Polymarket Overview

Polymarket is the world's largest prediction market by trading volume. It has processed more than $3 billion in trades since launching in 2020. The platform runs on the Polygon blockchain. All positions settle in USDC. It is fully decentralised. No company holds your funds. Market outcomes are decided by the UMA Protocol oracle, not by Polymarket's own team.

Polymarket became famous during the 2024 US presidential election. Major polls kept underestimating Donald Trump's chances. Polymarket had his odds at 55-65% in the final weeks. That turned out to be accurate. The result brought millions of new users to the platform and major media coverage worldwide. Prediction markets were suddenly taken seriously as a forecasting tool.

One important note for US readers: Polymarket is blocked for US users. In 2022, Polymarket paid a $1.4 million CFTC fine and agreed to block all US access. You cannot legally use Polymarket from the United States. US residents should read our Kalshi review or Robinhood Predict review instead. If you are in the UK, Canada, Australia, or most other countries, Polymarket is the best prediction market available.

Polymarket App Review

iOS App

Not available

Android App

Not available

Polymarket does not have a native iOS or Android app as of 2026. All access is through a web browser. The mobile experience is excellent. The interface is fully responsive and loads fast on mobile data. You can browse markets, place orders, manage positions, and withdraw funds from your phone. Add Polymarket to your home screen as a PWA for a quick shortcut. Polymarket has mentioned plans for a native app, but none has launched at the time of this review.

Our Verdict

4.8/5

Polymarket

Polymarket is the best prediction market in the world for anyone outside the United States. No other platform has deeper liquidity, more markets, or a better trading experience. Setting up a crypto wallet takes effort if you have never done it before. But it is a one-time task and the setup guides are clear. There are no per-trade maker fees. The market range is exceptional. If you are a US resident, Polymarket is not a legal option. Read our Kalshi review or Robinhood Predict review for regulated US alternatives. If you are anywhere else in the world, Polymarket is where you should be trading.

Frequently Asked Questions

Is Polymarket legal in the US?
No. Polymarket is blocked for US users. In 2022, Polymarket paid a $1.4 million CFTC fine and blocked all US IP addresses. Using a VPN to access it breaks Polymarket's terms of service and may break US law. US residents should use Kalshi or Robinhood Predict instead. Both are CFTC-regulated and fully legal.
How do I start trading on Polymarket?
You need two things to start. First, a Web3 wallet. MetaMask, Rainbow, and Coinbase Wallet all work. Second, USDC on the Polygon network. Connect your wallet at polymarket.com and browse the markets. Your wallet address is your account. There is no email or password. The easiest way to get USDC on Polygon is to withdraw from Coinbase or Binance using their Polygon network option.
What fees does Polymarket charge?
Polymarket charges no maker fees. Taker fees are typically 1-2% on market orders. The exact fee varies by market. There is no house margin built into prices. Prices are set by traders and reflect real probability estimates. This makes Polymarket much cheaper to use than most competitors. Sportsbook-style platforms embed a 5-10% margin into every market.
How does Polymarket resolve markets?
Polymarket uses the UMA Protocol oracle to settle markets. When a market closes, a resolution is submitted with a bond. That resolution has a 48-hour challenge window. If no one disputes it, it goes through automatically. If disputed, UMA token holders vote on the outcome. The system has a strong track record. Some markets with unclear wording have been disputed and took longer to settle.
Is Polymarket safe to use?
Polymarket's smart contracts have been externally audited and have a strong security record since 2020. It is non-custodial. Your USDC stays in your wallet until you place a trade. There is no central fund pool for hackers to target. Polymarket is not regulated. There is no FSCS, FDIC, or similar protection. If Polymarket shut down, recovering your funds is not guaranteed. Only keep on the platform what you are actively trading.
Can I use Polymarket on mobile?
Yes. Polymarket works well on iOS and Android in a mobile browser. The interface is fully responsive. All trading features work on your phone. There is no native app. Add Polymarket to your home screen as a PWA for a quick shortcut. Polymarket has mentioned plans for a native app, but as of 2026 it is browser-only.
What is the minimum deposit on Polymarket?
There is no official minimum deposit. You can add any amount of USDC. In practice, Polygon gas fees apply to each trade. These are usually $0.01-0.05 per transaction. Very small deposits are not efficient. A starting balance of $20-50 USDC works well for most trades. Most active traders keep at least $100 on the platform.
