Traders have pushed the "No" outcome to a 97.3% implied probability because overwhelming scientific consensus from centuries of astronomical data, satellite imagery, and physics experiments leaves little room for doubt about Earth's spherical shape. This reflects aggregated sentiment backed by real capital, much like how cultural narratives around conspiracy memes gain viral traction yet rarely shift broader industry or public consensus. No recent verified developments have altered the established model, and fringe flat-Earth discussions continue mainly as online entertainment rather than serious challenges. Realistic upset scenarios would require extraordinary new evidence contradicting all known gravitational and observational records, an outcome historical patterns suggest remains highly improbable.
