Type II NPD. Musk has covert narcissism. His recent passive-aggressive posts regarding Starlink and Ukraine, plus blaming activists for advertisers leaving Twitter, gives it away. Passive-aggressiveness and blaming are particularly common to Type II. Seeing those, we wouldn't need to look too hard for other Type II NPD symptoms, such public generosity along with being cruel in private, being intolerant of or oversensitive to criticism, smugness, self-absorbtion, self-criticsm, shyness, perfectionism, holding grudges, and all types have strong denial and low empathy. Though if Musk often engages in humiliating others, I have it wrong; that's Type III, toxic. Usually successful individuals will get NPD buttoned up along with becoming fit even though denial is very difficult to overcome.

What would make you think he was bipolar? There are other symptoms, but BPD requires depressions and manias.
