Polymarket Review
"The world largest prediction market by trading volume"
Polymarket is the largest prediction market in the world by trading volume. Built on blockchain technology, it offers zero trading fees and unmatched global liquidity on major political and sports events.
Overview
Fee Structure
No trading fees. Earn from market making. Requires USDC cryptocurrency to trade.
Fee drag example: A 0% fee means on a $100 trade you pay $0.00 immediately. To break even on a 50/50 market you need to be right roughly 50.0% of the time — before transaction costs compound over multiple trades.

Our Verdict
Polymarket is best for: Crypto-native traders who want global liquidity and zero fees. At 0% per trade, factor fee drag into any participation strategy.
Responsible Participation
Prediction markets involve real financial risk. Trading fees erode returns on every transaction. Information asymmetry significantly disadvantages retail participants. Treat these platforms as speculative entertainment — not income or investment. Never trade with money you cannot afford to lose entirely.
