In early July 2025, astronomers detected the third interstellar object ever recorded traversing our Solar System at high speed. Some researchers suggested it could be an extraterrestrial reconnaissance craft because 3I/ATLAS exhibits unusual characteristics. Calculations indicate it will make its closest approach to Earth in late November – early December 2025.

The market will resolve to YES if, by 23:59 UTC on December 15, 2025, it is officially confirmed that the object 3I/ATLAS is of artificial extraterrestrial origin.
