Missouri's regulatory landscape for betting shifted significantly with the passage of Amendment 2 in November 2024, which authorized licensed sports betting. This has created questions about the status of other novel markets, specifically event contracts and prediction markets. This guide provides a detailed analysis of Missouri's legal framework as it applies to these instruments, distinguishing between the new state-level sports betting regime and the existing federal oversight for event contracts. We examine the relevant statutes, regulatory bodies, and platform-specific access for Missouri residents.
Missouri is classified as an Open state for prediction markets. The federal framework, overseen by the Commodity Futures Trading Commission (CFTC), applies to federally registered Designated Contract Markets (DCMs). While Missouri voters approved Amendment 2 to legalize sports betting under the Missouri Gaming Commission's authority, the state has no specific laws or public regulatory opinions against CFTC-regulated event contracts. Access varies by platform: Kalshi's availability depends on its policies, Polymarket excludes all US users, and AGON's permissionless model operates within federal and state guidelines.
The primary legal framework governing event contracts in the United States is federal, not state-based. The Commodity Exchange Act grants the Commodity Futures Trading Commission (CFTC) exclusive jurisdiction over futures, options, and certain event contracts. Platforms that wish to offer these products legally to US persons must register with the CFTC as a or a Swap Execution Facility (SEF). This federal registration generally preempts state-level attempts to regulate the same instruments as gambling, provided the platform adheres to its federal charter.
In Missouri, the state-level regulatory body is the Missouri Gaming Commission (MGC). Historically focused on riverboat casinos, its mandate expanded significantly after Amendment 2 passed in November 2024 to include the licensing and oversight of sports betting operators. The MGC is currently developing the rules and procedures to implement this new sports betting framework. It's crucial to understand that the MGC's authority under Amendment 2 applies to licensed sportsbooks, not to federally regulated event contract platforms. For a comprehensive overview of the national landscape, read the full 50-state guide.
While the federal framework is dominant, state law remains relevant for defining what constitutes illegal gambling and for activities that fall outside the CFTC's jurisdiction.
Missouri's core gambling statute is found in the Missouri Revised Statutes §572.010. This section defines "gambling" as "staking or risking something of value upon the outcome of a contest of chance or a future contingent event not under his control or influence, upon an agreement or understanding that he will receive something of value in the event of a certain outcome." The statute establishes the criminal framework for unauthorized gambling.
Historically, Missouri's Constitution (Article III, §§39 and 39(e)) placed strict limits on lotteries and gambling. The passage of Amendment 2 in November 2024 carved out a significant exception, constitutionally authorizing the legislature to permit sports betting. This amendment directs the MGC to regulate the activity, issue licenses to qualified operators, and collect taxes on revenue. The implementation process is ongoing, with the MGC focused on establishing the new licensed market.
The two primary regulatory bodies are the Missouri Gaming Commission and the Missouri Attorney General office. The MGC oversees all licensed gaming, now including sports betting. The Attorney General has broader authority to enforce consumer protection laws and prosecute illegal gambling operations.
As of this publication, neither the MGC nor the Attorney General has issued a public statement, advisory opinion, or enforcement action specifically classifying CFTC-registered event contracts as illegal gambling under §572.010. [INFERENCE] This lack of adverse action contributes to Missouri's classification as an Open state. The prevailing assumption is that regulatory attention and resources are currently dedicated to the complex rollout of the licensed sports betting market authorized by Amendment 2.
The most significant recent activity was the passage of Amendment 2. The Missouri Senate and Missouri House are now engaged in the legislative and budgetary processes to support the MGC's implementation. This includes defining licensing criteria, tax rates, and consumer protection rules for sports betting.
There has been no specific legislation introduced or enacted in Missouri to either explicitly authorize or prohibit prediction markets or event contracts that fall under the CFTC's jurisdiction. Consequently, the state's Open status is a reflection of the current reality: federal preemption for CFTC-regulated platforms remains unchallenged, and the state's regulatory focus is fixed on launching its new sports betting industry.
Access to prediction markets for Missouri residents depends entirely on the specific platform's regulatory status and internal policies.
Kalshi is a CFTC-registered Designated Contract Market. As such, it operates under the federal preemption framework. For states classified as Open like Missouri, access is typically permitted, subject to Kalshi's own terms of service and standard user verification processes. Missouri residents should always verify their eligibility directly on Kalshi's website, as availability can change. For more context, see our in-depth Kalshi review.
Polymarket does not permit access for any users in the United States. This is a global policy resulting from a 2022 settlement with the CFTC, which required the platform to cease offering markets to US persons and pay a civil penalty. This restriction applies to all states, including Missouri, irrespective of local laws.
AGON is a sport betting crypto platform built on the Base blockchain, featuring an open AI Agent Arena and a full gamification stack. The platform's availability is determined by a user's jurisdiction, with geoblocking technology used to comply with the CFTC framework and state-specific gambling laws. For Missouri's Open status, access generally aligns with the federal framework for event contracts. Users should consult the platform's terms of service and review the AGON compliance and security posture to confirm current availability and registration status before trading in the AGON sport markets catalog.
For Missouri residents considering trading on event contract platforms, a few points of verification are critical.
This article is not legal advice. Missouri Revised Statutes §572.010, the Missouri Gaming Commission framework, and Amendment 2 (2024) govern gambling and sports betting in Missouri. Consult the Missouri Gaming Commission, the Missouri Attorney General office, and a Missouri-licensed attorney before relying on any classification. AGON does not provide legal advice.
Prediction markets involve risk. Past performance does not predict future results. Capital is at risk. This article is not financial advice. Bet responsibly.

Kalshi is registered with the federal Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM). Because Missouri is classified as an Open state with no specific laws or regulations prohibiting CFTC-regulated event contracts, Missouri residents can typically access Kalshi. This is subject to Kalshi's own terms of service and onboarding procedures. Users should always verify their eligibility directly on kalshi.com, as platform policies can change.
No. Polymarket is not accessible to any users within the United States, including Missouri. This restriction is a result of a 2022 settlement agreement with the CFTC. The platform's terms of service explicitly prohibit US persons from using its services, a policy that overrides any individual state's laws regarding prediction markets or sports betting.
Missouri's stance is considered Open. The state has not passed any laws specifically addressing event contracts, nor have the Missouri Gaming Commission or the Attorney General issued any public opinions classifying them as illegal gambling. With the passage of Amendment 2, regulatory focus is on implementing a licensed sports betting framework. In the absence of state-level prohibition, the federal framework governed by the CFTC and the Commodity Exchange Act remains the prevailing authority for registered platforms.
AGON employs geoblocking technology to ensure compliance with federal and state-specific regulations. As Missouri is an Open state, access for its residents generally follows the federal framework governing event contracts. However, users must verify the platform's current federal registration status and confirm Missouri is not on any restricted list in the terms of service before attempting to trade. User responsibility and verification are key components of the AGON compliance and security posture.
Yes. Missouri voters passed Amendment 2 in November 2024, which amended the state constitution to authorize and regulate sports betting. The Missouri Gaming Commission is tasked with creating the rules, issuing licenses to operators, and overseeing the new industry. It is important to note that Amendment 2's scope is limited to licensed sports betting operators and does not apply to or authorize CFTC-regulated event contracts, which operate under a separate federal legal framework.
