Michigan Online Gambling Regulation, Licensing & Tax Regime

This period's dominant development in Michigan is continued enforcement by the Gaming Control Board and the Attorney General against prediction-market platforms offering sports-related event contracts, a product category the state treats as unlicensed internet sports betting under the Lawful Sports Betting Act rather than a lawful, federally preempted commodities product. Coinbase Financial Markets, Inc. and Polymarket US (QCX LLC) both entered stipulations with the Board to exit this product line in Michigan, following earlier exits by other platforms, while KalshiEx, LLC faces a motion for civil contempt and a hearing set for 24 November 2026 over alleged continued advertising in violation of a preliminary injunction. Separately, the Board issued cease-and-desist letters to thirty-three offshore operators offering unlicensed online casino and sports betting products. The established, licensed commercial and tribal gaming market continues to operate under the existing statutory framework, unaffected by this enforcement wave, which is concentrated specifically on the prediction-market and offshore-operator segments.

Michigan's licensing framework for internet gaming and sports betting operates under the Lawful Internet Gaming Act (LIGA), a durable statutory instrument administered by the Michigan Gaming Control Board through a fixed fifteen-licence structure: three commercial licences and twelve tribal licences. This cap is confirmed fully allocated as of 2025, meaning the licensing framework itself is closed to fresh direct grants; the Board's role has shifted from allocating new licences to administering the existing fifteen. The Board's own leadership is presently in transition: James Townsend has been appointed MGCB chair, though the appointment remains pending a Michigan Senate confirmation vote, and no new licensing determination was identified this cycle. This appointment finding carries only Low confidence, reflecting reliance on a single T3 trade-press source with no Senate vote occurring within the reporting window. Operators should treat the licensing framework as stable in structure but closed in capacity, with the chair transition an administrative variable to monitor rather than a substantive licensing-policy shift.

iGaming AGR is taxed on a graduated scale of 20%–28%, with the top tier reserved for operators grossing over $12M/month. Online sports wagering is taxed at 8.4% of AGR. Detroit commercial casinos pay an additional 1.25% municipal services fee. Free-play deductibility tapers over the first five operating years.

Kalshi's GeoComply-based geofencing implementation is the principal technical-compliance development bearing on Michigan this cycle, though it is enforced via the Ingham Circuit Court's temporary restraining order in Nessel v. Kalshi rather than through a standing certification regime. Kalshi met the court's August 12, 2026 compliance deadline, avoiding a threatened $500,000-per-day fine, an outcome carrying Assessed confidence corroborated by two independent Gambling Insider articles, though no direct Michigan Gaming Control Board statement or court-filing text was retrieved this cycle. No other technical-certification development, such as RNG certification or server-location rules, was identified this cycle. The geofencing requirement is presently specific to Kalshi's prediction-market product rather than a codified technical standard applicable to all licensed operators, but it demonstrates that Michigan courts are willing to impose specific, technically defined compliance obligations as an enforcement remedy.

The Michigan Gaming Control Board secured a stipulation with Coinbase Financial Markets, Inc., requiring the company to stop offering new sports-related event contracts to Michigan customers and wind down open positions, and a comparable federal-court-approved stipulation with Polymarket US (QCX LLC), requiring cessation of new contracts and closure of all open Michigan positions by a fixed deadline; Polymarket is reported as the fourth operator to exit this product line in the state. Both actions proceed under the Board's position that such contracts constitute internet sports betting requiring licensure under the Lawful Sports Betting Act. The Michigan Attorney General separately moved to hold KalshiEx, LLC in civil contempt, alleging continued advertising of sports-related event contracts to Michigan residents in violation of a preliminary injunction, with a proposed noncompliance fine of $500,000 per day and a hearing set for 24 November 2026; this follows the Attorney General's earlier temporary restraining order against Kalshi in the Ingham County Circuit Court. In a parallel but distinct track, the Board issued cease-and-desist letters to thirty-three offshore operators found to be illegally offering unlicensed online casino games, sweepstakes-style games, or sports betting to Michigan residents, noting that licensed Michigan operators, unlike these offshore sites, must honor the state's Responsible Gaming Database self-exclusion scheme. Together these four actions indicate an active, escalating enforcement programme against both the prediction-market product category and the offshore unlicensed sector.

Michigan's online market continues record growth, prompting an MGCB regulatory review in December 2025 covering licensing, compliance and enforcement. Legislative proposals to adjust the top operator tax tier have been floated but not enacted. Direction is mixed: strong commercial momentum alongside potential tightening of rules and tax.
