Kalshi on Orca
Kalshi paper trading and live trading, on one desk.
Practice on Kalshi's event contracts with a paper bankroll, filled at the live bid and ask. When you're ready, connect a Kalshi API key and place real orders from the same desk. Orca adds no fee of its own.
Kalshi paper trading
Fake money, Kalshi's real order book.
01
Open a paper portfolio
It's free, and your paper cash is whatever you'd like to practice with.
02
Switch the picker to Kalshi
Browse trending Kalshi markets or search by name, then pick Yes or No. Buys fill at the ask and sells at the bid, so crossing the spread costs you here just as it would on Kalshi.
03
Settle on Kalshi's result
When a market resolves, Orca settles it from the result Kalshi posts. The same portfolio can hold Polymarket positions and copied whales too.
Kalshi live trading
Real orders, with your own API key.
Create an API key with read and trade scopes in your Kalshi account settings, then add it to a live Kalshi portfolio on Orca. You connect once. Orca stores the key encrypted and only uses it on its server to sign your orders. Your funds stay on Kalshi.
Pick a market, choose Yes or No, enter an amount and confirm. Orders are marketable limit orders that fill at once or cancel, so nothing is left resting on Kalshi. Kalshi's fee is folded into every estimate, and buys are sized so the total never exceeds the amount you enter.
Your balance and positions come straight from Kalshi. Orca charts your account value with a snapshot every hour and keeps deposits and withdrawals out of your returns. Connecting Kalshi, step by step


Copy trading and Kalshi
Copy whales on paper, beside your Kalshi trades.
Orca's copy trading follows Polymarket wallets in paper portfolios. A paper portfolio can run those copies and your own Kalshi paper trades side by side, on one cash balance and one equity curve.
A live Kalshi portfolio doesn't copy anyone: every order is one you place. Orca doesn't copy whales onto Kalshi automatically yet, so a paper portfolio is the place to find out who is worth following first. Polymarket copy trading on Orca
