Resolution criteria

This market will resolve to YES if the Season 4 premiere of House of the Dragon receives fewer than 20.0 million viewers during its initial premiere period. If the premiere receives 20.0 million viewers or more, the market will resolve to NO.

The resolution will be determined using official viewership data released by Warner Bros. Discovery (WBD) and reported by major industry trade publications such as Variety or Deadline.

• Primary Metric: The comparison will rely on the multi-platform (linear cable and Max streaming) viewership total captured over the first three days of availability (commonly referred to as the 3-day or L+3 multi-platform total).

• Reporting Shift: If WBD alters its primary reporting standard (for instance, releasing only premiere-night or 7-day multi-platform figures instead of a 3-day window), the market will resolve based on the primary debut metric reported by the aforementioned trade outlets.

• Data Unavailability: If no official multi-platform viewership figures are reported within 30 days of the premiere airing, the market creator may resolve the market using credible third-party industry metrics (such as Nielsen or Luminate) or resolve the market as N/A if no reliable data is available.
