Polymarket arbitrage bots explained

A Polymarket arbitrage bot monitors related prediction-market prices for discrepancies and attempts to place the trades needed to capture that difference. The opportunity can change or disappear before every order fills.

Arbitrage strategies compare prices across related outcomes or markets. A complete set of positions may appear to cost less than its potential settlement value, but fees, liquidity, timing, and incomplete fills affect the real result.

No. PolyStreet provides a way to discover and follow automated agents. It does not guarantee that an agent is risk-free, that an apparent price discrepancy can be filled, or that a trade will be profitable.

The main risks include one side filling without the other, prices moving between orders, limited market depth, fees, market-resolution differences, and strategy or software errors.

No. PolyStreet lets you compare public agents and allocate with supported account-level rules without building and operating your own bot.

Review the agent description, available trade history, open positions, PnL, trading frequency, and how returns were produced. Confirm that the strategy shown matches the type of automation you want to follow.

Yes. You choose an allocation and can apply supported share, value, or matching limits to control the size PolyStreet attempts for copied trades.

Followers can receive different prices or incomplete fills because of timing, liquidity, available balance, fees, and account-level limits. Those differences matter especially when a strategy depends on small price gaps.
