Opening-weekend markets
These ask whether a film's reported earnings over its first weekend pass a stated level. The rules say exactly which days count, for example Friday to Sunday, and how holiday weekends are handled.
Total-gross markets
These ask about a film's earnings up to a set date. Check whether the figure is for the US and Canada only or worldwide, and which report counts if numbers are revised later.
Read the settlement source
Every box office contract names its data source and the time it's read. Two markets on the same film can use different windows, so read each one.
