Polymarket Review

Best for: Political & News Forecasting

After several weeks of testing Polymarket, our reviewers found it easy to see why it has become a central hub for prediction trading. It offers a fundamentally different experience than a traditional sportsbook; instead of betting against a house and its built-in "vig," you trade shares in real-world outcomes directly with other users on an exchange, turning questions about the future into a live, price-driven market.

Backed by a $2 billion strategic investment from Intercontinental Exchange, the parent company of the New York Stock Exchange, Polymarket has successfully bridged the gap between crypto-native trading and mainstream finance. 

While the general public is currently staring at a waitlist of over 1 million users, our partnership lets you bypass the queue entirely. By entering our exclusive invite code GAMBLING during signup, you can skip the line for instant access to the most liquid and sophisticated event-trading platform we have reviewed to date. You’ll also get a $20 bonus match when you deposit $20.

Who is Polymarket?

How are they regulated?

To get a handle on why Polymarket is even allowed back in the States, you have to look at its bumpy road to regulation. Polymarket secured its U.S. foothold by acquiring QCX LLC, a regulated exchange and clearinghouse. This allows the U.S. version of the site to operate as a Designated Contract Market (DCM) under the full federal oversight of the Commodity Futures Trading Commission (CFTC).

This regulatory shift has brought significant institutional muscle to the table, including a nearly $2 billion investment from the owners of the New York Stock Exchange and official partnerships with major leagues such as the MLB, NHL, and UFC.

Where are they Available?

Because it’s regulated at the federal level, Polymarket is technically authorized to operate nationwide. However, as of May 2026, the platform is not available in Nevada due to a temporary restraining order obtained by the Nevada Gaming Control Board (NGCB). The ruling is based on Nevada regulators' argument that Polymarket's event contracts constitute sports betting and that the operator does not hold a state license.   

Polymarket also faces regulatory scrutiny in other states, such as Massachusetts and New Jersey, though no rulings currently prohibit its operations in those states.

Users must be at least 18 years old and physically located in an eligible state to participate.

What Markets do They Offer?

The variety of markets is what sets this platform apart from a standard sports betting app. While we found deep liquidity in the sports section, covering over 15 sports, including the NFL, NBA, and even chess, the platform is best known for its political and economic markets.

You can trade on anything from the daily high temperature in a particular city and election winners to "mention markets," live events where users predict which words and phrases will be said. The platform performs best during major news cycles, as prices react almost instantly to breaking information.

How Does It Work?

At its core, Polymarket is refreshingly simple: everything boils down to a “Yes” or “No” share. The platform feels more like a professional trading desk than a betting site, with live order books and volume charts that let you see exactly where the money is moving.

Because it runs on the Polygon blockchain, every trade is recorded on a public ledger, providing transparency that traditional sportsbooks simply don't offer.

How to Trade

When you buy in, you’re picking up “shares” of an outcome, with prices that constantly fluctuate between $0.01 and $0.99 based on how other traders respond to the news cycle. This price is effectively the market’s way of showing you the probability of the outcome; for example, a price of $0.65 implies that the market sees a 65% chance of that event occurring; if your prediction is right, each share pays out exactly $1.00.

One of the biggest advantages is that you aren't locked into a position; you can sell your shares back to the market at any time before the event ends to lock in a profit or cut your losses.

Fees & Payment Methods

In March 2026, the U.S. platform shifted to a variable fee model where takers (market orders) pay a percentage-based fee that scales with contract pricing, while makers (limit orders) receive a rebate on filled trades.

To put that into perspective, this means taker fees can reach around $1.25 per 100 contracts at the $0.50 price level, while makers may earn roughly a 1.25% rebate for providing liquidity. In our testing, this structure resulted in fees roughly 30% lower than Kalshi's fees on comparable trades.

Funding is straightforward for U.S. users; we used debit cards, bank transfers, and wire transfers. The platform handles conversions to the USDC behind the scenes.

Special Features

The platform is built for fast-paced trading, and we were particularly impressed with the "Breaking News" tab, which links current headlines directly to related markets.

You can also track your performance against the community on a global leaderboard that ranks traders by profit over different timeframes.

While there isn't currently an option to earn interest on idle balances, features like biometric logins and real-time order books give the app a professional, finance-oriented feel.

Promotions

Welcome Offer

New users in the U.S. can grab a $20 trading bonus after they complete their first trade of at least $10. The main hurdle right now for most eager traders is a long waitlist, but using our invite code GAMBLING lets you skip the line and gain immediate access to trading.

Just keep in mind that the bonus credit is non-withdrawable until you’ve cleared it through trading activity on the platform. There are no other conditions related to the bonus as long as you’re old enough to sign up (18+) and you’re a new customer.

Ongoing Offers

Polymarket doesn't really do "boosts" like a sportsbook, but it does distribute liquidity rewards. If you’re active with limit orders near the market midpoint, you earn a share of a daily reward pool, which essentially pays you to help keep the markets balanced. 

App & Site User Experience

When comparing the two mobile versions, the iOS app appears to be the superior product, with user ratings (4.7 at the time of review) supporting this view. During testing, our experts found it snappy and simple to navigate.

The Android app feels less polished, with users occasionally reporting bugs and slower performance. A considerably lower Google Play rating of 1.9 (as of May 2026) reflects these issues.

For U.S. users, the desktop site can be used for browsing and researching markets in "view-mode," but you’ll need to use the mobile app to execute trades. From our perspective, this is not ideal because it can be frustrating to have to switch to a mobile app to execute a trade after doing your research on a large monitor. 

We also observed that the desktop “view mode” displays a substantially larger number of markets than the Polymarket app. When we clicked “More” in the app, a message appeared stating, “More polymarkets coming soon.”

How Polymarket Compares to Other Prediction Market Apps

Compared to Kalshi, Polymarket often has lower taker fees and higher maker rebates. However, Kalshi pays an APY of 3-4% on your balance, which Polymarket does not.

Against traditional U.S. sportsbooks, Polymarket often offers better price value by removing built-in “vig,” but you won't find the same depth of player props or parlay builders that sites like FanDuel or DraftKings offer.
 

Safety & Responsibility Measures

Sign-Up & Account Verification

Because this is a regulated platform, we had to go through a standard KYC (Know Your Customer) process to sign up. This involved uploading a government-issued photo ID and a selfie, which in our testing typically cleared in about 24 to 48 hours.

Follow these step-by-step guidelines for getting started and claiming your welcome bonus:

1. Click our link on your mobile device: This is important. You must open the sign-up link below on your mobile device. The promo code field is only available through mobile, so desktop users will miss out.
2. Create your account: Enter your name and address, then follow the onboarding instructions.
3. Enter promo code: When prompted for a promo code during sign-up, enter GAMBLING. This is what unlocks your waitlist skip and triggers the bonus.
4. Make your $20 deposit: Fund your account with at least $20 to qualify for the $20 bonus.
5. Start trading

The app itself feels secure, using on-chain settlement and supporting biometric security to protect your account.

The Settlement Question: US vs. International

While the U.S. platform is highly secure, it is important to distinguish its settlement process from the international version of Polymarket. In the US, outcomes are decided by an internal Markets Team based on official data, which we found to be reliable and straightforward.

However, the international site uses a decentralized system called the UMA Optimistic Oracle, which relies on token-holder voting. This has led to documented "whale manipulation" issues, in which wealthy traders use their massive voting power to force a specific outcome regardless of the actual event results.

As a U.S. trader, you are not exposed to this “token-voting” risk because in the U.S. version of Polymarket, “the Exchange determines the result using publicly verifiable information.” Nonetheless, it’s a critical factor to keep in mind when analyzing global market sentiment.

Responsible Trading

The most disappointing discovery was the lack of safety tools. There are currently no options to set your own deposit limits, cooling-off periods, or self-exclusion, which is a major shortcoming compared to regulated sportsbooks.

By comparison, Kalshi does have a “responsible trading” section. It also offers the aforementioned tools to set deposit limits and opt into self-exclusion. 

Our Final Verdict on Polymarket

If you want to treat event trading as a professional discipline, Polymarket is currently one of the most sophisticated and liquid prediction market apps available. While the U.S. version is still in a phased rollout and lacks some of the safety tools we’d like to see, the ability to trade with lower fees and earn maker rebates makes it a top-tier choice.
