Does apple card show up on credit Karma??

I can tell you only from my personal experience. Yes, my Apple Card is listed on my Credit Karma account by TransUnion but not Equifax. I believe Goldman Sachs uses TransUnion to determine credit worthiness.

I have no idea. I applied for the card almost immediately after it was introduced. At the time the question arose as to whether Goldman Sachs was going to send credit data to the various credit reporting agencies like TransUnion, Equifax, and Experian. They started doing so sometime later. Why do you ask?

You would need to call credit Karma and Goldman Sachs to find out if they have that information.
