casino & Sports, betPARX, and Hard Rock Bet.

Every app has to tether to a licensed casino, either one of the three Detroit commercial casinos or one of Michigan’s 12 federally recognized tribes, which caps the market at 15 online-gaming licenses. FanDuel (via MotorCity) and DraftKings lead; BetMGM is the Detroit hometown book at MGM Grand. The roster is still growing: ESPN BET became theScore Bet in December 2025, Hard Rock Bet launched in December 2025, Fanatics launched in February 2026, and bet365 launched in April 2026. You must be 21+ and physically inside Michigan, verified by geolocation.

The college rule

Michigan is more permissive than most on college betting, for now.

✅ In-state college teams are bettable. You can wager on the Michigan Wolverines and Michigan State Spartans, with no in-state-team or in-state-venue carve-out (unlike New Jersey).
✅ College player props are currently allowed, which puts Michigan in a small minority of states. But this is under active review: after a wave of 2025-2026 college-basketball game-fixing indictments, the MGCB said it is gathering feedback on whether to restrict college props. No ban has been enacted as of mid-2026, but one is plausible, so this is a rule worth re-checking.

Daily fantasy and what is restricted

Traditional daily fantasy sports is legal in Michigan (18+) and regulated by the MGCB. But Michigan is one of the states that banned pick’em-style fantasy: rules that took effect in late 2023 pushed PrizePicks and Underdog out of the paid pick’em market, on the view that those products were sports betting in a fantasy wrapper. Season-long and traditional draft fantasy are unaffected.

Prediction markets: Michigan sued Kalshi

Michigan has been one of the more aggressive states against prediction markets, and it went straight to court.

March 2026: Attorney General Dana Nessel sued Kalshi in state court, alleging its sports-event contracts violate the Lawful Sports Betting Act. Michigan was only the second state to sue Kalshi without first sending a cease-and-desist.
June 29, 2026: a judge granted a temporary restraining order requiring Kalshi to geofence Michigan out and stop offering sports contracts to residents, with fines of up to $120,000 per day for noncompliance. The order pointed to Kalshi letting 18-year-olds wager against Michigan’s 21+ rule and the “irreparable harm” to young people.
July 2026: after that two-week order expired on July 13, Judge Aquilina extended the restraining order with no set expiration date. Kalshi had until August 12, 2026 to block Michigan users (by geofence or by address), with the penalty rising to $500,000 per day from August 13 if it did not comply. That deadline has now passed, and as of August 13, 2026 no compliance finding or sanction had been reported. The judge again called the contracts gambling, not commodities, and told Kalshi to show steady progress rather than wait until the deadline.
July 14, 2026: the federal regulator pushed back, and Michigan became the sharpest state-versus-federal collision in the country. The CFTC stayed an emergency rule change by Kalshi and invoked its emergency authority to order Kalshi to honor already-executed trades, acting expressly “in response to a Michigan state court order directing the company to cancel certain previously executed trades involving Michigan residents.” CFTC Chairman Michael Selig: “A state cannot force a DCM to violate its obligations… The Commission will not allow states or state courts to bully registered entities into violating the Commodity Exchange Act.”

That last step is worth sitting with, because it is not the usual “state versus platform” story. A state judge has ordered Kalshi to cancel Michigan residents’ trades, and the federal regulator has ordered it to honor them. Kalshi is now under two directly conflicting orders from two different governments, and Michigan is where that collision is sharpest. Nothing has resolved it yet.

Kalshi (with Polymarket, Robinhood, and Coinbase) is also fighting Michigan in federal court, arguing federal commodities law preempts state gambling rules. That is the same fight playing out nationally, and Michigan lands on the enforcement side of it. Note that Michigan’s own Kalshi fight is in state court, so Michigan is not one of the cases the Sixth Circuit heard on July 30, 2026; those are Ohio and Tennessee. Nationally, only one federal appeals court has ruled on the preemption question so far: the Third Circuit, for Kalshi, in April 2026, and only at the preliminary-injunction stage, out of the New Jersey case. The appeals courts are not yet split, though a Sixth Circuit ruling against Kalshi would make them so. Offshore sportsbooks, as always, are flatly illegal and unregulated.

The honest 2026 outlook

Michigan’s core framework is stable and mature: 8.4% tax, 21+, MGCB oversight, a dual sports-and-casino market that keeps setting revenue records. The live questions are narrow: whether the MGCB restricts college player props after its review, and how the Kalshi litigation resolves. For a bettor, the practical picture is excellent: legal, deep, low-taxed for a competitive market, and one of the few states where your app can be a sportsbook and a full casino at once.

Is Kalshi legal in Michigan? It is being blocked. Michigan sued Kalshi and a court ordered it to stop offering sports contracts to Michiganders.
