Here is the list:
There are no European or Chinese companies on the list. There is one Taiwanese company (TSMC), a Saudi company (Saudi Arabian Oil), and the rest are all American.
It's no surprise that there are no European companies on the list. Europe has been stagnating for over a decade. Even when there are good European businesses (LVMH, Rolls Royce), their shares remain undervalued, because European households prefer to keep their money in the bank rather than buy stocks.
More surprising is the lack of Chinese companies, given they are the world's second biggest economy. Most of China's manufacturering exports are brokered and matched with customers on Alibaba's excellent platform. But since the Chinese government moved to silence Jack Ma, investors have taken fright and Alibaba's share price has languished (it's down 43% over the last five years). Electric car companies like BYD are rising fast, but haven't attracted institutional investment.
There are only two companies from "traditional" sectors on the list; Eli Lilly (pharmaceuticals) and Saudi Arabian Oil. The rest are either semiconductors (Nvidia, Broadcom, TSMC) or tech. Given that Eli Lilly was founded in 1876, it's amazing that they are still in the global top tier.
How long the trillion dollar phase lasts is anyone's guess. When the AI bubble bursts (and all bubbles burst in the end), a lot of these companies will slip under the $1 trillion mark.
