Trader consensus shows a near-certain 99.3% implied probability against a flat Earth, driven by centuries of verified scientific evidence from satellite data, gravitational studies, and global navigation systems. No recent developments or cultural shifts have introduced credible challenges, leaving fringe online narratives without measurable momentum or mainstream traction. Historical voting patterns in public understanding favor the spherical model overwhelmingly, similar to how precursor awards lock in frontrunners. Realistic upset scenarios remain remote, requiring unprecedented new evidence contradicting established physics—an outcome traders see as negligible given the absence of any timeline or catalyst that could alter the outcome.
