The Gambling Wire: A Comprehensive Guide to Prediction Markets Regulation

Introduction

Prediction markets—platforms where users trade contracts based on event outcomes such as sports games, elections, or financial indicators—occupy a contentious regulatory space between gambling and financial derivatives. Recent legal developments have intensified this ambiguity. A federal judge in Illinois delivered a rare courtroom victory for these markets, while Ohio regulators simultaneously escalated enforcement. This guide expands on the original article’s skeleton, providing deeper context, legal analysis, market implications, and a global regulatory overview. It is designed for readers seeking a thorough understanding of the issues, from legal professionals to industry participants.

The Landmark Illinois Ruling: A Win for Prediction Markets

Background and Parties Involved

The case involved Kalshi—a platform specializing in event-based contracts—alongside Coinbase and the Commodity Futures Trading Commission (CFTC), against state regulators from Illinois. At issue was whether Kalshi’s sports‑event contracts qualify as “swaps” under the Commodity Exchange Act (CEA) and whether Illinois gambling laws are preempted by federal law.

Judge’s Reasoning: Swaps Definition

U.S. District Judge Martha Pacold found that Kalshi’s core sports contracts are likely swaps under the CEA. The CEA defines swaps in part as contracts dependent on “the occurrence, nonoccurrence, or the extent of the occurrence” of an event. Judge Pacold rejected a narrower interpretation used in other litigation that distinguished between a sporting event and its outcome. She reasoned that if “occurrence” and “nonoccurrence” address whether an event happens, then “the extent of the occurrence” can reach how an event resolves. This reading aligns well with prediction-market mechanics.

Preemption and the “Impartial Access” Argument

Judge Pacold granted the plaintiffs’ request for a preliminary injunction, concluding that several Illinois laws regulating sports‑event contracts likely conflict with federal law. A key point was the “impartial access” argument: Illinois would require Kalshi to impose age and geographic restrictions, effectively determining who could participate in a federally regulated market. The court noted these requirements may conflict with CFTC rules, indicating that state‑level restrictions cannot interfere with federal market supervision.

The Fee Question

The court addressed Illinois’ wagering fees but did not rule definitively on preemption. Judge Pacold stated that states can generally impose costs on federally regulated activity without automatically creating a conflict—meaning Illinois might still tax prediction‑market transactions. However, she warned that “what defendants cannot do overtly, they cannot do covertly.” The fee question remains open for further briefing if the charges effectively regulate or restrict trading rather than merely raise revenue.

Significance and Split with Other Circuits

This decision contrasts sharply with the Sixth Circuit’s September 25 ruling siding with Ohio and Tennessee. It also creates a district‑court split within the Seventh Circuit: a federal judge in Wisconsin previously sided with state regulators against the CFTC. The Illinois ruling thus strengthens the legal foundation for prediction markets in the Seventh Circuit while highlighting the inconsistency that may eventually prompt Supreme Court review.

Ohio’s Coordinated Enforcement After Sixth Circuit Win

Cease‑and‑Desist Notices

On October 2, the Ohio Casino Control Commission issued cease‑and‑desist notices to ten companies: Underdog, Gemini, Coinbase, ProphetX, Novig, Polymarket, Plus500, Moomoo, and Webull. A separate earlier notice against Robinhood was reasserted. The commission alleges these entities offer or facilitate unlicensed sports betting in Ohio.

Ohio repeatedly cited the Sixth Circuit’s decision that the sports contracts in question are not swaps under the CEA and that federal law does not preempt Ohio’s sports wagering laws. The notices extend not only to operators but also to firms that solicit or accept orders as futures commission merchants, broadening the enforcement net.

Compliance Timeline

Recipients were given 14 days to confirm compliance, meaning they must either cease offering sports‑event contracts to Ohio customers or risk further legal action. This quick deadline underscores the state’s determination to act on its appellate victory.

Political Fallout: Becerra Returns Contributions from Prediction Markets

What Happened

California gubernatorial candidate Xavier Becerra’s latest campaign finance filing shows he refunded maximum contributions from Kalshi ($39,200) and Underdog Sports Holdings ($50,000). Gaming attorney Daniel Wallach highlighted this on social media, raising questions about whether Becerra is distancing himself from prediction markets.

Context

The contributions had drawn scrutiny when made before California’s June primary, because Kalshi was simultaneously offering contracts on the gubernatorial election—giving Becerra a 74% chance of winning. Returning the donations could be a strategic move to avoid the appearance of a conflict of interest or to sidestep controversy as regulation heats up.

Broader Implications

This event illustrates how the legal uncertainty surrounding prediction markets spills over into politics and campaign finance. Candidates may increasingly choose to refuse or return contributions from these platforms to avoid reputational or legal risks.

Competitive Dynamics: Fanatics Plans Major Spending Increase

The Spending Surge

Michael Rubin, CEO of Fanatics, told Bloomberg the company could spend $800 million to $1 billion on betting and gaming advertising in 2027—up from roughly $350 million in 2023. This would be a major escalation as Fanatics attempts to close the gap with industry leaders FanDuel and DraftKings.

Market Position

Fanatics derives about $2 billion of its $14 billion in revenue from sports betting, holding roughly 10% of the U.S. market since launching online wagering in 2023. Rubin emphasized that Fanatics’ private status gives it flexibility compared to publicly traded rivals like DraftKings and Flutter.

Regulatory Outlook

Rubin acknowledged that the regulatory environment is unlikely to stay the same, predicting a “very tough road ahead” for both traditional betting firms and prediction platforms such as Kalshi and Polymarket. His comments signal that industry players are bracing for heightened scrutiny.

International Regulation: Brazil’s Betting Ban Gains Amendments

Legislative Process

Brazil’s proposed ban on online betting has drawn 42 proposed amendments in Congress, with four subsequently withdrawn. The provisional measure must be approved to become permanent, and lawmakers have until October 13 to file amendments.

Amendment Types

This patchwork approach reflects the difficulty lawmakers face in balancing consumer protection, tax revenue, and industry interests.

Social and Ethical Dimensions: Mormon Church Condemns Gambling

Statement from Leadership

D. Todd Christofferson, one of the top three leaders of the Church of Jesus Christ of Latter-day Saints, used the church’s semiannual general conference to criticize the spread of online gambling and prediction markets. He warned that they foster greed, especially among younger people, and declared that “gambling is morally wrong – built on the desire to obtain something for nothing.”

Context in Utah

Utah prohibits all forms of gambling, and a federal judge in the state ruled in August against Kalshi, rejecting its effort to block enforcement of Utah’s gambling laws. The church’s statement adds a powerful moral voice to the regulatory opposition, potentially influencing both public opinion and legislative action in Utah and beyond.

Industry Partnership: NFL and theScore Bet Canada

Deal Details

The NFL and PENN Entertainment’s theScore Bet announced a multi‑year partnership covering theScore Bet’s Canadian business. The agreement grants theScore Bet access to NFL trademarks, marketing rights, and league intellectual property, including around major events like the NFL Draft and the Super Bowl. It extends across theScore Bet, theScore Casino, and Hollywood Casino.

Strategic Context

This partnership follows theScore Bet’s expansion into Alberta and a separate deal with the Canadian Football League. It signals the growing integration of sportsbook operators with official league properties, a trend that may intensify as legal sports betting expands in Canada.

Developments to Watch in the Coming Weeks

Market Volume

Prediction market volume continues to set records, with two consecutive record‑setting football weekends. Key questions include whether Sunday volume can break another record and how smaller platforms are performing relative to giants like Kalshi and Polymarket.

Oral arguments are scheduled in the CFTC lawsuit against Kentucky, which could further shape the legal landscape. The growing list of state and federal cases suggests that a definitive Supreme Court ruling may eventually be needed to resolve the regulatory clash.

Regulatory Coordination

State regulators are sharing information and strategies, as seen in Ohio’s coordinated notices. Federal agencies, including the CFTC and SEC, may also weigh in with new rulemakings or enforcement actions.

Conclusion

The prediction markets sector stands at a crossroads. The Illinois ruling provides a powerful legal precedent for treating event‑based contracts as federally regulated swaps, while Ohio’s actions demonstrate continued state-level resistance. Political, ethical, and international developments add further complexity. Stakeholders—from platforms and investors to regulators and consumers—should closely monitor these evolving dynamics, as the choices made in the coming months will shape the future of this contentious industry.
