Polymarket Kalshi arbitrage bot for related event markets

A Polymarket Kalshi arbitrage bot is not a second copy of the Polymarket trading bot. It exists because the same political, macro or crypto event often trades on both venues with different fees, hours, contract specs and settlement rules. This package watches mapped pairs, compares implied odds and only treats a gap as a candidate after costs.

How the cross-venue edge is calculated

Each cycle pulls Polymarket CLOB prices and Kalshi contract prices for a mapped event, normalizes them to implied probability, subtracts taker/maker fees, estimated slippage and a latency buffer, then checks inventory on both sides. If one leg cannot be sized, the route is dropped. Gross odds gaps without a hedge plan are ignored.

Execution, alerts and risk limits

You can run alert-only, one-leg-then-confirm, or paired execution with hard caps. Kalshi and Polymarket do not share a wallet, so capital has to sit on both venues. The bot does not move fiat between them. Settlement mismatch, halt risk and resolution-rule differences are operator problems; the software can only refuse a route that fails the configured filters.

PRODUCT FAQ

Questions about this bot.

What does a Polymarket Kalshi arbitrage bot actually compare?

It maps related event contracts on Polymarket and Kalshi, converts both books into implied probability, subtracts fees and estimated slippage, then flags a route only when the net edge clears your threshold.

Can it trade both venues automatically?

Yes, if you supply API credentials and enable execution. The default recommendation is alert-plus-manual confirmation until both legs, settlement rules and withdrawal limits are tested with small size.

Is this the same as the Polymarket Bot?

No. The Polymarket Bot focuses on Polymarket-native YES/NO, momentum and copy-trade workflows. This SKU is the cross-venue Polymarket Kalshi arbitrage bot.

BEFORE DEPLOYMENT

Validate the operating boundary.

Start with isolated infrastructure, low-permission credentials and a controlled balance. Review every venue adapter before enabling automated execution.

01

Test with current market data

Run simulations against live fees, gas and liquidity instead of relying on historical screenshots.

02

Limit credentials and capital

Use dedicated wallets and withdrawal-disabled exchange keys wherever the venue supports them.

03

Monitor every decision

Retain route estimates, configured limits, submitted transactions and final status for diagnosis.
