Resolution criteria

This market resolves to YES if, at any point between January 1, 2026, and December 31, 2026, inclusive, a team of researchers or explorers publicly announces that they have successfully entered, deployed exploratory equipment into, or physically accessed the space known as the "Big Void" within the Great Pyramid of Giza.

Access is defined as either human entry or the successful insertion of a probe, camera, or sensor package into the interior of the void, substantiated by credible media reporting or official statements from Egypt's Ministry of Tourism and Antiquities (https://mota.gov.eg/en/).

If no such access is confirmed by public record or official announcement by the end of 2026, the market resolves to NO.

Background

The "Big Void" is a large, previously unknown interior space within the Great Pyramid of Giza, first identified in 2017 by the ScanPyramids project using muon radiography—a technique that detects density variations within large structures. The void is located above the Grand Gallery and is estimated to be at least 30 meters long, though its exact purpose, contents, and connectivity to other known chambers remain subjects of intense academic debate and archaeological mystery. To date, the void has not been directly accessed by humans or robotic probes.
