Verdict
Both are non-custodial on-chain markets with a free maker side. Polymarket is far larger and scores higher on our model; Predict.fun publishes one of the cheapest and best-documented taker schedules we have read, but names no licence and blocks the US, UK, France and Australia.
Row by row
The edge on each row is marked. Built automatically from the platform records, so it never drifts from the reviews — rows that describe rather than rank, like jurisdiction or market categories, say “no edge” instead of picking a side.

| Fee conditions & evidence | Taker fee = shares × category rate × price × (1 − price). For 100 crypto shares at $0.50 with rate 0.07, the fee is $1.75 on a $50 purchase: 3.5% of purchase cost, not 1.75%. Rounding and any rebates must be considered separately. Review evidence · Official fee source | Makers pay no fee. The published taker formula uses the base rate × min(price, 1 − price) × shares, with an optional discount. The documented 1 USDT minimum is an order minimum, not a verified deposit minimum. Review evidence · Official fee source | Depends on the trade |
