This market will resolve to "Yes" if conclusive proof that the earth is flat becomes public by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The resolution source for this market will be a consensus of credible reporting.Scientific consensus from centuries of astronomical observations, satellite imagery, and space missions establishes Earth as an oblate spheroid, driving the 99.4% market-implied probability for "No" on flat-Earth claims. Traders betting real capital recognize this as settled fact, with no meaningful recent developments or cultural shifts challenging the evidence. Historical patterns show flat-Earth ideas remain fringe without traction in mainstream discourse or media. Realistic upset scenarios are virtually nonexistent, as any reversal would require overturning physics and global exploration records—an outcome with no credible pathway in the foreseeable future.
