For the first time in history, a company has exceeded $4 trillion in market capitalization. That company is, of course, Nvidia. It crossed this threshold on July 9 and has been breaking records ever since. At yesterday's close, Nvidia was worth $4.18 trillion.

Apple and Tesla combined

And while Apple has long held the position of world's largest market capitalization, the iPhone maker's market cap is now "only" $3.1 trillion. Even when Tesla's market cap (approximately $1 trillion) is added, it is still below Nvidia's.

Beyond the battle over who is biggest, it is important to measure how significant Nvidia's size is in terms of global markets. This single stock now accounts for 3% of total market capitalization.

Another calculation by MarketScreener's macro research teams is also quite representative. Nvidia's market capitalization is higher than that of all CAC 40 companies combined with 36 DAX companies (all but the four largest DAX stocks).

Markets are becoming increasingly concentrated

However, this is nothing new. For many years now, large tech stocks have been gaining more and more weight in the indices. This is known as concentration and can also be explained by the fact that these few stocks – the so-called Magnificent Seven – also account for the lion's share of profits.

Is this situation healthy? No. But is it unjustified? No, not when you consider the profitability of these companies and their ability to consistently outperform the rest of the pack.
