Opinion review
A BNB Chain venue built around macro and political markets, with the lowest maximum taker fee in the series, 1% at 50¢, and an AI oracle whose results anyone can dispute by staking its OPN token. Its January 2026 volume drew public questions about wash trading, and DefiLlama filters flagged wallets out of its figure.

How to start safely
- Check that you are allowed to trade
Read the excluded countries on the card. If yours is listed, do not trade there: platforms such as Polymarket forbid getting around their blocks with a VPN in their terms.
- Open the official site yourself
Type opinion.trade or use a bookmark: fake prediction market sites and “airdrop” pages are common and drain wallets.
- Read the market rules
Every market names its resolution source and its end date. A contract pays on what those rules say, not on what the headline says.
- Start small and mind the fee
Fee formulas peak around 50¢. A limit order that waits in the book usually pays less than one that takes the best price, and often nothing.
