If we're really going to be pedantic, it won't get to the Supreme Court unless they grant a petition for a writ of certiorari or it's one of those rare, few types of cases where the US Constitution says the Supreme Court has original jurisdiction.

They do deny most such petitions, though, and resolving circuit splits is one reason they might grant cert.

Circuit splits are by far the most common way of getting cert. They don't grant cert to every circuit split, but most of what they do, however...

Indeed, and I should probably clarify one thing from what I wrote above: if the Supreme Court had original jurisdiction over a case, it would start with them, rather than being appealed to them. There aren't a lot of cases like that, though.
