Is Earth flat?

“Is Earth flat?” is a Culture prediction market asking whether conclusive proof that the Earth is flat will become public by December 31, 2026, 11:59 PM ET. The market resolves to “Yes” only if credible reporting establishes that proof; otherwise, it resolves to “No.” This makes the event a forecast about the appearance of definitive evidence, not a statement about current scientific consensus. As a conspiracy-themed event, it sits at the intersection of conspiracy theories, flat earth claims, and public information reporting, with the resolution source defined by a consensus of credible reporting. Market sentiment currently assigns a 2.6% probability to a Yes outcome, suggesting traders see the expected outcome as highly unlikely.
