The timing of this just before pride month is not a coincidence.

This market resolves YES if such an attack is attempted in June 2024, regardless of its outcome (e.g. a terrorist cell being arrested while planninng an attack would count, as long as the details are made public by the corresponding law enforcement agency or widely disseminated in the news).
