Is Polymarket Legal in the US? — Complete 2025 Guide

Polymarket is the world's largest prediction market — but if you're in the United States, you've probably hit a geo-block or heard warnings about its legal status. So what's the actual story? Is Polymarket legal for Americans, and what are your options?

The short answer: Polymarket is not legally available to US residents. After a $1.4 million CFTC settlement in 2022, Polymarket blocked US users and remains off-limits to Americans. But the prediction market space is evolving fast — and there are legitimate, regulated alternatives you can use right now.

The CFTC Settlement: What Happened

In January 2022, the U.S. Commodity Futures Trading Commission (CFTC) filed and simultaneously settled charges against Polymarket's parent company, Lognition Inc. The core allegation: Polymarket offered binary options contracts to US persons without registering with the CFTC as a designated contract market or swap execution facility.

Polymarket agreed to pay a $1.4 million civil monetary penalty without admitting or denying the charges. It also agreed to stop offering markets to US persons and to implement geo-blocking measures to enforce this restriction.

Since that settlement, Polymarket has grown dramatically — it processed over $8 billion in trading volume during the 2024 US election alone — but all of that volume came from non-US users.

Current Legal Status in 2025

As of 2025, the legal picture is unchanged:

• US IP addresses are geo-blocked — Polymarket detects and blocks connections from US-based internet addresses.
• Terms of Service prohibit US persons — Even if you technically access the site, the ToS explicitly exclude US residents from trading.
• No CFTC registration — Polymarket has not applied to become a CFTC-regulated exchange, which would be required to legally serve US users.
• Crypto wallet KYC — Polymarket requires identity verification that can detect US persons even without geo-blocking.

Bottom line: attempting to use Polymarket as a US person — even via VPN — violates both the platform's Terms of Service and potentially US financial law. We do not recommend it, and this guide is not legal advice.

Legal Prediction Market Alternatives for US Users

The good news: if you're in the US, you have real options. The prediction market space is expanding, and regulated platforms are growing fast.

1. Kalshi — CFTC-Regulated, Best Option

Kalshi is a CFTC-regulated exchange offering prediction markets on economics, weather, finance, and politics. After a landmark 2024 court victory, Kalshi can now offer political event contracts including elections and Congressional outcomes.

• ✓ Fully legal for US residents
• ✓ FDIC-insured USD deposits
• ✓ Growing market catalog (500+ markets)
• ✗ Lower liquidity than Polymarket
• ✗ Fewer international/niche markets

2. PredictIt — Limited but Available

PredictIt operates under a CFTC no-action letter, allowing political and policy markets for US users. However, it has strict position limits ($850 per market contract) and announced potential closure in 2022 before winning a legal reprieve.

• ✓ Legal for US residents
• ✓ Focused on US politics
• ✗ $850 position limit per contract
• ✗ Small market selection
• ✗ Regulatory uncertainty persists

3. Sports Prediction Markets (State-by-State)

If you're interested in sports outcomes, regulated sports betting is available in 30+ US states. Platforms like DraftKings, FanDuel, and BetMGM offer prediction-style markets on sports outcomes with proper state licensing. These are not general prediction markets, but they scratch a similar itch for sports events.

For non-US users, Polymarket has more liquidity and a broader market catalog. Read our full Polymarket vs. Kalshi comparison for a deep dive.

Will Prediction Markets Become Legal in the US?

The regulatory tide is shifting — slowly but meaningfully. Several developments suggest a more permissive future for US prediction markets:

• Kalshi's 2024 court win — A federal appeals court ruled that Kalshi can offer political event markets, over CFTC objections. This established important legal precedent.
• Congressional interest — Multiple lawmakers have introduced bills to create clearer regulatory frameworks for prediction markets.
• CFTC rulemaking — The CFTC has indicated it may develop formal rules for event-based contracts, which could open the door for more platforms.
• Polymarket's growth — With $8B+ in 2024 volume, Polymarket has demonstrated massive demand. If regulations evolve, it could seek US registration.

Our take: within the next 3-5 years, it's plausible that a version of Polymarket — or a fully regulated US equivalent — becomes available to American traders. For now, Kalshi is the best legal option.
