The disproportionate number of American firms in the ranks of international titans now can result from a confluence of favorable factors in recent decades.  But such dominance also holds a disconcerting lesson, going by events within the last 3 decades.

Ultimately,  U.S. mega-caps trade at multiples that have expanded substantially over the last five decades, and also at premium valuations compared to their international competitors.  That usually means that a dollar of net income will probably bring a higher market value for a U.S. mega-cap, in comparison to a European or Asian company.

As of Nov. 6, 73 companies worldwide had a market capitalization of $100 billion, making them "mega-caps."  Of these, 44, or 60% of the total, are U.S. companies, while Europe accounted for 16 companies, or 22 percent of the total.  China/Hong Kong donated 10 companies, or 14 percent, while Japan, Korea and Taiwan had one each.
