Arcade: one-minute Up or Down rounds on Jupiter Predict

The Arcade, in its own tab of the Predict navigation (jup.ag/prediction/arcade), runs continuous one-minute BTC and SOL Up or Down rounds. It is a parimutuel game: instead of trading contracts against an order book, everyone bets into a shared prize pool and the winning side splits it.

​

How does an Arcade round work?

Rounds run as a continuous carousel of cards: Ended, Live, Next, and Later. You always bet on the Next round.

1. Pick a side: bet Up or Down on the round that starts next, in USDC. Entries are final.
2. Price locks: when the round starts, its opening price becomes the price to beat. A countdown shows when entry closes, and once the round is live no more bets are accepted on it. The live card reads Round is live, with a link to enter the next round.
3. The round runs 60 seconds: if the closing price is above the price to beat, Up wins. If it is below, Down wins.
4. Winners split the pool: each winner is paid in proportion to their stake, minus a 1% fee.

Each side shows a live payout multiplier (for example Pays 1.95x) computed from the current pool split. It moves as bets come in, until the round starts. Settlement is automatic and takes a few seconds: payouts and refunds are sent straight to your wallet, and there is nothing to claim. You can bet both sides of the same round; the round still settles normally.

​

How is my payout calculated?

Payout = your stake ÷ the winning side’s pool × the total pool × 0.99 The 0.99 is the 1% fee, taken from the whole payout, which includes your own stake back. For example, $1 on Down against $1,000 on Up pays about $990 if Down wins. Because the multiplier depends on the final pool split, the payout shown while you bet is an estimate. See Fees.

​

When is a round refunded?

A round is voided, and every stake is refunded in full with no fee, when:

• Only one side has entries.
• The closing price equals the opening price (a flat close).

​

How do I place a bet?

1. Choose BTC or SOL at the top of the Arcade.
2. On the Next round card, enter an amount in USDC or pick a shortcut (5, 25, 100, or 500 USDC).
3. Click Enter Up or Enter Down and sign in your wallet.

A bet goes through Preparing Bet, a signature request in your wallet, and Placing Bet. On success, the Bet placed toast links to the transaction; on failure, the toast explains the error.

​

How does Quick bet work?

Quick bet, at the top right of the Arcade, places a bet in one tap. Turn on its toggle and set the amount (5, 25, 100, or 500 USDC, or a custom amount): a tap on Up or Down then places that amount with no confirm step. Arcade Quick bet is separate from the Quick Buy setting used on Browse and Degen markets.

​

What happens after I win?

After a winning round, a prompt shows your side and the amount paid to you. Bet $… on Up again (or Down) places your whole payout on the same side of the next round; Keep it closes the prompt.

​

How does Auto-bet work?

Auto-bet, next to Quick bet at the top of the Arcade, places a series of bets for you. Choose the asset (BTC or SOL), the direction (Up or Down), the USDC per bet (5, 25, 100, or 500 USDC, or a custom amount within the per-entry limits), and the number of bets, from 5 to 30. The total cost, the amount per bet multiplied by the number of bets, is taken from your wallet when you sign, and the run starts once that funding confirms. It then enters each eligible minute round on your side until the bets are used up; settled rounds pay out like manual bets. You can run one Auto-bet per asset, so a BTC run and a SOL run can go at the same time. The Auto-bet chip shows the progress of a running run (for example 3/10), and each run has a card with its direction, stake, bets placed, and remaining budget, plus a Stop button: stopping refunds the USDC not yet bet. In your history, the Individual and Auto-bet tabs separate manual bets from runs, and a run expands to show each of its rounds with its result and payout. Arcade bets, manual or automatic, do not count towards clan volume and PnL.

​

Where can I see my results?

With your wallet connected, the Arcade page shows:

• Your last five results, with any streak, next to the asset picker.
• Your stats: record, rounds played, refunded rounds, and realized PnL.
• Your history: a preview of your last five rounds, which opens the full History page. It lists every past round with its asset, your entries, the outcome, the payout, your realized PnL, and explorer links to the settlement transactions.
• Live bets: a feed of everyone’s bets as they come in.

The Chart toggle shows a live price chart with the price to beat, and the sound toggle turns the countdown and settlement effects on or off.

​

How do I identify a round for support?

Arcade rounds have no event page or event URL. Each round is its own on-chain account, shown in two places: the round time on a round card (for example 11:01) is a link to the round’s account on the explorer, and the History page lists each past round with its shortened address (first and last four characters) as an explorer link, next to the date and time. When you contact support about an Arcade bet, give this round address or the explorer link together with your wallet address. The settlement transaction links in History help too.

​

Why is my Arcade bet blocked?

Each entry must stay between a minimum and a maximum amount in USDC, currently 1 USDC and 1,000 USDC per entry; the app shows the limits that apply. The bet button tells you what is wrong:

• Below minimum … USDC or Above maximum … USDC: your amount is outside the range.
• Insufficient USDC: your balance does not cover the bet.
• Couldn’t load limits: the configuration did not load. Reload the page.

Quick bet shows the same messages under the amount. The Up and Down buttons are also disabled once the countdown reaches zero and the round locks, and while a previous bet is still being sent. Trading is unavailable in some regions.
