Jupiter Predict fees depend on the market type. The current fee rates in the app take precedence over this page. Quoted amounts are estimates; final costs depend on the trades that fill and the fees that apply. ## How are trading fees charged? When buying or selling contracts: * Trading fees apply only to the part of your order that fills. An order with no fills has no trading fee. * For an open buy limit order, funds for the unfilled portion stay reserved. Unused funds are returned when the order closes. * On Polymarket markets, trades settle in JupUSD. If you pay with another token, it is swapped to JupUSD first. Swap costs and Solana network costs are separate from trading fees. * Claiming winnings from a Polymarket position has no additional trading fee. Fees already paid on filled trades are not refunded. Returning unused order funds also has no trading fee. Arcade uses a different fee model, explained [below](#how-does-the-arcade-fee-work). ## What fee does each market type charge? | Market type | Trading fee | | - | - | | Polymarket-sourced markets on Browse | The applicable Polymarket platform fee plus a Jupiter builder fee, currently 2% of trade value. See [How are fees on Polymarket markets calculated?](#how-are-fees-on-polymarket-markets-calculated) | | Sports ticket markets | Currently no trading fees. See [Sports markets](https://docs.jup.ag/user-docs/trade/predict/sports-markets.md#what-are-ticket-markets) | | Jupiter Forecast markets (SPCX on Degen) | Currently no trading fees, shown with a No fees badge. See [Degen](https://docs.jup.ag/user-docs/trade/predict/degen.md#what-are-jupiter-forecast-markets) | | Other Degen markets | Set by the market's route. The quote shows the fee before you sign | | Arcade rounds | 1% of the payout, taken only when you win. See [How does the Arcade fee work?](#how-does-the-arcade-fee-work) | ## How are fees on Polymarket markets calculated? For standard Jupiter trades on Polymarket-sourced markets, trading fees have two parts: | Fee | When it applies | | - | - | | Polymarket platform fee | Applies to taker fills on markets where Polymarket charges fees. It depends on the market, execution price, and number of contracts filled. Maker fills have no platform fee. | | Jupiter builder fee | Currently 2% of trade value on both buys and sells, for both maker and taker fills. It also applies on markets with no Polymarket platform fee. | Trade value is the number of contracts filled multiplied by their execution price, before fees. The builder fee is based on this value, not your profit or potential payout. A taker trade fills against an available order. A maker trade comes from an order that waits on the order book until another trader fills it. A limit order can fill immediately as a taker, so choosing a limit order does not guarantee zero platform fees. If part fills immediately and the rest fills later as a maker, each part is charged according to how it fills. Polymarket's platform fee varies by market and execution price; see [Polymarket's fee schedule](https://docs.polymarket.com/trading/fees). Jupiter's builder fee is added separately. For example, buying 100 contracts at \$0.25 has a trade value of \$25. The builder fee is \$0.50, so the total cost is \$25.50 plus any applicable platform fee. Selling contracts for \$25 before fees returns \$24.50 minus any applicable platform fee. These examples exclude separate swap and network costs. ## How does the Arcade fee work? Arcade rounds do not use contracts or an order book: everyone bets into a shared pool, and the winning side splits it. The fee is 1% of your payout, and your payout includes your own stake back: Payout = your stake ÷ the winning side's pool × the total pool × 0.99 For example, \$1 on Down against \$1,000 on Up pays about \$990 if Down wins. Losing bets pay no fee because they receive no payout, and stakes refunded from one-sided rounds or flat closes are returned in full with no fee. See [Arcade](https://docs.jup.ag/user-docs/trade/predict/arcade.md#how-is-my-payout-calculated). ## Can other routes add fees? Markets that use other routes can include additional or different fees: | Fee type | What it covers | | - | - | | Route fee | Fees from swap or liquidity routes used by a specific market | | Solana network cost | Transaction fees and account rent paid in SOL | Degen markets may use a different route from standard Browse markets, so the Polymarket fee rules above do not necessarily apply to them. Check the quote for the specific market and route before you sign. ## What Solana network costs apply? Jupiter Predict runs on Solana, so you need a small SOL balance for: * Transaction fees, paid when you sign transactions. * Account rent, a temporary deposit some on-chain accounts require. Rent is recovered automatically when eligible accounts are closed. These are standard Solana network costs, separate from Predict trading fees.
