The combined market value of the United States' Magnificent Seven tech giants has now exceeded the entire output of the European Union, as a relentless rally in technology stocks stretches valuations and stokes concerns over potential market excess.
As of the close on 2 October 2025, the seven leading US tech companies — Nvidia, Microsoft, Apple, Alphabet, Amazon, Meta and Tesla — commanded a total market capitalisation of $20.8 trillion (€17.7tn), eclipsing the EU’s total economic output of $19.4tn (€16.5tn).
