Our verdict
Polymarket suits people who want to trade event shares across a very broad list of markets, from sports and politics to geopolitics, and who accept the risk of losing the full stake. The trade-offs: legal status differs by country and US state, several countries have blocked or restricted it, and some US reviewers report slow withdrawals and hard-to-reach support.
Best for: People who want to trade event shares across many topics, including geopolitics (fee-free markets)
Skip it if: People in restricted countries or states; the official docs list many places where only closing positions is allowed
Pros
- Very wide market range: sports, elections, finance, weather, culture, crypto
- Fees published in the docs; makers pay nothing and geopolitical markets are fee-free
- No house as counterparty: per the help center, the counterparty to each trade is another user
Cons
- The 4.6/5 App Store score covers the US app, and recent reviews mention slow withdrawals, account holds for identity checks and slow support replies
- Many countries block or restrict it; the official docs list France, Germany, Italy, Australia, Brazil, Belgium and others as close-only
All pros and cons · Who is it for?
Pros
- Detailed API documentation for developers
Cons
- The legal position moves quickly; the app listing says trading is unavailable in Nevada and not available in all jurisdictions
Best for
- Developers who need an API and docs for market data or order placement
Skip it if
- Anyone who cannot accept losing the entire stake

Experience & key features
What it is
Polymarket is a prediction market platform where users buy and sell shares in the outcome of future events. Per its help center, prices sit between 0 and 1 USDC, each pair of Yes and No shares is collateralised by 1 USDC, and the correct shares pay 1 USDC when the market resolves. Wikipedia says Shayne Coplan founded the company in New York in June 2020. There is a global site at polymarket.com and a US version at polymarket.us with its own app.
How trading and fees work
Prices equal probabilities: per the help center, an 18-cent price means the market implies an 18% chance. Users can sell before the outcome is known. According to the official docs, only takers pay fees, at 0.04 to 0.07 depending on category, while makers pay nothing and geopolitical markets are fee-free. Part of the taker fees funds daily rebates to makers.
Legal status
According to Wikipedia's summary, in January 2022 the CFTC fined Polymarket $1.4 million and the company stopped serving US customers; in November 2024 the FBI raided the founder's home; in July 2025 the DOJ and CFTC ended their investigations and Polymarket announced a $112 million acquisition of QCEX, a CFTC-licensed exchange. Wikipedia also lists multiple countries blocking access in 2025 and 2026. The official docs say Polymarket restricts order placement from certain regions, with many countries set to close-only. This is a secondary source and the situation changes quickly, so check the rules where you live.

How it compares
Polymarket and Kalshi are both prediction markets. The difference is that Polymarket started as a USDC-based platform open globally where not restricted, whereas Kalshi is a CFTC-regulated exchange aimed at US users. For conventional crypto trading, Coinbase is another option.

Plans & pricing
Prices last verified Nov 10, 2026
Tài khoản tiêu chuẩn (phí theo giao dịch)
PersonalFree
Per the official documentation, Polymarket charges only takers, using fee = shares × fee rate × price × (1 − price). Taker rates are 0.07 for crypto; 0.05 for sports, economics, culture, weather, other and combos; and 0.04 for finance, politics, tech and mentions. Geopolitical markets are fee-free, and makers are never charged. For example, 100 crypto shares at a $0.50 price carry the peak fee of $1.75. Polymarket charges no fee to deposit or withdraw USDC, though intermediaries such as Coinbase or MoonPay may charge their own.
- Free plan limits
- Event shares are priced between $0 and $1, and winning shares pay $1 when the market resolves. On the US app, the App Store listing cites debit card or bank-transfer funding and warns that trading may result in loss of the entire investment.
- Free trial
- No free trial
Cancellation & refunds
Not applicable, as there is no paid plan. Winning shares pay out on the market's final resolution.
Privacy
Per the App Store privacy label (self-declared, not verified by Apple), the app may use identifiers and usage data to track you across other companies' apps and websites, and device-ID identifiers are linked to your identity. The privacy policy is at polymarket.com/privacy; AppDuo could not open it during research (the connection was reset) and so did not cross-check it. Read it, especially the parts on identity verification and data sharing, before signing up.

Why this score
The price-equals-probability mechanic is simple and the App Store rating is 4.6/5 from over 65,000 ratings. Points are lost for having two versions (global and US) complaints about identity checks, and an English-only interface.
Why this score
A wide range of market topics, live in-game trading, combos, an API and a daily maker rebate program. Comparable in breadth to Kalshi.
Why this score
Taker rates of 0.04 to 0.07 under a published formula, peaking at $1.75 per 100 shares at the 0.07 rate; makers and geopolitical markets pay nothing; no Polymarket fee on USDC deposits or withdrawals.
Why this score
No independent uptime data. The docs include a section on matching-engine restarts and announce the shutdown of RTDS price feeds on 30 November 2026, showing the stack is still changing.
Why this score
The App Store listing advertises 24/7 live support, and developer replies point to [email protected]. Several recent reviews, however, complain of unresponsive support and slow withdrawals.
Why this score
The App Store label declares identifiers and usage data used for tracking, with device IDs tied to identity. The full privacy policy could not be opened.
