Is Elon Musk Type AB?

 I found a site that states that Elon Musk is Type AB!

The information is from Wikipedia, but when I checked his blood type, it didn't say anything.

I also checked with Perplexity to be sure, but it also said his blood type was unknown.

Irritated, I checked on Bing (ChatGPT-4)...

Apparently, Wikipedia said he is Type AB.

I wonder which site is true?
