Traders have pushed the "No" outcome to a 99.3% implied probability, driven by the entrenched scientific consensus from satellite imagery, gravitational data, and centuries of astronomical observations that leave no room for a flat model. No recent verified developments from space agencies or research institutions have introduced credible challenges, keeping the market aligned with established facts rather than fringe online narratives that occasionally surface as cultural memes. While flat-Earth discussions persist in niche communities, they hold no sway over institutional positions or empirical records. Realistic upset scenarios would require an unprecedented global revelation contradicting all existing evidence, an outcome with no current indicators or historical precedent.
