Underdog fees explained

Trading fees

Underdog builds its margin into its payout structure rather than charging a separate per-contract fee, which keeps the cost simple to read. Its signature multi-pick entries combine several predictions into one, so it helps to think about cost at the entry level rather than per contract.

With parlay-style entries, your effective cost and payout are driven by how many picks you combine and at what prices.

Funding costs

Because Underdog funds in US dollars through standard methods, depositing and withdrawing is generally straightforward and low-cost, with no crypto network fees to worry about. See the deposit and withdraw guides for the exact funding steps and timing.

How it compares

No prediction market is truly free to trade — the cost simply shows up differently from one platform to the next, whether as an explicit per-contract fee, a spread baked into prices, or a built-in margin. To weigh Underdog against the rest, see the platform rankings, the lowest-fee platforms roundup, and the cross-platform profit calculator, which lets you factor any fee into a trade to see your real ROI. And remember that fees are not the only cost of trading — see our guide to taxes on prediction-market winnings.
