Coinbase fees explained

Trading fees

Because Coinbase routes prediction markets through Kalshi’s regulated exchange, trading costs are among the lowest available — typically a small per-contract fee rather than a wide spread. Moving money in and out uses Coinbase’s standard funding rails.

Crypto-native traders can keep funds as crypto between trades and only convert what they actually need to deploy.

Funding costs

Funding is integrated with your Coinbase balance, so moving money in and out is generally low-cost, with none of the friction of opening and funding a separate account. 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 Coinbase 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.
