Prediction market platforms Kalshi and Polymarke
- Sports
- Economic forecasting
- Crypto markets
- IPO speculation
- Real-world event trading.
At the center of the legal fight is a fundamental question. Are prediction markets financial derivatives—or gambling?
Nevada and Washington Are Challenging Sports Event Contracts
According to court filings, regulators in both Nevada and Washington argue that certain contracts offered by Kalshi and Polymarket closely resemble sports betting rather than legitimate financial products. Nevada regulators specifically targeted sports-related event contracts tied to:
- Game outcomes
- Tournament results
- Sports performance markets.
Washington state officials similarly argued that some prediction contracts violate local gambling laws despite the platforms operating under broader federal commodity frameworks. Both companies attempted to halt the state-level actions while broader legal questions are resolved, but courts denied those requests, allowing enforcement proceedings to continue.
Kalshi Argues Prediction Markets Fall Under Federal Law
Kalshi has consistently argued that its markets are federally regulated derivatives overseen by the Commodity Futures Trading Commission (CFTC) rather than state gambling regulators. The company became the first federally regulated prediction market exchange approved by the CFTC in 2021. The platform maintains that event contracts tied to real-world outcomes function similarly to other commodity derivatives markets that help participants hedge risk and forecast future events.
Supporters of prediction markets argue these systems:
- Improve information discovery
- Aggregate market sentiment
- Provide economic forecasting tools
- Create alternative forms of financial analysis.
However, critics say many sports and entertainment contracts operate almost identically to traditional sportsbooks.
Polymarket Continues Facing U.S. Regulatory Pressure
Polymarket has faced increasing regulatory scrutiny in the United States for several years. In 2022, the platform reached a settlement with the CFTC over allegations it operated unregistered event-based binary options markets for U.S. users.
Despite geo-blocking U.S. users afterward, regulators and state authorities continue monitoring whether Americans are still accessing the platform through VPNs and alternative methods. The legal pressure has intensified as prediction markets increasingly expand into:
- Sports
- Elections
- Corporate forecasting
- Private company valuations
- Geopolitical events.
Recent launches tied to OpenAI, SpaceX, and sports contracts have only increased attention from regulators.
Sports Leagues and Regulators Are Now Involved
The lawsuits also arrive during a broader push by regulators and sports organizations to establish oversight around prediction markets. Just this week, the CFTC announced a formal integrity agreement with the NHL designed to monitor suspicious activity tied to sports prediction markets. Similar agreements have already emerged with Major League Baseball.
That signals prediction markets are increasingly being treated like mainstream financial infrastructure requiring:
- Surveillance systems
- Anti-manipulation protections
- Insider trading monitoring
- Institutional oversight.
At the same time, state regulators continue arguing many of these products fall under local gambling laws regardless of federal commodity regulation.
The Legal Fight Could Shape the Entire Industry
The outcome of these cases could have massive implications for the future of prediction markets in the United States. If courts ultimately side with state regulators, platforms like Kalshi and Polymarket could face:
- Geographic restrictions
- Product limitations
- State-by-state licensing requirements
- Expanded gambling oversight.
If prediction markets prevail, however, it could strengthen the argument that event contracts belong under federal financial regulation rather than traditional gambling frameworks. That distinction could determine whether prediction markets evolve into:
- A niche betting product
- Or a major new category of financial infrastructure.
The Bigger Picture
The legal battles involving Kalshi and Polymarket highlight how rapidly prediction markets are colliding with traditional regulatory systems. What started as niche crypto-based event trading platforms are now evolving into large-scale markets tied to:
- Sports
- Politics
- Economics
- Corporate valuations
- Global events.
As the industry grows, regulators are increasingly struggling to define where financial forecasting ends and gambling begins.
