Prediction Market Trading Fees

Prediction market trading fees are how an event-contract exchange earns revenue, and they differ structurally from a sportsbook house edge. Instead of building a margin into the odds, a prediction-market venue charges an explicit fee on activity. Common designs include a maker-taker schedule, a charge embedded in the spread, or a settlement fee applied to volume at market resolution. Because the venue is a neutral exchange matching buyers and sellers of outcome shares, its income comes from facilitating trades rather than from being the counterparty to every bet.

In a maker-taker model, a participant who posts a resting limit order that adds depth to the book is the maker, while a participant who crosses the spread to fill an existing order is the taker. Takers usually pay a higher fee, and makers pay a lower fee or sometimes earn a rebate, because their resting orders supply the prediction market liquidity that other traders rely on. Fee design therefore shapes behavior. A schedule that rewards makers tightens spreads and deepens the order book, whereas a flat or taker-heavy fee can discourage the very liquidity provision the venue needs.

These fees matter to affiliate programs because they define the revenue pool that funds partner payouts. Under revshare, an affiliate earns a percentage of the net fee revenue generated by the traders they refer, so the venue's effective fee rate and a referred trader's volume together determine ongoing prediction market commission. This is the prediction-market analog of sportsbook revshare paid on net gaming revenue, except the base is transparent trading-fee income rather than the implied take captured through vigorish.

For operators choosing between commission structures, fee design and affiliate economics are linked. A maker-rebate model can suppress headline fee revenue while building the liquidity that drives long-term volume, which favors patient revshare arrangements over front-loaded payouts. Comparing the two approaches is the core of any CPA vs revshare decision for prediction markets, and managing those payout terms against measured fee revenue is exactly what structured commission management is built to support.
