Sell SPACEX by Dec 25, 2026.

I am greatly exposed to sp500. After watching https://youtu.be/T-oXyXwD6sE?si=78B69OKPqCSHaRim, I can’t believe spacex valuation. I’m worried about my exposure to AI, since I have most of my money in sp500. Is shorting spacex a good hedge? It looks like, if AI is a bust, the short will work, and if AI is a money making machine, nvidia and other companies will grow more than spacex.
