Is Polymarket Legal in the US?

Polymarket is not available to US residents under its current terms of service. The platform explicitly prohibits participation from the United States, citing US regulatory restrictions on prediction markets and event-based derivatives contracts.

Polymarket is not a CFTC-regulated exchange. It operates as a decentralised blockchain-based platform on the Polygon network. Without CFTC designation as a Designated Contract Market (DCM), it cannot legally offer its contracts to US persons under the Commodity Exchange Act.

The legal issue stems from how the CFTC classifies prediction market contracts. Under US law, contracts whose value depends on the outcome of a future event (elections, economic data, sports results) are considered "event contracts" under the Commodity Exchange Act.

Offering these contracts to US persons without a CFTC licence is illegal. Polymarket has not applied for — and does not currently hold — the required CFTC licence to operate in the US. Rather than navigate the regulatory process, Polymarket restricts US IP addresses and requires non-US attestation.

This is not a judgment about whether Polymarket is "safe" or "legitimate" — it is purely a regulatory jurisdictional issue.

Some US residents access Polymarket using VPNs or by falsely attesting to being outside the US. This carries several risks:

• Terms of service violation — your account can be banned and winnings potentially withheld
• Regulatory risk — while individual users have rarely faced enforcement, using a prohibited platform is not risk-free
• No legal recourse — if a dispute arises over a market resolution or withdrawal, you have no legal protection as a US person on an unregulated platform

We strongly recommend against this approach. There are now legitimate US alternatives.

Kalshi is the primary legal option for US residents. It is a CFTC-regulated Designated Contract Market, meaning it can legally offer event contracts to US persons. Kalshi lists markets on Fed rate decisions, elections, economic data releases, and other events similar to Polymarket.

PredictIt is another CFTC-regulated option, focused exclusively on political markets. It has a $850 per-market position cap and higher fees than Kalshi, but has operated legally in the US since 2014.

PaperPoly lets you trade live Polymarket odds with virtual money — completely legally, with no real money, no wallet required, and no geographic restrictions. It's the best way to practice Polymarket-style prediction trading before committing real capital to any platform.

Potentially yes. The regulatory environment for prediction markets in the US is evolving rapidly. The political climate following the 2024 election cycle — in which Polymarket's presidential markets outperformed traditional polling — has increased pressure on regulators to create a workable framework for prediction markets.

Kalshi's CFTC designation in 2023 demonstrated that the regulatory pathway exists. If Polymarket were to apply for and receive CFTC designation, or if Congress passes legislation creating a clearer framework for event contracts, US access could become legal.

For now, the legal answer remains: Polymarket is not available to US residents, and the safest approach is to use CFTC-regulated alternatives or practice with PaperPoly.
