Polymarket Review

Polymarket summary

At Polymarket, users buy 'Yes' or 'No' contracts priced between $0.01 and $0.99 on real-world events. Winning shares pay out $1 each, while losing shares settle at $0. Markets span across sports, politics, crypto, finance, culture, and more.

To get started on the platform, new users can enter the Polymarket promo code SBR to earn $50 in bonuses. A minimum deposit of $20 is required.

Polymarket offers the full range of categories with trades settled in USDC on the Polygon blockchain. In the US, deposits are available through crypto, ACH, wire transfer, debit card, and Apple Pay. There is also a native app on both iOS and Android.

What is Polymarket?

Every market on Polymarket is an event contract tied to a real-world event. Users buy either the 'Yes' or 'No' side of the market. Each share trades between $0.01 and $0.99, and the price reflects the market's estimate of the probability of a specific outcome. The closer a share is to $1.00, the more likely the market considers that outcome to be the result. 

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. 

This 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.

Let's 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 a small profit. You can also add more shares if you think the price remains favorable for the expected outcome.

Some sportsbooks offer Early Cash Out options, too, but you have to give up part of your potential payout to use them. They also limit when the option is even available. With Polymarket, you'll get a fair market price, and you always have the option to sell your position early. 

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. As we highlight later in our Polymarket review, its prices are sourced directly from the order book with no markup.

Polymarket offers one of the best prediction market promos: $50 in bonuses after making a deposit of at least $20. Check out how it compares to other great offers in the industry, such as the ones available via the Kalshi promo code, OG promo code, Robinhood promo code, and FanDuel Predicts promo code.

How Polymarket works

Users in the US will find that registering for Polymarket and making their first trade takes less than five minutes. Here's how to get started.

1. Create your account: Download the app or register on your desktop, then enter personal information and complete KYC verification.
2. Add funds: Polymarket allows deposits via crypto, a debit card, or bank transfer. However, the platform supports only crypto withdrawals.
3. Find a market: Browse the categories or search for a specific event. Every listing shows the current price, which tells you the estimated probability of the contract resolving correctly.
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

Before writing this Polymarket review, I spent more than five hours exploring the platform. I created my account, deposited funds, and made ten trades in total, with five of them settling as correct outcomes.

Here's the good and the bad of my experience.

Website and Polymarket app experience

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

I spent most of my time on the Polymarket app for iOS, which holds a 4.6/5.0 rating on the App Store. The Android version holds the same 4.6/5.0 rating on Google Play. 

The U.S. rollout started through a waitlist in December 2025, and access was granted in stages. However, the waitlist has since been removed.

Polymarket 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

• Multiple Markets: Polymarket offers plenty of markets related to sports, politics, tech, the economy, and more.
• Solid Pricing: Spreads on headline events are tight. Major political and sports markets regularly show less than 2% between the bid and ask.
• Availability: Polymarket is legal in all states, plus DC.

Cons

• Crypto Learning Curve: One wrong network selection on a crypto deposit, and the funds are gone. Polymarket cannot reverse blockchain transactions.
• Responsible Trading Tools: There are no built-in deposit limits, session timers, or self-exclusion tools on either product.
• Customer Support Limitations: No phone support. Support is only available via email/in-app chat.

Markets available

The range of Polymarket markets 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.

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.

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.

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

At Polymarket, resolution is centralized, and the platform determines the final outcome based on the official sources listed in each market’s rules. Once resolution is finalized, the payout will generally arrive in your account in minutes.

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

Polymarket offers a more traditional support setup with email (support@polymarket.us) and in-app chat. 

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.

Polymarket fees

Polymarket uses the following formula to determine fees: Θ × C × p × (1 − p). Essentially, this means that takers pay the most in fees around the 50-cent mark, while fees decrease the closer they get to $0.01 and $0.99. While this complicated formula may seem like a lot, it actually produces some of the best fees of any prediction market app. Fees at Polymarket tend to be significantly better than at Kalshi.

Is Polymarket legal?

Yes, Polymarket is legal. Polymarket launched its app in the United States in December 2025, and it is available in most states. In response, some states have launched legal battles against Polymarket and the CFTC over whether prediction markets should fall under state gambling laws. Those cases are ongoing and far from settled.

These types of legal battles are nothing new for Polymarket. 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. American users can now once again trade through commission merchants and licensed brokers.

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading involves high risk and may result in loss of your entire investment. See http://polymarket.us/tos  for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated derivatives exchange and clearing organization.

Comparing Polymarket US to the global version

The international version of Polymarket functions similarly to the US version, but there are also some key differences. 

Registration and deposit methods

To register for the international version of Polymarket, you need to sign up through Google, email, or a crypto wallet. Adding funds means depositing USDC on Polygon from a crypto exchange or buying it directly through MoonPay's card on-ramp system. This is much more limiting than what the Us version allows. 

Market availability

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. The international version also includes plenty of player props, crypto price contracts, political outcomes, and a wide range of non-sports markets.

Fees

Since early 2026, taker fees have applied to nearly every market category on the international format. The fee structure uses a dynamic curve that peaks at 50% probability and declines 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 may apply their own charges. 

Resolution and disputes

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.

Customer support

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. 

Welcome bonus

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 bonuses & promotions

Right now, new users at Polymarket can take advantage of $50 in bonuses after inputting Polymarket invite code SBR and making a deposit of at least $20. 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.

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.

Not ideal for: Anyone who expects full responsible-gambling features like deposit limits, self-exclusion, or phone support.

Polymarket banking options

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. 

While Polymarket US used to operate with US dollars, it now only supports withdrawals via a Polygon-supported address. This can make it difficult for users who are unfamiliar with crypto to get their earnings, especially if they deposited with fiat options. If crypto isn't your thing, you may want to check out some great apps like Polymarket, as they may suit you better.

Responsible trading on Polymarket

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.

Whether you consider prediction markets to be the same as online sportsbooks or not (the jury is still out), one thing is certain: the risk of losing money is very real. If you're concerned about your trading habits, please call a national helpline at 1-800-GAMBLER or 1-800-MYRESET.
