Polymarket Review
The world's largest prediction market, where you trade on real-world events with crypto. Independent Polymarket review: 4.2/5 for prediction markets.

Our verdict
Traders already comfortable with crypto are the fit: Polymarket settles in USDC on the Polygon blockchain, and you hold your own funds in a self-custody wallet. Liquidity is deep on high-profile election markets. The friction is getting in, since you need a crypto wallet and USDC on Polygon, and it's restricted in several U.S. states, which keeps it from rating higher.
Skip it if you don't want to set up a crypto wallet, or live in a restricted U.S. state.
