When a case goes immediately to the US Supreme Court what kind of jurisdiction is invoked?

Answer 1

If the US Supreme Court is the first to hear a case, they are exercising original jurisdiction; if the Court hears a case directly from US District Court under appellate jurisdiction, bypassing the intermediate US Court of Appeals Circuit Court, they are exercising expedited jurisdiction (as well as appellate jurisdiction).

Answer 2

When a case goes immediately to the US Supreme Court, the jurisdiction invoked is the Court's original jurisdiction. This means that the case is being brought directly to the Supreme Court without going through lower courts. Generally, the Supreme Court exercises its original jurisdiction in cases involving disputes between states, certain cases involving foreign ambassadors, and cases where a state is a party and the Court has granted permission to hear the case.
