How Are Kalshi and Polymarket Worth Billions Without a Gambling License? | WSJ The Economics Of

Key Concepts

• Prediction Markets: Platforms where users trade contracts based on the outcome of future events.
• Event Contracts: Financial instruments structured as "Yes/No" propositions; a correct prediction pays $1, while an incorrect one pays $0.
• CFTC (Commodity Futures Trading Commission): The U.S. federal agency that regulates derivatives and event contracts, classifying them as "swaps."
• Market Makers: Entities (like Kalshi Trading LLC) that provide liquidity to an exchange by posting buy and sell orders, helping to set contract prices.
• Liquidity: The ease with which assets can be traded without significantly affecting their price.
• Derivatives: Financial contracts whose value is derived from an underlying asset or event.

1. Mechanics of Prediction Markets

Prediction markets operate on the principle that the price of an event contract (ranging from $0 to $1) represents the market-implied probability of that event occurring.

• Pricing: If the market sentiment shifts toward an event happening, the price rises toward $1; if sentiment shifts against it, the price drops toward $0.
• Business Model: Unlike traditional sportsbooks that act as "the house" and often limit successful bettors, prediction markets function as exchanges. They generate revenue by collecting transaction fees on the volume of trades, incentivizing them to encourage high user activity rather than banning successful professionals.

2. Regulatory Landscape and Legal Battles

The industry is currently divided between regulated entities and offshore platforms:

• Kalshi: Fully regulated in the U.S. by the CFTC. It obtained its license in 2020, allowing it to operate as a "designated contract market."
• Polymarket: Operates primarily offshore to offer a wider array of contracts, though it has recently introduced a CFTC-compliant platform for U.S. users.
• The Sports Betting Conflict: A major legal battle is brewing regarding whether these platforms should be subject to state-level gambling licenses. While 39 states have legalized sports betting, many states (such as California and Utah) have not. Critics argue that if these platforms function like gambling, they should be regulated by states, not just federal commodity regulators.
• Congressional Scrutiny: Bipartisan efforts are underway in Congress to ban sports betting on prediction markets, with lawmakers arguing that states should retain the right to decide on gambling legality within their borders.

3. Market Participants and Risks

• Professional Bettors: Individuals like Frank Satlo utilize these platforms because they lack the restrictive betting limits imposed by traditional sportsbooks.
• Market Makers: Kalshi utilizes an internal arm, Kalshi Trading LLC, to provide liquidity. While controversial, the platform maintains that institutional market makers are industry standard and account for a small percentage of total volume.
• Profitability Data: Analysis suggests that the vast majority of users are unprofitable. A Wall Street Journal report on Polymarket indicated that roughly 0.1% of accounts capture the majority of winnings, while the median loss for casual users is under $10.

4. Insider Trading and Market Integrity

The CFTC has asserted its exclusive authority to police fraud and manipulation in these markets.

• Enforcement: Polymarket has faced scrutiny for insider trading, including a notable case involving a soldier who allegedly profited $400,000 by betting on the political outcome in Venezuela.
• Compliance: Both platforms have implemented rules against trading on stolen confidential information or illegal tips. Kalshi claims to actively monitor for information leaks to prevent unfair advantages.

5. Notable Perspectives

• The CFTC Stance: The agency views itself as the primary regulator of event contracts and has signaled a willingness to defend its authority in court against state-level challenges.
• Industry Influence: The involvement of high-profile figures, such as Donald Trump Jr. as an advisor to both Kalshi and Polymarket, highlights the political intersection of these platforms.
• Expert Outlook: Analysts suggest the industry is moving past a "free-for-all" phase. The future likely holds increased regulatory oversight, more frequent prosecutions for insider trading, and clearer legal delineations regarding what constitutes a "predictable event" versus "illegal gambling."

Synthesis

Prediction markets represent a significant evolution in financial technology, shifting from niche hobbyist sites to multi-billion dollar entities. While they offer a unique mechanism for aggregating information and providing liquidity for professional bettors, they face an existential threat from state-level gambling regulators and federal lawmakers. The industry's survival depends on its ability to satisfy the CFTC’s regulatory requirements while navigating the complex, fragmented legal landscape of U.S. state gambling laws. The trend points toward a more restricted, highly monitored environment where market integrity and compliance will be the primary determinants of long-term viability.
