As of mid-morning Friday, Tesla market capitalization is up to $134 billion. The five giant tech company market caps are climbing back and now all higher than they were at the end of February. All five companies are global, but to put their massive valuation into perspective, it now represents 20% of the market cap of the U.S. S&P 500. Shareholders are happy but government regulators and politicians are gearing up for new regulations. The pressure on big tech will continue to mount.
