Polymarket US Review

Polymarket is one of the biggest players in the booming prediction market industry in the US. It allows you to make easy yes/no predictions on a huge range of topics, from sports and politics to climate and crypto. Our Polymarket US review is breaking down how it all works, so you can start making trades on the Polymarket US app now. 

What Is Polymarket US?

Polymarket is a real-money prediction market app that launched in 2020. It has been federally regulated and legal in the US since 2025. 

Polymarket is a peer-to-peer platform, which means the predictions you make are against other users of the exchange. In the US, the Polymarket app was initially limited to sports markets, but it has since added politics, climate, and cryptocurrency markets

Trading on Polymarket US is as simple as answering “yes” or “no” questions, like “Will the temperature reach 80 degrees in New York tomorrow?” Trades are built around contracts, which are priced between $0.01 and $1.00. You can buy as many or as few as you like. 

Once they are settled, correct predictions are paid out at $1 per contract. Incorrect predictions are worth nothing. 

Is Polymarket US Legit and Secure?

Yes, Polymarket is a legitimate prediction market. Despite some bumps in the road, it has several security measures in place to protect US players. 

Significantly, Polymarket US prediction market is federally regulated, thanks to its 2025 acquisition of QCX, LLC. The CFTC approved QCX to operate as a Designated Contract Market (DCM) in July 2025. This cleared the way for Polymarket to re-enter the US several years after being banned by the CFTC.

All Polymarket trading is recorded on the Polygon blockchain for transparency. It aims to deter insider trading by performing market surveillance through Palantir, TWG AI, and other third-party firms.

Despite its legal status, Polymarket is proceeding carefully in the US. It currently accepts users from 41 US states and Washington, DC. It’s not available in Arizona, Illinois, Massachusetts, Maryland, Michigan, Minnesota, Montana, Nevada, and Ohio.

How to Sign Up and Get Started

Polymarket US launched iOS and Android apps in December 2025, but initially required users to sign up for a waitlist. It has since eliminated the iOS waitlist, but an Android waitlist still exists.

Here’s how you can start trading now:

1. Download the iOS and Android app: Visit the App Store or Google Play Store.
2. Set up an account: Use your Google account, email address, or Web3 wallet.
3. Go through the ID verification process: You’ll need to provide personal information, including your name, location, DOB, and Social Security number.
4. Fund your new account: Add funds using USDC crypto via the Polygon market, or make a deposit with a debit/credit card or bank transfer. Enter a Polymarket promo code if you have one.
5. Check out markets and complete your first trade: Right now, you can make simple “yes” or “no” predictions on a range of topics, including sports, politics, weather, and more. 

A Polymarket NBA contact looks like this:

San Antonio Spurs vs. Oklahoma City Thunder - “Victor Wembanyama: 20+ Points?”

• Yes ($0.81)
• No ($0.20)

In this case, investing $100 in “yes” yields a $122 payout if Wembanyama scores 20+ points against OKC. Investing $100 in “no” results in a payout of $479 if Wembanyama scores under 20 points.

Furthermore, the prices of contracts are a direct reflection of the probability of each event, according to Polymarket US users. In this case, the public believes there is an 81% chance of Wemby shooting 20+ points. 

Available Markets and Event Types

Polymarket US offers a decent variety of markets and event types. Sports markets are especially popular in states like California, Texas, and Georgia, where regular sports betting hasn’t been legalised.

Here is an overview:

• Sports: NFL, NBA, MLB, NHL, etc.
• Politics: Election winners, policy outcomes, etc.
• Weather: High temperatures in major cities, precipitation totals, etcPolymarket US also mentions that “more markets are coming soon.” This makes sense when you compare the US app with Polymarket’s internationally facing site, where you can find far more topics, including pop culture, tech, economic indicators and many more.

The prices of contracts (between $0.01 and $1.00) change all the time according to how users are trading. That said, Polymarket generally has fairly stable pricing, thanks to its large user base. This helps avoid wild swings and makes it easier to buy and sell at predictable prices. 

Polymarket US doesn’t presently enforce maximum trading limits. It has Market Integrity Rules designed to thwart fraud, insider trading, and market manipulation.

Fees and Payouts: What Does It Cost?

Fees are a little complicated at Polymarket US. Instead of a fixed rate, the platform utilises a dynamic taker fee structure. 

This means that fees change based on factors ranging from market category to contract prices. Some markets, such as geopolitical and world events, have no fees, while others, like sports, have at least small fees.

Polymarket US fees are lowest for those who trade contracts closest to $0.01 and $1.00 and highest for those who trade contracts closer to $0.50. All that said, the highest fees are around 0.75% for sports contracts, 1% for politics contracts, and 1.25% for climate contracts.

If you create contracts, you can sidestep fees completely. In some instances, makers are even rewarded with 0.20% rebates for contributing to Polymarket’s high liquidity.

Once events end, contracts are typically settled within a few hours. They’re automated via blockchain smart contracts, with applicable fees removed. Profits are credited to Polymarket portfolio balances.

User Experience: Platform, App, and Interface

We found the Polymarket US mobile app clean and intuitive to use. Compared with Polymarket’s international website - which crams a lot of information and markets on-screen - it’s clear that the US platform has been tweaked to make it as easy as possible for beginners. 

Making a trade is as simple as tapping on a contract, typing in how much you want to invest, and confirming the purchase. It feels relatively similar to using a sports betting app, in that respect. 

We were also impressed with how efficient the app is when changing contract prices. We reviewed it during the Indianapolis 500, and it was quick to update contract prices in real time.

Customer Support

Polymarket provides several reliable customer support options, including a live chat, an email, and even a Discord channel. It also has a useful FAQ/Help section.

We suggest sticking with the live chat when you need support. We tested it several times and received near-instant responses every time. The Discord channel is also great for getting tips from other traders.

Deposits, Withdrawals, and Payment Methods

Polymarket US lets you use Apple Pay, a debit card, or crypto to fund your account. You must deposit at least $20 for fiat deposits and at least $2 for crypto deposits, though crypto minimum deposits can change based on which type of crypto you use

The Polymarket US app also supports fast withdrawals via debit card, bank transfer, or crypto. In our experience, fiat withdrawals take a couple of days to process, but crypto comes through in minutes. 

There are no deposit or withdrawal limits mentioned. Overall, we found the process very simple, on par with what we’ve experienced at other top prediction markets like Kalshi. 

Final Thoughts: Who Should Use Polymarket US?

Polymarket brands itself as “the world’s largest prediction market”, and it feels like this is just the start in the US. 

Placing trades on the Polymarket US app is nice and simple, and the large user base guards against unpredictable pricing. The platform is fully legal and regulated, and we liked the flexibility of using either fiat or crypto. 

With more markets and topics coming soon, and the removal of the iOS waitlist, now is a great time to get in on the ground floor at Polymarket US.
