How it works
One dashboard.
Two platforms.
Zero guesswork.
We fetch everything
Every 2 minutes, we pull all active markets from both Kalshi and Polymarket, normalise the data, and store a full price history. You never need to check two sites again.
You see both prices
For every market that exists on both platforms, we show you the prices side by side. When they diverge, we flag it. When the spread exceeds 2pp, we highlight it as a potential arbitrage opportunity.
You trade smarter
Click any Trade button and go directly to the better-priced market on the relevant platform. Always get the best price. Never leave money on the table from platform differences.
