Overwhelming scientific consensus from centuries of astronomical observations, satellite imagery, and physics experiments continues to anchor trader sentiment at 99.1% for "No" on whether Earth is flat. This near-certain market-implied odds reflect the complete absence of credible empirical challenges in recent months, with flat-Earth narratives remaining confined to fringe online communities and entertainment-style memes rather than gaining any mainstream cultural traction or institutional support. Historical precedents of round-Earth confirmation through navigation, gravity models, and space missions further reinforce the consensus. Realistic upset scenarios would require an unprecedented, verifiable global revelation contradicting all established data—an outcome traders correctly view as extraordinarily unlikely given the stability of current evidence and lack of emerging catalysts.
