Prediction markets have emerged as one of the fastest-growing sectors in United States trading, but sports contracts and event-based derivatives are increasingly clashing with state gaming laws, federal regulations, and intense competition among exchanges.
Regulatory friction has intensified through several recent legal and legislative actions:
- July 31: New York sued Kalshi in state court, seeking over $36 billion in damages and an injunction to bar the exchange from offering event contracts nationwide.
- August 11: The Commodity Futures Trading Commission (CFTC) invoked emergency authority after Kalshi notified the agency of a market emergency, arguing that federally regulated derivatives markets require national treatment.
- August 12: The New York City Council launched an investigation into the marketing practices of prediction-market firms including Polymarket, Kalshi, Coinbase, and Gemini Titan, reviewing allegations regarding young users, influencer promotions, and misleading advertising.
Meanwhile, CME Group filed a lawsuit against the CFTC challenging the approval of perpetual futures for Kalshi and Coinbase, arguing that the rules create competitive injury by granting rivals access to new products.
The Product-Specific Legal Boundary
Under US law, the CFTC holds authority over designated contract markets, but sports contracts have created a complex overlap with state gambling regulations. In June, the CFTC proposed a new framework for event contracts involving gaming and other activities under the Commodity Exchange Act, which would establish a 90-day review period and assess products case by case.
Judicial rulings across the country remain divided. The Third Circuit ruled in favor of Kalshi in its dispute with New Jersey, finding that federal law preempts the state's efforts to block event contracts. Conversely, judges in Nevada, Maryland, and Ohio permitted state gaming authorities to pursue enforcement actions against Kalshi while underlying legal challenges proceed, while a Tennessee court also ruled in Kalshi's favor.
A key distinction lies in how contracts are utilized. Contracts tied to payroll data, inflation, or commodities function as derivatives used by businesses and investors to manage financial risk. In contrast, sports contracts are typically traded based on game outcomes rather than hedging existing economic exposure.
Retail Protection and Industry Perspectives
Industry executives note that the ongoing disputes encompass both consumer safeguards and commercial competition. Fernando Lillo Aranda, CMO at Zoomex, emphasizes that prediction markets can safeguard retail participants through transparency and education rather than strict access limitations.
"The priority should be transparency, fair market design, and clear risk disclosure. Ultimately, the objective should be to empower users through knowledge rather than limiting innovation," Lillo Aranda stated, noting that markets tied to sports, politics, and weather carry heightened risks of manipulation and emotionally driven trading.
Federico Variola, CEO of Phemex, views the legal battles as a reflection of high-stakes competition between traditional and newer platforms. Controlling access to perpetual futures and event contracts has become exceptionally lucrative, leading established and emerging exchanges to leverage regulation as part of their competitive strategies.
With CME reporting over 100 million trades for its event contracts within eight weeks of launch, and platforms like Coinbase integrating Kalshi products alongside decentralized alternatives like Hyperliquid and Lighter, the intersection of federal oversight, state gaming laws, and exchange rivalry continues to shape the future of the derivatives industry.
