Polymarket & Kalshi Legality in US: Federal Status and Access

Prediction market platforms are becoming increasingly popular as users look for alternatives to traditional sports betting, but their legal status in the US can vary depending on the regulatory framework and the state. 

If we are trying to give the short answer, then it’s yes. Both platforms operate legally in the United States with federal approval. Kalshi operates as a direct exchange under CFTC oversight. Polymarket, on the other hand, purchased its licensed status through a nearly $112 million acquisition. 

We’ll walk you through live active state lawsuits and outline the current deposit rules so you can feel secure trading.

Polymarket legally clears you to trade within specific regions of the U.S. Thanks to individual state laws and waitlist rollout, you get account access. Federal regulations have changed enforcement for this exchange through several large enforcement milestones and buyout deals.

Is Kalshi Legal in the US?

You have the right to trade on Kalshi within the U.S. thanks to Federal licenses. Unlike Polymarket, this exchange comes under direct CFTC control rather than local gambling boards. Thanks to several large enforcement milestones and buyout deals, retail traders now have a path through the federal courts.

Kalshi vs Polymarket Legal Status

The CFTC’s rules apply to both websites, but the real differences are how each was registered, how capital flows, and the types of legal challenges each faces. The table helps you better understand the two websites.

That funding-rail split matters at deposit time — ACH and wire transfers clear almost instantly on Kalshi, while Polymarket has an FCM in the US that adds a broker step which means your funds don’t really count until the trading balance has been funded.

CFTC Oversight of Event Contracts

Federally regulated prediction markets run under direct Commodity Futures Trading Commission oversight. The CFTC framework covers how event contracts are offered, how trading platforms are registered, and how customer funds move through regulated intermediaries. 

• CFTC has federal jurisdiction over event contracts instead of state gambling boards;
• Designated Contract Market gives eligible trading exchanges;
• Futures Commission Merchant is your cash brokerage account provider to move funds to trading accounts;
• Exclusive Jurisdiction gives national commodity regulators the right to exercise a license over derivative markets;

• IRS Code 1256 Contract: enables traders to file taxes at the favorable 60/40 split using Form 6781.

State-Level Restrictions on Event Contracts

There are individual state regulators who have impeded federal oversight by closing retail trading access in their states. Prediction markets in these states are treated as sportsbooks rather than licensed commodity exchanges, and therefore predictive trading is restricted. Court orders intervene and dictate where trading is legal.

• Cease-and-desist letters tell exchanges to halt and refund local operations;
• Statutory penalties charge unlicensed venues $10,000 to $25,000 for each subsequent violation;

• In federal lawsuits, attorneys defend the seven state CFTC supremacy Federal lawsuits against the State bans;
• Prosecutor coalitions unite 38 state attorneys general backing regional authority over gambling;
• Ongoing court battles continue to shape where and how event contracts can be offered in the US.

Polymarket Account Access and Funding Rules
