Why cross-venue comparison matters

Same market, different prices

Polymarket, Kalshi, and Limitless often price the same outcome differently — sometimes by 3–8 percentage points. Mantis finds the gap automatically.

Best line, not just any line

Every market card links to the highest-liquidity venue first so you can execute on the tightest spread, not just the venue you happen to use.
