>I'm going to guess that this part is intentional. Europe tends to be more aggressive in enforcing antitrust laws. Economically, Europe's goal isn't to have the biggest companies but to have more smaller companies.
So is your hypothesis that the total market cap of EU tech companies is something like 50,60,70, etc. % of total US tech marketcap? Something significantly different than the ~10% implied by that figure (largest us companies 10x largest EU companies). And it's just more broadly distributed?
European companies are smaller on average and less likely to go public in general, so market cap comparisons don’t show the whole picture. Growing big is less often seen as a goal than in the US. “Megacaps” aren’t necessarily considered a healthy thing to have.
I don't see any sense in which the EU has fewer capabilities. It has, say, a smaller number of businesses with smaller market dominance.
It isnt clear to me what capability the EU would gain by having a monopolist social network, a monopolist search engine, a monopolist advertising trader

Hard to find data on this but this is showing EU tech market cap at 3.2T. https://www.stateofeuropeantech.com/chapters/outcomes
Whereas this is saying the US "megacaps" ($200B+) are at 21T. https://www.cnbc.com/2025/09/05/tech-megacaps-worth-market-c...
Which puts the entire EU tech market at 15% of the US megacaps. Not even the entire market.
