Scanner coverage
Every open Kalshi and Polymarket event, checked in rolling sweeps. Spreads already in the feed are re-priced about once a minute.
Opportunities
Bundles that pay a fixed amount whichever outcome wins, priced at the best ask and the size resting there, after each platform’s fees.
| Event | Cost / bundle | Pays | Net / bundle | Return | Size | Profit at size | Closes |
|---|
Prices can change or disappear before you act, and every leg is a separate order — if one doesn’t fill you’re holding the others unhedged. Capital stays tied up until the event resolves. Fees shown use Kalshi’s published fee schedule and each Polymarket market’s own fee settings; your actual fills may differ. ArbTrader never trades on its own. Not financial advice.
