Polymarket trading bots
Automate prediction markets
Prediction markets move on news, schedules and resolution rules, around the clock. Circuit agents trade Polymarket from a wallet you control: they find markets, buy and sell outcome shares, and redeem resolved positions without you watching every event.
What Polymarket agents can do
Agents search events or screen markets by how soon they end, price range, liquidity and sport, then quote and buy or sell outcome shares with Polymarket's fees included in the quote. They split collateral into both outcomes, merge them back, convert No shares across an event, and redeem every resolved market they hold. Circuit charges no builder fee.
Strategies agents run
Popular approaches buy outcomes that news or odds feeds make likely, fade overpriced longshots, buy complete sets when the asks sum below the payout, and pair a prediction with a related perp, such as buying YES on a launch and going long the matching stock the moment it resolves.
Test before you risk money
Every agent starts in paper trading: simulated funds on live markets, with no real money moving. Hyperliquid, Lighter and Kraken orders fill against the live order book and one-minute bars with each venue's fees, funding and liquidation rules, and Polymarket orders fill against the live book. Switch to real money when the results convince you.
Self-custodial by design
Agents run on a wallet you create in Circuit or import from Phantom, Rabby or MetaMask. Agents never see private keys: they request typed actions through Circuit's SDK, and Circuit signs outside the agent's sandbox only under a permit you sign with your passkey. Pause, resume or stop any agent at any time; stopping leaves your positions in your wallet.
Paper trade prediction markets first
In paper trading, Polymarket orders fill against the live order book and redemptions pay each market's real resolution, so you see how an agent would have traded an election, a sports season or a launch without risking money.
Funding and wallets
Polymarket trades settle in pUSD on Polygon. Circuit deploys a Polymarket Deposit Wallet for wallets it created, prepares any funding and wrapping as separate actions for you to review, and redeems resolved markets in one action that covers both outcomes.
How prediction market prices work
Each outcome share pays $1 if it happens and nothing if it does not, so a YES price of $0.62 implies the market sees a 62% chance. If you think the true chance is higher, buying YES has positive expected value; if lower, buying NO does. Agents automate that edge: they screen hundreds of markets for prices that disagree with a signal, such as polling, odds feeds or news, and size each bet by the gap.
Polymarket bot FAQ
Can agents trade sports markets? Yes, screening can filter by sport market type, and you can exclude sports entirely. What happens when a market resolves? The agent redeems it, which pays $1 per winning share and nothing for losing shares. Can I test first? Yes, paper trading fills against the live book and pays real resolutions.
What it costs
Circuit charges no fees today. You pay the venue's trading fees, network gas and any bridge or routing fees, and each prepared action's review shows the costs it reports before you confirm. Today's terms make no commitment about future fees.
Getting started
Sign in to app.circuit.org with a passkey, create a wallet or import an existing one, and fund it with crypto or a debit card. Open an agent, choose an allocation and start it in paper trading; when the results convince you, switch the same agent to real money. Pause, resume, top up or stop it any time from your home screen.
