Illinois already licenses sportsbooks, taxes gambling operators, and applies consumer protection rules to the industry. Prediction market platforms, however, remain outside that framework, and State Sen. Michael E. Hastings is pushing to close that gap.
Hastings, a Democrat from Frankfort, is backing Senate Bill 4168, which targets online prediction markets that let users wager on the outcomes of future events. He argues that a company that takes real-money wagers and profits from those bets should not be treated as something separate from gambling in Illinois simply because it uses a different label.
“These platforms are taking real money and allowing users to bet on outcomes just like a sportsbook,” Hastings said in a news release. He added that operators acting like gambling businesses should face the same rules and consumer protections as every other gambling operator in Illinois.
Debate over how to classify prediction markets
Prediction markets have expanded quickly in recent years. They let users buy positions tied to events yet to occur, including elections, sports results, geopolitical flashpoints, and economic developments. Supporters often describe them as forecasting tools or financial products. Critics see something much simpler: a bet dressed up in financial language.
That dispute sits at the center of Hastings’ proposal. Under his bill, platforms that offer speculative contracts on future events could fall within Illinois gambling law when they operate like betting operators. The idea is straightforward: The state would look at the substance of the business, not only the name it uses.
The issue is no longer small or theoretical. The release cites Polymarket as one example of the scale of the business. During the 2024 election cycle, Polymarket processed billions of dollars in trading volume, and some individual markets drew tens of millions in wagers. That scale makes the regulatory question harder to ignore.
Disaster prediction market raises new concerns
Hastings’ argument is not based on volume alone. It also points to the kinds of markets some platforms have allowed, including one especially troubling example.
At one point, users could bet on whether a nuclear weapon would be detonated somewhere in the world. That market drew hundreds of thousands of dollars before it was taken down following public backlash. For Hastings, it was more than bad optics; it showed why the state should not leave this space without clear limits.
That example helps explain the proposal’s tone. This is not just a fight over tax policy or market structure. It is also about where lawmakers think public limits belong. Once real money starts flowing into outcomes on war, disaster, or major political events, the argument for oversight becomes much easier for elected officials to make.
SB 4168: Fees, taxes, and penalties
As introduced, SB 4168 would create the Prediction Markets Regulation and Taxation Act. It states no company may operate a prediction market for Illinois residents without first securing a master prediction market license from the Illinois Gaming Board. The license fee would be $1 million, with an annual renewal fee of $1 million.
The bill proposes an aggressive tax regime alongside its regulatory measures. Under its terms, Illinois would levy a privilege tax equal to half of what qualifying operators earn. The tax will be calculated against adjusted gross revenue from traded contracts involving Illinois residents.
The enforcement piece is just as important. The synopsis says violations could be treated as illegal betting under Illinois law. Penalties could include:
- Cease-and-desist orders
- Civil fines
- License revocation
- Referral for criminal prosecution
The bill was filed March 5, received its first reading the same day, and was referred to the Assignments Committee. Sen. Cristina Castro was later added as a chief co-sponsor.
Closing the regulatory loophole
Hastings is trying to close what he sees as a loophole. Illinois has spent years building a regulated gambling market. Licensed operators must comply with oversight and consumer safeguards. The senator’s position is that prediction-market companies should not be free to reach Illinois users, take their money, and avoid those same obligations.
That does not settle the wider national argument. Companies in this space have often sought to position themselves outside traditional gambling laws. Still, in Springfield, Hastings is making a state-level case that a product’s function matters more than its branding. If a product walks and talks like betting, Illinois may decide to regulate it that way.
For now, the bill is in its early stages. But according to Hastings, the message is already clear. Illinois does not want a parallel wagering market growing in plain sight while the state’s licensed operators follow one set of rules and newer entrants follow another. Hastings is betting there will be enough support to end that split.
