How do Polymarket and Kalshi differ in regulation and legal structure?

Detailed Explanation

The primary distinction between Polymarket and Kalshi lies in how each platform is structured to comply—or not comply—with U.S. financial regulation. Kalshi is registered as a Designated Contract Market (DCM) with the CFTC, meaning it must adhere to strict rules around market design, participant eligibility, contract approval, reporting, and dispute resolution. This regulatory status provides legal clarity and enforceability but also limits the types of markets Kalshi can list and who can participate.

Polymarket, by contrast, operates using blockchain infrastructure and smart contracts, typically settling trades in stablecoins. This design allows Polymarket to list a broader range of markets more quickly and attract global participation, but it also places the platform outside traditional U.S. regulatory frameworks. As a result, access for U.S.-based users is restricted, and legal protections differ materially from regulated exchanges. From a market-intelligence perspective, these regulatory differences directly shape liquidity, participation, and the types of signals each platform produces.

Common Scenarios

• Evaluating compliance risk when using prediction market data
• Comparing U.S.-regulated vs global prediction markets
• Assessing institutional suitability of market signals
• Understanding why certain markets exist on one platform only

Exceptions & Edge Cases

• If regulatory policy changes, then platform access and market availability may shift quickly.
• If a market exists on both platforms, then legal structure may still affect pricing behavior.
• If users access markets indirectly, then legal exposure varies by jurisdiction.

Practical Examples

• A U.S. macroeconomic indicator is listed on Kalshi with CFTC approval.
• The same or similar event may appear on Polymarket without regulatory review, allowing faster listing but different risk considerations.

Actionable Takeaways

• ✅ Understand regulatory context before interpreting prices
• ✅ Treat regulated and unregulated markets as structurally different signals
• ✅ Consider legal structure when using data for enterprise decisions
• ✅ Monitor regulatory developments that may affect access or liquidity
