What is the difference between an event and a market?
An event is a real-world occurrence with a determinable outcome, for example “Republican Presidential Nominee 2028” or “UEFA Champions League Winner”. Each event contains one or more markets. Each market represents one possible outcome within the event and is usually binary: YES or NO. An election event can hold a separate market for each candidate, and each market trades independently. See How do multi-outcome events work?What states does a market go through?
- Upcoming: the market is visible but trading has not started. The UI may show a countdown.
- Open (Live): the market is trading. Buy and sell actions are available when liquidity and routing support them. Live timed markets show a compact countdown on their card, with an urgency state in the final 30 seconds.
- Closed: trading has stopped. The market is waiting for its result to be determined and recorded.
- Settled: the result is final. Your profile shows a claim, refund, automatic, lost, or final status. See Settlement and payouts.
What is a contract?
A contract is a claim on one side of one market.- A winning contract pays $1 worth of the market’s settlement asset.
- A losing contract pays $0 and expires worthless.
- Some markets can resolve to a refund or a draw when their rules require it.
How do I read a contract price?
Contract prices usually range from $0.01 to $0.99 and reflect the market-implied probability of that side. A YES contract at $0.65 means traders are currently paying about 65 cents for the YES side. Prices are set by supply and demand: they move with liquidity and new information, and they are not guaranteed probabilities. The settings menu (the sort icon) on Browse, event, and Degen pages switches the display between cents, the default, and a decimal odds-style multiplier (55¢ or 1.82x). The choice is saved in your browser. Spread warnings are always expressed in cents, and charts keep the cents format.Which token do I pay with?
Predict uses dollar-pegged assets for trading and settlement. The exact funding token can depend on the market and route, and in some flows Jupiter routes your input into the market’s settlement asset before the order is placed. The order form shows the token you pay with and, once you enter an amount, the quote: size, number of contracts, expected payout, and any estimated refund. Trading fees are included in these amounts rather than shown as a separate line. See Fees.What is the spread?
Each market has a bid price and an ask price:- The ask is what you pay when buying.
- The bid is what you receive when selling.
Which order types can I use?
Market orders
Market orders are the main order type on Predict. A market order executes at the best available price for the selected side.- The quote is based on the current price and liquidity.
- If the price or liquidity changes too much before execution, the order fails or partially fills rather than executing at a much worse price.
- If less than the full amount executes, unused funds are returned automatically.
- Fees are charged only on the executed portion.
Limit orders
Limit orders let you set a target price and wait for a match. Switch the order form to the Limit tab and enter your price.- Available on Polymarket-sourced markets only, and only as limit buys. Limit sells are disabled.
- Open limit orders are listed in the Open Orders tab of your profile, and you can cancel them before they are matched.
- Jupiter Forecast markets and sports ticket markets are market-order only. A Limit tab may still appear on the order form there, but it is disabled.
What happens when I place an order?
In normal use, you only sign the transaction shown in your wallet.1
Quote
The app checks the selected market’s route and estimates the price, contracts, fees, and payout.
2
Sign
You review the quote and sign the transaction in your wallet.
3
Execute
Jupiter validates the trade and executes it through the market’s route or integration.
4
Update position
If the trade executes, your position appears in your profile. If it cannot execute, or only partially executes, unused funds are returned automatically.
How does Quick Buy work?
Quick Buy buys in one tap, skipping the order form. Open the Quick Buy control (the lightning icon with an amount, on Browse and Degen), turn on Quick buy, and set the amount and the token to pay with: USDC, SOL, or JupUSD. Quick Buy is off by default, and the settings are saved in your browser. With Quick Buy on, a Yes, No, Up, or Down button and Copy bet place an order for that amount right away, after your wallet signature. A toast follows the order until the position opens. The Arcade has its own one-tap setting, Quick bet.What are the order limits?
Limits depend on the market type. The order form shows the limits that apply; the values below are the current ones, and the app prevails.Where do the markets come from?
Jupiter Predict surfaces markets from external prediction market providers and Jupiter-supported market integrations. Browse markets are currently sourced from Polymarket, alongside short-duration crypto markets and other Jupiter-supported integrations.- Not every market from every source is available on Jupiter.
- Some markets can be view-only, closed, unavailable in your region, or temporarily unavailable for buys or sells.
- Each market follows its own published rules. Read the rules summary on the event page before trading.
- Some market routes record eligible results on-chain; other integrations settle through their own process and reflect the status in your profile. See Settlement and payouts.
- Predict has no market creation flow: new markets come from the providers and integrations, not from Jupiter.
