Trader consensus reflects the overwhelming scientific evidence—from centuries of astronomical observations, satellite data, and physics principles—that has long established Earth's spherical shape in both academic and popular understanding. Fringe flat Earth narratives persist as cultural memes in online communities and occasional entertainment content but lack any credible momentum or recent developments to challenge the established consensus. With probabilities this lopsided, the market captures broad agreement backed by verifiable records and historical precedent. Realistic upset scenarios would require an unprecedented global revelation or paradigm-shifting discovery that upends core physics, a threshold far beyond current trajectories.
