Bitcoin spot ETF approval timing — when crowd consensus is right but priced wrong

Problem

Multiple Polymarket contracts on Bitcoin ETF milestones were priced between 55-65% YES, but the underlying probability structure showed much higher confidence when decomposed into conditional events.

Signal

EdgeVisor's base-rate analyst combined with news-sentiment scoring detected that regulatory signals were consistently more positive than the crowd price reflected. The favorite-longshot bias was pulling prices toward 50% on what was structurally a 75%+ event.

Result

The contracts resolved YES. Traders who entered at 60% captured 40% edge on resolution, with minimal drawdown as the price moved steadily upward.

Lesson

Crowd aggregation on regulatory events tends to under-correct for confirmation bias in negative scenarios. When 5+ independent signals align, the real probability is often 15-20 points higher than the market price.
