US: Underdog Sues Missouri Over Prediction Market Restrictions
United States – 10 November 2026 – www.zonadeazar.com US-based platform Underdog has filed a lawsuit against Missouri authorities seeking to prevent the enforcement of state gambling legislation against its event contracts, marking another development in the ongoing regulatory dispute surrounding prediction markets.
The lawsuit was filed on 8 November 2026, making Missouri the eighth state in which the company has initiated legal proceedings concerning the regulation of these products.
Underdog Seeks to Block State Restrictions
The lawsuit names Missouri Attorney General Catherine Hanaway and officials from the Missouri Gaming Commission.
Underdog is asking a federal court to prevent state authorities from applying gambling legislation to event contracts traded through federally regulated derivatives platforms.
The company argues that these instruments should be classified as financial products governed by federal commodities legislation rather than conventional sports betting.
Under this interpretation, federal law would take precedence over Missouri’s gambling restrictions.
Sports-Related Contracts Under Scrutiny
The legal filing identifies several categories of event contracts currently available within the market.
These include products linked to:
- Potential NBA expansion.
- Developments during the MLB season.
- Sports collective bargaining negotiations.
- The possible sale of an NFL franchise.
Underdog maintains that these contracts allow participants to trade positions on future events and should therefore be treated as regulated financial derivatives.
However, state authorities have challenged the classification of such products when they are linked to sporting outcomes.
Missouri Strengthens Enforcement Against Operators
The dispute dates back to September 2026, when Missouri issued cease-and-desist orders to Underdog and five other operators.
The Missouri Gaming Commission determined that certain activities conducted by these platforms could constitute illegal gambling under state legislation.
The enforcement measures prompted a series of legal responses from affected companies.
Kalshi filed a lawsuit against Missouri in late October, while Crypto.com and Novig also initiated legal proceedings.
Underdog Challenges Regulators Across Eight States
Missouri joins an expanding list of jurisdictions where Underdog has taken legal action against regulatory restrictions.
The company had previously challenged enforcement measures in:
- Connecticut.
- Massachusetts.
- New Mexico.
- Ohio.
- Tennessee.
- Washington.
- Wisconsin.
With Missouri added to the list, Underdog has now initiated related legal proceedings across eight states.
The litigation strategy reflects the company’s efforts to establish a regulatory interpretation favourable to prediction-market operations across different US jurisdictions.
Debate Over Federal Regulatory Authority
Underdog’s central legal argument concerns the interpretation of federal commodities legislation and the jurisdiction of the Commodity Futures Trading Commission (CFTC).
The company maintains that event contracts traded through federally supervised platforms should not be subject to state regulations designed for traditional sports betting.
Missouri authorities, meanwhile, defend their ability to prevent activities they consider illegal gambling within the state.
The disagreement forms part of a broader legal controversy surrounding the classification of sports-related prediction markets.
Growing Litigation Across the Industry
The dispute between Underdog and Missouri coincides with an increasing number of lawsuits brought by prediction-market operators against state regulators.
Kalshi, Crypto.com and other companies are also seeking judicial clarification regarding the limits of state regulatory powers.
Operators argue that inconsistent regulatory approaches create legal uncertainty and complicate the nationwide expansion of their services.
State authorities maintain that they must retain the ability to protect consumers and regulate gambling activities within their jurisdictions.
Next Steps and Market Impact
The federal court will consider Underdog’s arguments and determine whether Missouri’s enforcement measures should be temporarily restricted while the case proceeds.
A ruling in the company’s favour could strengthen the position of other operators seeking to offer sports prediction markets under federal supervision.
Conversely, a decision supporting Missouri could reinforce state regulators’ authority to intervene against these platforms.
The case represents another significant development in the legal dispute that could shape the future of prediction markets across the United States.
