Scientific consensus and centuries of empirical evidence—from satellite imagery and GPS navigation to gravitational physics and circumnavigation records—anchor trader confidence that Earth is not flat, pushing the "No" outcome to a 99.3% implied probability. This near-certainty mirrors the decisive cultural rejection of flat-Earth claims in mainstream media and education, where viral social media challenges and occasional celebrity endorsements fail to gain traction against verifiable data. No meaningful recent developments have shifted the narrative. Realistic upset scenarios remain negligible, limited perhaps to an unforeseen global revelation or simulation disclosure that defies all current observations, though historical patterns suggest such twists stay firmly in speculative fiction territory.
