Billionaires' wealth declines $210 billion post-Trump inauguration

Tech billionaires who attended Donald Trump's inauguration have lost a combined $210 billion in wealth since January 20. This decline follows a period of market highs before the inauguration, marking a significant shift in their fortunes. The companies linked to these billionaires have seen a total market value drop of $1.43 trillion since January 17. Elon Musk experienced the largest loss, with a $145 billion decrease, while Jeff Bezos and Sergey Brin lost $31 billion and $23 billion, respectively. The S&P 500 Index has fallen nearly 7% since Trump took office, impacted by government layoffs and uncertainty over tariffs. This contrasts sharply with the gains seen in the weeks following the election.
