Predictions
Trade on the outcome of real-world events through Polymarket.
How prediction markets work
Each market asks a question with a clear resolution rule, such as "Will X happen by date Y?". You buy shares in an outcome. Every share of the winning outcome pays $1.00 when the market resolves; shares of losing outcomes pay nothing.
The price of a share, from 1¢ to 99¢, is the market's implied probability. Buying "Yes" at 35¢ means the market prices the event at about 35%. If you are right, each share you bought for 35¢ pays $1.00.
Kyro Zeta connects directly to Polymarket's order book. Orders are matched and settled by Polymarket on Polygon, and markets resolve according to Polymarket's rules and resolution sources. Kyro Zeta does not create, operate or resolve markets.
Your predictions account
- Polymarket trades from a Deposit Wallet: a wallet on Polygon that only your key controls. A Kyro Zeta wallet or email login already has the key; with a Solana-only wallet such as Phantom, connect MetaMask, Rabby or another EVM wallet too.
- Start trading predictions sets everything up in one step: it opens your Deposit Wallet and lets Polymarket's exchanges settle your trades. It is free and happens once; there is no POL or gas to pay.
- Markets settle in pUSD (Polymarket USD, backed by USDC). Add pUSD bridges SOL or USDC from Solana, or ETH, USDC and other tokens from any of Kyro Zeta's EVM chains, straight into your predictions balance.
- Each order is a signature from your wallet and costs no network fee.
Finding markets
- Browse by category and sort by trending, total volume, newest, ending soon or liquidity.
- Search by keyword, such as an election, an asset or a central bank decision.

Market orders
A market order fills now against the live order book, never past the price shown. If the book isn't deep enough for the full size, only what fills at that price goes through and the rest is cancelled. Some markets carry a Polymarket taker fee; Kyro Zeta adds none.
Minimums
Each market has a minimum order size in shares, shown in the panel when your order is too small.
Positions & payouts
My positions lists every open position with its value and unrealized PnL. You can sell shares at any time before resolution, and cancel open limit orders there. After a market resolves, select Claim next to a winning position to receive $1.00 in pUSD for each winning share; claims are free. Withdraw sends your pUSD balance to your own address on Polygon, and Bridge moves it on to Solana or any other chain.
