Is Earth flat?
1 markets · 5mo
The market is virtually certain Earth is not flat, reflecting centuries of empirical evidence and modern space-based observation; the 2% chance for 'Yes' captures residual tail risk from fringe conspiracy theories rather than any plausible scientific debate.
What's driving it
- • Overwhelming scientific consensus and direct photographic evidence from satellites and the International Space Station have long settled the question, with no credible counter-evidence emerging (no clear catalyst recently).
- • The 98% No odds have been stable for years, indicating that no new information or event has challenged the established view.
- • Flat-Earth claims remain a niche online subculture without institutional support or empirical validation, limiting their ability to move mainstream probability.
The bullish case
- • A small but persistent community argues that all space agencies and governments are engaged in a global conspiracy to hide the 'true' flat geometry, citing alleged inconsistencies in horizon curvature and flight paths.
- • Proponents point to the lack of direct, independent verification of Earth's curvature by ordinary individuals without relying on official sources.
- • Some interpret the absence of visible curvature from typical ground-level perspectives as evidence that the Earth is flat, ignoring the scale required to observe it.
The bearish case
- • Direct photographic and video evidence from space, multiple independent space agencies, and commercial satellite operators consistently show a spherical Earth.
- • Practical applications such as global navigation systems (GPS), intercontinental flight routes, and satellite communications rely on a spherical model and would fail if Earth were flat.
- • Basic physics—gravity, Coriolis effect, and the behavior of shadows during lunar eclipses—are incompatible with a flat-Earth model and have been verified for centuries.
What to watch
- • A planned SpaceX Starship mission to orbit in late 2026 could provide additional high-definition live footage of Earth from space, likely reinforcing the No position.
- • Any major educational initiative or public statement from a respected scientific body (e.g., NASA, ESA) would further entrench the No consensus.
- • A high-profile flat-Earth advocate's experiment or claim that gains mainstream media attention could temporarily increase Yes odds, but would likely be debunked quickly.

Markets in this event
Is Earth flat?
The market reflects the near-total absence of any credible evidence for a flat Earth, with the 2% Yes representing only the theoretical possibility of a paradigm-shifting revelation before 2027.
Yes ≈ 2% chance
