Verdict
Casinos.com Expert Review
Polymarket is the world's largest prediction market by volume. For US users, access is via a dedicated CFTC-regulated app, though it's still invite-only and mobile-only. We can offer you an invite code – CASINOS - so you can jump right on.
I don't like the early teething problems with the software. I do like the great deposit options and wide range of markets. I give Polymarket my strong recommendation.
What Is Polymarket?
Polymarket is a peer-to-peer prediction market where users trade outcome shares - not a casino, and not a sportsbook. There's no house. You trade against other users, and the market price at any moment reflects what all those users collectively believe is likely to happen.
Here's the core mechanic:
Every market is a YES/NO question: "Will X happen by date Y?"
You buy shares in YES or NO.
Shares are priced between $0.01 and $1.00
If you're right, each share pays exactly $1.00. If you're wrong, your shares pay $0.00
You can sell your shares at any time to another buyer at the market price
A share trading at $0.65 means the market currently gives that outcome a 65% chance of happening. As news breaks and circumstances change, prices move in real time.
This is fundamentally different from sports betting. At a sportsbook, you’re wagering against the house, which builds a margin into every line. On Polymarket, the house doesn’t exist. Prices reflect genuine supply and demand between real traders, which is why Polymarket’s markets have attracted serious attention from forecasters, researchers, and institutional investors — not just people looking for a flutter.

Polymarket Invite Code
This is what I got when I tried to sign up for Polymarket! 1.3 million on the waitlist. We are lucky to have been offered the chance to invite our readers to the new US Polymarket App. Use our Polymarket Invite Code CASINOS and you go to the head of the line. Claim a $20 bonus when you make your first deposit – just to get you started.
Polymarket Deposit Options
You can use GooglePay, Appe Pay, credit and debit cards, bank wire transfers and crypto fund your Polymarket trades. We recommend GPay or ApplePay as some banks aren't yet up to speed with retail market trading on Prediction markets and we have reports of many transactions being declined.
The Polymarket Cashier is simple to the point of elegance. Your balance is always visible as is the value of your Portfolio. You can see all recent deposits and withdrawals on the relevant tabs. You can see the positions you hold and your history so you can track exactly how you are doing.
Polymarket Uses USDC for Trades
Polymarket uses the USDC stablecoin for all of its trades. You have to convert your dollar account balance to USDC at the rate of $1 to USDC 1 to place trades. Polymarket integrates the MoonPay app so you can do this quickly. There is a $20 minimum deposit and you have to be 18 before you can trade.
It works, but it’s an extra step that I felt added unnecessary complication. Theoretically the rate of exchange should never change, that’s why it’s called a stablecoin.
What Markets Does Polymarket Offer?
Polymarket runs over 1,000 active markets at any given time across six main categories. Politics and elections consistently generate the highest volume — the 2024 US presidential election alone saw over $3.3 billion wagered, making it the most traded event in the platform’s history.

How Markets Work
Anyone can propose a new market, subject to Polymarket’s approval. Once live, markets can run from a few hours (breaking news) to several years (long-term political outcomes). Most are binary YES/NO, though some offer multiple outcome options — for example, “Which party wins the Senate majority?”
Live Markets
One market type unique to Polymarket: live markets that update in real time during events. Crypto price markets run continuously and resolve at defined daily or weekly windows based on real exchange data.
Advantages
No house edge - you trade against other people
Massive liquidity on politics and crypto markets
Near-zero fees
Excellent deposit options
Federally regulated by the CFTC
Disadvantages
1 million+ waitlist unless you have a Polymarket invite code
US access is mobile-only for now
I’d prefer USD to USDC crypto trading but MoonPay makes it easy
Weak responsible trading tools – we want more for retail customers
Polymarket software is barely coping with high user volumes
How is Polymarket Available in the US?
It is available but its regulation has recently changed. Federally legal as of late 2025 — but invite-only, mobile-only, and facing state-level pushback.
Last Verified: May 2026, 2026
US state access status is subject to change. This section is reviewed monthly. If you believe any information is outdated, contact our editorial team.
The Full Picture
January 2022
The CFTC fined Polymarket $1.4 million and issued a cease and desist for operating an unregistered binary event contracts facility. Polymarket agreed to block US users as part of that settlement.
July 2025
The DOJ closed a separate investigation into Polymarket. In the same period, Polymarket acquired QCEX, a CFTC-licensed futures exchange, providing the legal path back to US operations.
Late 2025
The CFTC issued a no-action letter permitting Polymarket to operate regulated event contracts in the US under its QCEX license.
December 3, 2025
US app launched — invite-only, mobile-only, with a waitlist reportedly over one million users. The international platform at polymarket.com still geo-blocks US IP addresses.
What This Means Practically
US users must use the separate regulated US portal — not polymarket.com
Full KYC required: government ID, Social Security number, selfie
Mobile app only — desktop trading not yet available for US users
State-Level Restrictions
Despite federal CFTC approval, Nevada, Tennessee, Massachusetts, and Connecticut have taken legal action against prediction market platforms. At least 11 states had issued cease-and-desist orders as of March 2026. Courts have not yet reached a consensus on whether federal CFTC approval preempts state gambling laws.

Polymarket is the world's largest prediction market platform, founded in 2020, where users trade YES/NO shares on the outcomes of real-world events. Shares are priced from $0.01 to $1.00, with the price reflecting the market's implied probability that the event occurs. Winning shares pay out exactly $1.00 each at resolution.
Is Polymarket available in the United States?
Yes, but with significant restrictions. A CFTC-regulated US app launched in December 2025 and is currently invite-only, mobile-only, and unavailable in nine states including Nevada, Massachusetts, and New Jersey. The main international platform (polymarket.com) still geo-blocks US IP addresses. Federal approval exists, but state-level legal challenges are ongoing.
Does Polymarket have an invite code?
US beta users can skip the waitlist using our Polymarket invite code CASINOS. Just enter it when you sign up for your account.
How does Polymarket work?
You sign up, deposit USDC (a stablecoin worth exactly $1), find a market, and buy YES or NO shares. Share prices reflect the crowd's probability estimate for an outcome. If you're right when the market resolves, each share pays $1.00. You can also sell before resolution if prices move in your favor.
Is Polymarket gambling?
Not in the traditional sense. Polymarket is a prediction market — users trade shares against each other, not against a house. There's no bookmaker setting lines or building in a margin. It's regulated in the US as event-contract trading under the CFTC, not as gambling. That said, real money is at risk, outcomes are uncertain, and you can lose your entire stake.
What currency does Polymarket use?
Polymarket uses USDC (USD Coin), a stablecoin pegged 1:1 to the US dollar, running on the Polygon blockchain. One USDC always equals one dollar — there's no crypto price volatility affecting your balance. All deposits, trades, and payouts happen in USDC.
Is Polymarket legit and safe?
Yes. Not only regulsated by the federal government but Polymarket has paid out correctly on tens of thousands of markets since 2020. Smart contracts have been audited by OpenZeppelin, Cantina, and Quantstamp. Funds held in self-custody wallets are yours regardless of what happens to the platform. The main risks are smart contract exploits, oracle disputes, and regulatory changes.
