OpinionOpinion arbitrage: fees, depth and live spreads

Opinion groups markets into topics, such as a token's valuation after launch, with one child market per threshold or outcome. Each child is a YES/NO market with its own order book. The child's name on its own ("$50M", "December 31, 2026") only makes sense together with the topic, which is how the scanner matches it.
Fees and headline volume
Opinion charges takers a fee and pays rebates, but the per-market rate isn't in the public data we read. ArbSonar applies an estimate of 0.04 × P × (1 − P) per share. Check the ticket before trading.
Third-party volume figures for Opinion vary widely and some analysts have questioned them. For arbitrage, ignore headline volume and look at the order book: the size at the best ask is what limits your trade.
Where Opinion spreads come from
Most Opinion spreads pair with Polymarket on crypto launches and macro questions, where both venues list the same thresholds. Depth on Opinion is often small, so large ROI can mean only a few dollars of real profit. The scanner shows the depth-capped number.
