Robinhood Halts New Sports Event Contracts in Michigan on September 9, 2026

Robinhood is set to stop offering new sports-related event contracts to customers in Michigan, adding another major platform to the state's growing dispute over whether sports prediction contracts can operate outside the state's licensed sports-betting framework.

The Michigan Gaming Control Board (MGCB) announced on September 9, 2026, that Robinhood Derivatives, LLC had agreed to stop offering new sports-related event contracts to Michigan customers by the end of Wednesday, September 9.

Robinhood will then have until October 9, 2026, to close out any remaining customer positions.

The agreement is court-approved and comes while litigation over sports-related event contracts continues. Importantly, the agreement does not concede either party's legal position.

The development makes Robinhood the second major sports-contract platform to halt its Michigan offering in 2026, following Kalshi's legal battle with the state.

For Michigan regulators, the Robinhood agreement represents another step toward keeping sports wagering products within the state's licensed and regulated gambling system. For prediction-market operators, however, the dispute is part of a much larger national question over whether federally regulated event contracts can be treated differently from state-regulated sports betting.

The distinction is becoming increasingly important as prediction markets expand rapidly across the United States.

Robinhood Will Stop New Michigan Sports Contracts on September 9

The timeline in the Michigan agreement is straightforward.

September 9, 2026: Robinhood must stop offering new sports-related event contracts to Michigan customers by the end of the day.

October 9, 2026: Robinhood must close out remaining customer positions.

That means the September 9 deadline concerns new contracts, not an immediate liquidation of every existing position.

Customers with remaining positions have an additional 30 days under the agreement to have those positions closed.

The Michigan Gaming Control Board described the arrangement as a court-approved agreement reached amid ongoing litigation.

That detail matters because the agreement is not the same thing as a final judicial determination that Robinhood's contracts are illegal.

Instead, it establishes what Robinhood will do in Michigan while the broader legal dispute continues.

The agreement also does not mean Robinhood has accepted Michigan's underlying legal interpretation.

That distinction could become important as courts consider the larger conflict between federal derivatives regulation and state gambling law.

Michigan Is Now Targeting a Second Prediction-Market Operator

Robinhood's withdrawal follows an earlier action involving Kalshi.

In June 2026, a Michigan judge temporarily blocked Kalshi from offering sports-related event contracts in the state while the legal dispute continued. Reuters reported that the order made Michigan the second state to implement a court-ordered restriction against Kalshi's event contracts, following Nevada.

The MGCB had also previously warned that Kalshi could face penalties for continuing to offer what Michigan regulators considered unlicensed sports wagering products.

The Robinhood development therefore does not appear in isolation.

Michigan has now taken action involving two prominent prediction-market platforms offering sports-related contracts in the state.

That creates an increasingly clear regulatory pattern.

The state is arguing that sports-related event contracts should be offered through operators that are licensed and regulated under Michigan law.

Prediction-market companies, meanwhile, have generally maintained that their contracts fall under federal derivatives regulation rather than state sports-betting rules.

That disagreement is at the center of the legal battle.

Why Michigan Is Challenging Sports Prediction Markets

The dispute comes down to how sports event contracts are classified.

Traditional sports betting in Michigan operates under a state-regulated framework. Licensed operators must follow the state's rules governing sports wagering, including requirements designed around consumer protection, responsible gambling and regulatory oversight.

Prediction-market operators take a different approach.

Their sports contracts are structured as event contracts and are offered through federally regulated derivatives infrastructure.

That distinction has allowed prediction-market platforms to expand sports-related trading in jurisdictions where traditional online sportsbooks face different state-level restrictions.

Michigan regulators are challenging that distinction.

The MGCB's position, as reflected in the September 9 announcement, is that sports wagering products should only be offered by operators that are licensed and regulated under Michigan law.

The board's executive director, Henry Williams, described the Robinhood agreement as a consumer-protection measure and said Michigan would continue working with the Attorney General's Office while courts address the broader legal questions.

The disagreement is therefore bigger than Robinhood.

It concerns which regulator has authority over sports-related event contracts and which legal framework should govern them.

Robinhood's Michigan Agreement Does Not Settle the Legal Question

One of the most important details in the September 9 announcement is what the agreement does not do.

It does not settle the broader legal question.

The agreement does not concede the legal position of Michigan regulators.

It also does not necessarily establish a nationwide precedent for Robinhood's prediction-market business.

Instead, it resolves the immediate issue of Robinhood's sports-related contracts in Michigan while litigation continues.

That distinction is worth emphasizing because prediction-market regulation remains unsettled across several states.

A temporary restriction, settlement or agreement in one state does not automatically determine whether the same contracts are lawful elsewhere.

The legal arguments can also differ depending on the precise contracts being offered, the exchange involved and the state's gaming laws.

For Robinhood, the practical result is nevertheless clear.

Michigan customers will no longer be able to open new sports-related event-contract positions after September 9, 2026.

October 9 Is the Key Date for Existing Positions

While September 9 is the immediate headline date, October 9, 2026 is also important.

Robinhood has agreed to close out remaining customer positions by that date.

This gives existing customers a 30-day period between the announcement's deadline for new contracts and the final closeout deadline.

The distinction could matter to traders who already hold positions tied to sporting events.

A platform stopping new contracts does not necessarily mean every existing contract disappears immediately.

The court-approved agreement instead provides a transition period for outstanding positions.

From a market perspective, that also means Michigan's Robinhood sports-contract activity will not necessarily go from normal operation to zero in a single moment.

The September 9 deadline begins the withdrawal.

October 9 is the scheduled endpoint for remaining customer positions.

Robinhood's Exit Comes as Prediction Markets Expand

The Michigan dispute is unfolding at a particularly important time for the prediction-market industry.

Prediction markets have experienced substantial growth during 2026, particularly in sports.

Recent data from The PM Scoreboard showed that the top CFTC-regulated exchanges generated $13.9 billion in combined volume from September 1 through September 7, 2026.

Kalshi alone accounted for $11.8 billion during that seven-day period.

Sports were a major contributor, with college football activity rising sharply as the season began.

DKeX, DraftKings' prediction-market exchange, recorded $226 million in weekly volume, up 609.9%.

The timing is significant.

The Robinhood-Michigan agreement was announced on September 9, the same day the 2026 NFL season was beginning.

That means the legal dispute is unfolding just as sports prediction markets are entering one of their busiest periods of the year.

The NFL season could bring another substantial increase in event-contract activity, creating even more attention around the question of how these products should be regulated.

Michigan's Kalshi and Robinhood Actions Could Have Wider Implications

Michigan is only one part of a much larger regulatory debate.

The state-level disputes involving prediction markets are increasingly colliding with the federal regulatory framework.

Reuters reported on September 8 that Robinhood was expanding its prediction-market strategy through a partnership with OG.com, a derivatives exchange and clearinghouse spun out of Crypto(.com). Robinhood said it would route some football event contracts through OG.com's federally regulated exchange.

That development makes the Michigan situation particularly interesting.

Robinhood is simultaneously expanding its prediction-market infrastructure while agreeing to pull new sports-related contracts from Michigan.

In other words, the company's overall prediction-market strategy is not disappearing.

The business is becoming more sophisticated, while state-level restrictions are forcing operators to navigate a complicated regulatory map.

That could lead to an increasingly fragmented market in which the same sports contract is available to customers in one state but unavailable in another.

The Michigan Dispute Comes Down to State Versus Federal Authority

At the heart of the issue is a fundamental regulatory question.

Who gets to regulate sports event contracts?

Michigan argues that sports wagering offered to Michigan residents should fall under Michigan's gaming laws.

Prediction-market companies argue that their event contracts are derivatives subject to federal oversight.

That conflict has consequences well beyond Michigan.

If state regulators prevail broadly, prediction-market companies could face significant restrictions on sports contracts across the country.

If federal authority prevails, state regulators could have less ability to prevent federally regulated exchanges from offering sports-related event contracts to residents.

The outcome could reshape the competitive relationship between prediction markets and traditional sportsbooks.

It could also determine whether companies such as Robinhood, Kalshi and other exchanges can continue offering sports contracts nationally through federally regulated infrastructure.

Robinhood Is Not Leaving Prediction Markets

It would be misleading to describe the September 9 agreement as Robinhood abandoning prediction markets.

The company continues to invest in the sector.

On September 8, Robinhood announced an expanded prediction-market arrangement involving Crypto(.com) and OG.com, with some football event-contract volume expected to be routed through OG.com's federally regulated exchange.

The move shows that Robinhood is looking for additional infrastructure and exchange relationships as its prediction-market business grows.

That makes the Michigan withdrawal more specific.

Robinhood is stepping back from offering new sports-related event contracts to Michigan customers. It is not stepping back from prediction markets as a whole.

That distinction is critical.

What Happens to Robinhood Sports Contracts in Michigan?

For Michigan customers, the immediate timeline is clear:

The agreement does not resolve the broader legal dispute.

Instead, it provides a temporary operational resolution while the courts continue to address the underlying questions.

For traders, the most important point is therefore simple: new Robinhood sports event contracts will no longer be available to Michigan customers after September 9, 2026.

What the Robinhood-Michigan Agreement Means for Prediction Markets

The September 9 agreement is another sign that the rapid growth of sports prediction markets is running directly into state gambling regulation.

Michigan has now taken action against two major platforms offering sports-related event contracts: Kalshi and Robinhood.

The state wants sports wagering products to remain within its licensed regulatory framework.

Prediction-market operators are relying on a different legal argument based on federal derivatives regulation.

Neither side's position is settled by the Robinhood agreement.

That is perhaps the most important point.

Robinhood's September 9 withdrawal from new Michigan sports contracts resolves an immediate operational dispute, but it does not resolve the national fight over who has the authority to regulate sports prediction markets.

With the NFL season beginning on September 9, 2026, the timing could hardly be more significant.

Sports event-contract volume is growing rapidly at the same moment regulators are increasing scrutiny.

Michigan's next steps, the ongoing Kalshi litigation and future court decisions could therefore become important markers for the entire U.S. prediction-market industry.

For now, the dates are clear.

September 9, 2026: new Robinhood sports contracts stop in Michigan.

October 9, 2026: remaining positions are scheduled to be closed.
