That’s interesting(?), given that Musk illegally failed to disclose when his holding exceeded 5%, which the SEC (and the other shareholders now suing him) reckon saved him something like $150million, because he would have had to pay a lot more for his 9.2% if people had known he was trying to acquire it.
So if someone else was buying up shares at the same time, you might idly speculate whether they had access to the same secret info.
