Michigan regulators just made their stance crystal clear: state-licensed sportsbooks and casinos should steer clear of prediction markets — or risk their licenses.
The Michigan Gaming Control Board (MGCB) sent a strongly worded memo to operators across the state, warning that even indirect involvement in these emerging “sporting event contracts” could have serious consequences.
The move puts Michigan in line with a growing number of states that are cracking down on this gray area of betting, where trading markets for sports and politics are blurring the line between Wall Street and sportsbooks.
What Exactly Are Prediction Markets?
Prediction market sites, such as Kalshi, Polymarket, and Robinhood Markets, allow users to trade “event contracts” that function much like bets on real-world outcomes.
Instead of betting $20 on the Lions to win, users might buy shares in a “Yes” contract priced at 55 cents, which pays $1 if the outcome happens. If you think the market’s wrong, you can sell or trade your position before the event ends.
In theory, these are financial instruments regulated by the Commodity Futures Trading Commission (CFTC) rather than gambling authorities. In practice, they often mirror sports wagers, just with different terminology.
That distinction with online sports betting hasn’t stopped state regulators from raising eyebrows. Michigan’s letter indicates that while prediction markets may operate under federal law, state gambling boards aren’t comfortable with licensed gaming operators entering this new space.
The MGCB’s Warning: “Stay Away or Risk Your License”
The memo, signed by MGCB Executive Director Henry Williams, was sent to every commercial casino, online operator, and supplier in Michigan. The message left little room for interpretation.
“The MGCB writes to make you aware that any involvement in the offering of sporting event contracts, directly or via an affiliate, key person, related business entity, or other association, will have implications relative to your licensure in Michigan,” the letter stated.
That covers just about everything — from partnering with a company that runs prediction markets, to offering access to those markets through an app, to even doing business in another state where such contracts have faced regulatory objections.
The MGCB made it clear this isn’t just about what operators do inside Michigan’s borders. Conduct elsewhere could still reflect on their “suitability for licensure.”
In other words, if you’re a Michigan sportsbook or casino, don’t even think about it.
What’s Driving the Crackdown?
The heart of Michigan’s concern is oversight. Prediction markets aren’t licensed or taxed by the state. They fall under a different regulatory regime that wasn’t designed for gambling. That leaves questions about consumer protection, tax fairness, and accountability.
The MGCB’s letter also noted that it had recently issued six cease-and-desist letters to unlicensed gambling sites earlier in the week — part of a broader effort to clean up the state’s online gaming environment.
Williams and his team have demonstrated a willingness to take strong action when they believe operators are deviating from established guidelines.
Michigan was one of the earliest states to legalize both online casinos and sports betting, and the MGCB takes pride in maintaining a tightly regulated ecosystem.
“Each licensee is under an ongoing duty to notify the MGCB of any material change in licensing information, or any change in circumstance that is relevant to a licensee’s suitability,” the memo read. “Accordingly, the MGCB expects any licensee that is actively pursuing any involvement in the offering of sporting event contracts to provide prompt notice to the MGCB.”
That’s regulator-speak for: don’t surprise us.
The National Context: Other States Are Watching
Michigan isn’t alone in its skepticism. Over the past two months, Ohio and Arizona have issued similar warnings.
In August, the Ohio Casino Control Commission (OCCC) sent letters to its sportsbooks saying that any connection to prediction markets could jeopardize their licenses.
A few weeks later, the Arizona Department of Gaming echoed that message, warning operators that even partnerships with companies involved in prediction markets could violate their suitability requirements.
Now Michigan — the first state with both iGaming and sports betting — has added its voice to the chorus. That’s significant because its stance could influence how other full-service gambling states, like Pennsylvania and New Jersey, handle the issue.
The CFTC hasn’t helped clarify things. The federal regulator recently issued its own advisory, warning prediction markets that the agency “has not, to date, taken any official action to approve the listing for trading of sports-related event contracts.”
Translation: these platforms are operating in a legal gray area, and the federal regulator doesn’t want to be seen as endorsing them.
Big Names Are Already Exploring the Space
Despite the uncertainty, several major operators are already testing the waters.
FanDuel, for example, is reportedly developing a FanDuel Markets platform in partnership with CME Group, one of the world’s largest financial exchanges.
DraftKings and Fanatics have both filed paperwork with the National Futures Association (NFA) — an early step toward launching their own versions of event-based trading.
Meanwhile, Underdog Fantasy has entered into an agreement with Crypto.com to facilitate sports contract trading in some states, and PrizePicks recently received NFA approval to operate as a Futures Commission Merchant.
Several of those companies already operate licensed fantasy or sportsbook platforms in Michigan. That’s why the MGCB’s warning is so noteworthy — it’s effectively telling some of the biggest names in the business to hit pause.
Why This Matters for Michigan Players
For everyday Michigan bettors, the memo doesn’t change much — at least for now. You can still wager at licensed sportsbooks, play online casino games, or enter fantasy contests.
Prediction markets, such as Kalshi and Polymarket, remain accessible in Michigan, as they operate under federal oversight.
The bigger story is about where the lines get drawn between finance and gambling. If prediction markets continue to grow — and if companies like DraftKings or FanDuel eventually launch their own — regulators will have to decide how those products fit within existing laws.
Michigan’s warning shows that the state wants to stay ahead of that curve. Its message to operators is clear: if you want to play in Michigan’s sandbox, you’ll follow Michigan’s rules.
