Trader consensus on Earth's shape reflects the overwhelming weight of established scientific evidence, from satellite data and gravitational physics to centuries of navigation and space exploration that have long defined public understanding. Occasional viral spikes in flat Earth content across social media and entertainment keep the topic alive as a cultural meme, yet these have produced no meaningful momentum shift in the market.
