Polymarket Review

Polymarket summary

Polymarket has been around since 2020, but it really became mainstream during the 2024 US presidential election. 

Its markets called several major outcomes before traditional polls did, and that put the platform on the map. By 2026, it had processed more than $27 billion in total trades.

The concept is simple. Users buy Yes or No shares priced between $0.01 and $0.99 on real-world events. Winning shares pay out $1 each. Markets span sports, politics, crypto, finance, culture, and more.

To get started on the platform, new users can input Polymarket promo code SBR to earn $20 in bonuses after depositing $20. This will also allow users to skip the US waitlist.

US access took a while to sort out. The CFTC hit Polymarket with a $1.4 million settlement in 2022, and the platform had to block American users for nearly three years. However, after acquiring a CFTC-licensed exchange and securing full regulatory approval, the platform became available to US citizens again in late 2025.

Globally, Polymarket offers the full range of categories with trades settled in USDC on the Polygon blockchain. Polymarket US is still in its early stages and currently covers sports only. All trades happen in US dollars, with deposits available through ACH, wire transfer, debit card, and Apple Pay. There is also a native app on both iOS and Android.

Polymarket vs. Polymarket US: Important access note

The international Polymarket platform and Polymarket US are separate legal entities with different regulatory statuses. The CFTC lists QCX LLC d/b/a Polymarket US as a designated contract market (DCM) and derivatives clearing organization (DCO).

In practice, Polymarket US operates like a traditional futures exchange. All trades settle in US dollars. Deposits go through ACH, wire transfer, debit card, or Apple Pay, and the platform currently covers only sports. 

The international version is crypto-based, runs on Polygon, settles in USDC, and offers the full range of market categories. 

The trading experience also differs in important ways. Polymarket US does not support limit or resting orders, which removes a key tool for price control. 

Fee models are different, too. Internationally, taker fees use a dynamic curve that varies by category, while Polymarket US charges a flat 0.30% taker fee with a 0.20% maker rebate. 

Throughout this Polymarket review US and the comparison to its international counterpart, I’ll make sure to specify which product each section refers to so that there is never any confusion.

What is Polymarket?

Every market on Polymarket is a Yes or No contract tied to a real-world event. Each share trades between $0.01 and $0.99, and the price reflects what the crowd thinks the probability of a specific outcome is. The closer a share is to $1.00, the more likely the market considers that outcome.

You can buy as many shares as you want at the listed price. Behind every purchase is a trader on the opposite side. If you pay $0.40 for Yes, someone else has paid $0.60 for No.

Prices are set through a central limit order book (CLOB), and the displayed price is typically the midpoint of the spread. 

That matching process is why liquidity matters. In active markets, orders fill fast and at fair prices. In quieter ones, you may have to settle for a worse price or wait longer for a match.

Say you buy 100 Yes shares at $0.40 on a “Will Team X win the title?” market. If Team X wins, each share pays $1.00, and you walk away with $60 in profit, minus the fees.

You don’t have to wait for the final result. You can sell all or part of your position whenever you want. If Yes moves to $0.70 after a hot streak, you can sell and lock in $0.30 per share. You can also add more shares if you think that the price is still favorable for the expected outcome.

Sportsbooks offer cash-out options, too, but you typically give up part of your potential payout to use them. Here, the price is set by the open market, so a well-timed exit can actually net you more than your original position would have paid at settlement. And you always have the option to sell, unlike at a sportsbook, where cash-out options are only available sometimes.

What also separates Polymarket from a sportsbook is the absence of a built-in vig. A typical book builds its margin into the odds, which is why you often see -110 on both sides of a spread. On Polymarket, prices come straight from the order book with no markup.

Polymarket offers one of the best prediction market promos: $20 in bonuses after depositing $20. Check out how it compares to other great offers in the industry, such as the ones available via the Kalshi promo code, OG.com promo code, Robinhood promo code, and FanDuel Predicts promo code.

How Polymarket works

Getting started at Polymarket US shouldn’t take more than five minutes, but the global version can be a bit more complex, especially if you are new to crypto wallets.

1. Create your account: If you are using the international version, sign up through Google, email, or a crypto wallet. For Polymarket US, join the waitlist with your phone number and download the app once you get access. You will also need to complete KYC verification.
2. Add funds: Globally, deposit USDC on Polygon from a crypto exchange or buy it directly through MoonPay’s card on-ramp system. Polymarket US keeps things simple. Deposit with a debit card or bank transfer, and you’re ready to go. 
3. Find a market: Browse the categories or search for a specific event. Every listing shows the current price, which tells you the crowd’s estimated probability.
4. Make your move: Buy Yes or No shares at the listed price, or set a limit order at a level you prefer and wait for a match. All versions support marketable and resting limit orders.
5. Collect or cash out: Winning shares pay $1 each once the event ends. If you want out early, sell your position on the open market at the current rate.

Polymarket review

I spent a good amount of time poking around both the desktop and mobile sites. Here's what stood out to me the most.

Website and Polymarket app experience

The international version offers a full desktop and mobile experience. I had no trouble with order book views, price charts, trade history, and market discovery. Everything loads fast and feels well-organized.

Polymarket US is app-only for now, with no desktop version. The interface is more stripped back. You get a basic pricing chart but no order book or liquidity tracker.

I spent most of my time on the Polymarket app for iOS, which holds a 4.7/5 App Store rating. The Android version lags behind at 3.6/5 on Google Play. 

The international app gives you full control over limit orders, order book depth, and position management. The US app covers the basics but lacks these advanced tools.

The US rollout started through a waitlist in December 2025, and access is still granted in stages. You sign up with your phone number and get notified when your spot opens. To skip the waitlist and receive a $20 bonus, use our Polymarket promo code SBR.

Pros and cons

No platform is perfect, and the same goes for Polymarket. It has clear strengths, but there are a few rough edges you should know about.

Pros

• For the global market, there are thousands of active markets at any given time, covering everything from NFL games to Fed rate decisions and Oscar nominees.
• Spreads on headline events are tight. Major political and sports markets regularly show less than 2% between the bid and ask.
• The US version has low fees of 0.10% of the total trade value.
• There is a planned market expansion so that the US version matches the global one.

Cons

• One wrong network selection on a crypto deposit, and the funds are gone. Polymarket cannot reverse blockchain transactions.
• New York and Nevada residents are blocked entirely, and Polymarket US still only covers sports. No politics or financial markets are available yet.
• There are no built-in deposit limits, session timers, or self-exclusion tools on either product.
• There is no phone line. Support is Discord-based internationally and only available via email/in-app chat on Polymarket US. 

Markets available

The range of Polymarket markets on the international variant spans politics, sports, crypto, finance, geopolitics, tech, culture, economy, and weather. Political markets have driven the highest volume historically, and the platform continues to cover global elections and policy decisions.

You will also find short-term crypto contracts, including 15-minute and 5-minute price windows. Also, there is a mention section, similar to Kalshi, where you can predict the words and phrases that will be said.

Polymarket US focuses on sports for now, with active markets across the NFL, NBA, NHL, MLB, MLS, college basketball, tennis, and golf. However, other categories are expected to be covered in the future.

Popular trade types

Most trades on Polymarket involve purchasing either Yes or No contracts. You pick a side, buy shares, and either hold until settlement or sell whenever you want. This flexibility separates it from a sportsbook, where every wager is locked in the moment you place it.

Market variety depends on which version you use. Polymarket US offers game winners, spreads, totals, and futures. The international version goes further with props, crypto price contracts, political outcomes, and a wide range of non-sports markets.

If you prefer to control the price you pay, limit orders are the way to go. They sit on the order book until a counterparty matches them, and they qualify as “maker” orders with no trading fees. This applies to the international version only. Polymarket US doesn't support limit or resting orders yet. 

A lot of experienced users look for markets where they believe the probability is off. Buy shares at a price you think is too low, wait for the market to correct, and sell for the difference.

It basically works the same way as when you spot a mispriced sportsbook line, except you can cash out before the event is over.

Settlement, resolution & payouts

Resolution on the global model runs through the UMA Optimistic Oracle, a decentralized system where the community verifies outcomes. Every market page states its resolution source and exact settlement criteria, so there is no misunderstanding about what counts. 

Once a market reaches its end date, anyone can propose the outcome by posting a proposer bond, usually $750. 

A two-hour challenge window opens after that. If nobody disputes the proposal, the market settles, and payouts go through. If a second dispute comes in, UMA token holders vote on the correct result. 

What matters the most here is the exact wording in the contract. I’ve seen markets where the outcome seemed obvious, but the resolution hinged on a specific phrase in the rules. Disputes are rare, but when they happen, payouts can take a few extra days.

In my experience, standard payouts on undisputed markets arrived in my balance almost immediately after resolution. There is no waiting period or manual review.

Polymarket US handles things differently. Resolution is centralized, and Polymarket determines the final outcome based on the official sources listed in each market’s rules. 

Whichever option you use, always read the full resolution criteria before you start trading. 

Liquidity, odds quality & limits

All liquidity on Polymarket comes from other users. Nobody is making markets behind the scenes. That said, depth has improved a lot over the past few years, with average spreads dropping from around 4.5% in 2023 to roughly 1.2% at the time of writing. 

If you trade a few hundred to a few thousand dollars on a popular market, your order will likely go through right away at the price you see on screen.

Bigger orders require greater caution. Check how much liquidity there is on the books first, because the more you trade, the more the price can move against you.

There are no built-in position or trade-size limits in either version. Polymarket runs a Maker Rebates program that pays daily USDC rebates to liquidity providers on select markets. This helps keep the books deep and spreads light. 

Customer support & trust signals

If you run into an issue on the global version, Discord is the main support channel. Response times vary, but the community is active, and moderators are generally helpful.

Don’t forget that the global product is non-custodial. You hold your own wallet and private keys, and Polymarket has no way to recover funds if you lose access. Their Help Center also warns that staff will never DM you first or ask for sensitive credentials, so keep that in mind in case someone reaches out. 

Polymarket US offers a more traditional support setup with email (support@polymarket.us) and in-app chat. For users who prefer direct communication, this is a clear advantage over the international model.

From a credibility standpoint, the CTFC-regulated US entity and the backing from Intercontinental Exchange carry real weight, especially considering they also own the New York Stock Exchange. Few prediction market platforms can match that level of institutional validation.

Fees, funding & withdrawals

One of the biggest differences between the international and US versions of Polymarket is how fees are handled. I break it all down below.

International Polymarket fees

Since March 30, 2026, taker fees apply to nearly every market category on the international format. The fee structure uses a dynamic curve that peaks when the probability is at 50% and drops as prices move toward either extreme. 

At peak, crypto markets carry the highest rate at 1.80%, followed by economics, culture, weather, and general markets at 1.25%. Politics, finance, tech, and mentions come in at 1.00%, and sports sit at 0.75%. Geopolitics is the only category with zero fees. 

Maker orders are always free. Polymarket also doesn’t charge its users anything when they deposit or withdraw USDC, but the third-party services like Coinbase or MoonPay will apply their own charges. 

US Polymarket fees

The US counterpart uses a simpler flat-rate model. Taker orders pay 0.30% on the total contract premium, while maker orders earn a 0.20% rebate. All fees round to the nearest $0.0010.

The easiest way to cut costs across both variations is to use limit orders exclusively. Patient traders who set their own prices will always pay less than those who hit the best available offer.

Is Polymarket legal?

If you are wondering if Polymarket is legal, the short answer is yes. However, the full story involves a significant enforcement action and a complete regulatory turnaround.

In January 2022, the CFTC charged Polymarket with offering unregistered binary options. The platform settled and paid a $1.4 million penalty, and US users were blocked from accessing it. 

That changed in July 2025 when the CTFC and DOJ closed their investigations without new charges. Polymarket then acquired QCEX (a CFTC-licensed exchange and clearinghouse) for $112 million. 

By November 2025, the CFTC had granted Polymarket an Amended Order of Designation as a fully regulated DCM. US users can now once again trade through commission merchants and licensed brokers.

Polymarket US launched its app in December 2025 and is available in almost all states. Only New York and Nevada have restricted access. In addition, some individual states have opened separate court cases over whether prediction markets fall under state gambling jurisdiction.

Polymarket bonuses & promotions

Right now, new users at Polymarket can take advantage of $20 in bonuses after inputting Polymarket promo code SBR and depositing at least $20. This Polymarket invite code will also allow new users to skip the waitlist. This is a great offer, even when compared to other great bonuses, such as those you'll get from the Fanatics Markets promo code, Crypto.com promo code, and DraftKings Predictions promo code.

The global variant runs a liquidity rewards program, which pays USDC rebates to users who place competitive limit orders and keep markets active. This is geared toward experienced traders who want to earn from providing depth, not a casual onboarding perk.

Polymarket vs. sportsbooks

The biggest difference between Polymarket and the U.S. betting sites is who you are trading against. A sportsbook sets the odds and takes the other side of every wager, whereas Polymarket removes that entirely. Prices come from an open order book, and every trade matches you directly with another user.

That peer-to-peer setup also means you are not locked in once you buy. Sportsbook bets are usually final the moment you place them, but on Polymarket, you can sell your shares whenever the price moves in your favor (or cut your losses early). 

Promotional offers look different, too. Sportsbooks hand out deposit matches and bonus bets worth hundreds of dollars. Polymarket keeps things small, with occasional sign up credits and referral bonuses to help new users get started.

Where it pulls ahead is market selection, especially on the international platform. You can trade on politics, macroeconomic data, tech milestones, and cultural events that most sportsbooks will never list.

Who should use Polymarket?

Best for: Sportsbook users who want peer-to-peer pricing without a house edge, cost-conscious traders who value low fees, and crypto-native users who want access to politics, finance, and culture markets on the international version.

Not ideal for: Users who need limit orders or advanced trading tools (not available on Polymarket US), people who want desktop access, and anyone who expects full responsible-gambling features like deposit limits, self-exclusion, or phone support.

Banking / deposits & withdrawals

Funding the global product means working with USDC on the Polygon network. The cheapest way is to buy USDC on an exchange and send it directly to your Polymarket deposit address. Network fees are fractions of a cent.

If you don’t hold crypto, you can get it through MoonPay using a credit or debit card. It’s convenient, but expect a 1–4% fee on top. I used this method for my first deposit and had funds in my account within a couple of minutes.

The Polymarket withdrawal process is just as quick. Pick a recipient address, choose the token and network, and confirm. Polymarket doesn’t take a cut, but the receiving exchange might. Double-check the network before you send. 

Polymarket US skips all of that. Deposit with a debit card, bank transfer (ACH), Apple Pay, or wire transfer through the app, and everything runs in US dollars. No wallet, no USDC, no network selection. If you have never used crypto before, this is the easiest entry point by far.

Responsible trading / risk warning

Every contract on Polymarket is all-or-nothing. If your prediction is wrong, you lose the full amount you put in.

With the international variant, you also need to secure your own wallet, keys, and password. Lose access, and there is no way to get your funds back. The US one removes that concern since it operates as a fiat-based, regulated exchange, but the trading risk itself remains the same.

Neither site currently offers deposit limits, loss limits, self-exclusion, or cooling-off tools, like regulated sportsbooks do. Set your own boundaries before you start and treat any promo credits as a way to learn, not a guaranteed return.
