Why cross-platform comparison matters
Different prediction markets price the same events differently. A contract at 58¢ on one platform might trade at 52¢ on another — a 6-point implied probability gap on the same underlying event. These discrepancies create positive expected value (+EV) opportunities.
Understanding each platform's strengths, weaknesses, fee structures, and liquidity profiles helps you decide where to trade and how to size positions. EVSignals scans all major platforms simultaneously to surface these cross-platform edges automatically.
