Cross-Platform Spread Visualizer

Events where platforms disagree most on the same outcome. Wider spreads mean a larger gap (in percentage points) between the highest and lowest implied probabilities — strong signal to dig into the why: proprietary info, stale line, or simply inefficient market.

How to read these spreads

• ≥ 5 pp : interesting signal — worth a look
• ≥ 10 pp : possible significant mispricing
• ≥ 15 pp : likely, but verify (stale line or timing mismatch)
• ≥ 25 pp : suspicious — outcomes mismatched or data corruption (our h2h cap filter excludes them above 50 pp)
