Traders have pushed the "No" outcome to a 97.5% implied probability because overwhelming scientific consensus, satellite imagery, and centuries of navigational data have established Earth's spherical shape as settled fact. Recent high-resolution space imagery and physics experiments continue to reinforce this view, leaving little room for alternative narratives in the market. While flat-Earth themes occasionally surface in online pop culture discussions or viral clips, they generate minimal traction among bettors who prioritize verifiable evidence. Realistic upset scenarios would require dramatic new findings contradicting established observations, an outcome traders consider highly improbable given the stability of current data.
