Trader consensus on Polymarket has locked in April 11 at 100% implied probability for the first eaglet hatch at the viral Great Lakes Bald Eagle Cam nest in Traverse City, Michigan, where parents Harry and Harriet have incubated three eggs laid March 2, 5, and 8. Live stream viewers witnessed decisive hatching signs today, including the mother eagle relocating large shell fragments around 2:11 ET, signaling the chick's full emergence after a protracted 39-day wait for the lead egg—aligning with bald eagle norms amid cool Michigan weather delays. This skin-in-the-game verdict reflects aggregated public fervor from the 24/7 nest cam's massive audience. Realistic upsets hinge on strict resolution rules demanding unambiguous visibility of complete hatch; murky footage could prompt oracle review, pushing to April 12 or "No Hatch before April 17" if disputed. Market now in review as eaglet care begins.
