Prediction Market Arbitrage Tools: Kalshi, Polymarket, and Cross-Venue Execution
Ryan BajollariExplore prediction market arbitrage tools for Kalshi, Polymarket, and cross-venue execution, including backtesting, fees, fills, and risk controls.
Prediction market arbitrage tools look for price differences across related event markets, but a visible spread is not the same thing as a locked-in result. Fees, fills, timing, liquidity, and settlement rules can turn an apparent edge into a loss.
This is not financial advice. Prediction markets carry risk, and cross-venue automation adds execution risk.
Prediction market arbitrage tools: what they need to do
A serious arbitrage workflow should include:
- Event matching across venues.
- Fee and spread modeling.
- Conservative fill assumptions.
- Failed-leg handling.
- Capital allocation across venues.
- Monitoring and pause controls.
TurbineFi’s Kalshi Polymarket arbitrage bot workflow is designed around research, backtesting, and controlled automation rather than treating arbitrage as free money.
Kalshi and Polymarket cross-venue risks
The hardest part is not detecting a price gap. It is executing both sides at the expected prices and understanding whether the contracts truly resolve the same way. A cross-platform arbitrage bot should assume missed fills, stale prices, and capital constraints will happen.
That is why backtesting and stress testing matter before live execution.
