Resolution criteria

This market will resolve to YES if the peak concurrent (simultaneous) viewership of NASA's live broadcast of the August 12, 2026 total solar eclipse exceeds 2,000,000. Otherwise, this market will resolve to NO.

The outcome will be verified using the following priority of sources:

1. Primary Source: Official post-event articles, metrics summaries, or press releases published by NASA on nasa.gov detailing the official aggregate peak concurrent viewership across its streaming platforms (NASA+, NASA App, NASA.gov, and social media channels).

2. Secondary Source: If NASA does not publish an official aggregate peak concurrent viewership figure by November 12, 2026, the market will resolve based on the peak concurrent viewer count on NASA's primary official YouTube channel (@NASA) livestream of the eclipse. This peak will be verified using reputable third-party livestream database trackers (e.g., Streams Charts, Playboard) or archived screenshots/records of the live stream's peak viewer count.

Note: If NASA does not host a live broadcast of the August 12, 2026 eclipse, this market will resolve to NO.

Background

On Wednesday, August 12, 2026, a total solar eclipse will sweep across Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain, and Portugal. NASA has announced that it will host a live broadcast of the event starting at 1:15 p.m. EDT on August 12, featuring views from Iceland and Spain.

Viewership benchmarks for prior eclipses:

• 2024 Total Solar Eclipse (North America): NASA reported that at its peak, 1,458,212 people watched the eclipse broadcast live across its digital platforms (NASA+, the NASA App, NASA.gov, and NASA social media channels).

• 2017 Total Solar Eclipse (North America): NASA reported a peak of between 2 million and 3 million simultaneous views on its Eclipse Live page.

Because the 2026 path of totality lies largely outside of the continental United States, interest and viewership patterns may differ from the 2017 and 2024 events.
