Summary
Since Trump’s second-term inauguration, five top billionaires have lost a combined $209 billion as markets react to policy uncertainty.
- 
Elon Musk’s net worth plunged $148 billion as Tesla shares collapsed amid declining European and Chinese sales. 
- 
Jeff Bezos lost $29 billion as Amazon stock fell 14%. 
- 
Sergey Brin’s fortune dropped $22 billion following Alphabet’s weak earnings and regulatory pressure. 
- 
Mark Zuckerberg and Bernard Arnault each lost $5 billion as Meta and LVMH stocks tumbled. 
The S&P 500 is down 6.4%, reversing gains seen post-election.


You seem to have forgotten to multiply by 100 after you divided 209 by 1,548.
209 is 13.5% of 1,548, not 0.13%.
Edit: It is a bit disturbing how many people upvote things without making even the most basic sanity check.
