If there is a joint effort between two organisations (eg spaceX and NASA) I'll resolve to the one that paid for the trip. 

For example a spaceX rocket landing on the moon, paid for by the Artemis program, would resolve to NASA (if this market were about the moon. 

If an organisation sells tickets, it's the organisation paying for the trip and not the people/organisation buying the tickets. 

If they share the cost I'll resolve to the share of the cost the organisations pay.
