Frequently asked questions

A trading terminal for prediction markets. Every market, price and order book comes live from Polymarket, and you trade them with a single USD balance funded from Robinhood Chain or Solana.

A market on a yes/no question. A Yes share pays $1 if the event happens and $0 if it doesn’t, so a 62¢ price means the market thinks it is 62% likely.

No. Every visitor gets $10,000 in demo funds to practise with. Create a free account to deposit, trade live and keep your history across devices.

USDG or ETH on Robinhood Chain, or USDC, USDT or SOL on Solana, from MetaMask or Phantom. Everything is credited to one USD balance once the transfer is confirmed on-chain.

A 1% entry fee on your margin, plus 0.2% of margin for each 1× of leverage, plus a flat $0.50 network fee. The full breakdown is shown before you confirm.

Leverage (up to 10×) multiplies your exposure to price moves, in both directions. If the price moves far enough against you, the position is closed automatically so you can never lose more than the margin you put in.

Yes. Add them when you open a live position or later from your portfolio. They are checked automatically, even when you are offline.

Orders that wait for a better price. Your margin and fees are held until the order fills or you cancel it, and holds are released straight back to your balance on cancel.

Combine 2 to 8 markets into one slip. The odds multiply, every leg has to win, and live parlays pay out up to $5,000. The parlay fee rises with the payout multiple (Under 5×: 5% · 5–20×: 7.5% · 20–100×: 10% · 100× and up: 15%), charged on the stake.

Withdraw from $10 to a wallet you have linked and signed for. Every withdrawal needs a code from your authenticator app, and a newly linked wallet can receive withdrawals 24 hours after linking.

Withdrawals are reviewed and paid from the platform wallets. Live queue times are published on the Status page.

Only if you choose. Profiles are private by default; on leaderboards you appear as an anonymous “Trader #1234” unless you turn on a public profile in Settings.

Free reward boxes: one every day, plus welcome, milestone, quest and referral crates. They contain fee credit, fee discounts or collectible cards. Fee credit pays trading fees; it is never withdrawable cash.

Every live trade earns back a share of the fee you paid (5% at Bronze up to 25% at Diamond) plus 0.01% of the volume you trade, claimable as fee credit.

You earn 15% of the trading fees your direct referrals pay, then 5%, 2.5% and 1% across the next three levels of your network. Rewards come out of Probio’s share, not your friends’ trades.

Nine cards from Common to Legendary, pulled from crates. You can download the ones you own as high-res images to share. Duplicates turn into fee credit.

Directly from Polymarket’s public market data and order books. Probio does not create or move odds.

Each market page has a “Why is this moving?” panel that lines the sharpest recent swings up with news headlines published around the same time.

By the rules and source written in that market’s description, as resolved on Polymarket. Winning Yes or No shares settle at $1, losing ones at $0.
