The landscape of American prediction markets faces fresh uncertainty following a Maryland federal court’s rejection of Kalshi’s motion for preliminary injunction, marking the platform’s first significant legal setback in its battle against state regulators. Judge Adam Abelson’s Friday ruling diverged from favorable decisions in Nevada and New Jersey, creating a complex patchwork of jurisdictional authority that could reshape how prediction markets operate nationwide.
Maryland’s dispute with Kalshi centers on fundamental questions about the nature of sports-based prediction contracts and whether federal oversight preempts state gambling regulation. The Maryland Lottery and Gaming Commission issued a cease-and-desist letter in April, arguing that Kalshi’s sports outcome contracts constitute unregulated sports betting under state law. Kalshi maintains these products are federally regulated derivatives, not gambling instruments, falling exclusively under Commodity Futures Trading Commission jurisdiction.
Maryland’s Unique Gambling Evolution Creates Complex Regulatory Environment
Maryland’s current stance on prediction markets emerges from a fascinating gambling history that spans from prohibition to progressive legalization. The state experienced dramatic swings in its gambling landscape, from hosting thousands of slot machines in Southern Maryland during the 1940s and 1950s to complete prohibition by 1968. This historical context informs current regulatory approaches, with officials exercising caution about new forms of gambling that might circumvent established oversight mechanisms.
The modern Maryland gambling framework began taking shape in 2008 with casino authorization, followed by sports betting legalization in 2021. Voters approved sports betting with overwhelming 67% support in 2020, demonstrating public appetite for wagering options. However, the state’s regulatory structure reflects hard-learned lessons from past gambling controversies, emphasizing comprehensive oversight and tribal gaming protections.
Maryland’s sports betting market has generated substantial revenue since launching, with handle reaching $377.3 million in August 2024 alone, representing a 30% year-over-year increase. The state collected over $143 million in combined tax revenue from retail and online sports betting since operations began. This success has made regulators particularly protective of their oversight authority, viewing unauthorized gambling operations as threats to both tax revenue and consumer protection frameworks.
Interestingly, Maryland lawmakers have also shown ambivalence about expanding gambling options. Senator Joanne Benson filed Senate Bill 1033 in 2025, proposing to eliminate online sports betting entirely while maintaining retail operations. This legislative tension reflects ongoing debates about gambling’s social costs versus economic benefits.
Kalshi’s Revolutionary Approach to Event Prediction
Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi represents a fundamental shift in how Americans can engage with prediction markets. The platform operates as a federally regulated exchange under CFTC oversight, offering “event contracts” on everything from political outcomes to weather patterns. Unlike traditional sportsbooks that rely on house edges, Kalshi facilitates peer-to-peer trading where users buy and sell positions based on yes-or-no questions about future events.
The platform’s regulatory foundation distinguishes it from competitors. As the first CFTC-designated contract market exclusively for event contracts, Kalshi argues it operates under federal derivatives law rather than state gambling regulations. This positioning has allowed the company to offer services in all 50 states, contrasting sharply with traditional sportsbooks that must secure individual state licenses.
Kalshi’s business model centers on transaction fees rather than betting margins, typically charging 7% of expected earnings per contract. Users can trade contracts priced between $0.01 and $0.99, with winning positions paying $1.00. This structure creates a stock market-like environment where users can buy, sell, or hold positions based on changing probability assessments.
The platform has experienced remarkable growth, achieving a $2 billion valuation in June 2025 through a $185 million funding round. Trading volume has expanded dramatically, particularly during major political events. The 2024 presidential election saw over $3 million traded within days of Kalshi’s congressional control contracts launching, demonstrating significant market appetite for political prediction trading.
Recent strategic moves include hiring Donald Trump Jr. as an advisor in January 2025, though the relationship with Trump administration officials has proven complex. Kalshi’s former chief legal officer, Eliezer Mishory, departed to lead the Securities and Exchange Commission’s Government Efficiency unit, creating interesting regulatory dynamics as the platform faces scrutiny from federal and state authorities.
Contrasting Regulatory Approaches in Other States
The divergent outcomes in Nevada, New Jersey, and Maryland illustrate the complex legal terrain surrounding prediction markets. Federal judges in Nevada and New Jersey granted Kalshi preliminary injunctions, finding that the Commodity Exchange Act likely preempts state gambling regulation of CFTC-registered exchanges. These courts emphasized federal exclusive jurisdiction over derivatives trading, viewing state enforcement efforts as impermissible interference with congressional regulatory schemes.
Nevada’s gaming regulators had issued cease-and-desist orders similar to Maryland’s, arguing that Kalshi’s sports contracts violated state law. However, U.S. District Judge Andrew Gordon ruled in April that Kalshi would likely succeed on its preemption claims, allowing continued operations pending litigation resolution. The decision emphasized that forcing Kalshi to comply with patchwork state regulations would undermine federal regulatory uniformity that Congress intended when establishing CFTC authority.
New Jersey’s federal court reached similar conclusions, with Judge Edward Kiel granting preliminary injunctive relief after finding Kalshi’s sports contracts fell within exclusive federal jurisdiction. The court noted potential irreparable harm from state enforcement, including lost business relationships and operational difficulties from state-by-state compliance requirements.
Maryland’s Judge Abelson took a notably different approach, emphasizing presumptions against federal preemption and recognizing states’ longstanding authority over gambling regulation. The ruling highlighted Congress’s specific exclusion of certain activities from CFTC jurisdiction, suggesting that sports-related contracts might fall outside federal derivatives authority. This interpretation creates potential circuit splits that could ultimately require Supreme Court resolution.
Tribal Gaming Concerns Add Complexity
Maryland’s unique position includes significant tribal gaming interests, with 27 federally recognized tribes filing amicus briefs supporting state regulatory authority. These tribal entities argue that Kalshi’s operations threaten Class III gaming compacts that provide exclusive territorial rights for casino-style gambling on tribal lands. Under the Indian Gaming Regulatory Act, sports betting constitutes Class III gaming requiring tribal-state compacts, making unauthorized sports wagering particularly sensitive to tribal sovereignty concerns.
The tribal intervention reflects broader concerns about prediction markets undermining carefully negotiated gaming agreements. Tribes invested heavily in developing gaming infrastructure based on exclusivity arrangements with states, and the emergence of federally regulated prediction markets offering similar products threatens these economic foundations. Tribal gaming revenue supports essential government services and economic development on reservations, making regulatory certainty crucial for long-term planning.
Coalition briefs from tribal organizations emphasize that Kalshi’s federal regulatory status doesn’t automatically preempt tribal gaming rights. The Indian Gaming Regulatory Act contains specific provisions protecting tribal gaming exclusivity, and tribes argue that allowing prediction markets to operate without state oversight could effectively circumvent these protections. This creates a three-way jurisdictional tension between federal commodities regulation, state gambling oversight, and tribal gaming sovereignty.
The Broader Prediction Market Ecosystem
Kalshi operates within a rapidly evolving prediction market landscape that includes several distinct platforms serving different regulatory and geographic niches. PredictIt, the longest-operating U.S. political prediction market, operated under CFTC no-action letters from 2014 until 2022, when regulatory support was withdrawn. The platform focused exclusively on political events with strict betting limits of $850 per user per market, reflecting its academic research origins through Victoria University of Wellington partnership.
Polymarket represents the decentralized alternative, operating on blockchain technology and accepting users globally except from the United States. Built on Polygon blockchain using USDC stablecoin, Polymarket offers broader event coverage than regulated alternatives but faces regulatory uncertainty. The platform gained prominence during the 2024 election cycle, handling nearly $3 billion in total volume, though questions persist about market manipulation and the legitimacy of large individual positions.
The regulatory fragmentation creates interesting arbitrage opportunities and market inefficiencies. PredictIt typically shows different odds than Polymarket for similar events, partly due to regulatory constraints limiting sophisticated trading. Kalshi’s full regulatory approval allows higher position limits and institutional participation, potentially creating more efficient price discovery mechanisms.
Academic research consistently demonstrates prediction markets’ forecasting accuracy advantages over traditional polling methods. The Iowa Electronic Markets, operating since 1988, have shown superior election prediction accuracy compared to polls, particularly in longer-term forecasting. This track record supports arguments for prediction markets’ public benefit, though regulatory authorities remain concerned about gambling-related social costs.
Market Statistics and Economic Impact
The prediction market sector represents a small but growing segment of the broader gambling industry. While comprehensive statistics remain limited due to regulatory fragmentation, available data suggests significant expansion potential. Kalshi’s $2 billion valuation reflects investor confidence in prediction markets’ commercial viability, though the platform must navigate complex regulatory challenges to realize this potential.
U.S. sports betting markets provide context for prediction market growth possibilities. Legal sports betting generated $13.71 billion in operator revenue during 2024, up from $11.04 billion in 2023, according to American Gaming Association data. This 24% growth rate demonstrates consumer appetite for event-based wagering, though traditional sports betting operates under established state regulatory frameworks that prediction markets currently challenge.
The broader online gambling market reached $78.66 billion globally in 2024 and projects growth reaching $153.57 billion by 2030. A significant part of it is constituted by crypto gambling platforms. Prediction markets could capture meaningful market share if regulatory uncertainties resolve favorably, particularly given their unique positioning between financial derivatives and entertainment gambling.
Commercial gaming revenue tracker data shows sports betting represents an increasingly important segment, generating 30% of all commercial gaming revenue from digital sources in 2024 compared to 13% in 2021. This digital shift favors platforms like Kalshi that operate primarily through mobile applications and web interfaces.
What’s Next for the Industry
The Maryland ruling’s implications extend beyond Kalshi’s immediate operational concerns, potentially influencing how federal and state authorities approach emerging financial technologies that blur traditional regulatory boundaries. If appellate courts uphold Maryland’s position, prediction markets may face fragmented state-by-state regulation similar to traditional gambling industries. Conversely, if federal preemption arguments ultimately prevail, it could open broader opportunities for CFTC-regulated prediction platforms.
The developing circuit split between district courts suggests eventual Supreme Court involvement may be necessary to resolve fundamental questions about federal versus state authority over prediction markets. Such a ruling could establish clearer boundaries between financial derivatives and gambling activities, providing regulatory certainty that both prediction market operators and state gambling regulators desperately need.
Industry observers note that prediction markets’ success depends heavily on liquidity and user confidence, both of which suffer from regulatory uncertainty. Kalshi’s ability to continue operations in contested states while litigation proceeds helps maintain market functionality, but prolonged legal battles could discourage institutional participation and limit platform growth.
The prediction market evolution occurs alongside broader trends toward real-time, data-driven entertainment that appeals particularly to younger demographics comfortable with mobile-first experiences. This generational shift suggests continued demand for prediction market products regardless of current regulatory challenges, though the specific platforms and structures may evolve significantly based on legal outcomes.
